Subject: [PATCH v7 0/3] KVM: selftests: aarch64: Introduce pmu_event_filter_test
Date: Mon, 8 Apr 2024 23:03:13 -0400 [thread overview]
Message-ID: <20240409030320.182591-1-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 create the helper function which can be used
for the vpmu related tests. Then, it implement the test.
Changelog:
----------
v6->v7:
- Rebased to v6.9-rc3.
v5->v6:
- Rebased to v6.9-rc1.
- Collect RB.
- Add multiple filter test.
v4->v5:
- Rebased to v6.8-rc6.
- Refactor the helper function, make it fine-grained and easy to be used.
- Namimg improvements.
- Use the kvm_device_attr_set() helper.
- Make the test descriptor array readable and clean.
- Delete the patch which moves the pmu related helper to vpmu.h.
- Remove the kvm_supports_pmu_event_filter() function since nobody will run
this on a old kernel.
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]
