2be564b0 | 9 | * Documentation: |
1da177e4 | 10 | * |
1da177e4 LT |
11 | * Publically available from Intel web site. Errata documentation |
12 | * is also publically available. As an aide to anyone hacking on this | |
13 | * driver the list of errata that are relevant is below.going back to | |
14 | * PIIX4. Older device documentation is now a bit tricky to find. | |
15 | * | |
16 | * Errata of note: | |
17 | * | |
18 | * Unfixable | |
19 | * PIIX4 errata #9 - Only on ultra obscure hw | |
20 | * ICH3 errata #13 - Not observed to affect real hw | |
21 | * by Intel | |
22 | * | |
23 | * Things we must deal with | |
24 | * PIIX4 errata #10 - BM IDE hang with non UDMA | |
25 | * (must stop/start dma to recover) | |
26 | * 440MX errata #15 - As PIIX4 errata #10 | |
27 | * PIIX4 errata #15 - Must not read control registers | |
28 | * during a PIO transfer | |
29 | * 440MX errata #13 - As PIIX4 errata #15 | |
30 | * ICH2 errata #21 - DMA mode 0 doesn't work right | |
31 | * ICH0/1 errata #55 - As ICH2 errata #21 | |
32 | * ICH2 spec c #9 - Extra operations needed to handle | |
33 | * drive hotswap [NOT YET SUPPORTED] | |
34 | * ICH2 spec c #20 - IDE PRD must not cross a 64K boundary | |
35 | * and must be dword aligned | |
36 | * ICH2 spec c #24 - UDMA mode 4,5 t85/86 should be 6ns not 3.3 | |
37 | * | |
38 | * Should have been BIOS fixed: | |
39 | * 450NX: errata #19 - DMA hangs on old 450NX | |
40 | * 450NX: errata #20 - DMA hangs on old 450NX | |
41 | * 450NX: errata #25 - Corruption with DMA on old 450NX | |
42 | * ICH3 errata #15 - IDE deadlock under high load | |
43 | * (BIOS must set dev 31 fn 0 bit 23) | |
44 | * ICH3 errata #18 - Don't use native mode | |
