- Enhance the demand paging test to allow for better reporting and stressing
of UFFD performance.
- Convert the steal time test to generate TAP-friendly output.
- Fix a flaky false positive in the xen_shinfo_test due to comparing elapsed
time across two different clock domains.
- Skip the MONITOR/MWAIT test if the host doesn't actually support MWAIT.
- Avoid unnecessary use of "sudo" in the NX hugepage test to play nice with
running in a minimal userspace environment.
- Allow skipping the RSEQ test's sanity check that the vCPU was able to
complete a reasonable number of KVM_RUNs, as the assert can fail on a
completely valid setup. If the test is run on a large-ish system that is
otherwise idle, and the test isn't affined to a low-ish number of CPUs, the
vCPU task can be repeatedly migrated to CPUs that are in deep sleep states,
which results in the vCPU having very little net runtime before the next
migration due to high wakeup latencies.
