- Remove redundant newlines from error messages.
- Delete an unused variable in the AMX test (which causes build failures when
compiling with -Werror).
- Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an
error code other than ENOENT (a Hyper-V selftest bug resulted in an EMFILE,
and the test eventually got skipped).
- Fix TSC related bugs in several Hyper-V selftests.
- Fix a bug in the dirty ring logging test where a sem_post() could be left
pending across multiple runs, resulting in incorrect synchronization between
the main thread and the vCPU worker thread.
- Relax the dirty log split test's assertions on 4KiB mappings to fix false
positives due to the number of mappings for memslot 0 (used for code and
data that is NOT being dirty logged) changing, e.g. due to NUMA balancing.
- Have KVM's gtod_is_based_on_tsc() return "bool" instead of an "int" (the
function generates boolean values, and all callers treat the return value as
a bool).
