Not all mice are handled by the kernel. + Instead there is a two layer abstraction. + + + + The kernel mouse drivers and userspace drivers for the serial mice are + all managed by a system daemon called gpm + - the general purpose mouse driver. gpm + handles cutting and pasting on the text consoles. It provides a + general library for mouse-aware applications and it handles the + sharing of mouse services with the + X Window System user interface. + + + Sometimes a mouse speaks a sufficiently convoluted protocol that the + protocol is handled by Gpm itself. Most + of the mouse drivers follow a common interface called the bus mouse + protocol. + + + Each read from a bus mouse interface device returns a block of data. + The first three bytes of each read are defined as follows: + + + Mouse Data Encoding + + + + Byte 0 + 0x80 + the buttons currently down. + + + Byte 1 + A signed value for the shift in X position + + + Byte 2 + A signed value for the shift in Y position + + + +
+ + An application can choose to read more than 3 bytes. The rest of the + bytes will be zero, or may optionally return some additional + device-specific information. + + + The position values are truncated if they exceed the 8bit range (that + is -127 <= delta <= 127). While the value -128 does fit into a + byte is not allowed. + + + The buttons are numbered left to right as + 0, 1, 2, 3.. and each button sets the relevant bit. So a user pressing + the left and right button of a three button mouse will set bits 0 and 2. + + + All mice are required to support the poll + operation. Indeed pretty much every user of a mouse device uses + poll to wait for mouse events to occur. + + + Finally the mice support asynchronous I/O. This is a topic we have not + yet covered but which I will explain after looking at a simple mouse + driver. + + + + + A simple mouse driver + + First we will need the set up functions for our mouse device. To keep + this simple our imaginary mouse device has three I/O ports fixed at I/O + address 0x300 and always lives on interrupt 5. The ports will be the X + position, the Y position and the buttons in that order. + + + +#define OURMOUSE_BASE 0x300 + +static struct miscdevice our_mouse = { + OURMOUSE_MINOR, "ourmouse", &our_mouse_fops +}; + +__init ourmouse_init(void) +{ + + if (request_region(OURMOUSE_BASE, 3, "ourmouse") < 0) { + printk(KERN_ERR "ourmouse: request_region failed.\n"); + return -ENODEV; + } + + if (misc_register(&our_mouse) < 0) { + printk(KERN_ERR "ourmouse: cannot register misc device.\n"); + release_region(OURMOUSE_BASE, 3); + return -EBUSY; + } + + return 0; +} + + + + The miscdevice is new here. Linux normally + parcels devices out by major number, and each device has 256 units. + For things like mice this is extremely wasteful so a device exists + which is used to accumulate all the odd individual devices that + computers tend to have. + + + Minor numbers in this space are allocated by a central source, although + you can look in the kernel Documentation/devices.txt + file and pick a free one for development use. This kernel file also + carries instructions for registering a device. This may change over time + so it is a good idea to obtain a current copy of this file first. + + + Our code then is fairly simple. We reserve our I/O address space with + request_region, checking to make sure that it succeeded (i.e. the + space wasn't reserved by anyone else). + + + Then we ask the misc driver to allocate our minor device number. We also + hand it our name (which is used in + /proc/misc) and a set of file + operations that are to be used. The file operations work exactly like the + file operations you would register for a normal character device. The misc + device itself is simply acting as a redirector for requests. + Since misc_register can fail, it is important to check for failure + and act accordingly (which in the case of a mouse driver is to abort, + since you can't use the mouse without a working device node). + + + Next, in order to be able to use and test our code we need to add some + module code to support it. This too is fairly simple: + + +#ifdef MODULE + +int init_module(void) +{ + if(ourmouse_init()<0) + return -ENODEV: + return 0; +} + +void cleanup_module(void) +{ + misc_deregister(&our_mouse); + free_region(OURMOUSE_BASE, 3); +} + + +#endif + + + + The module code provides the normal two functions. The + init_module function is called when the module is + loaded. In our case it simply calls the initialising function we wrote + and returns an error if this fails. This ensures the module will only + be loaded if it was successfully set up. + + + The cleanup_module function is called when the + module is unloaded. We give the miscellaneous device entry back, and + then free our I/O resources. If we didn't free the I/O resources then + the next time the module loaded it would think someone else had its I/O + space. + + + Once the misc_deregister has been called any + attempts to open the mouse device will fail with the error + ENODEV (No such device). + + + Next we need to fill in our file operations. A mouse doesn't need many + of these. We need to provide open, release, read and poll. That makes + for a nice simple structure: + + + +struct file_operations our_mouse_fops = { + owner: THIS_MODULE, /* Automatic usage management */ + read: read_mouse, /* You can read a mouse */ + write: write_mouse, /* This won't do a lot */ + poll: poll_mouse, /* Poll */ + open: open_mouse, /* Called on open */ + release: close_mouse, /* Called on close */ +}; + + + + There is nothing particularly special needed here. We provide functions + for all the relevant or required operations and little else. There is + nothing stopping us providing an ioctl function for this mouse. Indeed + if you have a configurable mouse it may be very appropriate to provide + configuration interfaces via ioctl calls. + + + The syntax we use is not standard C as such. GCC provides the ability + to initialise fields by name, and this generally makes the method table + much easier to read than counting through NULL pointers and remembering + the order by hand. + + + The owner field is used to manage the locking of module load an + unloading. It is obviously important that a module is not unloaded while + in use. When your device is opened the module specified by "owner" is + locked. When it is finally released the module is unlocked. + + + The open and close routines need to manage enabling and disabling the + interrupts for the mouse as well as stopping the mouse being unloaded + when it is no longer required. + + + +static int mouse_users = 0; /* User count */ +static int mouse_dx = 0; /* Position changes */ +static int mouse_dy = 0; +static int mouse_event = 0; /* Mouse has moved */ + +static int open_mouse(struct inode *inode, struct file *file) +{ + if(mouse_users++) + return 0; + + if(request_irq(mouse_intr, OURMOUSE_IRQ, 0, "ourmouse", NULL)) + { + mouse_users--; + return -EBUSY; + } + mouse_dx = 0; + mouse_dy = 0; + mouse_event = 0; + mouse_buttons = 0; + return 0; +} + + + The open function has to do a small amount of housework. We keep a count + of the number of times the mouse is open. This is because we do not want + to request the interrupt multiple times. If the mouse has at least one + user then it is set up and we simply add to the user count and return + 0 for success. + + + We grab the interrupt and thus start mouse interrupts. If the interrupt + has been borrowed by some other driver then request_irq + will fail and we will return an error. If we were capable of sharing an + interrupt line we would specify SA_SHIRQ instead of + zero. Provided that everyone claiming an interrupt + sets this flag, they get to share the line. PCI can + share interrupts, ISA normally however cannot. + + + We do the housekeeping. We make the current mouse position the starting + point for accumulated changes and declare that nothing has happened + since the mouse driver was opened. + + + The release function needs to unwind all these: + + +static int close_mouse(struct inode *inode, struct file *file) +{ + if(--mouse_users) + return 0; + free_irq(OURMOUSE_IRQ, NULL); + return 0; +} + + + We count off a user and provided that there are still other users need + take no further action. The last person closing the mouse causes us to + free up the interrupt. This stops interrupts from the mouse from using + our CPU time, and ensures that the mouse can now be unloaded. + + + We can fill in the write handler at this point as the write function for + our mouse simply declines to allow writes: + + + +static ssize_t write_mouse(struct file *file, const char *buffer, size_t + count, loff_t *ppos) +{ + return -EINVAL; +} + + + + This is pretty much self-explanatory. Whenever you write you get told + it was an invalid function. + + + To make the poll and read functions work we have to consider how we + handle the mouse interrupt. + + + +static struct wait_queue *mouse_wait; +static spinlock_t mouse_lock = SPIN_LOCK_UNLOCKED; + +static void ourmouse_interrupt(int irq, void *dev_id, struct pt_regs *regs) +{ + char delta_x; + char delta_y; + unsigned char new_buttons; + + delta_x = inb(OURMOUSE_BASE); + delta_y = inb(OURMOUSE_BASE+1); + new_buttons = inb(OURMOUSE_BASE+2); + + if(delta_x || delta_y || new_buttons != mouse_buttons) + { + /* Something happened */ + + spin_lock(&mouse_lock); + mouse_event = 1; + mouse_dx += delta_x; + mouse_dy += delta_y; + mouse_buttons = new_buttons; + spin_unlock(&mouse_lock); + + wake_up_interruptible(&mouse_wait); + } +} + + + + The interrupt handler reads the mouse status. The next thing we do is + to check whether something has changed. If the mouse was smart it would + only interrupt us if something had changed, but let's assume our mouse + is stupid as most mice actually tend to be. + + + If the mouse has changed we need to update the status variables. What we + don't want is the mouse functions reading these variables to read them + during a change. We add a spinlock that protects these variables while we + play with them. + + + If a change has occurred we also need to wake sleeping processes, so we + add a wakeup call and a wait_queue to use when + we wish to await a mouse event. + + + Now we have the wait queue we can implement the poll function for the + mouse relatively easily: + + + +static unsigned int mouse_poll(struct file *file, poll_table *wait) +{ + poll_wait(file, &mouse_wait, wait); + if(mouse_event) + return POLLIN | POLLRDNORM; + return 0; +} + + + + This is fairly standard poll code. First we add the wait queue to the + list of queues we want to monitor for an event. Secondly we check if an + event has occurred. We only have one kind of event - the + mouse_event flag tells us that something happened. + We know that this something can only be mouse data. We return the flags + indicating input and normal reading will succeed. + + + You may be wondering what happens if the function returns saying 'no + event yet'. In this case the wake up from the wait queue we added to + the poll table will cause the function to be called again. Eventually + we will be woken up and have an event ready. At this point the + poll call will exit back to the user. + + + After the poll completes the user will want to read the data. We now + need to think about how our mouse_read function + will work: + + +static ssize_t mouse_read(struct file *file, char *buffer, + size_t count, loff_t *pos) +{ + int dx, dy; + unsigned char button; + unsigned long flags; + int n; + + if(count<3) + return -EINVAL; + + /* + * Wait for an event + */ + + while(!mouse_event) + { + if(file->f_flags&O_NDELAY) + return -EAGAIN; + interruptible_sleep_on(&mouse_wait); + if(signal_pending(current)) + return -ERESTARTSYS; + } + + + + We start by validating that the user is reading enough data. We could + handle partial reads if we wanted but it isn't terribly useful and the + mouse drivers don't bother to try. + + + Next we wait for an event to occur. The loop is fairly standard event + waiting in Linux. Having checked that the event has not yet occurred, we + then check if an event is pending and if not we need to sleep. + + + A user process can set the O_NDELAY flag on a file + to indicate that it wishes to be told immediately if no event is + pending. We check this and give the appropriate error if so. + + + Next we sleep until the mouse or a signal awakens us. A signal will + awaken us as we have used wakeup_interruptible. + This is important as it means a user can kill processes waiting for + the mouse - clearly a desirable property. If we are interrupted we + exit the call and the kernel will then process signals and maybe + restart the call again - from the beginning. + + + This code contains a classic Linux bug. All will be revealed later in this + article as well as explanations for how to avoid it. + + + /* Grab the event */ + + spinlock_irqsave(&mouse_lock, flags); + + dx = mouse_dx; + dy = mouse_dy; + button = mouse_buttons; + + if(dx<=-127) + dx=-127; + if(dx>=127) + dx=127; + if(dy<=-127) + dy=-127; + if(dy>=127) + dy=127; + + mouse_dx -= dx; + mouse_dy -= dy; + + if(mouse_dx == 0 && mouse_dy == 0) + mouse_event = 0; + + spin_unlock_irqrestore(&mouse_lock, flags); + + + This is the next stage. Having established that there is an event + going, we capture it. To be sure that the event is not being updated + as we capture it we also take the spinlock and thus prevent parallel + updates. Note here we use spinlock_irqsave. We + need to disable interrupts on the local processor otherwise bad things + will happen. + + + What will occur is that we take the spinlock. While we hold the lock + an interrupt will occur. At this point our interrupt handler will try + and take the spinlock. It will sit in a loop waiting for the read + routine to release the lock. However because we are sitting in a loop + in the interrupt handler we will never release the lock. The machine + hangs and the user gets upset. + + + By blocking the interrupt on this processor we ensure that the lock + holder will always give the lock back without deadlocking. + + + There is a little cleverness in the reporting mechanism too. We can + only report a move of 127 per read. We don't however want to lose + information by throwing away further movement. Instead we keep + returning as much information as possible. Each time we return a + report we remove the amount from the pending movement in + mouse_dx and mouse_dy. Eventually + when these counts hit zero we clear the mouse_event + flag as there is nothing else left to report. + + + + if(put_user(button|0x80, buffer)) + return -EFAULT; + if(put_user((char)dx, buffer+1)) + return -EFAULT; + if(put_user((char)dy, buffer+2)) + return -EFAULT; + + for(n=3; n < count; n++) + if(put_user(0x00, buffer+n)) + return -EFAULT; + + return count; +} + + + + Finally we must put the results in the user supplied buffer. We cannot + do this while holding the lock as a write to user memory may sleep. + For example the user memory may be residing on disk at this instant. + Thus we did our computation beforehand and now copy the data. Each + put_user call is filling in one byte of the buffer. + If it returns an error we inform the program that it passed us an + invalid buffer and abort. + + + Having written the data we blank the rest of the buffer that was read + and report the read as being successful. + + + + + Debugging the mouse driver + + + We now have an almost perfectly usable mouse driver. If you were to + actually try and use it however you would eventually find a couple of + problems with it. A few programs will also not work with as it does not + yet support asynchronous I/O. + + + First let us look at the bugs. The most obvious one isn't really a driver + bug but a failure to consider the consequences. Imagine you bumped the + mouse hard by accident and sent it skittering across the desk. The mouse + interrupt routine will add up all that movement and report it in steps of + 127 until it has reported all of it. Clearly there is a point beyond + which mouse movement isn't worth reporting. We need to add this as a + limit to the interrupt handler: + + + +static void ourmouse_interrupt(int irq, void *dev_id, struct pt_regs *regs) +{ + char delta_x; + char delta_y; + unsigned char new_buttons; + + delta_x = inb(OURMOUSE_BASE); + delta_y = inb(OURMOUSE_BASE+1); + new_buttons = inb(OURMOUSE_BASE+2); + + if(delta_x || delta_y || new_buttons != mouse_buttons) + { + /* Something happened */ + + spin_lock(&mouse_lock); + mouse_event = 1; + mouse_dx += delta_x; + mouse_dy += delta_y; + + if(mouse_dx < -4096) + mouse_dx = -4096; + if(mouse_dx > 4096) + mouse_dx = 4096; + + if(mouse_dy < -4096) + mouse_dy = -4096; + if(mouse_dy > 4096) + mouse_dy = 4096; + + mouse_buttons = new_buttons; + spin_unlock(&mouse_lock); + + wake_up_interruptible(&mouse_wait); + } +} + + + + By adding these checks we limit the range of accumulated movement to + something sensible. + + + The second bug is a bit more subtle, and that is perhaps why this is + such a common mistake. Remember, I said the waiting loop for the read + handler had a bug in it. Think about what happens when we execute: + + + + while(!mouse_event) + { + + + + and an interrupt occurs at this point here. This causes a mouse movement + and wakes up the queue. + + + + interruptible_sleep_on(&mouse_wait); + + + + Now we sleep on the queue. We missed the wake up and the application + will not see an event until the next mouse event occurs. This will + lead to just the odd instance when a mouse button gets delayed. The + consequences to the user will probably be almost undetectable with a + mouse driver. With other drivers this bug could be a lot more severe. + + + There are two ways to solve this. The first is to disable interrupts + during the testing and the sleep. This works because when a task sleeps + it ceases to disable interrupts, and when it resumes it disables them + again. Our code thus becomes: + + + + save_flags(flags); + cli(); + + while(!mouse_event) + { + if(file->f_flags&O_NDELAY) + { + restore_flags(flags); + return -EAGAIN; + } + interruptible_sleep_on(&mouse_wait); + if(signal_pending(current)) + { + restore_flags(flags); + return -ERESTARTSYS; + } + } + restore_flags(flags); + + + + This is the sledgehammer approach. It works but it means we spend a + lot more time turning interrupts on and off. It also affects + interrupts globally and has bad properties on multiprocessor machines + where turning interrupts off globally is not a simple operation, but + instead involves kicking each processor, waiting for them to disable + interrupts and reply. + + + The real problem is the race between the event testing and the sleeping. + We can avoid that by using the scheduling functions more directly. + Indeed this is the way they generally should be used for an interrupt. + + + + struct wait_queue wait = { current, NULL }; + + add_wait_queue(&mouse_wait, &wait); + set_current_state(TASK_INTERRUPTIBLE); + + while(!mouse_event) + { + if(file->f_flags&O_NDELAY) + { + remove_wait_queue(&mouse_wait, &wait); + set_current_state(TASK_RUNNING); + return -EWOULDBLOCK; + } + if(signal_pending(current)) + { + remove_wait_queue(&mouse_wait, &wait); + current->state = TASK_RUNNING; + return -ERESTARTSYS; + } + schedule(); + set_current_state(TASK_INTERRUPTIBLE); + } + + remove_wait_wait(&mouse_wait, &wait); + set_current_state(TASK_RUNNING); + + + + At first sight this probably looks like deep magic. To understand how + this works you need to understand how scheduling and events work on + Linux. Having a good grasp of this is one of the keys to writing clean + efficient device drivers. + + + add_wait_queue does what its name suggests. It adds + an entry to the mouse_wait list. The entry in this + case is the entry for our current process (current + is the current task pointer). + + + So we start by adding an entry for ourself onto the + mouse_wait list. This does not put us to sleep + however. We are merely tagged onto the list. + + + Next we set our status to TASK_INTERRUPTIBLE. Again + this does not mean we are now asleep. This flag says what should happen + next time the process sleeps. TASK_INTERRUPTIBLE says + that the process should not be rescheduled. It will run from now until it + sleeps and then will need to be woken up. + + + The wakeup_interruptible call in the interrupt + handler can now be explained in more detail. This function is also very + simple. It goes along the list of processes on the queue it is given and + any that are marked as TASK_INTERRUPTIBLE it changes + to TASK_RUNNING and tells the kernel that new + processes are runnable. + + + Behind all the wrappers in the original code what is happening is this + + + + + + We add ourself to the mouse wait queue + + + + + We mark ourself as sleeping + + + + + We ask the kernel to schedule tasks again + + + + + The kernel sees we are asleep and schedules someone else. + + + + + The mouse interrupt sets our state to TASK_RUNNING + and makes a note that the kernel should reschedule tasks + + + + + The kernel sees we are running again and continues our execution + + + + + This is why the apparent magic works. Because we mark ourself as + TASK_INTERRUPTIBLE and as we add ourselves + to the queue before we check if there are events pending, the race + condition is removed. + + + Now if an interrupt occurs after we check the queue status and before + we call the schedule function in order to sleep, + things work out. Instead of missing an event, we are set back to + TASK_RUNNING by the mouse interrupt. We still call + schedule but it will continue running our task. + We go back around the loop and this time there may be an event. + + + There will not always be an event. Thus we set ourselves back to + TASK_INTERRUPTIBLE before resuming the loop. + Another process doing a read may already have cleared the event flag, + and if so we will need to go back to sleep again. Eventually we will + get our event and escape. + + + Finally when we exit the loop we remove ourselves from the + mouse_wait queue as we are no longer interested + in mouse events, and we set ourself back to + TASK_RUNNABLE as we do not wish to go to sleep + again just yet. + + + Note + + This isn't an easy topic. Don't be afraid to reread the description a + few times and also look at other device drivers to see how it works. + Finally if you can't grasp it just yet, you can use the code as + boilerplate to write other drivers and trust me instead. + + + + + + Asynchronous I/O + + This leaves the missing feature - Asynchronous I/O. Normally UNIX + programs use the poll call (or its variant form + select) to wait for an event to occur on one of + multiple input or output devices. This model works well for most tasks + but because poll and select + wait for an event isn't suitable for tasks that are also continually + doing computation work. Such programs really want the kernel to kick + them when something happens rather than watch for events. + + + Poll is akin to having a row of lights in front of you. You can see at a + glance which ones if any are lit. You cannot however get anything useful + done while watching them. Asynchronous I/O uses signals which work more + like a door bell. Instead of you watching, it tells you that something + is up. + + + Asynchronous I/O sends the signal SIGIO to a user process when the I/O + events occur. In this case that means when people move the mouse. The + SIGIO signal causes the user process to jump to its signal handler and + execute code in that handler before returning to whatever was going on + previously. It is the application equivalent of an interrupt handler. + + + Most of the code needed for this operation is common to all its users. + The kernel provides a simple set of functions for managing asynchronous + I/O. + + + Our first job is to allow users to set asynchronous I/O on file handles. + To do that we need to add a new function to the file operations table for + our mouse: + + + +struct file_operations our_mouse_fops = { + owner: THIS_MODULE + read: read_mouse, /* You can read a mouse */ + write: write_mouse, /* This won't do a lot */ + poll: poll_mouse, /* Poll */ + open: open_mouse, /* Called on open */ + release: close_mouse, /* Called on close */ + fasync: fasync_mouse, /* Asynchronous I/O */ +}; + + + + Once we have installed this entry the kernel knows we support + asynchronous I/O and will allow all the relevant operations on the + device. Whenever a user adds or removes asynchronous I/O notification + on a file handle it calls our fasync_mouse routine + we just added. This routine uses the helper functions to keep the queue + of handles up to date: + + + +static struct fasync_struct *mouse_fasync = NULL; + +static int fasync_mouse(int fd, struct file *filp, int on) +{ + int retval = fasync_helper(fd, filp, on, &mouse_fasync); + + if (retval < 0) + return retval; + return 0; +} + + + + The fasync helper adds and deletes entries by managing the supplied + list. We also need to remove entries from this list when the file is + closed. This requires we add one line to our close function: + + + +static int close_mouse(struct inode *inode, struct file *file) +{ + fasync_mouse(-1, file, 0) + if(--mouse_users) + return 0; + free_irq(OURMOUSE_IRQ, NULL); + return 0; +} + + + + When we close the file we now call our own fasync handler as if the + user had requested that this file cease to be used for asynchronous + I/O. This rather neatly cleans up any loose ends. We certainly don't + wait to deliver a signal for a file that no longer exists. + + + At this point the mouse driver supports all the asynchronous I/O + operations, and applications using them will not error. They won't + however work yet. We need to actually send the signals. Again the + kernel provides a function for handling this. + + + We update our interrupt handler a little: + + + +static void ourmouse_interrupt(int irq, void *dev_id, struct pt_regs *regs) +{ + char delta_x; + char delta_y; + unsigned char new_buttons; + + delta_x = inb(OURMOUSE_BASE); + delta_y = inb(OURMOUSE_BASE+1); + new_buttons = inb(OURMOUSE_BASE+2); + + if(delta_x || delta_y || new_buttons != mouse_buttons) + { + /* Something happened */ + + spin_lock(&mouse_lock); + mouse_event = 1; + mouse_dx += delta_x; + mouse_dy += delta_y; + + if(mouse_dx < -4096) + mouse_dx = -4096; + if(mouse_dx > 4096) + mouse_dx = 4096; + + if(mouse_dy < -4096) + mouse_dy = -4096; + if(mouse_dy > 4096) + mouse_dy = 4096; + + mouse_buttons = new_buttons; + spin_unlock(&mouse_lock); + + /* Now we do asynchronous I/O */ + kill_fasync(&mouse_fasync, SIGIO); + + wake_up_interruptible(&mouse_wait); + } +} + + + + The new code simply calls the kill_fasync routine + provided by the kernel if the queue is non-empty. This sends the + required signal (SIGIO in this case) to the process each file handle + says should be informed about the exciting new mouse movement that + just happened. + + + With this in place and the bugs in the original version fixed, you now + have a fully functional mouse driver using the bus mouse protocol. It + will work with the X window system, will work + with GPM and should work with every other + application you need. Doom is of course the + ideal way to test your new mouse driver is functioning properly. Be sure + to test it thoroughly. + + + + diff --git a/Documentation/DocBook/mtdnand.tmpl b/Documentation/DocBook/mtdnand.tmpl deleted file mode 100644 index 435bb5245..000000000 --- a/Documentation/DocBook/mtdnand.tmpl +++ /dev/null @@ -1,1318 +0,0 @@ - - - - - MTD NAND Driver Programming Interface - - - - Thomas - Gleixner - -

For a list of functions which can be overridden by the board - driver see the documentation of the nand_chip structure. - - - Multiple chip control - - The nand driver can control chip arrays. Therefor the - board driver must provide an own select_chip function. This - function must (de)select the requested chip. - The function pointer in the nand_chip structure must - be set before calling nand_scan(). The maxchip parameter - of nand_scan() defines the maximum number of chips to - scan for. Make sure that the select_chip function can - handle the requested number of chips. - - - The nand driver concatenates the chips to one virtual - chip and provides this virtual chip to the MTD layer. - - - Note: The driver can only handle linear chip arrays - of equally sized chips. There is no support for - parallel arrays which extend the buswidth. - - - GPIO based example - - -static void board_select_chip (struct mtd_info *mtd, int chip) -{ - /* Deselect all chips, set all nCE pins high */ - GPIO(BOARD_NAND_NCE) |= 0xff; - if (chip >= 0) - GPIO(BOARD_NAND_NCE) &= ~ (1 << chip); -} - - - Address lines based example. - Its assumed that the nCE pins are connected to an - address decoder. - - -static void board_select_chip (struct mtd_info *mtd, int chip) -{ - struct nand_chip *this = (struct nand_chip *) mtd->priv; - - /* Deselect all chips */ - this->IO_ADDR_R &= ~BOARD_NAND_ADDR_MASK; - this->IO_ADDR_W &= ~BOARD_NAND_ADDR_MASK; - switch (chip) { - case 0: - this->IO_ADDR_R |= BOARD_NAND_ADDR_CHIP0; - this->IO_ADDR_W |= BOARD_NAND_ADDR_CHIP0; - break; - .... - case n: - this->IO_ADDR_R |= BOARD_NAND_ADDR_CHIPn; - this->IO_ADDR_W |= BOARD_NAND_ADDR_CHIPn; - break; - } -} - - - - Hardware ECC support - - Functions and constants - - The nand driver supports three different types of - hardware ECC. - - NAND_ECC_HW3_256 - Hardware ECC generator providing 3 bytes ECC per - 256 byte. - - NAND_ECC_HW3_512 - Hardware ECC generator providing 3 bytes ECC per - 512 byte. - - NAND_ECC_HW6_512 - Hardware ECC generator providing 6 bytes ECC per - 512 byte. - - NAND_ECC_HW8_512 - Hardware ECC generator providing 6 bytes ECC per - 512 byte. - - - If your hardware generator has a different functionality - add it at the appropriate place in nand_base.c - - - The board driver must provide following functions: - - enable_hwecc - This function is called before reading / writing to - the chip. Reset or initialize the hardware generator - in this function. The function is called with an - argument which let you distinguish between read - and write operations. - - calculate_ecc - This function is called after read / write from / to - the chip. Transfer the ECC from the hardware to - the buffer. If the option NAND_HWECC_SYNDROME is set - then the function is only called on write. See below. - - correct_data - In case of an ECC error this function is called for - error detection and correction. Return 1 respectively 2 - in case the error can be corrected. If the error is - not correctable return -1. If your hardware generator - matches the default algorithm of the nand_ecc software - generator then use the correction function provided - by nand_ecc instead of implementing duplicated code. - - - - - - Hardware ECC with syndrome calculation - - Many hardware ECC implementations provide Reed-Solomon - codes and calculate an error syndrome on read. The syndrome - must be converted to a standard Reed-Solomon syndrome - before calling the error correction code in the generic - Reed-Solomon library. - - - The ECC bytes must be placed immidiately after the data - bytes in order to make the syndrome generator work. This - is contrary to the usual layout used by software ECC. The - seperation of data and out of band area is not longer - possible. The nand driver code handles this layout and - the remaining free bytes in the oob area are managed by - the autoplacement code. Provide a matching oob-layout - in this case. See rts_from4.c and diskonchip.c for - implementation reference. In those cases we must also - use bad block tables on FLASH, because the ECC layout is - interferring with the bad block marker positions. - See bad block table support for details. - - - - - Bad block table support - - Most NAND chips mark the bad blocks at a defined - position in the spare area. Those blocks must - not be erased under any circumstances as the bad - block information would be lost. - It is possible to check the bad block mark each - time when the blocks are accessed by reading the - spare area of the first page in the block. This - is time consuming so a bad block table is used. - - - The nand driver supports various types of bad block - tables. - - Per device - The bad block table contains all bad block information - of the device which can consist of multiple chips. - - Per chip - A bad block table is used per chip and contains the - bad block information for this particular chip. - - Fixed offset - The bad block table is located at a fixed offset - in the chip (device). This applies to various - DiskOnChip devices. - - Automatic placed - The bad block table is automatically placed and - detected either at the end or at the beginning - of a chip (device) - - Mirrored tables - The bad block table is mirrored on the chip (device) to - allow updates of the bad block table without data loss. - - - - - nand_scan() calls the function nand_default_bbt(). - nand_default_bbt() selects appropriate default - bad block table desriptors depending on the chip information - which was retrieved by nand_scan(). - - - The standard policy is scanning the device for bad - blocks and build a ram based bad block table which - allows faster access than always checking the - bad block information on the flash chip itself. - - - Flash based tables - - It may be desired or neccecary to keep a bad block table in FLASH. - For AG-AND chips this is mandatory, as they have no factory marked - bad blocks. They have factory marked good blocks. The marker pattern - is erased when the block is erased to be reused. So in case of - powerloss before writing the pattern back to the chip this block - would be lost and added to the bad blocks. Therefor we scan the - chip(s) when we detect them the first time for good blocks and - store this information in a bad block table before erasing any - of the blocks. - - - The blocks in which the tables are stored are procteted against - accidental access by marking them bad in the memory bad block - table. The bad block table managment functions are allowed - to circumvernt this protection. - - - The simplest way to activate the FLASH based bad block table support - is to set the option NAND_USE_FLASH_BBT in the option field of - the nand chip structure before calling nand_scan(). For AG-AND - chips is this done by default. - This activates the default FLASH based bad block table functionality - of the NAND driver. The default bad block table options are - - Store bad block table per chip - Use 2 bits per block - Automatic placement at the end of the chip - Use mirrored tables with version numbers - Reserve 4 blocks at the end of the chip - - - - - User defined tables - - User defined tables are created by filling out a - nand_bbt_descr structure and storing the pointer in the - nand_chip structure member bbt_td before calling nand_scan(). - If a mirror table is neccecary a second structure must be - created and a pointer to this structure must be stored - in bbt_md inside the nand_chip structure. If the bbt_md - member is set to NULL then only the main table is used - and no scan for the mirrored table is performed. - - - The most important field in the nand_bbt_descr structure - is the options field. The options define most of the - table properties. Use the predefined constants from - nand.h to define the options. - - Number of bits per block - The supported number of bits is 1, 2, 4, 8. - Table per chip - Setting the constant NAND_BBT_PERCHIP selects that - a bad block table is managed for each chip in a chip array. - If this option is not set then a per device bad block table - is used. - Table location is absolute - Use the option constant NAND_BBT_ABSPAGE and - define the absolute page number where the bad block - table starts in the field pages. If you have selected bad block - tables per chip and you have a multi chip array then the start page - must be given for each chip in the chip array. Note: there is no scan - for a table ident pattern performed, so the fields - pattern, veroffs, offs, len can be left uninitialized - Table location is automatically detected - The table can either be located in the first or the last good - blocks of the chip (device). Set NAND_BBT_LASTBLOCK to place - the bad block table at the end of the chip (device). The - bad block tables are marked and identified by a pattern which - is stored in the spare area of the first page in the block which - holds the bad block table. Store a pointer to the pattern - in the pattern field. Further the length of the pattern has to be - stored in len and the offset in the spare area must be given - in the offs member of the nand_bbt_descr stucture. For mirrored - bad block tables different patterns are mandatory. - Table creation - Set the option NAND_BBT_CREATE to enable the table creation - if no table can be found during the scan. Usually this is done only - once if a new chip is found. - Table write support - Set the option NAND_BBT_WRITE to enable the table write support. - This allows the update of the bad block table(s) in case a block has - to be marked bad due to wear. The MTD interface function block_markbad - is calling the update function of the bad block table. If the write - support is enabled then the table is updated on FLASH. - - Note: Write support should only be enabled for mirrored tables with - version control. - - Table version control - Set the option NAND_BBT_VERSION to enable the table version control. - It's highly recommended to enable this for mirrored tables with write - support. It makes sure that the risk of loosing the bad block - table information is reduced to the loss of the information about the - one worn out block which should be marked bad. The version is stored in - 4 consecutive bytes in the spare area of the device. The position of - the version number is defined by the member veroffs in the bad block table - descriptor. - Save block contents on write - - In case that the block which holds the bad block table does contain - other useful information, set the option NAND_BBT_SAVECONTENT. When - the bad block table is written then the whole block is read the bad - block table is updated and the block is erased and everything is - written back. If this option is not set only the bad block table - is written and everything else in the block is ignored and erased. - - Number of reserved blocks - - For automatic placement some blocks must be reserved for - bad block table storage. The number of reserved blocks is defined - in the maxblocks member of the babd block table description structure. - Reserving 4 blocks for mirrored tables should be a reasonable number. - This also limits the number of blocks which are scanned for the bad - block table ident pattern. - - - - - - - Spare area (auto)placement - - The nand driver implements different possibilities for - placement of filesystem data in the spare area, - - Placement defined by fs driver - Automatic placement - - The default placement function is automatic placement. The - nand driver has built in default placement schemes for the - various chiptypes. If due to hardware ECC functionality the - default placement does not fit then the board driver can - provide a own placement scheme. - - - File system drivers can provide a own placement scheme which - is used instead of the default placement scheme. - - - Placement schemes are defined by a nand_oobinfo structure - -struct nand_oobinfo { - int useecc; - int eccbytes; - int eccpos[24]; - int oobfree[8][2]; -}; - - - useecc - The useecc member controls the ecc and placement function. The header - file include/mtd/mtd-abi.h contains constants to select ecc and - placement. MTD_NANDECC_OFF switches off the ecc complete. This is - not recommended and available for testing and diagnosis only. - MTD_NANDECC_PLACE selects caller defined placement, MTD_NANDECC_AUTOPLACE - selects automatic placement. - - eccbytes - The eccbytes member defines the number of ecc bytes per page. - - eccpos - The eccpos array holds the byte offsets in the spare area where - the ecc codes are placed. - - oobfree - The oobfree array defines the areas in the spare area which can be - used for automatic placement. The information is given in the format - {offset, size}. offset defines the start of the usable area, size the - length in bytes. More than one area can be defined. The list is terminated - by an {0, 0} entry. - - - - - Placement defined by fs driver - - The calling function provides a pointer to a nand_oobinfo - structure which defines the ecc placement. For writes the - caller must provide a spare area buffer along with the - data buffer. The spare area buffer size is (number of pages) * - (size of spare area). For reads the buffer size is - (number of pages) * ((size of spare area) + (number of ecc - steps per page) * sizeof (int)). The driver stores the - result of the ecc check for each tuple in the spare buffer. - The storage sequence is - - - <spare data page 0><ecc result 0>...<ecc result n> - - - ... - - - <spare data page n><ecc result 0>...<ecc result n> - - - This is a legacy mode used by YAFFS1. - - - If the spare area buffer is NULL then only the ECC placement is - done according to the given scheme in the nand_oobinfo structure. - - - - Automatic placement - - Automatic placement uses the built in defaults to place the - ecc bytes in the spare area. If filesystem data have to be stored / - read into the spare area then the calling function must provide a - buffer. The buffer size per page is determined by the oobfree array in - the nand_oobinfo structure. - - - If the spare area buffer is NULL then only the ECC placement is - done according to the default builtin scheme. - - - - User space placement selection - - All non ecc functions like mtd->read and mtd->write use an internal - structure, which can be set by an ioctl. This structure is preset - to the autoplacement default. - - ioctl (fd, MEMSETOOBSEL, oobsel); - - oobsel is a pointer to a user supplied structure of type - nand_oobconfig. The contents of this structure must match the - criteria of the filesystem, which will be used.

With the introduction of RCU -in linux kernel, this was worked around by making -the look-up of path components during path walking lock-free. - - -Safe lock-free look-up of dcache hash table -=========================================== - -Dcache is a complex data structure with the hash table entries -also linked together in other lists. In 2.4 kernel, dcache_lock -protected all the lists. We applied RCU only on hash chain -walking. The rest of the lists are still protected by dcache_lock. -Some of the important changes are : - -1. The deletion from hash chain is done using hlist_del_rcu() macro which - doesn't initialize next pointer of the deleted dentry and this - allows us to walk safely lock-free while a deletion is happening. - -2. Insertion of a dentry into the hash table is done using - hlist_add_head_rcu() which take care of ordering the writes - - the writes to the dentry must be visible before the dentry - is inserted. This works in conjuction with hlist_for_each_rcu() - while walking the hash chain. The only requirement is that - all initialization to the dentry must be done before hlist_add_head_rcu() - since we don't have dcache_lock protection while traversing - the hash chain. This isn't different from the existing code. - -3. The dentry looked up without holding dcache_lock by cannot be - returned for walking if it is unhashed. It then may have a NULL - d_inode or other bogosity since RCU doesn't protect the other - fields in the dentry. We therefore use a flag DCACHE_UNHASHED to - indicate unhashed dentries and use this in conjunction with a - per-dentry lock (d_lock). Once looked up without the dcache_lock, - we acquire the per-dentry lock (d_lock) and check if the - dentry is unhashed. If so, the look-up is failed. If not, the - reference count of the dentry is increased and the dentry is returned. - -4. Once a dentry is looked up, it must be ensured during the path - walk for that component it doesn't go away. In pre-2.5.10 code, - this was done holding a reference to the dentry. dcache_rcu does - the same. In some sense, dcache_rcu path walking looks like - the pre-2.5.10 version. - -5. All dentry hash chain updations must take the dcache_lock as well as - the per-dentry lock in that order. dput() does this to ensure - that a dentry that has just been looked up in another CPU - doesn't get deleted before dget() can be done on it. - -6. There are several ways to do reference counting of RCU protected - objects. One such example is in ipv4 route cache where - deferred freeing (using call_rcu()) is done as soon as - the reference count goes to zero. This cannot be done in - the case of dentries because tearing down of dentries - require blocking (dentry_iput()) which isn't supported from - RCU callbacks. Instead, tearing down of dentries happen - synchronously in dput(), but actual freeing happens later - when RCU grace period is over. This allows safe lock-free - walking of the hash chains, but a matched dentry may have - been partially torn down. The checking of DCACHE_UNHASHED - flag with d_lock held detects such dentries and prevents - them from being returned from look-up. - - -Maintaining POSIX rename semantics -================================== - -Since look-up of dentries is lock-free, it can race against -a concurrent rename operation. For example, during rename -of file A to B, look-up of either A or B must succeed. -So, if look-up of B happens after A has been removed from the -hash chain but not added to the new hash chain, it may fail. -Also, a comparison while the name is being written concurrently -by a rename may result in false positive matches violating -rename semantics. Issues related to race with rename are -handled as described below : - -1. Look-up can be done in two ways - d_lookup() which is safe - from simultaneous renames and __d_lookup() which is not. - If __d_lookup() fails, it must be followed up by a d_lookup() - to correctly determine whether a dentry is in the hash table - or not. d_lookup() protects look-ups using a sequence - lock (rename_lock). - -2. The name associated with a dentry (d_name) may be changed if - a rename is allowed to happen simultaneously. To avoid memcmp() - in __d_lookup() go out of bounds due to a rename and false - positive comparison, the name comparison is done while holding the - per-dentry lock. This prevents concurrent renames during this - operation. - -3. Hash table walking during look-up may move to a different bucket as - the current dentry is moved to a different bucket due to rename. - But we use hlists in dcache hash table and they are null-terminated. - So, even if a dentry moves to a different bucket, hash chain - walk will terminate. [with a list_head list, it may not since - termination is when the list_head in the original bucket is reached]. - Since we redo the d_parent check and compare name while holding - d_lock, lock-free look-up will not race against d_move(). - -4. There can be a theoritical race when a dentry keeps coming back - to original bucket due to double moves. Due to this look-up may - consider that it has never moved and can end up in a infinite loop. - But this is not any worse that theoritical livelocks we already - have in the kernel. - - -Important guidelines for filesystem developers related to dcache_rcu -==================================================================== - -1. Existing dcache interfaces (pre-2.5.62) exported to filesystem - don't change. Only dcache internal implementation changes. However - filesystems *must not* delete from the dentry hash chains directly - using the list macros like allowed earlier. They must use dcache - APIs like d_drop() or __d_drop() depending on the situation. - -2. d_flags is now protected by a per-dentry lock (d_lock). All - access to d_flags must be protected by it. - -3.

The rest of this section describes -how to install this driver when downloaded from the web site. - -First, you need to get a kernel with ACPI support up and running. -Please refer to http://acpi.sourceforge.net/ for help with this -step. How successful you will be depends a lot on you ThinkPad model, -the kernel you are using and any additional patches applied. The -kernel provided with your distribution may not be good enough. I -needed to compile a 2.6.7 kernel with the 20040715 ACPI patch to get -ACPI working reliably on my ThinkPad X40. Old ThinkPad models may not -be supported at all. - -Assuming you have the basic ACPI support working (e.g. you can see the -/proc/acpi directory), follow the following steps to install this -driver: - - - unpack the archive: - - tar xzvf ibm-acpi-x.y.tar.gz; cd ibm-acpi-x.y - - - compile the driver: - - make - - - install the module in your kernel modules directory: - - make install - - - load the module: - - modprobe ibm_acpi - -After loading the module, check the "dmesg" output for any error messages. - - -Features --------- - -The driver creates the /proc/acpi/ibm directory. There is a file under -that directory for each feature described below. Note that while the -driver is still in the alpha stage, the exact proc file format and -commands supported by the various features is guaranteed to change -frequently. - -Driver Version -- /proc/acpi/ibm/driver --------------------------------------- - -The driver name and version. No commands can be written to this file. - -Hot Keys -- /proc/acpi/ibm/hotkey ---------------------------------- - -Without this driver, only the Fn-F4 key (sleep button) generates an -ACPI event. With the driver loaded, the hotkey feature enabled and the -mask set (see below), the various hot keys generate ACPI events in the -following format: - - ibm/hotkey HKEY 00000080 0000xxxx - -The last four digits vary depending on the key combination pressed. -All labeled Fn-Fx key combinations generate distinct events. In -addition, the lid microswitch and some docking station buttons may -also generate such events. - -The following commands can be written to this file: - - echo enable > /proc/acpi/ibm/hotkey -- enable the hot keys feature - echo disable > /proc/acpi/ibm/hotkey -- disable the hot keys feature - echo 0xffff > /proc/acpi/ibm/hotkey -- enable all possible hot keys - echo 0x0000 > /proc/acpi/ibm/hotkey -- disable all possible hot keys - ... any other 4-hex-digit mask ... - echo reset > /proc/acpi/ibm/hotkey -- restore the original mask - -The bit mask allows some control over which hot keys generate ACPI -events. Not all bits in the mask can be modified. Not all bits that -can be modified do anything. Not all hot keys can be individually -controlled by the mask. Most recent ThinkPad models honor the -following bits (assuming the hot keys feature has been enabled): - - key bit behavior when set behavior when unset - - Fn-F3 always generates ACPI event - Fn-F4 always generates ACPI event - Fn-F5 0010 generate ACPI event enable/disable Bluetooth - Fn-F7 0040 generate ACPI event switch LCD and external display - Fn-F8 0080 generate ACPI event expand screen or none - Fn-F9 0100 generate ACPI event none - Fn-F12 always generates ACPI event - -Some models do not support all of the above. For example, the T30 does -not support Fn-F5 and Fn-F9. Other models do not support the mask at -all. On those models, hot keys cannot be controlled individually. - -Note that enabling ACPI events for some keys prevents their default -behavior. For example, if events for Fn-F5 are enabled, that key will -no longer enable/disable Bluetooth by itself. This can still be done -from an acpid handler for the ibm/hotkey event. - -Note also that not all Fn key combinations are supported through -ACPI. For example, on the X40, the brightness, volume and "Access IBM" -buttons do not generate ACPI events even with this driver. They *can* -be used through the "ThinkPad Buttons" utility, see -http://www.nongnu.org/tpb/ - -Bluetooth -- /proc/acpi/ibm/bluetooth -------------------------------------- - -This feature shows the presence and current state of a Bluetooth -device. If Bluetooth is installed, the following commands can be used: - - echo enable > /proc/acpi/ibm/bluetooth - echo disable > /proc/acpi/ibm/bluetooth - -Video output control -- /proc/acpi/ibm/video --------------------------------------------- - -This feature allows control over the devices used for video output - -LCD, CRT or DVI (if available). The following commands are available: - - echo lcd_enable > /proc/acpi/ibm/video - echo lcd_disable > /proc/acpi/ibm/video - echo crt_enable > /proc/acpi/ibm/video - echo crt_disable > /proc/acpi/ibm/video - echo dvi_enable > /proc/acpi/ibm/video - echo dvi_disable > /proc/acpi/ibm/video - echo auto_enable > /proc/acpi/ibm/video - echo auto_disable > /proc/acpi/ibm/video - echo expand_toggle > /proc/acpi/ibm/video - echo video_switch > /proc/acpi/ibm/video - -Each video output device can be enabled or disabled individually. -Reading /proc/acpi/ibm/video shows the status of each device. - -Automatic video switching can be enabled or disabled. When automatic -video switching is enabled, certain events (e.g. opening the lid, -docking or undocking) cause the video output device to change -automatically. While this can be useful, it also causes flickering -and, on the X40, video corruption. By disabling automatic switching, -the flickering or video corruption can be avoided. - -The video_switch command cycles through the available video outputs -(it sumulates the behavior of Fn-F7). - -Video expansion can be toggled through this feature. This controls -whether the display is expanded to fill the entire LCD screen when a -mode with less than full resolution is used. Note that the current -video expansion status cannot be determined through this feature. - -Note that on many models (particularly those using Radeon graphics -chips) the X driver configures the video card in a way which prevents -Fn-F7 from working. This also disables the video output switching -features of this driver, as it uses the same ACPI methods as -Fn-F7. Video switching on the console should still work. - -ThinkLight control -- /proc/acpi/ibm/light ------------------------------------------- - -The current status of the ThinkLight can be found in this file. A few -models which do not make the status available will show it as -"unknown". The available commands are: - - echo on > /proc/acpi/ibm/light - echo off > /proc/acpi/ibm/light - -Docking / Undocking -- /proc/acpi/ibm/dock ------------------------------------------- - -Docking and undocking (e.g. with the X4 UltraBase) requires some -actions to be taken by the operating system to safely make or break -the electrical connections with the dock. - -The docking feature of this driver generates the following ACPI events: - - ibm/dock GDCK 00000003 00000001 -- eject request - ibm/dock GDCK 00000003 00000002 -- undocked - ibm/dock GDCK 00000000 00000003 -- docked - -NOTE: These events will only be generated if the laptop was docked -when originally booted. This is due to the current lack of support for -hot plugging of devices in the Linux ACPI framework. If the laptop was -booted while not in the dock, the following message is shown in the -logs: "ibm_acpi: dock device not present". No dock-related events are -generated but the dock and undock commands described below still -work. They can be executed manually or triggered by Fn key -combinations (see the example acpid configuration files included in -the driver tarball package available on the web site). - -When the eject request button on the dock is pressed, the first event -above is generated. The handler for this event should issue the -following command: - - echo undock > /proc/acpi/ibm/dock - -After the LED on the dock goes off, it is safe to eject the laptop. -Note: if you pressed this key by mistake, go ahead and eject the -laptop, then dock it back in. Otherwise, the dock may not function as -expected. - -When the laptop is docked, the third event above is generated. The -handler for this event should issue the following command to fully -enable the dock: - - echo dock > /proc/acpi/ibm/dock - -The contents of the /proc/acpi/ibm/dock file shows the current status -of the dock, as provided by the ACPI framework. - -The docking support in this driver does not take care of enabling or -disabling any other devices you may have attached to the dock. For -example, a CD drive plugged into the UltraBase needs to be disabled or -enabled separately. See the provided example acpid configuration files -for how this can be accomplished. - -There is no support yet for PCI devices that may be attached to a -docking station, e.g. in the ThinkPad Dock II. The driver currently -does not recognize, enable or disable such devices. This means that -the only docking stations currently supported are the X-series -UltraBase docks and "dumb" port replicators like the Mini Dock (the -latter don't need any ACPI support, actually). - -UltraBay Eject -- /proc/acpi/ibm/bay ------------------------------------- - -Inserting or ejecting an UltraBay device requires some actions to be -taken by the operating system to safely make or break the electrical -connections with the device. - -This feature generates the following ACPI events: - - ibm/bay MSTR 00000003 00000000 -- eject request - ibm/bay MSTR 00000001 00000000 -- eject lever inserted - -NOTE: These events will only be generated if the UltraBay was present -when the laptop was originally booted (on the X series, the UltraBay -is in the dock, so it may not be present if the laptop was undocked). -This is due to the current lack of support for hot plugging of devices -in the Linux ACPI framework. If the laptop was booted without the -UltraBay, the following message is shown in the logs: "ibm_acpi: bay -device not present". No bay-related events are generated but the eject -command described below still works. It can be executed manually or -triggered by a hot key combination. - -Sliding the eject lever generates the first event shown above. The -handler for this event should take whatever actions are necessary to -shut down the device in the UltraBay (e.g. call idectl), then issue -the following command: - - echo eject > /proc/acpi/ibm/bay - -After the LED on the UltraBay goes off, it is safe to pull out the -device. - -When the eject lever is inserted, the second event above is -generated. The handler for this event should take whatever actions are -necessary to enable the UltraBay device (e.g. call idectl). - -The contents of the /proc/acpi/ibm/bay file shows the current status -of the UltraBay, as provided by the ACPI framework. - -Experimental Features ---------------------- - -The following features are marked experimental because using them -involves guessing the correct values of some parameters. Guessing -incorrectly may have undesirable effects like crashing your -ThinkPad. USE THESE WITH CAUTION! To activate them, you'll need to -supply the experimental=1 parameter when loading the module. - -Experimental: CMOS control - /proc/acpi/ibm/cmos ------------------------------------------------- - -This feature is used internally by the ACPI firmware to control the -ThinkLight on most newer ThinkPad models. It appears that it can also -control LCD brightness, sounds volume and more, but only on some -models. - -The commands are non-negative integer numbers: - - echo 0 >/proc/acpi/ibm/cmos - echo 1 >/proc/acpi/ibm/cmos - echo 2 >/proc/acpi/ibm/cmos - ... - -The range of numbers which are used internally by various models is 0 -to 21, but it's possible that numbers outside this range have -interesting behavior. Here is the behavior on the X40 (tpb is the -ThinkPad Buttons utility): - - 0 - no effect but tpb reports "Volume down" - 1 - no effect but tpb reports "Volume up" - 2 - no effect but tpb reports "Mute on" - 3 - simulate pressing the "Access IBM" button - 4 - LCD brightness up - 5 - LCD brightness down - 11 - toggle screen expansion - 12 - ThinkLight on - 13 - ThinkLight off - 14 - no effect but tpb reports ThinkLight status change - -If you try this feature, please send me a report similar to the -above. On models which allow control of LCD brightness or sound -volume, I'd like to provide this functionality in an user-friendly -way, but first I need a way to identify the models which this is -possible. - -Experimental: LED control - /proc/acpi/ibm/LED ----------------------------------------------- - -Some of the LED indicators can be controlled through this feature. The -available commands are: - - echo on >/proc/acpi/ibm/led - echo off >/proc/acpi/ibm/led - echo blink >/proc/acpi/ibm/led - -The parameter is a non-negative integer. The range of LED -numbers used internally by various models is 0 to 7 but it's possible -that numbers outside this range are also valid. Here is the mapping on -the X40: - - 0 - power - 1 - battery (orange) - 2 - battery (green) - 3 - UltraBase - 4 - UltraBay - 7 - standby - -All of the above can be turned on and off and can be made to blink. - -If you try this feature, please send me a report similar to the -above. I'd like to provide this functionality in an user-friendly way, -but first I need to identify the which numbers correspond to which -LEDs on various models. - -Experimental: ACPI sounds - /proc/acpi/ibm/beep ------------------------------------------------ - -The BEEP method is used internally by the ACPI firmware to provide -audible alerts in various situtation. This feature allows the same -sounds to be triggered manually. - -The commands are non-negative integer numbers: - - echo 0 >/proc/acpi/ibm/beep - echo 1 >/proc/acpi/ibm/beep - echo 2 >/proc/acpi/ibm/beep - ... - -The range of numbers which are used internally by various models is 0 -to 17, but it's possible that numbers outside this range are also -valid. Here is the behavior on the X40: - - 2 - two beeps, pause, third beep - 3 - single beep - 4 - "unable" - 5 - single beep - 6 - "AC/DC" - 7 - high-pitched beep - 9 - three short beeps - 10 - very long beep - 12 - low-pitched beep - -(I've only been able to identify a couple of them). - -If you try this feature, please send me a report similar to the -above. I'd like to provide this functionality in an user-friendly way, -but first I need to identify the which numbers correspond to which -sounds on various models. - - -Multiple Command, Module Parameters ------------------------------------ - -Multiple commands can be written to the proc files in one shot by -separating them with commas, for example: - - echo enable,0xffff > /proc/acpi/ibm/hotkey - echo lcd_disable,crt_enable > /proc/acpi/ibm/video - -Commands can also be specified when loading the ibm_acpi module, for -example: - - modprobe ibm_acpi hotkey=enable,0xffff video=auto_disable - - -Example Configuration ---------------------- - -The ACPI support in the kernel is intended to be used in conjunction -with a user-space daemon, acpid.

Creating a kbuild file for an external module". - - -=== 2. How to build external modules - -kbuild offers functionality to build external modules, with the -prerequisite that there is a pre-built kernel available with full source. -A subset of the targets available when building the kernel is available -when building an external module. - ---- 2.1 Building external modules - - Use the following command to build an external module: - - make -C M=`pwd` - - For the running kernel use: - make -C /lib/modules/`uname -r`/build M=`pwd` - - For the above command to succeed the kernel must have been built with - modules enabled. - - To install the modules that were just built: - - make -C M=`pwd` modules_install - - More complex examples later, the above should get you going. - ---- 2.2 Available targets - - $KDIR refers to path to kernel source top-level directory - - make -C $KDIR M=`pwd` - Will build the module(s) located in current directory. - All output files will be located in the same directory - as the module source. - No attempts are made to update the kernel source, and it is - a precondition that a successful make has been executed - for the kernel. - - make -C $KDIR M=`pwd` modules - The modules target is implied when no target is given. - Same functionality as if no target was specified. - See description above. - - make -C $KDIR M=$PWD modules_install - Install the external module(s). - Installation default is in /lib/modules//extra, - but may be prefixed with INSTALL_MOD_PATH - see separate chater. - - make -C $KDIR M=$PWD clean - Remove all generated files for the module - the kernel - source directory is not moddified. - - make -C $KDIR M=`pwd` help - help will list the available target when building external - modules. - ---- 2.3 Available options: - - $KDIR refer to path to kernel src - - make -C $KDIR - Used to specify where to find the kernel source. - '$KDIR' represent the directory where the kernel source is. - Make will actually change directory to the specified directory - when executed but change back when finished. - - make -C $KDIR M=`pwd` - M= is used to tell kbuild that an external module is - being built. - The option given to M= is the directory where the external - module (kbuild file) is located. - When an external module is being built only a subset of the - usual targets are available. - - make -C $KDIR SUBDIRS=`pwd` - Same as M=. The SUBDIRS= syntax is kept for backwards - compatibility. - ---- 2.4 Preparing the kernel tree for module build - - To make sure the kernel contains the information required to - build external modules the target 'modules_prepare' must be used. - 'module_prepare' solely exists as a simple way to prepare - a kernel for building external modules. - Note: modules_prepare will not build Module.symvers even if - CONFIG_MODULEVERSIONING is set. - Therefore a full kernel build needs to be executed to make - module versioning work. - - -=== 3. Example commands - -This example shows the actual commands to be executed when building -an external module for the currently running kernel. -In the example below the distribution is supposed to use the -facility to locate output files for a kernel compile in a different -directory than the kernel source - but the examples will also work -when the source and the output files are mixed in the same directory. - -# Kernel source -/lib/modules//source -> /usr/src/linux- - -# Output from kernel compile -/lib/modules//build -> /usr/src/linux--up - -Change to the directory where the kbuild file is located and execute -the following commands to build the module: - - cd /home/user/src/module - make -C /usr/src/`uname -r`/source \ - O=/lib/modules/`uname-r`/build \ - M=`pwd` - -Then to install the module use the following command: - - make -C /usr/src/`uname -r`/source \ - O=/lib/modules/`uname-r`/build \ - M=`pwd` \ - modules_install - -If one looks closely you will see that this is the same commands as -listed before - with the directories spelled out. - -The above are rather long commands, and the following chapter -lists a few tricks to make it all easier. - - -=== 4. Creating a kbuild file for an external module - -kbuild is the build system for the kernel, and external modules -must use kbuild to stay compatible with changes in the build system -and to pick up the right flags to gcc etc. - -The kbuild file used as input shall follow the syntax described -in Documentation/kbuild/makefiles.txt. This chapter will introduce a few -more tricks to be used when dealing with external modules. - -In the following a Makefile will be created for a module with the -following files: - 8123_if.c - 8123_if.h - 8123_pci.c - 8123_bin.o_shipped <= Binary blob - ---- 4.1 Shared Makefile for module and kernel - - An external module always includes a wrapper Makefile supporting - building the module using 'make' with no arguments. - The Makefile provided will most likely include additional - functionality such as test targets etc. and this part shall - be filtered away from kbuild since it may impact kbuild if - name clashes occurs. - - Example 1: - --> filename: Makefile - ifneq ($(KERNELRELEASE),) - # kbuild part of makefile - obj-m := 8123.o - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - else - # Normal Makefile - - KERNELDIR := /lib/modules/`uname -r`/build - all:: - $(MAKE) -C $KERNELDIR M=`pwd` $@ - - # Module specific targets - genbin: - echo "X" > 8123_bini.o_shipped - - endif - - In example 1 the check for KERNELRELEASE is used to separate - the two parts of the Makefile. kbuild will only see the two - assignments whereas make will see everything except the two - kbuild assignments. - - In recent versions of the kernel, kbuild will look for a file named - Kbuild and as second option look for a file named Makefile. - Utilising the Kbuild file makes us split up the Makefile in example 1 - into two files as shown in example 2: - - Example 2: - --> filename: Kbuild - obj-m := 8123.o - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - --> filename: Makefile - KERNELDIR := /lib/modules/`uname -r`/build - all:: - $(MAKE) -C $KERNELDIR M=`pwd` $@ - - # Module specific targets - genbin: - echo "X" > 8123_bin_shipped - - - In example 2 we are down to two fairly simple files and for simple - files as used in this example the split is questionable. But some - external modules use Makefiles of several hundred lines and here it - really pays off to separate the kbuild part from the rest. - Example 3 shows a backward compatible version. - - Example 3: - --> filename: Kbuild - obj-m := 8123.o - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - --> filename: Makefile - ifneq ($(KERNELRELEASE),) - include Kbuild - else - # Normal Makefile - - KERNELDIR := /lib/modules/`uname -r`/build - all:: - $(MAKE) -C $KERNELDIR M=`pwd` $@ - - # Module specific targets - genbin: - echo "X" > 8123_bin_shipped - - endif - - The trick here is to include the Kbuild file from Makefile so - if an older version of kbuild picks up the Makefile the Kbuild - file will be included. - ---- 4.2 Binary blobs included in a module - - Some external modules needs to include a .o as a blob. kbuild - has support for this, but requires the blob file to be named - _shipped. In our example the blob is named - 8123_bin.o_shipped and when the kbuild rules kick in the file - 8123_bin.o is created as a simple copy off the 8213_bin.o_shipped file - with the _shipped part stripped of the filename. - This allows the 8123_bin.o filename to be used in the assignment to - the module. - - Example 4: - obj-m := 8123.o - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - In example 4 there is no distinction between the ordinary .c/.h files - and the binary file. But kbuild will pick up different rules to create - the .o file. - - -=== 5. Include files - -Include files are a necessity when a .c file uses something from another .c -files (not strictly in the sense of .c but if good programming practice is -used). Any module that consist of more than one .c file will have a .h file -for one of the .c files. -- If the .h file only describes a module internal interface then the .h file - shall be placed in the same directory as the .c files. -- If the .h files describe an interface used by other parts of the kernel - located in different directories, the .h files shall be located in - include/linux/ or other include/ directories as appropriate. - -One exception for this rule is larger subsystems that have their own directory -under include/ such as include/scsi. Another exception is arch-specific -.h files which are located under include/asm-$(ARCH)/*. - -External modules have a tendency to locate include files in a separate include/ -directory and therefore needs to deal with this in their kbuild file. - ---- 5.1 How to include files from the kernel include dir - - When a module needs to include a file from include/linux/ then one - just uses: - - #include - - kbuild will make sure to add options to gcc so the relevant - directories are searched. - Likewise for .h files placed in the same directory as the .c file. - - #include "8123_if.h" - - will do the job. - ---- 5.2 External modules using an include/ dir - - External modules often locate their .h files in a separate include/ - directory although this is not usual kernel style. When an external - module uses an include/ dir then kbuild needs to be told so. - The trick here is to use either EXTRA_CFLAGS (take effect for all .c - files) or CFLAGS_$F.o (take effect only for a single file). - - In our example if we move 8123_if.h to a subdirectory named include/ - the resulting Kbuild file would look like: - - --> filename: Kbuild - obj-m := 8123.o - - EXTRA_CFLAGS := -Iinclude - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - Note that in the assingment there is no space between -I and the path. - This is a kbuild limitation and no space must be present. - - -=== 6. Module installation - -Modules which are included in the kernel is installed in the directory: - - /lib/modules/$(KERNELRELEASE)/kernel - -External modules are installed in the directory: - - /lib/modules/$(KERNELRELEASE)/extra - ---- 6.1 INSTALL_MOD_PATH - - Above are the default directories, but as always some level of - customization is possible. One can prefix the path using the variable - INSTALL_MOD_PATH: - - $ make INSTALL_MOD_PATH=/frodo modules_install - => Install dir: /frodo/lib/modules/$(KERNELRELEASE)/kernel - - INSTALL_MOD_PATH may be set as an ordinary shell variable or as in the - example above be specified on the commandline when calling make. - INSTALL_MOD_PATH has effect both when installing modules included in - the kernel as well as when installing external modules. - ---- 6.2 INSTALL_MOD_DIR - - When installing external modules they are default installed in a - directory under /lib/modules/$(KERNELRELEASE)/extra, but one may wish - to locate modules for a specific functionality in a separate - directory. For this purpose one can use INSTALL_MOD_DIR to specify an - alternative name than 'extra'. - - $ make INSTALL_MOD_DIR=gandalf -C KERNELDIR \ - M=`pwd` modules_install - => Install dir: /lib/modules/$(KERNELRELEASE)/gandalf - - -=== 7. Module versioning - -Module versioning are enabled by the CONFIG_MODVERSIONS tag. - -Module versioning is used as a simple ABI consistency check. The Module -versioning creates a CRC value of the full prototype for an exported symbol and -when a module is loaded/used then the CRC values contained in the kernel are -compared with similar values in the module. If they are not equal then the -kernel refuses to load the module. - -During a kernel build a file named Module.symvers will be generated. This -file includes the symbol version of all symbols within the kernel. If the -Module.symvers file is saved from the last full kernel compile one does not -have to do a full kernel compile to build a module version's compatible module. - -=== 8. Tips & Tricks - ---- 8.1 Testing for CONFIG_FOO_BAR - - Modules often needs to check for certain CONFIG_ options to decide if - a specific feature shall be included in the module. When kbuild is used - this is done by referencing the CONFIG_ variable directly. - - #fs/ext2/Makefile - obj-$(CONFIG_EXT2_FS) += ext2.o - - ext2-y := balloc.o bitmap.o dir.o - ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o - - External modules have traditionally used grep to check for specific - CONFIG_ settings directly in .config. This usage is broken. - As introduced before external modules shall use kbuild when building - and therefore can use the same methods as in-kernel modules when testing - for CONFIG_ definitions. - +For now this is a raw copy from the old Documentation/kbuild/modules.txt, +which was removed in 2.6.0-test5. +The information herein is correct but not complete. + +Installing modules in a non-standard location +--------------------------------------------- +When the modules needs to be installed under another directory +the INSTALL_MOD_PATH can be used to prefix "/lib/modules" as seen +in the following example: + +make INSTALL_MOD_PATH=/frodo modules_install + +This will install the modules in the directory /frodo/lib/modules. +/frodo can be a NFS mounted filesystem on another machine, allowing +out-of-the-box support for installation on remote machines. + + +Compiling modules outside the official kernel +--------------------------------------------- + +Often modules are developed outside the official kernel. To keep up +with changes in the build system the most portable way to compile a +module outside the kernel is to use the kernel build system, +kbuild.

These can be created, updated and read by userspace, - and aren't intended for use by kernel services. - - (*) Each process subscribes to three keyrings: a thread-specific keyring, a - process-specific keyring, and a session-specific keyring. - - The thread-specific keyring is discarded from the child when any sort of - clone, fork, vfork or execve occurs. A new keyring is created only when - required. - - The process-specific keyring is replaced with an empty one in the child - on clone, fork, vfork unless CLONE_THREAD is supplied, in which case it - is shared. execve also discards the process's process keyring and creates - a new one. - - The session-specific keyring is persistent across clone, fork, vfork and - execve, even when the latter executes a set-UID or set-GID binary. A - process can, however, replace its current session keyring with a new one - by using PR_JOIN_SESSION_KEYRING. It is permitted to request an anonymous - new one, or to attempt to create or join one of a specific name. - - The ownership of the thread and process-specific keyrings changes when - the real UID and GID of the thread changes. - - (*) Each user ID resident in the system holds two special keyrings: a user - specific keyring and a default user session keyring. The default session - keyring is initialised with a link to the user-specific keyring. - - When a process changes its real UID, if it used to have no session key, it - will be subscribed to the default session key for the new UID. - - If a process attempts to access its session key when it doesn't have one, - it will be subscribed to the default for its current UID. - - (*) Each user has two quotas against which the keys they own are tracked. One - limits the total number of keys and keyrings, the other limits the total - amount of description and payload space that can be consumed. - - The user can view information on this and other statistics through procfs - files. - - Process-specific and thread-specific keyrings are not counted towards a - user's quota. - - If a system call that modifies a key or keyring in some way would put the - user over quota, the operation is refused and error EDQUOT is returned. - - (*) There's a system call interface by which userspace programs can create - and manipulate keys and keyrings. - - (*) There's a kernel interface by which services can register types and - search for keys. - - (*) There's a way for the a search done from the kernel to call back to - userspace to request a key that can't be found in a process's keyrings. - - (*) An optional filesystem is available through which the key database can be - viewed and manipulated. - - -====================== -KEY ACCESS PERMISSIONS -====================== - -Keys have an owner user ID, a group access ID, and a permissions mask. The -mask has up to eight bits each for user, group and other access. Only five of -each set of eight bits are defined.

Further attempts to - use the key will be met with error EKEYREVOKED, and the key will no longer - be findable. - - - (*) Change the ownership of a key: - - long keyctl(KEYCTL_CHOWN, key_serial_t key, uid_t uid, gid_t gid); - - This function permits a key's owner and group ID to be changed. Either - one of uid or gid can be set to -1 to suppress that change. - - Only the superuser can change a key's owner to something other than the - key's current owner. Similarly, only the superuser can change a key's - group ID to something other than the calling process's group ID or one of - its group list members. - - - (*) Change the permissions mask on a key: - - long keyctl(KEYCTL_SETPERM, key_serial_t key, key_perm_t perm); - - This function permits the owner of a key or the superuser to change the - permissions mask on a key. - - Only bits the available bits are permitted; if any other bits are set, - error EINVAL will be returned. - - - (*) Describe a key: - - long keyctl(KEYCTL_DESCRIBE, key_serial_t key, char *buffer, - size_t buflen); - - This function returns a summary of the key's attributes (but not its - payload data) as a string in the buffer provided. - - Unless there's an error, it always returns the amount of data it could - produce, even if that's too big for the buffer, but it won't copy more - than requested to userspace. If the buffer pointer is NULL then no copy - will take place. - - A process must have view permission on the key for this function to be - successful. - - If successful, a string is placed in the buffer in the following format: - - ;;;; - - Where type and description are strings, uid and gid are decimal, and perm - is hexadecimal. A NUL character is included at the end of the string if - the buffer is sufficiently big. - - This can be parsed with - - sscanf(buffer, "%[^;];%d;%d;%o;%s", type, &uid, &gid, &mode, desc); - - - (*) Clear out a keyring: - - long keyctl(KEYCTL_CLEAR, key_serial_t keyring); - - This function clears the list of keys attached to a keyring. The calling - process must have write permission on the keyring, and it must be a - keyring (or else error ENOTDIR will result). - - - (*) Link a key into a keyring: - - long keyctl(KEYCTL_LINK, key_serial_t keyring, key_serial_t key); - - This function creates a link from the keyring to the key. The process - must have write permission on the keyring and must have link permission - on the key. - - Should the keyring not be a keyring, error ENOTDIR will result; and if - the keyring is full, error ENFILE will result. - - The link procedure checks the nesting of the keyrings, returning ELOOP if - it appears to deep or EDEADLK if the link would introduce a cycle. - - - (*) Unlink a key or keyring from another keyring: - - long keyctl(KEYCTL_UNLINK, key_serial_t keyring, key_serial_t key); - - This function looks through the keyring for the first link to the - specified key, and removes it if found. Subsequent links to that key are - ignored. The process must have write permission on the keyring. - - If the keyring is not a keyring, error ENOTDIR will result; and if the - key is not present, error ENOENT will be the result. - - - (*) Search a keyring tree for a key: - - key_serial_t keyctl(KEYCTL_SEARCH, key_serial_t keyring, - const char *type, const char *description, - key_serial_t dest_keyring); - - This searches the keyring tree headed by the specified keyring until a - key is found that matches the type and description criteria. Each keyring - is checked for keys before recursion into its children occurs. - - The process must have search permission on the top level keyring, or else - error EACCES will result. Only keyrings that the process has search - permission on will be recursed into, and only keys and keyrings for which - a process has search permission can be matched. If the specified keyring - is not a keyring, ENOTDIR will result. - - If the search succeeds, the function will attempt to link the found key - into the destination keyring if one is supplied (non-zero ID). All the - constraints applicable to KEYCTL_LINK apply in this case too. - - Error ENOKEY, EKEYREVOKED or EKEYEXPIRED will be returned if the search - fails. On success, the resulting key ID will be returned. - - - (*) Read the payload data from a key: - - key_serial_t keyctl(KEYCTL_READ, key_serial_t keyring, char *buffer, - size_t buflen); - - This function attempts to read the payload data from the specified key - into the buffer. The process must have read permission on the key to - succeed. - - The returned data will be processed for presentation by the key type. For - instance, a keyring will return an array of key_serial_t entries - representing the IDs of all the keys to which it is subscribed. The user - defined key type will return its data as is. If a key type does not - implement this function, error EOPNOTSUPP will result. - - As much of the data as can be fitted into the buffer will be copied to - userspace if the buffer pointer is not NULL. - - On a successful return, the function will always return the amount of - data available rather than the amount copied. - - - (*) Instantiate a partially constructed key. - - key_serial_t keyctl(KEYCTL_INSTANTIATE, key_serial_t key, - const void *payload, size_t plen, - key_serial_t keyring); - - If the kernel calls back to userspace to complete the instantiation of a - key, userspace should use this call to supply data for the key before the - invoked process returns, or else the key will be marked negative - automatically. - - The process must have write access on the key to be able to instantiate - it, and the key must be uninstantiated. - - If a keyring is specified (non-zero), the key will also be linked into - that keyring, however all the constraints applying in KEYCTL_LINK apply - in this case too. - - The payload and plen arguments describe the payload data as for add_key(). - - - (*) Negatively instantiate a partially constructed key. - - key_serial_t keyctl(KEYCTL_NEGATE, key_serial_t key, - unsigned timeout, key_serial_t keyring); - - If the kernel calls back to userspace to complete the instantiation of a - key, userspace should use this call mark the key as negative before the - invoked process returns if it is unable to fulfil the request. - - The process must have write access on the key to be able to instantiate - it, and the key must be uninstantiated. - - If a keyring is specified (non-zero), the key will also be linked into - that keyring, however all the constraints applying in KEYCTL_LINK apply - in this case too. - - -=============== -KERNEL SERVICES -=============== - -The kernel services for key managment are fairly simple to deal with. They can -be broken down into two areas: keys and key types. - -Dealing with keys is fairly straightforward. Firstly, the kernel service -registers its type, then it searches for a key of that type. It should retain -the key as long as it has need of it, and then it should release it. For a -filesystem or device file, a search would probably be performed during the -open call, and the key released upon close. How to deal with conflicting keys -due to two different users opening the same file is left to the filesystem -author to solve. - -When accessing a key's payload data, the key->lock should be at least read -locked, or else the data may be changed by update during the access. - -(*) To search for a key, call: - - struct key *request_key(const struct key_type *type, - const char *description, - const char *callout_string); - - This is used to request a key or keyring with a description that matches - the description specified according to the key type's match function. This - permits approximate matching to occur. If callout_string is not NULL, then - /sbin/request-key will be invoked in an attempt to obtain the key from - userspace. In that case, callout_string will be passed as an argument to - the program. - - Should the function fail error ENOKEY, EKEYEXPIRED or EKEYREVOKED will be - returned. - - -(*) When it is no longer required, the key should be released using: - - void key_put(struct key *key); - - This can be called from interrupt context. If CONFIG_KEYS is not set then - the argument will not be parsed. - - -(*) Extra references can be made to a key by calling the following function: - - struct key *key_get(struct key *key); - - These need to be disposed of by calling key_put() when they've been - finished with. The key pointer passed in will be returned. If the pointer - is NULL or CONFIG_KEYS is not set then the key will not be dereferenced and - no increment will take place. - - -(*) A key's serial number can be obtained by calling: - - key_serial_t key_serial(struct key *key); - - If key is NULL or if CONFIG_KEYS is not set then 0 will be returned (in the - latter case without parsing the argument). - - -(*) If a keyring was found in the search, this can be further searched by: - - struct key *keyring_search(struct key *keyring, - const struct key_type *type, - const char *description) - - This searches the keyring tree specified for a matching key. Error ENOKEY - is returned upon failure. If successful, the returned key will need to be - released. - - -(*) To check the validity of a key, this function can be called: - - int validate_key(struct key *key); - - This checks that the key in question hasn't expired or and hasn't been - revoked. Should the key be invalid, error EKEYEXPIRED or EKEYREVOKED will - be returned. If the key is NULL or if CONFIG_KEYS is not set then 0 will be - returned (in the latter case without parsing the argument). - - -(*) To register a key type, the following function should be called: - - int register_key_type(struct key_type *type); - - This will return error EEXIST if a type of the same name is already - present. - - -(*) To unregister a key type, call: - - void unregister_key_type(struct key_type *type); - - -=================== -DEFINING A KEY TYPE -=================== - -A kernel service may want to define its own key type. For instance, an AFS -filesystem might want to define a Kerberos 5 ticket key type. To do this, it -author fills in a struct key_type and registers it with the system. - -The structure has a number of fields, some of which are mandatory: - - (*) const char *name - - The name of the key type. This is used to translate a key type name - supplied by userspace into a pointer to the structure. - - - (*) size_t def_datalen - - This is optional - it supplies the default payload data length as - contributed to the quota. If the key type's payload is always or almost - always the same size, then this is a more efficient way to do things. - - The data length (and quota) on a particular key can always be changed - during instantiation or update by calling: - - int key_payload_reserve(struct key *key, size_t datalen); - - With the revised data length. Error EDQUOT will be returned if this is - not viable. - - - (*) int (*instantiate)(struct key *key, const void *data, size_t datalen); - - This method is called to attach a payload to a key during - construction. The payload attached need not bear any relation to the data - passed to this function. - - If the amount of data attached to the key differs from the size in - keytype->def_datalen, then key_payload_reserve() should be called. - - - (*) int (*duplicate)(struct key *key, const struct key *source); - - If this type of key can be duplicated, then this method should be - provided. It is called to copy the payload attached to the source into - the new key. The data length on the new key will have been updated and - the quota adjusted already. - - The source key will be locked against change on the source->sem, so it is - safe to sleep here. - - - (*) int (*update)(struct key *key, const void *data, size_t datalen); - - If this type of key can be updated, then this method should be - provided. It is called to update a key's payload from the blob of data - provided. - - key_payload_reserve() should be called if the data length might change - before any changes are actually made. Note that if this succeeds, the - type is committed to changing the key because it's already been altered, - so all memory allocation must be done first. - - The key will be locked against other changers on key->sem, so it is safe - to sleep here. - - key_payload_reserve() should be called with the key->lock write locked, - and the changes to the key's attached payload should be made before the - key is locked. - - - (*) int (*match)(const struct key *key, const void *desc); - - This method is called to match a key against a description. It should - return non-zero if the two match, zero if they don't. - - - (*) void (*destroy)(struct key *key); - - This method is optional. It is called to discard the payload data on a - key when it is being destroyed. - - - (*) void (*describe)(const struct key *key, struct seq_file *p); - - This method is optional. It is called during /proc/keys reading to - summarise a key in text form. - - - (*) long (*read)(const struct key *key, char __user *buffer, size_t buflen); - - This method is optional. It is called by KEYCTL_READ to translate the - key's payload into something a blob of data for userspace to deal - with.

A receive descriptor is a data - structure that describes a receive buffer and its attributes to the network - controller. The data in the descriptor is used by the controller to write - data from the controller to host memory. In the 3.0.x driver the valid - range for this parameter is 64-256. The default value is 64. This parameter - can be changed using the command - - ethtool -G eth? rx n, where n is the number of desired rx descriptors. - -Tx Descriptors: Number of transmit descriptors. A transmit descriptor is a - data structure that describes a transmit buffer and its attributes to the - network controller. The data in the descriptor is used by the controller to - read data from the host memory to the controller. In the 3.0.x driver the - valid range for this parameter is 64-256. The default value is 64. This - parameter can be changed using the command - - ethtool -G eth? tx n, where n is the number of desired tx descriptors. - -Speed/Duplex: The driver auto-negotiates the link speed and duplex settings by - default. Ethtool can be used as follows to force speed/duplex. - - ethtool -s eth? autoneg off speed {10|100} duplex {full|half} - - NOTE: setting the speed/duplex to incorrect values will cause the link to - fail. - -Event Log Message Level: The driver uses the message level flag to log events - to syslog. The message level can be set at driver load time. It can also be - set using the command - - ethtool -s eth? msglvl n - -Additional Configurations -========================= - - Configuring the Driver on Different Distributions - ------------------------------------------------- - - Configuring a network driver to load properly when the system is started is - distribution dependent. Typically, the configuration process involves adding - an alias line to /etc/modules.conf as well as editing other system startup - scripts and/or configuration files. Many popular Linux distributions ship - with tools to make these changes for you. To learn the proper way to - configure a network device for your system, refer to your distribution - documentation. If during this process you are asked for the driver or module - name, the name for the Linux Base Driver for the Intel PRO/100 Family of - Adapters is e100. - - As an example, if you install the e100 driver for two PRO/100 adapters - (eth0 and eth1), add the following to modules.conf: - - alias eth0 e100 - alias eth1 e100 - - Viewing Link Messages - --------------------- - In order to see link messages and other Intel driver information on your - console, you must set the dmesg level up to six. This can be done by - entering the following on the command line before loading the e100 driver: - - dmesg -n 8 - - If you wish to see all messages issued by the driver, including debug - messages, set the dmesg level to eight. - - NOTE: This setting is not saved across reboots. - - Ethtool - ------- - - The driver utilizes the ethtool interface for driver configuration and - diagnostics, as well as displaying statistical information. Ethtool - version 1.6 or later is required for this functionality. - - The latest release of ethtool can be found at: - http://sf.net/projects/gkernel. - - After ethtool is installed, ethtool-copy.h must be copied and renamed to - ethtool.h in your kernel source tree at /include/linux. - Backup the original ethtool.h as needed before copying. The driver then - must be recompiled in order to take advantage of the latest ethtool - features. - - NOTE: This driver uses mii support from the kernel. As a result, when - there is no link, ethtool will report speed/duplex to be 10/half. - - NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support - for a more complete ethtool feature set can be enabled by upgrading - ethtool to ethtool-1.8.1. - - Enabling Wake on LAN* (WoL) - --------------------------- - WoL is provided through the Ethtool* utility. Ethtool is included with Red - Hat* 8.0. For other Linux distributions, download and install Ethtool from - the following website: http://sourceforge.net/projects/gkernel. - - For instructions on enabling WoL with Ethtool, refer to the Ethtool man - page. - - WoL will be enabled on the system during the next shut down or reboot. For - this driver version, in order to enable WoL, the e100 driver must be - loaded when shutting down or rebooting the system. - - NAPI - ---- - - NAPI (Rx polling mode) is supported in the e100 driver. NAPI is enabled - or disabled based on the configuration of the kernel. - - See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
