So let me get this straight -- you're suggesting I add a quirk for
every PCI chipset that doesn't support MSI? There are probably
hundreds of these... anything made before 1999 or so, and probably a
bunch since then too.
There is a NVIDIA G96 GPU (which is PCIe only) hanging off of a PCIe
- PCI bridge (all on one card), which is plugged into a motherboard
with the 430FX chipset (PCI 2.0 supported).
The GPU PCI device, of course, has full support for MSI. However my
understanding is that MSI won't actually

Hmmm, so my suggestion is
1. Add quirk to detect 430FX chipset, if detected, disable MSI in this platform.

2. Append boot argument pci=nomsi in OS command line when the

Hi Brian,
From your 01:00.0 VGA compatible controller PCI config register, it supports
1 MSI vector, so I think this
card has no problem. But you didn't answer what's the pci_enable_msi() return

You can check PCI bus whether support MSI like:
