[PATCH V2 1/4] perf/x86/intel/uncore: Constify intel_uncore_ops
From: Rikard Falkeborn
Date: Fri Jun 11 2021 - 16:51:51 EST
These are not modified, so make them const to allow the compiler to put
them in read-only memory. To be able to constify all existing
intel_uncore_ops, introduce rkl_uncore_msr_ops to avoid having to modify
skl_uncore_msr_ops at run-time.
Signed-off-by: Rikard Falkeborn <rikard.falkeborn@xxxxxxxxx>
---
Changes since v1:
- Introduce rkl_uncore_msr_ops to be able to constify skl_uncore_msr_ops
