--- Comment #21 from Marti Raudsepp <ma...@juffo.org> --- (In reply to Joel Schopp from comment #20) > What updates are you looking for? Joerg's fix is now upstream. Yes, but there's still the issue with southbridge component isolation. You requested more information from me in comment #15 that I provided in comment #17. For background see comment #9 from Alex Williamson: > AMD would need to confirm it. IOMMU groups are based on hardware advertised > isolation via the PCIe ACS capability. Without this, or a device specific > quirk to take its place, IOMMU groups must assume that peer-to-peer between > functions of a multi-function device is possible and therefore that the > devices are not isolated. [...] > I think the path forward is to get confirmation from AMD that these function > are isolated from each other and add quirks to the kernel. Then you won't > have the device dependencies in vfio-pci. The override patch allows you to > do that with just a kernel boot parameter. There's no gurantee that > pci-assign will ever be fixed since it's being phased out. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
