ec49230cf6 perf debug: Expose debug file
Some dumping call backs need to be passed a FILE*. Expose debug file
via an accessor API for a consistent way to do this. Catch the
unlikely failure of it not being set. Switch two cases where stderr
was being used instead of debug_file.

8d5847a617 perf maps: Add remove maps function to remove a map based on callback
Removing maps wasn't being done under the write lock. Similar to
maps__for_each_map(), iterate the entries but in this case remove the
entry based on the result of the callback. If an entry was removed
then maps_by_name() also needs updating, so add missed flush.

In dso__load_kcore(), the test of map to save would always be false with
REFCNT_CHECKING because of a missing RC_CHK_ACCESS/RC_CHK_EQUAL.

e43c64c971 perf archive: Add new option '--unpack' to expand tarballs
Archives generated by the command 'perf archive' have to be unpacked
manually.

Following the addition of option '--all' now there also exist a nested
structure of tars, and after further discussion with Red Hat Global
Support Services, they found a feature correctly unpacking archives of
'perf archive' convenient.

Option '--unpack' of 'perf archive' unpacks archives generated by the
command 'perf archive' as well as archives generated when used with
option '--all'.

The 'perf.data' file is placed in the current directory, while debug
symbols are unpacked in '~/.debug' directory. A tar filename can be
passed as an argument, and if not provided the command tries to find a
viable perf.tar file for unpacking.

624dda101e perf archive: Add new option '--all' to pack perf.data with DSOs
'perf archive' has limited functionality and people from Red Hat Global
Support Services sent a request for a new feature that would pack
perf.data file together with an archive with debug symbols created by
the command 'perf archive' as customers were being confused and often
would forget to send perf.data file with the debug symbols.

With this patch 'perf archive' now accepts an option '--all' that
generates archive 'perf.all-hostname-date-time.tar.bz2' that holds file
'perf.data' and a sub-tar 'perf.symbols.tar.bz2' with debug symbols. The
functionality of the command 'perf archive' was not changed.

Committer testing:

Run 'perf record' on a Intel 14900K machine, hybrid:

  root@number:~# perf record -a sleep 5s
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 4.006 MB perf.data (15427 samples) ]
  root@number:~# perf archive --all
  Now please run:

  $ tar xvf perf.all-number-20231219-104854.tar.bz2 && tar xvf perf.symbols.tar.bz2 -C ~/.debug

  wherever you need to run 'perf report' on.

The macro maps__for_each_entry is error prone as it doesn't require
holding the maps lock.

Add a new function that iterates the maps holding the read lock.

Convert maps__find_symbol_by_name() and maps__fprintf() to use callbacks,
the latter being an example of where the read lock wasn't being held.

0b4b785d1f perf evlist: Move event attributes to after the / when uniquefying using the PMU name
When turning an event with attributes to the format including the PMU we
need to move the "event:attributes" format to "event/attributes/" so
that we can copy the event displayed and use it in the command line,
i.e. in 'perf top' we had:

 1K cpu_atom/cycles:P/
 11K cpu_core/cycles:P/

If I try to use that on the command line:

  # perf top -e cpu_atom/cycles:P/
  event syntax error: 'cpu_atom/cycles:P/'
                                \___ Bad event or PMU

a61f89bf76 perf top: Uniform the event name for the hybrid machine
It's hard to distinguish the default cycles events among hybrid PMUs.
For example,

  $ perf top
  Available samples
  385 cycles:P
  903 cycles:P

The other tool, e.g., perf record, uniforms the event name and adds the
hybrid PMU name before opening the event. So the events can be easily
distinguished. Apply the same methodology for the perf top as well.

The evlist__uniquify_name() will be invoked by both record and top.
Move it to util/evlist.c

With the patch:

  $ perf top
  Available samples
  148 cpu_atom/cycles:P/
  1K cpu_core/cycles:P/

5fa695e7da perf top: Use evsel's cpus to replace user_requested_cpus
perf top errors out on a hybrid machine
 $perf top

 Error:
 The cycles:P event is not supported.

The perf top expects that the "cycles" is collected on all CPUs in the
system. But for hybrid there is no single "cycles" event which can cover
all CPUs. Perf has to split it into two cycles events, e.g.,
cpu_core/cycles/ and cpu_atom/cycles/. Each event has its own CPU mask.
If a event is opened on the unsupported CPU. The open fails. That's the
reason of the above error out.

Perf should only open the cycles event on the corresponding CPU. The
commit ef91871c960e ("perf evlist: Propagate user CPU maps intersecting
core PMU maps") intersect the requested CPU map with the CPU map of the
PMU. Use the evsel's cpus to replace user_requested_cpus.

The evlist's threads are also propagated to the evsel's threads in
__perf_evlist__propagate_maps(). For a system-wide event, perf appends
a dummy event and assign it to the evsel's threads. For a per-thread
event, the evlist's thread_map is assigned to the evsel's threads. The
same as the other tools, e.g., perf record, using the evsel's threads
when opening an event.

4fb54994b2 perf unwind-libunwind: Fix base address for .eh_frame
The base address of a DSO mapping should start at the start of the file.
Usually DSOs are mapped from the pgoff 0 so it doesn't matter when it
uses the start of the map address.

But generated DSOs for JIT codes doesn't start from the 0 so it should
subtract the offset to calculate the .eh_frame table offsets correctly.

c966d23a35 perf unwind-libdw: Handle JIT-generated DSOs properly
Usually DSOs are mapped from the beginning of the file, so the base
address of the DSO can be calculated by map->start - map->pgoff.

However, JIT DSOs which are generated by `perf inject -j`, are mapped
only the code segment.  This makes unwind-libdw code confusing and
rejects processing unwinds in the JIT DSOs.  It should use the map
start address as base for them to fix the confusion.

Having two options confuses users who generally don't appreciate the
difference in PMUs. Keep all the options but make it so they all

1bc479d665 perf hisi-ptt: Fix one memory leakage in hisi_ptt_process_auxtrace_event()
ASan complains a memory leakage in hisi_ptt_process_auxtrace_event()
that the data buffer is not freed. Since currently we only support the
raw dump trace mode, the data buffer is used only within this function.
So fix this by freeing the data buffer before going out.

When dump the raw trace by `perf report -D` ASan reports a memory

9d03194a36 perf annotate: Introduce global annotation_options
The annotation options are to control the behavior of objdump and the
output.  It's basically used by 'perf annotate' but 'perf report' and
'perf top' can call it on TUI dynamically.

But it doesn't need to have a copy of annotation options in many places.

As most of the work is done in the util/annotate.c file, add a global
variable and set/use it instead of having their own copies.

0713ab3bd1 perf stat: Exit perf stat if parse groups fails
Metrics were added by a callback but commit a4b8cfcabb1d90ec ("perf
stat: Delay metric parsing") postponed this to allow optimizations based
on the CPU configuration.

In doing so it stopped errors in metric parsing from causing 'perf stat'
termination.

This change adds the termination for bad metric names back in.

Fixes: a4b8cfcabb1d90ec ("perf stat: Delay metric parsing")

01261d8a0f perf thread: Add missing RC_CHK_EQUAL
Comparing pointers without RC_CHK_ACCESS means the indirect object
will be compared rather than the underlying maps when REFCNT_CHECKING

9fa688ea34 perf map: Simplify map_ip/unmap_ip and make 'struct map' smaller
When mapping an IP it is either an identity mapping or a DSO relative
mapping, so a single bit is required in the struct to identify
this.

The current code uses function pointers, adding 2 pointers per map and
also pushing the size of a map beyond 1 cache line.

Switch to using a byte to identify the mapping type (as well as priv and
erange_warned), to avoid any masking.

Change struct maps's layout to avoid holes.

Before:
```
struct map {
        u64                        start;                /*     0     8 */
        u64                        end;                  /*     8     8 */
        _Bool                      erange_warned:1;      /*    16: 0  1 */
        _Bool                      priv:1;               /*    16: 1  1 */

        /* XXX 6 bits hole, try to pack */
        /* XXX 3 bytes hole, try to pack */

        u32                        prot;                 /*    20     4 */
        u64                        pgoff;                /*    24     8 */
        u64                        reloc;                /*    32     8 */
        u64                        (*map_ip)(const struct map  *, u64); /*    40     8 */
        u64                        (*unmap_ip)(const struct map  *, u64); /*    48     8 */
        struct dso *               dso;                  /*    56     8 */
        /* --- cacheline 1 boundary (64 bytes) --- */
        refcount_t                 refcnt;               /*    64     4 */
        u32                        flags;                /*    68     4 */

        /* size: 72, cachelines: 2, members: 12 */
        /* sum members: 68, holes: 1, sum holes: 3 */
        /* sum bitfield members: 2 bits, bit holes: 1, sum bit holes: 6 bits */
        /* last cacheline: 8 bytes */
};
```

After:
```
struct map {
        u64                        start;                /*     0     8 */
        u64                        end;                  /*     8     8 */
        u64                        pgoff;                /*    16     8 */
        u64                        reloc;                /*    24     8 */
        struct dso *               dso;                  /*    32     8 */
        refcount_t                 refcnt;               /*    40     4 */
        u32                        prot;                 /*    44     4 */
        u32                        flags;                /*    48     4 */
        enum mapping_type          mapping_type:8;       /*    52: 0  4 */

        /* Bitfield combined with next fields */

        _Bool                      erange_warned;        /*    53     1 */
        _Bool                      priv;                 /*    54     1 */

        /* size: 56, cachelines: 1, members: 11 */
        /* padding: 1 */
        /* last cacheline: 56 bytes */
};
