7 * The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards. 8 * The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards.
8 * Writing the driver was quite simple, since most of the job is
9 * done by the generic pci-ide support.
10 * The hard part was finding the CY82C693's datasheet on Cypress's
11 * web page :-(. But Altavista solved this problem :-).
12 *
13 *
14 * Notes:
15 * - I recently got a 16.8G IBM DTTA, so I was able to test it with
16 * a large and fast disk - the results look great, so I'd say the
17 * driver is working fine :-)
18 * hdparm -t reports 8.17 MB/sec at about 6% CPU usage for the DTTA
19 * - this is my first linux driver, so there's probably a lot of room
20 * for optimizations and bug fixing, so feel free to do it.
21 * - if using PIO mode it's a good idea to set the PIO mode and
22 * 32-bit I/O support (if possible), e.g. hdparm -p2 -c1 /dev/hda
23 * - I had some problems with my IBM DHEA with PIO modes < 2
24 * (lost interrupts) ?????
25 * - first tests with DMA look okay, they seem to work, but there is a
26 * problem with sound - the BusMaster IDE TimeOut should fixed this
27 *
28 * Ancient History:
29 * AMH@1999-08-24: v0.34 init_cy82c693_chip moved to pci_init_cy82c693
30 * ASK@1999-01-23: v0.33 made a few minor code clean ups
31 * removed DMA clock speed setting by default
32 * added boot message
33 * ASK@1998-11-01: v0.32 added support to set BusMaster IDE TimeOut
34 * added support to set DMA Controller Clock Speed
35 * ASK@1998-10-31: v0.31 fixed problem with setting to high DMA modes
36 * on some drives.
37 * ASK@1998-10-29: v0.3 added support to set DMA modes
38 * ASK@1998-10-28: v0.2 added support to set PIO modes
39 * ASK@1998-10-27: v0.1 first version - chipset detection

11 *
12 * OPTi is trademark of OPTi, Octek is trademark of Octek.
13 *
14 * I used docs from OPTi databook, from ftp.opti.com, file 9123-0002.ps
15 * and disassembled/traced setupvic.exe (DOS program).
16 * It increases kernel code about 2 kB.
17 * I don't have this card no more, but I hope I can get some in case
18 * of needed development.
19 * My card is Octek PIDE 1.01 (on card) or OPTiViC (program).
20 * It has a place for a secondary connector in circuit, but nothing
21 * is there. Also BIOS says no address for
22 * secondary controller (see bellow in ide_init_opti621).
23 * I've only tested this on my system, which only has one disk.
24 * It's Western Digital WDAC2850, with PIO mode 3. The PCI bus
25 * is at 20 MHz (I have DX2/80, I tried PCI at 40, but I got random
26 * lockups). I tried the OCTEK double speed CD-ROM and
27 * it does not work! But I can't boot DOS also, so it's probably
28 * hardware fault. I have connected Conner 80MB, the Seagate 850MB (no
29 * problems) and Seagate 1GB (as slave, WD as master). My experiences
30 * with the third, 1GB drive: I got 3MB/s (hdparm), but sometimes
31 * it slows to about 100kB/s! I don't know why and I have
32 * not this drive now, so I can't try it again.
33 * I write this driver because I lost the paper ("manual") with
34 * settings of jumpers on the card and I have to boot Linux with
35 * Loadlin except LILO, cause I have to run the setupvic.exe program
36 * already or I get disk errors (my test: rpm -Vf
37 * /usr/X11R6/bin/XF86_SVGA - or any big file).
38 * Some numbers from hdparm -t /dev/hda:
39 * Timing buffer-cache reads: 32 MB in 3.02 seconds =10.60 MB/sec
40 * Timing buffered disk reads: 16 MB in 5.52 seconds = 2.90 MB/sec
41 * I have 4 Megs/s before, but I don't know why (maybe changes
42 * in hdparm test).
43 * After release of 0.1, I got some successful reports, so it might work.
44 *
45 * The main problem with OPTi is that some timings for master
46 * and slave must be the same. For example, if you have master
47 * PIO 3 and slave PIO 0, driver have to set some timings of
48 * master for PIO 0. Second problem is that opti621_set_pio_mode
49 * got only one drive to set, but have to set both drives.
50 * This is solved in compute_pios. If you don't set
51 * the second drive, compute_pios use ide_get_best_pio_mode
52 * for autoselect mode (you can change it to PIO 0, if you want).
53 * If you then set the second drive to another PIO, the old value
54 * (automatically selected) will be overrided by yours.
55 * There is a 25/33MHz switch in configuration
56 * register, but driver is written for use at any frequency.
57 *
58 * Version 0.1, Nov 8, 1996
59 * by Jaromir Koutek, for 2.1.8.
60 * Initial version of driver.
61 *
62 * Version 0.2
63 * Number 0.2 skipped.
64 *
65 * Version 0.3, Nov 29, 1997
66 * by Mark Lord (probably), for 2.1.68
67 * Updates for use with new IDE block driver.
68 *
69 * Version 0.4, Dec 14, 1997
70 * by Jan Harkes
71 * Fixed some errors and cleaned the code.
72 *
73 * Version 0.5, Jan 2, 1998
74 * by Jaromir Koutek
75 * Updates for use with (again) new IDE block driver.
76 * Update of documentation.
77 *
78 * Version 0.6, Jan 2, 1999
79 * by Jaromir Koutek
80 * Reversed to version 0.3 of the driver, because
81 * 0.5 doesn't work.
