# HEAD: 2c47e7a74f445426d156278e339b7abb259e50de perf/core: Correct perf sampling with guest VMs

Performance events changes for v6.13:

- Uprobes:
- Add BPF session support (Jiri Olsa)
- Switch to RCU Tasks Trace flavor for better performance (Andrii Nakryiko)
- Massively increase uretprobe SMP scalability by SRCU-protecting the uretprobe lifetime (Andrii Nakryiko)
- Kill xol_area->slot_count (Oleg Nesterov)

- Core facilities:
- Implement targeted high-frequency profiling by adding the ability for an event to "pause" or "resume" AUX area tracing (Adrian Hunter)

- VM profiling/sampling:
- Correct perf sampling with guest VMs (Colton Lewis)

- New hardware support:
- x86/intel: Add PMU support for Intel ArrowLake-H CPUs (Dapeng Mi)

- Misc fixes and enhancements:
- x86/intel/pt: Fix buffer full but size is 0 case (Adrian Hunter)
- x86/amd: Warn only on new bits set (Breno Leitao)
- x86/amd/uncore: Avoid a false positive warning about snprintf truncation in amd_uncore_umc_ctx_init (Jean Delvare)
- uprobes: Re-order struct uprobe_task to save some space (Christophe JAILLET)
- x86/rapl: Move the pmu allocation out of CPU hotplug (Kan Liang)
- x86/rapl: Clean up cpumask and hotplug (Kan Liang)
- uprobes: Deuglify xol_get_insn_slot/xol_free_insn_slot paths (Oleg Nesterov)

Thanks,

Ingo
