/*
* This is the /proc/ide/ filesystem implementation.
*
- * The major reason this exists is to provide sufficient access
- * to driver and config data, such that user-mode programs can
- * be developed to handle chipset tuning for most PCI interfaces.
- * This should provide better utilities, and less kernel bloat.
- *
- * The entire pci config space for a PCI interface chipset can be
- * retrieved by just reading it. e.g. "cat /proc/ide3/config"
- *
- * To modify registers *safely*, do something like:
- * echo "P40:88" >/proc/ide/ide3/config
- * That expression writes 0x88 to pci config register 0x40
- * on the chip which controls ide3. Multiple tuples can be issued,
- * and the writes will be completed as an atomic set:
- * echo "P40:88 P41:35 P42:00 P43:00" >/proc/ide/ide3/config
- *
- * All numbers must be specified using pairs of ascii hex digits.
- * It is important to note that these writes will be performed
- * after waiting for the IDE controller (both interfaces)
- * to be completely idle, to ensure no corruption of I/O in progress.
- *
- * Non-PCI registers can also be written, using "R" in place of "P"
- * in the above examples. The size of the port transfer is determined
- * by the number of pairs of hex digits given for the data. If a two
- * digit value is given, the write will be a byte operation; if four
- * digits are used, the write will be performed as a 16-bit operation;
- * and if eight digits are specified, a 32-bit "dword" write will be
- * performed. Odd numbers of digits are not permitted.
- *
- * If there is an error *anywhere* in the string of registers/data
- * then *none* of the writes will be performed.
- *
* Drive/Driver settings can be retrieved by reading the drive's
* "settings" files. e.g. "cat /proc/ide0/hda/settings"
* To write a new value "val" into a specific setting "name", use:
* returned data as 256 16-bit words. The "hdparm" utility will
* be updated someday soon to use this mechanism.
*
- * Feel free to develop and distribute fancy GUI configuration
- * utilities for your favorite PCI chipsets. I'll be working on
- * one for the Promise 20246 someday soon. -ml
