 perf tools for v5.8:
 
  - Further Intel PT call-trace fixes
 
  - Improve SELinux docs and tool warnings
 
  - Fix race at exit in 'perf record' using eventfd.
 
  - Add missing build tests to the default set of 'make -C tools/perf build-test'
 
  - Sync msr-index.h getting new AMD MSRs to decode and filter in 'perf trace'.
 
  - Fix fallback to libaudit in 'perf trace' for arches not using per-arch *.tbl files.
 
  - Fixes for 'perf ftrace'.
 
  - Fixes and improvements for the 'perf stat' metrics.
 
  - Use dummy event to get PERF_RECORD_{FORK,MMAP,etc} while synthesizing
    those metadata events for pre-existing threads.
 
  - Fix leaks detected using clang tooling.
 
  - Improvements to PMU event metric testing.
 
  - Report summary for 'perf stat' interval mode at the end, summing up
    all the intervals.
 
  - Improve pipe mode, i.e. this now works as expected, continuously
    dumping samples:
 
     # perf record -g -e raw_syscalls:sys_enter | perf --no-pager script
 
  - Fixes for event grouping, detecting incompatible groups such as:
 
      # perf stat -e '{cycles,power/energy-cores/}' -v
      WARNING: group events cpu maps do not match, disabling group:
        anon group { power/energy-cores/, cycles }
          power/energy-cores/: 0
          cycles: 0-7
 
  - Fixes for 'perf probe': blacklist address checking, number of
    kretprobe instances, etc.
 
  - JIT processing improvements and fixes plus the addition of a 'perf
    test' entry for the java demangler.
 
  - Add support for synthesizing first/last level cache, TLB and remove
    access events from HW tracing in the auxtrace code, first to use is
    ARM SPE.
 
  - Vendor events updates and fixes, including for POWER9 and Intel.
 
  - Allow using ~/.perfconfig for removing the ',' separators in 'perf
    stat' output.
 
  - Opt-in support for libpfm4.

 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.
 
 Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
 needs to be investigated, haven't tested with CC=gcc, but should be the same
 problem:
 
 + make ARCH= CROSS_COMPILE= EXTRA_CFLAGS= LIBCLANGLLVM=1 -C /git/linux/tools/perf O=/tmp/build/perf CC=clang

Merge tag 'perf-tools-2020-06-02' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tooling updates from Arnaldo Carvalho de Melo:
 "These are additional changes to the perf tools, on top of what Ingo
  already submitted.

   - Further Intel PT call-trace fixes

   - Improve SELinux docs and tool warnings

   - Fix race at exit in 'perf record' using eventfd.

   - Add missing build tests to the default set of 'make -C tools/perf
     build-test'

   - Sync msr-index.h getting new AMD MSRs to decode and filter in 'perf
     trace'.

   - Fix fallback to libaudit in 'perf trace' for arches not using
     per-arch *.tbl files.

   - Fixes for 'perf ftrace'.

   - Fixes and improvements for the 'perf stat' metrics.

   - Use dummy event to get PERF_RECORD_{FORK,MMAP,etc} while
     synthesizing those metadata events for pre-existing threads.

   - Fix leaks detected using clang tooling.

   - Improvements to PMU event metric testing.

   - Report summary for 'perf stat' interval mode at the end, summing up
     all the intervals.

   - Improve pipe mode, i.e. this now works as expected, continuously
     dumping samples:

        # perf record -g -e raw_syscalls:sys_enter | perf --no-pager script

   - Fixes for event grouping, detecting incompatible groups such as:

        # perf stat -e '{cycles,power/energy-cores/}' -v
        WARNING: group events cpu maps do not match, disabling group:
          anon group { power/energy-cores/, cycles }
            power/energy-cores/: 0
            cycles: 0-7

   - Fixes for 'perf probe': blacklist address checking, number of
     kretprobe instances, etc.

   - JIT processing improvements and fixes plus the addition of a 'perf
     test' entry for the java demangler.

   - Add support for synthesizing first/last level cache, TLB and remove
     access events from HW tracing in the auxtrace code, first to use is
     ARM SPE.

   - Vendor events updates and fixes, including for POWER9 and Intel.

   - Allow using ~/.perfconfig for removing the ',' separators in 'perf
     stat' output.

   - Opt-in support for libpfm4"
