| |
Linus,
Please pull the latest perf/core git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2022-08-01
# HEAD: 326ecc15c61c349cd49d1700ff9e3e31c6fd1cd5 perf/x86/ibs: Add new IBS register bits into header
Perf events updates for this cycle are:
- Fix Intel Alder Lake PEBS memory access latency & data source profiling info bugs.
- Use Intel large-PEBS hardware feature in more circumstances, to reduce PMI overhead & reduce sampling data.
- Extend the lost-sample profiling output with the PERF_FORMAT_LOST ABI variant, which tells tooling the exact number of samples lost.
- Add new IBS register bits definitions.
- AMD uncore events: Add PerfMonV2 DF (Data Fabric) enhancements.
Thanks,
Ingo
