5f50e15c15 perf cpumap: Refactor cpu_map__build_map() 
Turn it into a cpu_aggr_map__new(). Pass helper functions. Refactor
builtin-stat calls to manually pass function pointers. Try to reduce
some copy-paste code.

3ac23d199c perf cpumap: Simplify equal function name 
Rename cpu_map__compare_aggr_cpu_id() to aggr_cpu_id__equal(), the
cpu_map part of the name is misleading. Equal better describes the
function than compare.

Switch to const pointer rather than value as struct given the number of
variables in aggr_cpu_id().

01843ca019 perf stat: Correct aggregation CPU map 
Switch the perf_cpu_map in aggr_update_shadow from
the evlist to the counter's cpu map, so the index is appropriate. This
addresses a problem where uncore counts, with a cpumap like:
$ cat /sys/devices/uncore_imc_0/cpumask
0,18
Don't aggregate counts in CPUs based on the index of those values in the
cpumap (0 and 1) but on the actual CPU (0 and 18). Thereby correcting
metric calculations in per-socket mode for counters without a full

dcffc5ebb8 perf evsel: Improve error message for uncore events 
When a group has multiple events and the leader fails it can yield
errors like:

  $ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true
  Error:
  The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (uncore_imc/cas_count_read/).
  /bin/dmesg | grep -i perf may provide additional information.

However, when not the group leader <not supported> is given:

  $ perf stat -e '{instructions,uncore_imc/cas_count_read/}' /bin/true
  ...
           1,619,057      instructions
     <not supported> MiB  uncore_imc/cas_count_read/

This is necessary because get_group_fd will fail if the leader fails and
is the direct result of the check on line 750 of builtin-stat.c in
stat_handle_error that returns COUNTER_SKIP for the latter case.

This patch improves the error message to:

  $ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true
  Error:
  Invalid event (uncore_imc/cas_count_read/) in per-thread mode, enable system wide with '-a'.

v2. Changed the test to use !target__has_cpu as suggested by Namhyung Kim.

d5962fb7d6 perf annotate: Avoid TUI crash when navigating in the annotation of recursive functions 
In 'perf report', entering a recursive function from inside of itself
(either directly of indirectly through some other function) results in
calling symbol__annotate2 multiple() times, and freeing the whole
disassembly when exiting from the innermost instance.

The first issue causes the function's disassembly to be duplicated, and
the latter a heap use-after-free (and crash) when trying to access the
disassembly again.

I reproduced the bug on perf 5.11.22 (Ubuntu 20.04.3 LTS) and 5.16.rc8
with the following testcase (compile with gcc recursive.c -o recursive).
To reproduce:

- perf record ./recursive
- perf report
- enter fibonacci and annotate it
- move the cursor on one of the "callq fibonacci" instructions and press enter
  - at this point there will be two copies of the function in the disassembly
- go back by pressing q, and perf will crash

  #include <stdio.h>

  int fibonacci(int n)
  {
      if(n <= 2) return 1;
      return fibonacci(n-1) + fibonacci(n-2);
  }

  int main()
  {
      printf("%d\n", fibonacci(40));
  }

This patch addresses the issue by annotating a function and freeing the
associated memory on exit only if no annotation is already present, so
that a recursive function is only annotated on entry.

e3304c2135 perf sort: Include global and local variants for p_stage_cyc sort key 
Sort key 'p_stage_cyc' is used to present the latency cycles spent in
pipeline stages.

perf has local 'p_stage_cyc' sort key to display this info. There is no
global variant available for this sort key. The local variant shows
latency in a single sample, whereas the global value will be useful to
present the total latency (sum of latencies) in the hist entry. It
represents the latency number multiplied by the number of samples.

Add global ('p_stage_cyc') and local variant ('local_p_stage_cyc') for
this sort key. Use 'local_p_stage_cyc' as default option for "mem" sort
mode.

Also add this to the list of dynamic sort keys and made the
"dynamic_headers" and "arch_specific_sort_keys" as static.

aca48b2dd1 ARM: SoC devicetree changes for v5.17 
As usual, this is the bulk of the updates for the SoC tree, adding
 more devices to existing files, addressing issues from ever improving
 automated checking, and fixing minor issues.
 
 The most interesting bits as usual are the new platforms.
 All the newly supported SoCs belong into existing families
 this time:
 
  - Qualcomm gets support for two newly announced platforms, both
    of which can now work in production environments: the SDX65
    5G modem that can run a minimal Linux on its Cortex-A7 core,
    and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
 
  - Renesas adds support for R-Car S4-8, the most recent automotive
    Server/Communication SoC.
 
  - TI adds support for J721s2, a new automotive SoC in the K3
    family.
 
  - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
    generation following their popular MT76xx series. Only basic
    support is added for now.
 
  - NXP i.MX8 ULP8 is a new low-power variant of the widespread
    i.MX8 series.
 
  - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
    we have supported for a long time.
 
 New boards with the existing SoCs include
 
  - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
 
  - AT91/SAMA5 based evaluation board
 
  - NXP gains twenty new development and industrial boards for their
    i.MX and Layerscape SoCs
 
  - Intel IXP4xx now supports the final two machines in device tree
    that were previously only supported in old style board files.
 
  - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
    while MT8183 is used in the Acer Chromebook 314.
 
  - Qualcomm gains support for the reference machines using the two
    new SoCs, plus a number of Chromebook variants and phones based
    on the Snapdragon 7c, 845 and 888 SoCs, including various
    Sony Xperia devices and the Microsoft Surface Duo 2.
 
  - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
 
  - Tegra now boots various older Android devices based on 32-bit
    chips out of the box, including a number of ASUS Transformer
    tablets.
    There is also a new Jetson AGX Orin developer kit.
 
  - Apple support adds the missing device trees for all the remaining
    M1 Macbook and iMac variants, though not yet the M1 Pro/Max
    versions.
 
  - Allwinner now supports another version of the Tanix TX6 set-top
    box based on the H6 SoC.

Pull ARM SoC devicetree updates from Arnd Bergmann:
 "As usual, this is the bulk of the updates for the SoC tree, adding
  more devices to existing files, addressing issues from ever improving
  automated checking, and fixing minor issues.

  The most interesting bits as usual are the new platforms. All the
  newly supported SoCs belong into existing families this time:

   - Qualcomm gets support for two newly announced platforms, both of
     which can now work in production environments: the SDX65 5G modem
     that can run a minimal Linux on its Cortex-A7 core, and the
     Snapdragon 8 Gen 1, their latest high-end phone SoC.

   - Renesas adds support for R-Car S4-8, the most recent automotive
     Server/Communication SoC.

   - TI adds support for J721s2, a new automotive SoC in the K3 family.

   - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
     generation following their popular MT76xx series. Only basic
     support is added for now.

   - NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8
     series.

   - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we
     have supported for a long time.

  New boards with the existing SoCs include

   - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers

   - AT91/SAMA5 based evaluation board

   - NXP gains twenty new development and industrial boards for their
     i.MX and Layerscape SoCs

   - Intel IXP4xx now supports the final two machines in device tree
     that were previously only supported in old style board files.

   - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while
     MT8183 is used in the Acer Chromebook 314.

   - Qualcomm gains support for the reference machines using the two new
     SoCs, plus a number of Chromebook variants and phones based on the
     Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia
     devices and the Microsoft Surface Duo 2.

   - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.

   - Tegra now boots various older Android devices based on 32-bit chips
     out of the box, including a number of ASUS Transformer tablets.

     There is also a new Jetson AGX Orin developer kit.

   - Apple support adds the missing device trees for all the remaining
     M1 Macbook and iMac variants, though not yet the M1 Pro/Max
     versions.

   - Allwinner now supports another version of the Tanix TX6 set-top box
     based on the H6 SoC.

   - Broadcom gains support for the Netgear RAXE500 Wireless router
     based on BCM4908"
