https://bugzilla.kernel.org/show_bug.cgi?id=206579 --- Comment #46 from Anthony (anthonysanwo@xxxxxxxxxxxxxx) --- Suravee Suthikulpanit Just wanted to say thanks a lot for the latest patches - iommu/amd: Fix IOMMU AVIC not properly update the is_run bit in IRTE - https://lore.kernel.org/patchwork/patch/1208762/ This patch fixes the performance differences I saw when I was testing AVIC with your earlier patchsets. I believe this was what caused my confusion as because I found when AVIC was enabled I had worse performance at times so I thought it was due to me misunderstanding how things should be setup. kvm: svm: Introduce GA Log tracepoint for AVIC - https://lore.kernel.org/patchwork/patch/1208775/ This is perfect for people like me with limited understanding on things as it more easily tells you whether or not avic is working. On that point with the IOMMU AVIC fix i have had great results with my setup - which now as a total of 7 PCIe devices that are pass through to my Windows guest. Thanks again to everyone for all the hard work. -- You are receiving this mail because: You are watching the assignee of the bug.
