Subject: [PATCH v4 0/5] KVM: selftests: aarch64: Introduce pmu_event_filter_test
Date: Thu, 1 Feb 2024 21:56:49 -0500 [thread overview]
Message-ID: <20240202025659.5065-1-shahuang@redhat.com> (raw)
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 move some pmu common code from vpmu_counter_access to
lib/aarch64/vpmu.c and include/aarch64/vpmu.h, which can be used by
pmu_event_filter_test. Then fix a bug related to the [enable|disable]_counter,
and at last, implement the test itself.
Changelog:
----------
v3->v4:
- Rebased to the v6.8-rc2.
v2->v3:
- Check the pmceid in guest code instead of pmu event count since different
hardware may have different event count result, check pmceid makes it stable
on different platform. [Eric]
- Some typo fixed and commit message improved.
v1->v2:
- Improve the commit message. [Eric]
- Fix the bug in [enable|disable]_counter. [Raghavendra & Marc]
- Add the check if kvm has attr KVM_ARM_VCPU_PMU_V3_FILTER.
- Add if host pmu support the test event throught pmceid0.
- Split the test_invalid_filter() to another patch. [Eric]
