I will have a test later.
I have test this patch series using ACPI and guest with the patches you point out. Guest prints below logs and perf works well in guest. [ 0.000000] ACPI-PMU: Assign CPU 0 girq 23 level 0 [ 0.000000] ACPI-PMU: Assign CPU 1 girq 23 level 0 [ 0.000000] ACPI-PMU: Assign CPU 2 girq 23 level 0 [ 0.000000] ACPI-PMU: Assign CPU 3 girq 23 level 0 [...] [ 0.094782] ACPI-PMU: Setting up 4 PMUs for CPU type D07 Thanks, -- Shannon
