When comparing the Focal 5.4 generic AMD64 kernel test output and Focal 5.4 KVM AMD64 kernel test output, you can see the generic kernel will pass with:
PASS: clflush (present) PASS: sfence (present) PASS: lfence (present) PASS: mfence (present) PASS: clflushopt (ABSENT) PASS: clwb (ABSENT) PASS: invalid clwb PASS: pcommit (ABSENT) SUMMARY: 8 tests PASS memory (8 tests) Instead the KVM kernel will fail with: FAIL: clflushopt (ABSENT) FAIL: clwb (ABSENT) I wonder what's the difference here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1831449 Title: memory in ubuntu_kvm_unit_tests fails (clflushopt / clwb ABSENT) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1831449/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
