[PATCH 0/2] KVM: selftests: Add tests for PEBS and MSR_IA32_DS_AREA

[Jinrong Liang <ljr.kernel@gmail.com>]

Hi,

This patch series introduces two tests to further enhance and
verify the functionality of the KVM subsystem. These tests focus
on MSR_IA32_DS_AREA and MSR_IA32_PERF_CAPABILITIES.

The first patch adds tests to verify the correct behavior when
trying to set MSR_IA32_DS_AREA with a non-classical address. It
checks that KVM is correctly faulting these non-classical addresses,
ensuring the accuracy and stability of the KVM subsystem.

The second patch includes a comprehensive PEBS test that checks all
possible combinations of PEBS-related bits in MSR_IA32_PERF_CAPABILITIES.
This helps to ensure the accuracy of PEBS functionality.

Feedback and suggestions are welcomed and appreciated.

Sincerely,
Jinrong Liang
