As multi-size THP support is added, not all THPs are PMD-mapped, thus
during a huge page split, there is no need to always split PMD mapping

Hi!
When running selftests for our subsystem in our CI we'd like all
tests to pass. Currently some tests use SKIP for cases they
expect to fail, because the kselftest_harness limits the return

We always use skip in combination with exit_code being 0

For generic test harness code it's more useful to deal with exit

According to the spec we should always print a # if we add

Currently some tests report skip for things they expect to fail
e.g. when given combination of parameters is known to be unsupported.
This is confusing because in an ideal test environment and fully
featured kernel no tests should be skipped.
Selftest summary line already includes xfail and xpass
SCTP does not support IP_LOCAL_PORT_RANGE and we know it,
so use XFAIL instead of SKIP.

Add a test for verifying overflow interrupt. Currently, it relies on
overflow support on cycle/instret events. This test works for cycle/
instret events which support sampling via hpmcounters on the platform.
There are no ISA extensions to detect if a platform supports that. Thus,
this test will fa

Create a vcpu with vpmu would be a common requirement for the vpmu test,
so add the helper function for the vpmu vcpu creation. And use those
helper function in the vpmu_counter_access.c test.
Use this chance to delete the meaningless ASSERT about the pmuver,
because KVM does not advertise an IMP_
The test is inspired by the pmu_event_filter_test which implemented by x86. On
the arm64 platform, there is the same ability to set the pmu_event_filter
through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64.
The series first create the helper function which can be used
for th
Introduce pmu_event_filter_test for arm64 platforms. The test configures
PMUv3 for a vCPU, and sets different pmu event filters for the vCPU, and
check if the guest can see those events which user allow and can't use
those events which use deny.
This test refactor the create_vpmu_vm() and make it
Add the invalid filter test which sets the filter beyond the event
space and sets the invalid action to double check if the
KVM_ARM_VCPU_PMU_V3_FILTER will return the expected error.
