Merge tag 'perf-core-2023-06-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf events updates from Ingo Molnar:
- Rework & fix the event forwarding logic by extending the core
interface.
This fixes AMD PMU events that have to be forwarded from the
core PMU to the IBS PMU.
- Add self-tests to test AMD IBS invocation via core PMU events
- Clean up Intel FixCntrCtl MSR encoding & handling
