selftests: add headers_install to lib.mk

2018-10-18T07:18:13+00:00

[ Upstream commit b2d35fa5fc80c27e868e393dcab4c94a0d71737f ]

If the kernel headers aren't installed we can't build all the tests.
Add a new make target rule 'khdr' in the file lib.mk to generate the
kernel headers and that gets include for every test-dir Makefile that
includes lib.mk If the testdir in turn have its own sub-dirs the
top_srcdir needs to be set to the linux-rootdir to be able to generate
the kernel headers.

selftests: kvm: return Kselftest Skip code for skipped tests

2018-05-30T21:29:05+00:00

When kvm test is skipped because of unmet dependencies and/or unsupported
configuration, it exits with error which is treated as a fail by the
Kselftest framework. This leads to false negative result even when the test
could not be run.

Change it to return kselftest skip code when a test gets skipped to clearly
report that the test could not be run.

Change it to use ksft_exit_skip() when the test is skipped. In addition,
refine test_assert() message to include strerror() string and add explicit
check for EACCES to cleary identify when test doesn't run when access is
denied to resources required e.g: open /dev/kvm failed, rc: -1 errno: 13

KVM: selftests: exit with 0 status code when tests cannot be run

2018-05-11T09:21:12+00:00

Right now, skipped tests are returning a failure exit code if /dev/kvm does
not exists.  Consistently return a zero status code so that various scripts
over the interwebs do not complain.  Also return a zero status code if
the KVM_CAP_SYNC_REGS capability is not present, and hardcode in the
test the register kinds that are covered (rather than just using whatever
value of KVM_SYNC_X86_VALID_FIELDS is provided by the kernel headers).

kvm: selftests: add vmx_tsc_adjust_test

2018-04-16T15:50:23+00:00

The test checks the behavior of setting MSR_IA32_TSC in a nested guest,
and the TSC_OFFSET VMCS field in general.  It also introduces the testing
infrastructure for Intel nested virtualization.
