[RFC PATCH 0/3] Use TAP in some more KVM selftests

Many KVM selftests are completely silent. This has the disadvantage
for the users that they do not know what's going on here. For example,
some time ago, a tester asked me how to know whether a certain new
sub-test has been added to one of the s390x test binaries or not (which
he didn't compile on his own), which is hard to judge when there is no
output. So I finally went ahead and implemented TAP output in the
s390x-specific tests some months ago.

Now I wonder whether that could be a good strategy for the x86 and
generic tests, too? As a little RFC patch series, I've converted
three more KVM selftests to use TAP output. If we decide that this
is the right way to go, I can work on other tests later, too.

Thomas Huth (3):
KVM: selftests: Use TAP interface in the kvm_binary_stats_test
KVM: selftests: x86: Use TAP interface in the sync_regs test
KVM: selftests: x86: Use TAP interface in the tsc_msrs_test
