4. Compilation options
----------------------
There are a few additional options which can be set when compiling the
driver. Most people should not need to mess with any of these; they
are listed here simply for completeness. A compilation option can be
enabled by adding a line of the form `#define <option> 1' to the top
of ide-cd.c. All these options are disabled by default.
VERBOSE_IDE_CD_ERRORS
If this is set, ATAPI error codes will be translated into textual
descriptions. In addition, a dump is made of the command which
provoked the error. This is off by default to save the memory used
by the (somewhat long) table of error descriptions.
STANDARD_ATAPI
If this is set, the code needed to deal with certain drives which do
not properly implement the ATAPI spec will be disabled. If you know
your drive implements ATAPI properly, you can turn this on to get a
slightly smaller kernel.
NO_DOOR_LOCKING
If this is set, the driver will never attempt to lock the door of
the drive.
CDROM_NBLOCKS_BUFFER
This sets the size of the buffer to be used for a CDROMREADAUDIO
ioctl. The default is 8.
TEST
This currently enables an additional ioctl which enables a user-mode
program to execute an arbitrary packet command. See the source for
details. This should be left off unless you know what you're doing.

* CYPRESS CY82C693 chipset IDE controller
*
* The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards.
* Writing the driver was quite simple, since most of the job is
* done by the generic pci-ide support.
* The hard part was finding the CY82C693's datasheet on Cypress's
* web page :-(. But Altavista solved this problem :-).
*
*
* Notes:
* - I recently got a 16.8G IBM DTTA, so I was able to test it with
* a large and fast disk - the results look great, so I'd say the
* driver is working fine :-)
* hdparm -t reports 8.17 MB/sec at about 6% CPU usage for the DTTA
* - this is my first linux driver, so there's probably a lot of room
* for optimizations and bug fixing, so feel free to do it.
* - if using PIO mode it's a good idea to set the PIO mode and
* 32-bit I/O support (if possible), e.g. hdparm -p2 -c1 /dev/hda
* - I had some problems with my IBM DHEA with PIO modes < 2
* (lost interrupts) ?????
* - first tests with DMA look okay, they seem to work, but there is a
* problem with sound - the BusMaster IDE TimeOut should fixed this
*
* Ancient History:
* AMH@1999-08-24: v0.34 init_cy82c693_chip moved to pci_init_cy82c693
* ASK@1999-01-23: v0.33 made a few minor code clean ups
* removed DMA clock speed setting by default
* added boot message
* ASK@1998-11-01: v0.32 added support to set BusMaster IDE TimeOut
* added support to set DMA Controller Clock Speed
* ASK@1998-10-31: v0.31 fixed problem with setting to high DMA modes
* on some drives.
* ASK@1998-10-29: v0.3 added support to set DMA modes
* ASK@1998-10-28: v0.2 added support to set PIO modes
* ASK@1998-10-27: v0.1 first version - chipset detection

* Jan Harkes <jaharkes@cwi.nl>,
* Mark Lord <mlord@pobox.com>
* Some parts of code are from ali14xx.c and from rz1000.c.
*
* OPTi is trademark of OPTi, Octek is trademark of Octek.
*
* I used docs from OPTi databook, from ftp.opti.com, file 9123-0002.ps
* and disassembled/traced setupvic.exe (DOS program).
* It increases kernel code about 2 kB.
* I don't have this card no more, but I hope I can get some in case
* of needed development.
* My card is Octek PIDE 1.01 (on card) or OPTiViC (program).
* It has a place for a secondary connector in circuit, but nothing
* is there. Also BIOS says no address for
* secondary controller (see bellow in ide_init_opti621).
* I've only tested this on my system, which only has one disk.
* It's Western Digital WDAC2850, with PIO mode 3. The PCI bus
* is at 20 MHz (I have DX2/80, I tried PCI at 40, but I got random
* lockups). I tried the OCTEK double speed CD-ROM and
* it does not work! But I can't boot DOS also, so it's probably
* hardware fault. I have connected Conner 80MB, the Seagate 850MB (no
* problems) and Seagate 1GB (as slave, WD as master). My experiences
* with the third, 1GB drive: I got 3MB/s (hdparm), but sometimes
* it slows to about 100kB/s! I don't know why and I have
* not this drive now, so I can't try it again.
* I write this driver because I lost the paper ("manual") with
* settings of jumpers on the card and I have to boot Linux with
* Loadlin except LILO, cause I have to run the setupvic.exe program
* already or I get disk errors (my test: rpm -Vf
* /usr/X11R6/bin/XF86_SVGA - or any big file).
* Some numbers from hdparm -t /dev/hda:
* Timing buffer-cache reads: 32 MB in 3.02 seconds =10.60 MB/sec
* Timing buffered disk reads: 16 MB in 5.52 seconds = 2.90 MB/sec
* I have 4 Megs/s before, but I don't know why (maybe changes
* in hdparm test).
* After release of 0.1, I got some successful reports, so it might work.
*
* The main problem with OPTi is that some timings for master
* and slave must be the same. For example, if you have master
* PIO 3 and slave PIO 0, driver have to set some timings of
* master for PIO 0. Second problem is that opti621_set_pio_mode
* got only one drive to set, but have to set both drives.
* This is solved in compute_pios. If you don't set
* the second drive, compute_pios use ide_get_best_pio_mode
* for autoselect mode (you can change it to PIO 0, if you want).
* If you then set the second drive to another PIO, the old value
* (automatically selected) will be overrided by yours.
* There is a 25/33MHz switch in configuration
* register, but driver is written for use at any frequency.
*
* Version 0.1, Nov 8, 1996
* by Jaromir Koutek, for 2.1.8.
* Initial version of driver.
*
* Version 0.2
* Number 0.2 skipped.
*
* Version 0.3, Nov 29, 1997
* by Mark Lord (probably), for 2.1.68
* Updates for use with new IDE block driver.
*
* Version 0.4, Dec 14, 1997
* by Jan Harkes
* Fixed some errors and cleaned the code.
*
* Version 0.5, Jan 2, 1998
* by Jaromir Koutek
* Updates for use with (again) new IDE block driver.
* Update of documentation.
*
* Version 0.6, Jan 2, 1999
* by Jaromir Koutek
* Reversed to version 0.3 of the driver, because
* 0.5 doesn't work.
