Actually, this quirk doesn't make any difference until the iommu changes are in, so there's no reason to have this in v3.16, is there? I saw that Joerg applied those iommu changes to his core branch, which I assume will be merged for v3.17. So I'll move this to a pci/iommu branch, to be merged during the v3.17 merge window. > > --- > > > > drivers/pci/quirks.c | 2 ++ > > 1 file changed, 2 insertions(+) > > > > diff --git a/drivers/pci/quirks.c b/drivers/pci/quirks.c > > index 78a7df6..460c354 100644 > > --- a/drivers/pci/quirks.c > > +++ b/drivers/pci/quirks.c > > @@ -3405,6 +3405,8 @@ DECLARE_PCI_FIXUP_HEADER(PCI_VENDOR_ID_ASMEDIA, 0x1080, > > DECLARE_PCI_FIXUP_HEADER(0x10e3, 0x8113, quirk_use_pcie_bridge_dma_alias); > > /* ITE 8892, https://bugzilla.kernel.org/show_bug.cgi?id=73551 */ > > DECLARE_PCI_FIXUP_HEADER(0x1283, 0x8892, quirk_use_pcie_bridge_dma_alias); > > +/* Intel 82801, https://bugzilla.kernel.org/show_bug.cgi?id=44881#c49 */ > > +DECLARE_PCI_FIXUP_HEADER(0x8086, 0x244e, quirk_use_pcie_bridge_dma_alias); > > > > /* > > * AMD has indicated that the devices below do not support peer-to-peer > > -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
