Lucas De Marchi | 25985ed | 2011-03-30 22:57:33 -0300 | [diff] [blame] | 41 | * Publicly available from Intel web site. Errata documentation |

Alan | 2c5ff67 | 2006-12-04 16:33:20 +0000 | [diff] [blame] | 43 | * driver the list of errata that are relevant is below, going back to |
Alan Cox | d96212e | 2005-12-08 19:19:50 +0000 | [diff] [blame] | 44 | * PIIX4. Older device documentation is now a bit tricky to find. |
| 45 | * |
Thomas Weber | 8839316 | 2010-03-16 11:47:56 +0100 | [diff] [blame] | 46 | * The chipsets all follow very much the same design. The original Triton |
Lucas De Marchi | 25985ed | 2011-03-30 22:57:33 -0300 | [diff] [blame] | 47 | * series chipsets do _not_ support independent device timings, but this |
Alan Cox | d96212e | 2005-12-08 19:19:50 +0000 | [diff] [blame] | 48 | * is fixed in Triton II. With the odd mobile exception the chips then |
| 49 | * change little except in gaining more modes until SATA arrives. This |
Lucas De Marchi | 25985ed | 2011-03-30 22:57:33 -0300 | [diff] [blame] | 50 | * driver supports only the chips with independent timing (that is those |
Alan Cox | d96212e | 2005-12-08 19:19:50 +0000 | [diff] [blame] | 51 | * with SITRE and the 0x44 timing register). See pata_oldpiix and pata_mpiix |
| 52 | * for the early chip drivers. |
| 53 | * |
| 54 | * Errata of note: |
| 55 | * |
| 56 | * Unfixable |
| 57 | * PIIX4 errata #9 - Only on ultra obscure hw |
| 58 | * ICH3 errata #13 - Not observed to affect real hw |
| 59 | * by Intel |
| 60 | * |
| 61 | * Things we must deal with |
| 62 | * PIIX4 errata #10 - BM IDE hang with non UDMA |
| 63 | * (must stop/start dma to recover) |
| 64 | * 440MX errata #15 - As PIIX4 errata #10 |
| 65 | * PIIX4 errata #15 - Must not read control registers |
| 66 | * during a PIO transfer |
| 67 | * 440MX errata #13 - As PIIX4 errata #15 |
| 68 | * ICH2 errata #21 - DMA mode 0 doesn't work right |
| 69 | * ICH0/1 errata #55 - As ICH2 errata #21 |
| 70 | * ICH2 spec c #9 - Extra operations needed to handle |
| 71 | * drive hotswap [NOT YET SUPPORTED] |
| 72 | * ICH2 spec c #20 - IDE PRD must not cross a 64K boundary |
| 73 | * and must be dword aligned |
| 74 | * ICH2 spec c #24 - UDMA mode 4,5 t85/86 should be 6ns not 3.3 |
Alan Cox | c611bed | 2009-05-06 17:08:44 +0100 | [diff] [blame] | 75 | * ICH7 errata #16 - MWDMA1 timings are incorrect |
Alan Cox | d96212e | 2005-12-08 19:19:50 +0000 | [diff] [blame] | 76 | * |
| 77 | * Should have been BIOS fixed: |
| 78 | * 450NX: errata #19 - DMA hangs on old 450NX |
| 79 | * 450NX: errata #20 - DMA hangs on old 450NX |
| 80 | * 450NX: errata #25 - Corruption with DMA on old 450NX |
| 81 | * ICH3 errata #15 - IDE deadlock under high load |
| 82 | * (BIOS must set dev 31 fn 0 bit 23) |
| 83 | * ICH3 errata #18 - Don't use native mode |
