But otherwise I can't think of a reason. move to arch/x86/pci/fixup.c? it seems some other arch do support HT ... powerpc, mips? > >> Essentially >> the code for nv_msi_ht_cap_quirk could potentially be applied to all bridges as >> it is currently for NVIDIA and ALi bridges.. > > Sounds like it would save a fair amount of grief. it seems there is some difference. 8132 is some kind of HT tunnel, and the bridge is acctually pci-x bridge. mcp55 and ck804: is HT end device with several pcie bridges. also 8131 has problem with HT MSI?
