Retronetworking

h1. PCIe->PCI bridges

Many interesting chipsets for retro networking are equipped with the older PCI bus instead of the current PCIe interface.

There are a number of PCIe->PCI bridge chipsets available, with varying levels of quality/reliability.

If you have tested a new chipset or revision of a bridge chip listed here, please update this page.

h3. ASMedia ASM1083/1085

The ASMedia ASM1083 and ASM1085 chipsets seem to have problems with interrupt handling.

This will flood the kernel log with messages like:

<pre>pcieport [...]: PME: Spurious native interrupt!</pre>

ASM1083/1085 also seem to have other issues related to DMA/IRQ handling. Many soundcards seem to have issues as well.

Tested revisions:

- ASM1085, datecode: 1040 (40th week 2010) (not working)

- ASM1083, datecode: 1218 (18th week 2012) (not working)

- ASM1083, datecode: 1346 (46th week 2013), rev 04 (working with pcie_aspm=off cmdline)

- ASM1083, datecode: 1350 (50th week 2013), rev 03 (not working)

Cards with a revision (check lspci) higher than 03 seem to work better. With ASPM enabled (by default), they will still flood messages about interrupts.

*Make sure you get Revision 04 or higher and disable ASPM!*

h3. ITE IT8892E

Common on many Gigabyte motherboards. Untested.

h3. Diodes/Pericom PI7C9X111SL

Common on "PCI-E To Dual PCI Riser Cards" and some PCIe->PCI adapters. Untested.

h3. Diodes/Pericom PI7C9X113SL

Untested.

h3. PLX chips

Untested.

h3. TI XIO2001

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.
