Linus Torvalds 10a3efd0fe perf tools changes for v5.13: 1st batch 
perf stat:
 
 - Add support for hybrid PMUs to support systems such as Intel Alderlake
   and its BIG/little core/atom cpus.
 
 - Introduce 'bperf' to share hardware PMCs with BPF.
 
 - New --iostat option to collect and present IO stats on Intel hardware.
 
   This functionality is based on recently introduced sysfs attributes
   for Intel® Xeon® Scalable processor family (code name Skylake-SP):
 
     commit bb42b3d397 ("perf/x86/intel/uncore: Expose an Uncore unit to IIO PMON mapping")
 
   It is intended to provide four I/O performance metrics in MB per each
   PCIe root port:
 
    - Inbound Read: I/O devices below root port read from the host memory
    - Inbound Write: I/O devices below root port write to the host memory
    - Outbound Read: CPU reads from I/O devices below root port
    - Outbound Write: CPU writes to I/O devices below root port
 
 - Align CSV output for summary.
 
 - Clarify --null use cases: Assess raw overhead of 'perf stat' or
   measure just wall clock time.
 
 - Improve readability of shadow stats.
 
 perf record:
 
 - Change the COMM when starting tha workload so that --exclude-perf
   doesn't seem to be not honoured.
 
 - Improve 'Workload failed' message printing events + what was exec'ed.
 
 - Fix cross-arch support for TIME_CONV.
 
 perf report:
 
 - Add option to disable raw event ordering.
 
 - Dump the contents of PERF_RECORD_TIME_CONV in 'perf report -D'.
 
 - Improvements to --stat output, that shows information about PERF_RECORD_ events.
 
 - Preserve identifier id in OCaml demangler.
 
 perf annotate:
 
 - Show full source location with 'l' hotkey in the 'perf annotate' TUI.
 
 - Add line number like in TUI and source location at EOL to the 'perf annotate' --stdio mode.
 
 - Add --demangle and --demangle-kernel to 'perf annotate'.
 
 - Allow configuring annotate.demangle{,_kernel} in 'perf config'.
 
 - Fix sample events lost in stdio mode.
 
 perf data:
 
 - Allow converting a perf.data file to JSON.
 
 libperf:
 
 - Add support for user space counter access.
 
 - Update topdown documentation to permit rdpmc calls.
 
 perf test:
 
 - Add 'perf test' for 'perf stat' CSV output.
 
 - Add 'perf test' entries to test the hybrid PMU support.
 
 - Cleanup 'perf test daemon' if its 'perf test' is interrupted.
 
 - Handle metric reuse in pmu-events parsing 'perf test' entry.
 
 - Add test for PE executable support.
 
 - Add timeout for wait for daemon start in its 'perf test' entries.
 
 Build:
 
 - Enable libtraceevent dynamic linking.
 
 - Improve feature detection output.
 
 - Fix caching of feature checks caching.
 
 - First round of updates for tools copies of kernel headers.
 
 - Enable warnings when compiling BPF programs.
 
 Vendor specific events:
 
 Intel:
 
 - Add missing skylake & icelake model numbers.
 
 arm64:
 
 - Add Hisi hip08 L1, L2 and L3 metrics.
 
 - Add Fujitsu A64FX PMU events.
 
 PowerPC:
 
 - Initial JSON/events list for power10 platform.
 
 - Remove unsupported power9 metrics.
 
 AMD:
 
 - Add Zen3 events.
 
 - Fix broken L2 Cache Hits from L2 HWPF metric.
 
 - Use lowercases for all the eventcodes and umasks.
 
 Hardware tracing:
 
 arm64:
 
 - Update CoreSight ETM metadata format.
 
 - Fix bitmap for CS-ETM option.
 
 - Support PID tracing in config.
 
 - Detect pid in VMID for kernel running at EL2.
 
 Arch specific:
 
 MIPS:
 
 - Support MIPS unwinding and dwarf-regs.
 
 - Generate mips syscalls_n64.c syscall table.
 
 PowerPC:
 
 - Add support for PERF_SAMPLE_WEIGH_STRUCT on PowerPC.
 
 - Support pipeline stage cycles for powerpc.
 
 libbeauty:
 
 - Fix fsconfig generator.
