-The short story
----------------
+Installation
+------------
To use laptop mode, you don't need to set any kernel configuration options
-or anything. You simply need to run the laptop_mode control script (which
-is included in this document) as follows:
-
-# laptop_mode start
+or anything. Simply install all the files included in this document, and
+laptop mode will automatically be started when you're on battery. For
+your convenience, a tarball containing an installer can be downloaded at:
-Then set your harddisk spindown time to a relatively low value with hdparm:
+http://www.xs4all.nl/~bsamwel/laptop_mode/tools
-hdparm -S 4 /dev/hda
+To configure laptop mode, you need to edit the configuration file, which is
+located in /etc/default/laptop-mode on Debian-based systems, or in
+/etc/sysconfig/laptop-mode on other systems.
-The value -S 4 means 20 seconds idle time before spindown. Your harddisk will
-now only spin up when a disk cache miss occurs, or at least once every 10
-minutes to write back any pending changes.
-
-To stop laptop_mode, run "laptop_mode stop".
+Unfortunately, automatic enabling of laptop mode does not work for
+laptops that don't have ACPI. On those laptops, you need to start laptop
+mode manually. To start laptop mode, run "laptop_mode start", and to
+stop it, run "laptop_mode stop". (Note: The laptop mode tools package now
+has experimental support for APM, you might want to try that first.)
Caveats
-------
-* The downside of laptop mode is that you have a chance of losing up
- to 10 minutes of work. If you cannot afford this, don't use it! It's
- wise to turn OFF laptop mode when you're almost out of battery --
- although this will make the battery run out faster, at least you'll
- lose less work when it actually runs out. I'm still looking for someone
- to submit instructions on how to turn off laptop mode when battery is low,
- e.g., using ACPI events. I don't have a laptop myself, so if you do and
- you care to contribute such instructions, please do.
+* The downside of laptop mode is that you have a chance of losing up to 10
+ minutes of work. If you cannot afford this, don't use it! The supplied ACPI
+ scripts automatically turn off laptop mode when the battery almost runs out,
+ so that you won't lose any data at the end of your battery life.
* Most desktop hard drives have a very limited lifetime measured in spindown
cycles, typically about 50.000 times (it's usually listed on the spec sheet).
* If you have your filesystems listed as type "auto" in fstab, like I did, then
the control script will not recognize them as filesystems that need remounting.
+ You must list the filesystems with their true type instead.
* It has been reported that some versions of the mutt mail client use file access
times to determine whether a folder contains new mail. If you use mutt and
- experience this, you must disable the noatime remounting in the control script
- by setting DO_REMOUNT_NOATIME=0.

-The details
+The Details
-----------
-Laptop-mode is controlled by the flag /proc/sys/vm/laptop_mode. This flag is
+Laptop mode is controlled by the knob /proc/sys/vm/laptop_mode. This knob is
present for all kernels that have the laptop mode patch, regardless of any
-configuration options. When the flag is set, any physical disk read operation
-(that might have caused the hard disk to spin up) causes Linux to flush all dirty
-blocks. The result of this is that after a disk has spun down, it will not be spun
-up anymore to write dirty blocks, because those blocks had already been written
-immediately after the most recent read operation.
+configuration options. When the knob is set, any physical disk I/O (that might
+have caused the hard disk to spin up) causes Linux to flush all dirty blocks. The
+result of this is that after a disk has spun down, it will not be spun up
+anymore to write dirty blocks, because those blocks had already been written
+immediately after the most recent read operation. The value of the laptop_mode
+knob determines the time between the occurrence of disk I/O and when the flush
+is triggered. A sensible value for the knob is 5 seconds. Setting the knob to
+0 disables laptop mode.
To increase the effectiveness of the laptop_mode strategy, the laptop_mode
control script increases dirty_expire_centisecs and dirty_writeback_centisecs in
all block dirtyings done to files. This makes it possible to debug why a disk
needs to spin up, and to increase battery life even more. The output of
block_dump is written to the kernel output, and it can be retrieved using
-"dmesg". When you use block_dump, you may want to turn off klogd, otherwise
+"dmesg". When you use block_dump and your kernel logging level also includes
+kernel debugging messages, you probably want to turn off klogd, otherwise
the output of block_dump will be logged, causing disk activity that is not
normally there.
-If 10 minutes is too much or too little downtime for you, you can configure
-this downtime as follows. In the control script, set the MAX_AGE value to the
-maximum number of seconds of disk downtime that you would like. You should
-then set your filesystem's commit interval to the same value. The dirty ratio
-is also configurable from the control script.
-If you don't like the idea of the control script remounting your filesystems
-for you, you can change DO_REMOUNTS to 0 in the script.
+Configuration
+-------------
+
+The laptop mode configuration file is located in /etc/default/laptop-mode on
+Debian-based systems, or in /etc/sysconfig/laptop-mode on other systems. It
+contains the following options:
+
+MAX_AGE:
+
+Maximum time, in seconds, of hard drive spindown time that you are
+confortable with. Worst case, it's possible that you could lose this
+amount of work if your battery fails while you're in laptop mode.
+
+MINIMUM_BATTERY_MINUTES:
+
+Automatically disable laptop mode if the remaining number of minutes of
+battery power is less than this value. Default is 10 minutes.
+
+AC_HD/BATT_HD:
+
+The idle timeout that should be set on your hard drive when laptop mode
+is active (BATT_HD) and when it is not active (AC_HD). The defaults are
+20 seconds (value 4) for BATT_HD and 2 hours (value 244) for AC_HD. The
+possible values are those listed in the manual page for "hdparm" for the
+"-S" option.
+
+HD:
+
+The devices for which the spindown timeout should be adjusted by laptop mode.
+Default is /dev/hda. If you specify multiple devices, separate them by a space.
+
+READAHEAD:
+
+Disk readahead, in 512-byte sectors, while laptop mode is active. A large
+readahead can prevent disk accesses for things like executable pages (which are
+loaded on demand while the application executes) and sequentially accessed data
+(MP3s).
+
+DO_REMOUNTS:
+
+The control script automatically remounts any mounted journaled filesystems
+with approriate commit interval options. When this option is set to 0, this
+feature is disabled.
+
+DO_REMOUNT_NOATIME:
+
+When remounting, should the filesystems be remounted with the noatime option?
+Normally, this is set to "1" (enabled), but there may be programs that require
+access time recording.
+
+DIRTY_RATIO:
-Thanks to Kiko Piris, the control script can be used to enable laptop mode on
-both the Linux 2.4 and 2.6 series.
+The percentage of memory that is allowed to contain "dirty" or unsaved data
+before a writeback is forced, while laptop mode is active. Corresponds to
+the /proc/sys/vm/dirty_ratio sysctl.
+
+DIRTY_BACKGROUND_RATIO:
+
+The percentage of memory that is allowed to contain "dirty" or unsaved data
+after a forced writeback is done due to an exceeding of DIRTY_RATIO. Set
+this nice and low. This corresponds to the /proc/sys/vm/dirty_background_ratio
+sysctl.
+
+Note that the behaviour of dirty_background_ratio is quite different
+when laptop mode is active and when it isn't. When laptop mode is inactive,
+dirty_background_ratio is the threshold percentage at which background writeouts
+start taking place. When laptop mode is active, however, background writeouts
+are disabled, and the dirty_background_ratio only determines how much writeback
+is done when dirty_ratio is reached.
+
+DO_CPU:
+
+Enable CPU frequency scaling when in laptop mode. (Requires CPUFreq to be setup.
+See Documentation/cpu-freq/user-guide.txt for more info. Disabled by default.)
+
+CPU_MAXFREQ:
+
+When on battery, what is the maximum CPU speed that the system should use? Legal
+values are "slowest" for the slowest speed that your CPU is able to operate at,
+or a value listed in /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies.
Tips & Tricks
-------------
* Bartek Kania reports getting up to 50 minutes of extra battery life (on top
- of his regular 3 to 3.5 hours) using very aggressive power management (hdparm
- -B1) and a spindown time of 5 seconds (hdparm -S1).

- to 8MB (hdparm -a 16384). Effectively, the disk will read a complete MP3 at

Kania.)
this on powerbooks too. I hope that this is a piece of information that
might be useful to the Laptop Mode patch or it's users."
-* One thing which will cause disks to spin up is not-present application
- and dynamic library text pages. The kernel will load program text off disk
- on-demand, so each time you invoke an application feature for the first
- time, the kernel needs to spin the disk up to go and fetch that part of the
- application.
-
- So it is useful to increase the disk readahead parameter greatly, so that
- the kernel will pull all of the executable's pages into memory on the first
- pagefault.
-
- The supplied script does this.
-
* In syslog.conf, you can prefix entries with a dash ``-'' to omit syncing the
file after every logging. When you're using laptop-mode and your disk doesn't
spin down, this is a likely culprit.
(http://noflushd.sourceforge.net/), it seems that noflushd prevents laptop-mode
from doing its thing.
+* If you're worried about your data, you might want to consider using a USB
+ memory stick or something like that as a "working area". (Be aware though
+ that flash memory can only handle a limited number of writes, and overuse
+ may wear out your memory stick pretty quickly. Do _not_ use journalling
+ filesystems on flash memory sticks.)

toward merging suspend2 into the mainline kernel.

+Q: Kernel thread must voluntarily freeze itself (call 'refrigerator'). But
+I found some kernel threads don't do it, and they don't freeze, and
+so the system can't sleep. Is this a known behavior?
+
+A: All such kernel threads need to be fixed, one by one. Select place
+where it is safe to be frozen (no kernel semaphores should be held at
+that point and it must be safe to sleep there), and add:
+
+ if (current->flags & PF_FREEZE)
+ refrigerator(PF_FREEZE);
+
+Q: What is the difference between between "platform", "shutdown" and
+"firmware" in /sys/power/disk?
+
+A:
+
+shutdown: save state in linux, then tell bios to powerdown
+
+platform: save state in linux, then tell bios to powerdown and blink
+ "suspended led"
+
+firmware: tell bios to save state itself [needs BIOS-specific suspend
+ partition, and has very little to do with swsusp]
+
+"platform" is actually right thing to do, but "shutdown" is most
+reliable.

+ AES cipher algorithms (FIPS-197). AES uses the Rijndael
+ algorithm.
+
+ Rijndael appears to be consistently a very good performer in
+ both hardware and software across a wide range of computing
+ environments regardless of its use in feedback or non-feedback
+ modes. Its key setup time is excellent, and its key agility is
+ good. Rijndael's very low memory requirements make it very well
+ suited for restricted-space environments, in which it also
+ demonstrates excellent performance. Rijndael's operations are
+ among the easiest to defend against power and timing attacks.
+
+ The AES specifies three key sizes: 128, 192 and 256 bits
+
+ See http://csrc.nist.gov/encryption/aes/ for more information.

- * Gianfar Ethernet Driver
- * Driver for FEC on MPC8540 and TSEC on MPC8540/MPC8560

- * Gianfar: AKA Lambda Draconis, "Dragon"
- * RA 11 31 24.2
- * Dec +69 19 52
- * V 3.84
- * B-V +1.62
- *
- * Theory of operation
- * This driver is designed for the Triple-speed Ethernet
- * controllers on the Freescale 8540/8560 integrated processors,
- * as well as the Fast Ethernet Controller on the 8540.
- *
- * The driver is initialized through OCP. Structures which
- * define the configuration needed by the board are defined in a
- * board structure in arch/ppc/platforms (though I do not
- * discount the possibility that other architectures could one
- * day be supported. One assumption the driver currently makes
- * is that the PHY is configured in such a way to advertise all
- * capabilities. This is a sensible default, and on certain
- * PHYs, changing this default encounters substantial errata
- * issues. Future versions may remove this requirement, but for
- * now, it is best for the firmware to ensure this is the case.
- *
- * The Gianfar Ethernet Controller uses a ring of buffer
- * descriptors. The beginning is indicated by a register
- * pointing to the physical address of the start of the ring.
- * The end is determined by a "wrap" bit being set in the
- * last descriptor of the ring.
- *
- * When a packet is received, the RXF bit in the
- * IEVENT register is set, triggering an interrupt when the
- * corresponding bit in the IMASK register is also set (if
- * interrupt coalescing is active, then the interrupt may not
- * happen immediately, but will wait until either a set number
- * of frames or amount of time have passed.). In NAPI, the
- * interrupt handler will signal there is work to be done, and
- * exit. Without NAPI, the packet(s) will be handled
- * immediately. Both methods will start at the last known empty
- * descriptor, and process every subsequent descriptor until there
- * are none left with data (NAPI will stop after a set number of
- * packets to give time to other tasks, but will eventually
- * process all the packets). The data arrives inside a
- * pre-allocated skb, and so after the skb is passed up to the
- * stack, a new skb must be allocated, and the address field in
- * the buffer descriptor must be updated to indicate this new
- * skb.
- *
- * When the kernel requests that a packet be transmitted, the
- * driver starts where it left off last time, and points the
- * descriptor at the buffer which was passed in. The driver
- * then informs the DMA engine that there are packets ready to
- * be transmitted. Once the controller is finished transmitting
- * the packet, an interrupt may be triggered (under the same
- * conditions as for reception, but depending on the TXF bit).
- * The driver then cleans up the buffer.

- This replaces the current existing IRQ-based index interrupt scheme
- with the vector-base index scheme. The advantages of vector base
- over IRQ base are listed below:
- 1) Support MSI implementation.
- 2) Support future IOxAPIC hotplug
-
- Note that this allows the device drivers to enable MSI, Message
- Signaled Interrupt, on all MSI capable device functions detected.
- Message Signal Interrupt enables an MSI-capable hardware device to
- send an inbound Memory Write on its PCI bus instead of asserting
- IRQ signal on device IRQ pin.
+ This allows device drivers to enable MSI (Message Signaled
+ Interrupts). Message Signaled Interrupts enable a device to
+ generate an interrupt using an inbound Memory Write on its
+ PCI bus instead of asserting a device IRQ pin.
If you don't know what to do here, say N.

- * drivers/serial/mpsc/mpsc.c
- *
- * Generic driver for the MPSC (UART mode) on Marvell parts (e.g., GT64240,
- * GT64260, MV64340, MV64360, GT96100, ... ).
- *
- * Author: Mark A. Greer <mgreer@mvista.com>
- *
- * Based on an old MPSC driver that was in the linuxppc tree. It appears to
- * have been created by Chris Zankel (formerly of MontaVista) but there
- * is no proper Copyright so I'm not sure. Parts were, apparently, also
- * taken from PPCBoot (now U-Boot). Also based on drivers/serial/8250.c
- * by Russell King.

-/*
- * The MPSC interface is much like a typical network controller's interface.
- * That is, you set up separate rings of descriptors for transmitting and
- * receiving data. There is also a pool of buffers with (one buffer per
- * descriptor) that incoming data are dma'd into or outgoing data are dma'd
- * out of.
- *
- * The MPSC requires two other controllers to be able to work. The Baud Rate
- * Generator (BRG) provides a clock at programmable frequencies which determines
- * the baud rate. The Serial DMA Controller (SDMA) takes incoming data from the
- * MPSC and DMA's it into memory or DMA's outgoing data and passes it to the
- * MPSC. It is actually the SDMA interrupt that the driver uses to keep the
- * transmit and receive "engines" going (i.e., indicate data has been
- * transmitted or received).
- *
- * NOTES:
- *
- * 1) Some chips have an erratum where several regs cannot be
- * read. To work around that, we keep a local copy of those regs in
- * 'mpsc_port_info_t' and use the *_M macros when accessing those regs.
- *
- * 2) Some chips have an erratum where the chip will hang when the SDMA ctlr
- * accesses system mem in a cache coherent region. This *should* be a
- * show-stopper when coherency is turned on but it seems to work okay as
- * long as there are no snoop hits. Therefore, there are explicit cache
- * management macros in addition to the dma_* calls--the dma_* calls don't
- * do cache mgmt on coherent systems--to manage the cache ensuring there
- * are no snoop hits.
- *
- * 3) AFAICT, hardware flow control isn't supported by the controller --MAG.

+Add config option to enable XATTR (extended attribute) support, mapping

+
+Version 1.21
+------------
+Add new mount parm to control whether mode check (vfs_permission) is done on
+the client. If Unix extensions are enabled and the uids on the client
+and server do not match, client permission checks are meaningless on
+server uids that do not exist on the client (this does not affect the
+normal ACL check which occurs on the server). Fix default uid
+on mknod to match create and mkdir. Add optional mount parm to allow
+override of the default uid behavior (in which the server sets the uid

1) Download the kernel (e.g. from http://www.kernel.org or from bitkeeper
at bk://linux.bkbits.net/linux-2.5) and change directory into the top
of the kernel directory tree (e.g. /usr/src/linux-2.5.73)
similar files reside (usually /sbin). Although the helper software is not
required, mount.cifs is recommended. Eventually the Samba 3.0 utility program
"net" may also be helpful since it may someday provide easier mount syntax for

+users who are used to Windows e.g. net use <mount point> <UNC name or cifs URL>
Note that running the Winbind pam/nss module (logon service) on all of your
Linux clients is useful in mapping Uids and Gids consistently across the
domain to the proper network user. The mount.cifs mount helper can be
gcc samba/source/client/mount.cifs.c -o mount.cifs
+Allowing User Mounts
+====================
+To permit users to mount and unmount over directories they own is possible
+with the cifs vfs. A way to enable such mounting is to mark the mount.cifs
+utility as suid (e.g. "chmod +s /sbin/mount/cifs). To enable users to
+umount shares they mount requires
+1) mount.cifs version 1.4 or later
+2) an entry for the share in /etc/fstab indicating that a user may
+unmount it e.g.
+//server/usersharename /mnt/username cifs user 0 0
+
Note that when the mount.cifs utility is run suid (allowing user mounts),
in order to reduce risks, the "nosuid" mount flag is passed in on mount to
disallow execution of an suid program mounted on the remote target.

("man smb.conf") on the Samba server system. Note that the cifs vfs,
unlike the smbfs vfs, does not read the smb.conf on the client system
(the few optional settings are passed in on mount via -o parameters instead).
Note that Samba 2.2.7 or later includes a fix that allows the CIFS VFS to delete
open files (required for strict POSIX compliance). Windows Servers already

files that are outside of the share) to a samba specific format on the server

or altered by a hostile router).
+Although mounting using format corresponding to the CIFS URL specification is
+not possible in mount.cifs yet, it is possible to use an alternate format
+for the server and sharename (which is somewhat similar to NFS style mount
+syntax) instead of the more widely used UNC format (i.e. \\server\share):
+ mount -t cifs tcp_name_of_server:share_name /mnt -o user=myname,pass=mypasswd
+
When using the mount helper mount.cifs, passwords may be specified via alternate
mechanisms, instead of specifying it after -o using the normal "pass=" syntax
on the command line:
mount helper will not prompt the user for a password
if guest is specified on the mount options. If no
password is specified a null password will be used.

The mount.cifs mount helper also accepts a few mount options before -o

+ depends on NET_SCHED
+ default NET_SCH_CLK_JIFFIES
+ help
+ Packet schedulers need a monotonic clock that increments at a static
+ rate. The kernel provides several suitable interfaces, each with
+ different properties:
+
+ - high resolution (us or better)
+ - fast to read (minimal locking, no i/o access)
+ - synchronized on all processors
+ - handles cpu clock frequency changes
+
+ but nothing provides all of the above.
+
+config NET_SCH_CLK_JIFFIES
+ bool "Timer interrupt"
+ help
+ Say Y here if you want to use the timer interrupt (jiffies) as clock
+ source. This clock source is fast, synchronized on all processors and
+ handles cpu clock frequency changes, but its resolution is too low
+ for accurate shaping except at very low speed.
+
+config NET_SCH_CLK_GETTIMEOFDAY
+ bool "gettimeofday"
+ help
+ Say Y here if you want to use gettimeofday as clock source. This clock
+ source has high resolution, is synchronized on all processors and
+ handles cpu clock frequency changes, but it is slow.
+
+ Choose this if you need a high resolution clock source but can't use
+ the CPU's cycle counter.
+
+config NET_SCH_CLK_CPU
+ bool "CPU cycle counter"
+ depends on X86_TSC || X86_64 || ALPHA || SPARC64 || PPC64 || IA64
+ help
+ Say Y here if you want to use the CPU's cycle counter as clock source.
+ This is a cheap and high resolution clock source, but on some
+ architectures it is not synchronized on all processors and doesn't
+ handle cpu clock frequency changes.
+
+ The useable cycle counters are:
+
+ x86/x86_64 - Timestamp Counter
+ alpha - Cycle Counter
+ sparc64 - %ticks register
+ ppc64 - Time base
+ ia64 - Interval Time Counter
+

+ * High-speed TUX logging architecture:
+ *
+ * All fast threads share a common log-ringbuffer. (default size 1MB)
+ * Log entries are binary and are padded to be cacheline aligned, this
+ * ensures that there is no cache-pingpong between fast threads.
+ *
+ * The logger thread writes out pending log entries within 1 second
+ * (buffer-cache writes data out within 5 seconds). The logger thread
+ * gets activated once we have more than 25% of the log ringbuffer
+ * filled - or the 1 second log timeout expires. Fast threads block
+ * if if more than 95% of the ringbuffer is filled and unblock only
+ * if used logbuffer space drops below 90%.
+ *
+ * This architecture guarantees that 1) logging is reliable (no
+ * log entry is ever lost), 2) timely (touches disk within 6 seconds),
+ * 3) in the log-contention case the saturation behavior is still
+ * write-clustered, but 4) if the logger thread can keep up then
+ * the coupling is completely asynchron and parallel.
+ *
+ * The binary log format gives us about 50% saved IO/memory bandwith
+ * and 50% less on-disk used log space than the traditional W3C ASCII
+ * format.
+ *
+ * (We might switch to raw IO though to write the logfile.)
