These include: o Interrupts, including NMI and SMI, including the interrupt vector when defined. o Faults, exceptions including the fault vector. - Page faults additionally include the page fault address, when in context. o Event handler returns, including IRET and RSM. o VM exits and VM entries.¹ - VM exits include the values written to the “exit reason” and “exit qualification” VMCS fields. INIT and SIPI events. o TSX aborts, including the abort status returned for the RTM instructions. o Shutdown. Additionally, it provides indication of the status of the Interrupt Flag (IF), to indicate when interrupts are masked" ARM CoreSight: - Use advertised caps/min_interval as default sample_period on ARM spe. - Update deduction of TRCCONFIGR register for branch broadcast on ARM's CoreSight ETM.

ARM: - Add support for HiSilicon CPA PMU aliasing. perf stat: - Fix forked applications enablement of counters. - The 'slots' should only be printed on a different order than the one specified on the command line when 'topdown' events are present, fix it. Miscellaneous: - Sync msr-index, cpufeatures header files with the kernel sources. - Stop using some deprecated libbpf APIs in 'perf trace'. - Fix some spelling mistakes. - Refactor the maps pointers usage to pave the way for using refcount debugging. - Only offer the --tui option on perf top, report and annotate when perf was built with libslang. - Don't mention --to-ctf in 'perf data --help' when not linking with the required library, libbabeltrace. - Use ARRAY_SIZE() instead of ad hoc equivalent, spotted by array_size.cocci. - Enhance the matching of sub-commands abbreviations: 'perf c2c rec' -> 'perf c2c record' 'perf c2c recport -> error - Set build-id using build-id header on new mmap records. - Fix generation of 'perf --version' string. perf test: - Add test for the arm_spe event. - Add test to check unwinding using fame-pointer (fp) mode on arm64. - Make metric testing more robust in 'perf test'. - Add error message for unsupported branch stack cases. libperf: - Add API for allocating new thread map array. - Fix typo in perf_evlist__open() failure error messages in libperf tests. perf c2c: - Replace bitmap_weight() with bitmap_empty() where appropriate" * tag 'perf-tools-for-v5.18-2022-03-26' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (143 commits) perf evsel: Improve AMD IBS (Instruction-Based Sampling) error handling messages perf python: Add perf_env stubs that will be needed in evsel__open_strerror() perf tools: Enhance the matching of sub-commands abbreviations libperf tests: Fix typo in perf_evlist__open() failure error messages tools arm64: Import cputype.h perf lock: Add -F/--field option to control output perf lock: Extend struct lock_key to have print function perf lock: Add --synth=no option for record tools headers cpufeatures: Sync with the kernel sources tools headers cpufeatures: Sync with the kernel sources perf stat: Fix forked applications enablement of counters tools arch x86: Sync the msr-index.h copy with the kernel sources perf evsel: Make evsel__env() always return a valid env perf build-id: Fix spelling mistake "Cant" -> "Can't" perf header: Fix spelling mistake "could't" -> "couldn't" perf script: Add 'brstackinsnlen' for branch stacks perf parse-events: Move slots only with topdown perf ftrace latency: Update documentation perf ftrace latency: Add -n/--use-nsec option perf tools: Fix version kernel tag ...
