[PATCH v3 0/1] ARM_PMU: Trap PMCR when MDCR_EL2.TPMCR is set

Posted by Smail AIDER via 3 months ago

Trap PMCR_EL0 or PMCR accesses to EL2 when MDCR_EL2.TPMCR is set.
Similar to MDCR_EL2.TPM, MDCR_EL2.TPMCR allows trapping EL0 and EL1
accesses to the PMCR register to EL2.

Changes from v2:
- Squashed patches, no other changes.

Changes from v1:
- Some refactoring to simplify code.

Applied to target-arm.next for 10.2, thanks.

PS: a cover letter is not necessary for a single patch,
only for multiple patch series.
