perf config: Add perf_home_perfconfig function
Factor out the perf_home_perfconfig, that looks for .perfconfig in home directory including check for PERF_CONFIG_NOGLOBAL and for proper permission.

perf debug: Add debug_set_display_time function
Allow to display time in perf debug output via new
debug_set_display_time function.
It will be used in perf daemon command to get verbose output into log
file.
The debug time format is:

perf mem: Clean up output format
Now, "--phys-data" is the only option which impacts the output format. A simple "if else" is enough to handle the option. But there will be more options added, e.g. "--data-page-size", which also impact the output format. The code will become too complex to be maintained. Divide the big printf into several small pieces. Output the specific piece only if the related option is applied. No functional change.

perf cs-etm: Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0
Replace the OCSD_INSTR switch statement with an if to fix compilation error about unhandled values and avoid this issue again in the future. Add new OCSD_GEN_TRC_ELEM_SYNC_MARKER and OCSD_GEN_TRC_ELEM_MEMTRANS enum values to fix unhandled value compilation error. Currently they are ignored.

perf stat: Enable counting events for BPF programs
Introduce 'perf stat -b' option, which counts events for BPF programs, like:
[root@localhost ~]# ~/perf stat -e ref-cycles,cycles -b 254 -I 1000
1.487903822 115,200 ref-cycles
1.487903822 86,012 cycles
2.489147029 80,560 ref-cycles
2.489147029 73,784 cycles
3.490341825 60,720 ref-cycles
3.490341825 37,797 cycles
4.491540887 37,120 ref-cycles
4.491540887 31,963 cycles
The example above counts 'cycles' and 'ref-cycles' of BPF program of id
254. This is similar to bpftool-prog-profile command, but more
flexible.
'perf stat -b' creates per-cpu perf_event and loads fentry/fexit BPF
programs (monitor-progs) to the target BPF program (target-prog). The
monitor-progs read perf_event before and after the target-prog, and
aggregate the difference in a BPF map. Then the user space reads data
from these maps.
A new 'struct bpf_counter' is introduced to provide a common interface
that uses BPF programs/maps to count perf events.
Committer notes:
Removed all but bpf_counter.h includes from evsel.h, not needed at all.
Also BPF map lookups for PERCPU_ARRAYs need to have as its value receive
buffer passed to the kernel libbpf_num_possible_cpus() entries, not
evsel__nr_cpus(evsel), as the former uses
/sys/devices/system/cpu/possible while the later uses
/sys/devices/system/cpu/online, which may be less than the 'possible'
number making the bpf map lookup overwrite memory and cause hard to
debug memory corruption.
We need to continue using evsel__nr_cpus(evsel) when accessing the
perf_counts array tho, not to overwrite another are of memory :-)

BPF programs are useful in perf to profile BPF programs. BPF skeleton is by far the easiest way to write BPF tools. Enable building BPF skeletons in util/bpf_skel. A dummy bpf skeleton is added. More bpf skeletons will be added for different use cases.

perf record: Add --buildid-mmap option to enable PERF_RECORD_MMAP2's build id
Add --buildid-mmap option to enable build id in PERF_RECORD_MMAP2 events.
It will only work if there's kernel support for that and it disables
build id cache (implies --no-buildid).
It's also possible to enable it permanently via config option in
~/.perfconfig file:
[record]
build-id=mmap
Also added build_id bit in the verbose output for perf_event_attr:
# perf record --buildid-mmap -vv
...
perf_event_attr:
type 1
size 120
...
build_id 1
Adding also missing text_poke bit.
Committer testing:
$ perf record -h build
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
-B, --no-buildid do not collect buildids in perf.data
-N, --no-buildid-cache
do not update the buildid cache
--buildid-all Record build-id of all DSOs regardless of hits
--buildid-mmap Record build-id in map events
$
$ perf record --buildid-mmap sleep 1
Failed: no support to record build id in mmap events, update your kernel.

After adding the needed kernel bits in a test kernel:
$ perf record -vv --buildid-mmap sleep 1 |& grep -m1 build

perf probe: Fixup Arm64 SDT arguments
Arm64 ELF section '.note.stapsdt' uses string format "-4@[sp, NUM]" if the probe is to access data in stack, e.g. below is an example for dumping Arm64 ELF file and shows the argument format: Arguments: -4@[sp, 12] -4@[sp, 8] -4@[sp, 4] Comparing against other archs' argument format, Arm64's argument introduces an extra space character in the middle of square brackets, due to argv_split() uses space as splitter, the argument is wrongly divided into two items. To support Arm64 SDT, this patch fixes up for this case, if any item contains sub string "[sp", concatenates the two continuous items. And adds the detailed explaination in comment.

drm/amd/display: avoid uninitialized variable warning
clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.
This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.
So just initialize 'val' to zero to avoid the issue.

perf tools changes for v5.11, 2nd batch:
- Refactor 'perf stat' per CPU/socket/die/thread aggregation fixing use
cases in ARM machines.
- Fix memory leak when synthesizing SDT probes in 'perf probe'.
- Update kernel header copies related to KVM, epol_pwait. msr-index and
powerpc and s390 syscall tables.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
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.
