Add support for a further level, to support vendor/platform
sub-directories in future, which will be vendor/platform/cpu and
vendor/platform/sys.

456ef4c11c perf evsel: Emit warning about kernel not supporting the data page size sample_type bit
Before we had this unhelpful message:

  $ perf record --data-page-size sleep 1
  Error:
  The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cycles:u).
  /bin/dmesg | grep -i perf may provide additional information.
  $

Add support to the perf_missing_features variable to remember what
caused evsel__open() to fail and then use that information in
evsel__open_strerror().

  $ perf record --data-page-size sleep 1
  Error:
  Asking for the data page size isn't supported by this kernel.

bf53fc6b5f perf unwind: Fix separate debug info files when using elfutils' libdw's unwinder
elfutils needs to be provided main binary and separate debug info file
respectively. Providing separate debug info file instead of the main
binary is not sufficient.

One needs to try both supplied filename and its possible cache by its
build-id depending on the use case.

When using 'perf record's option '-I' or '--user-regs=' along with
argument '?' to list available register names, memory of variable 'os'
allocated by strdup() needs to be released before __parse_regs()
returns, otherwise memory leak will occur.

b2ce5dbc15 perf test: Fix metric parsing test
Commit e1c92a7fbb ("perf tests: Add another metric parsing test") add
another test for metric parsing. The test goes through all metrics
compiled for arch within pmu events and try to parse them.

Right now this test is failing in powerpc machine.

Result in power9 platform:

  [command]# ./perf test 10
  10: PMU events                                                      :
  10.1: PMU event table sanity                                        : Ok
  10.2: PMU event map aliases                                         : Ok
  10.3: Parsing of PMU event table metrics                            : Skip (some metrics failed)
  10.4: Parsing of PMU event table metrics with fake PMUs             : FAILED!

Issue is we are passing different runtime parameter value in
"expr__find_other" and "expr__parse" function which is called from
function `metric_parse_fake`.  And because of this parsing of hv-24x7
metrics is failing.

  [command]# ./perf test 10 -vv
  .....
  hv_24x7/pm_mcs01_128b_rd_disp_port01,chip=1/ not found
  expr__parse failed
  test child finished with -1
  ---- end ----
  PMU events subtest 4: FAILED!

This patch fix this issue and change runtime parameter value to '0' in
expr__parse function.

Result in power9 platform after this patch:

  [command]# ./perf test 10
  10: PMU events                                                      :
  10.1: PMU event table sanity                                        : Ok
  10.2: PMU event map aliases                                         : Ok
  10.3: Parsing of PMU event table metrics                            : Skip (some metrics failed)
  10.4: Parsing of PMU event table metrics with fake PMUs             : Ok

2a99ff822d perf tools: Add aarch64 registers to --user-regs
Previously, this command returns no help message on aarch64:

  -> ./perf record --user-regs=?

  available registers:
  Usage: perf record [<options>] [<command>]
      or: perf record [<options>] -- <command> [<options>]

With this change, the registers are listed.

  -> ./perf record --user-regs=?

  available registers: x0 x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 x12 x13 x14 x15 x16 x17 x18 x19 x20 x21 x22 x23 x24 x25 x26 x27 x28 x29 lr sp pc

It's also now possible to record subsets of registers on aarch64:

  -> ./perf record --user-regs=x4,x5 ls
  -> ./perf report --dump-raw-trace

94b69c615e perf test: Add shadow stat test
It calculates IPC from the cycles and instruction counts and compares it
with the shadow stat for both global aggregation (default) and no
aggregation mode.

 $ perf stat -a -A -e cycles,instructions sleep 1

   Performance counter stats for 'system wide':

  CPU0   39,580,880      cycles
  CPU1   45,426,945      cycles
  CPU2   31,151,685      cycles
  CPU3   55,167,421      cycles
  CPU0   17,073,564      instructions      #    0.43  insn per cycle
  CPU1   34,955,764      instructions      #    0.77  insn per cycle
  CPU2   15,688,459      instructions      #    0.50  insn per cycle
  CPU3   34,699,217      instructions      #    0.63  insn per cycle

       1.003275495 seconds time elapsed

In this example, the 'insn per cycle' should be matched to the number
for each cpu.  For CPU2, 0.50 = 15,688,459 / 31,151,685 .

Committer testing:

  # perf test shadow
  78: perf stat metrics (shadow stat) test                            : Ok

aae5ab854e RISC-V Fixes for 5.10-rc6
I've collected a handful of fixes over the past few weeks:
 
 * A fix to un-break the build-id argument to the vDSO build, which is necessary
   for the LLVM linker.
 * A fix to initialize the jump label subsystem, without which it (and all the
   stuff that uses it) doesn't actually function.
 * A fix to include <asm/barrier.h> from <vdso/processor.h>, without which some
   drivers won't compile.
 
 I know it's the holidays, but I had some hiccups getting this tested earlier
 this week so it's just going out now.  None of these are tremendously urgent,
 so if they don't make rc6 it's not a big deal.  I'll have some more fixes
 coming next week either way.

ca579827c9 perf tools for v5.10: 4th batch
- Fix die_entrypc() when DW_AT_ranges DWARF attribute not available.
 
 - Cope with broken DWARF (missing DW_AT_declaration) generated by some recent
   gcc versions.
 
 - Do not generate CGROUP metadata events when not asked to in 'perf record'.
 
 - Use proper CPU for shadow stats in 'perf stat'.
 
 - Update copy of libbpf's hashmap.c, silencing tools/perf build warning.
 
 - Fix return value in 'perf diff'.

 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.

         Ancient gcc get this wrong:

         But when using NO_LIBBPF we should not hit this, changes for that to happen will land in 5.11 as they require
