|---|---|---|---|
| 2 | |||
| 3 | Many interesting chipsets for retro networking are equipped with the older PCI bus instead of the current PCIe interface. |
||
| 4 | There are a number of PCIe->PCI bridge chipsets available, with varying levels of quality/reliability. |
||
| 5 | |||
| 6 | h3. ASMedia ASM1083/1085 |
||
| 7 | |||
| 8 | The ASMedia ASM1083 and ASM1085 chipsets seem to have problems with interrupt handling. |
||
| 9 | This will flood the kernel log with messages like: |
||
| 10 | <pre>pcieport [...]: PME: Spurious native interrupt!</pre> |
||
| 11 | ASM1083/1085 also seem to have other issues related to DMA/IRQ handling. Many soundcards seem to have issues as well. |
||
| 12 | |||
| 13 | Tested revisions: |
||
| 14 | - ASM1085, datecode: 1040 (40th week 2010) |
||
| 15 | - ASM1083, datecode: 1218 (18th week 2012) |
||
| 16 | - ASM1083, datecode: 1346 (46th week 2013) |
||
| 17 | - ASM1083, datecode: 1350 (50th week 2013) |
||
| 18 | |||
| 19 | There are reports online of cards with PCI revisions higher than Rev. 03 being fixed. This does not seem to be true. |
||
| 20 | |||
| 21 | h3. ITE IT8892E |
||
| 22 | |||
| 23 | Common on many Gigabyte motherboards. Untested. |
||
| 24 | |||
| 25 | |||
| 26 | h3. Diodes/Pericom PI7C9X111SL |
||
| 27 | |||
| 28 | Common on "PCI-E To Dual PCI Riser Cards" and some PCIe->PCI adapters. Untested. |
||
| 29 | |||
| 30 | |||
| 31 | h3. Diodes/Pericom PI7C9X113SL |
||
| 32 | |||
| 33 | Untested. |
||
| 34 | |||
| 35 | |||
| 36 | h3. PLX chips |
||
| 37 | |||
| 38 | Untested. |
||
| 39 | |||
| 40 | h3. TI XIO2001 |
||
| 41 | |||
| 42 | 2 | laforge | Issues reported with Sangoma Wanpipe cards, specifically: Cards enumerate quite fine, are visible in lusb and driver binds to it. However, their interrupts never reach Linux, neither the registered interrupt handler, nor does the counter in /proc/interrupts ever count up. |
