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 during it enable MSI fail. You can check PCI bus whether support MSI like: cat /sys/bus/pci/devices/00:0e.0/msi_bus Other, do you call pci_enable_device() before pci_enable_msi() ?

The problem here is that pci_enable_msi() succeeds, but it probably shouldn't. I don't know all the details about MSI, but doesn't the CPU or (L)APIC have to support it? In this case, it's a P200MMX on a 430FX chipset board. Both quite ancient... So given that the PCI device itself supports MSI, how do we tell that it shouldn't actually get turned on? -ilia> > On 2014/7/4 8:35, Brian Becker wrote: >> I mistakenly only replied to Yijing Wang the first time.

Yijing, cat /sys/bus/pci/devices/0000\:00\:0e.0/msi_bus returns 1, suggesting that it supports MSI. However, this "00:0e.0 PCI bridge: PLX Technology, Inc. PEX8112 x1 Lane PCI Express-to-PCI Bridge (rev aa)" is a component of the addin card. Wouldn't the lack of support for MSI by the chipset "00:00.0 Host bridge: Intel Corporation 430FX - 82437FX TSC [Triton I] (rev 01)" preclude the use of MSI with buses attached via a bridge?
