https://bugzilla.kernel.org/show_bug.cgi?id=206579 --- Comment #27 from muncrief (rmuncrief@xxxxxxxxxxxxxxx) --- Created attachment 287667 --> https://bugzilla.kernel.org/attachment.cgi?id=287667&action=edit avic_inhibit_reasons debug information Oh, that was so cool Suravee! I applied the initial svm.c and debug patch and tested both host-passthrough and EPYC-IBPB configurations, and avic failed with both. With host-passthrough the avic_inhibit_reasons value immediately changed from 0 to 20, and then a few seconds later changed to 28. With the EPYC-IBPB the avic_inhibit_reasons value immediately changed from 0 to 16, and then a few seconds later changed to 24. I wanted to give you as much accurate information as possible so I attached the avic_inhibit_reason values, my physical machine and domain capabilities, and the command lines and XML files used in the tests for each configuration to this comment. By the way, I ran multiple tests with both configurations. I used the defaults, then explicit 1-8-2 topology, and with host-passthrough I removed the cache passthrough and VM hiding. I also ran all tests again using the second variation of the svm.c patch. Unfortunately nothing changed the avic failure though. I hope this information helps, and am looking forward to assisting you gentlemen further in any way possible. -- You are receiving this mail because: You are watching the assignee of the bug.
