Subject: [PATCH v4 0/6] KVM: selftests: Improve PMU event filter settings and add test cases

Hi,

This patch series aims to improve the PMU event filter settings with a cleaner
and more organized structure and adds several test cases related to PMU event
filters.

These changes help to ensure that KVM's PMU event filter functions as expected
in all supported use cases.

Any feedback or suggestions are greatly appreciated.

Sincerely,
Jinrong Liang
