2c3e962911 perf trace beautify ioctl: Beautify sound ioctl's 'cmd' arg 
This time we try a new approach, using a copy of uapi/sound/asound.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.

This way either the sound developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.

E.g.:

  # perf trace -p 22084 -e ioctl 2>&1 | head -5
     0.000 ( 0.068 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0
     0.344 ( 0.041 ms): alsa-sink-ALC3/22084 ioctl(fd: 46</dev/snd/controlC1>, cmd: SNDRV_CTL_ELEM_READ, arg: 0x7fe764018ee0) = 0

ef9811f093 perf trace beauty ioctl: Beautify DRM ioctl cmds 
This time we try a new approach, using uapi/drm/ copies of drm.h and
i915_drm.h we auto generate the string tables, then include it in the
ioctl cmd beautifier.

This way either the DRM developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.

Either way the time from a new command being added to when 'perf trace'
gets to know it is greatly shortened, for instance:

  # strace -p 22401 -e ioctl

1cc47f2d46 perf trace beauty ioctl: Improve 'cmd' beautifier 
By using the _IOC_(DIR,NR,TYPE,SIZE) macros to lookup a 'type' keyed
table that then gets indexed by 'nr', falling back to a notation similar
to the one used by 'strace', only more compact, i.e.:

   474.356 ( 0.007 ms): gnome-shell/22401 ioctl(fd: 8</dev/dri/card0>, cmd: (READ|WRITE, 0x64, 0xae, 0x1c), arg: 0x7ffc934f7880) = 0
   474.369 ( 0.053 ms): gnome-shell/22401 ioctl(fd: 8</dev/dri/card0>, cmd: (READ|WRITE, 0x64, 0xb0, 0x18), arg: 0x7ffc934f77d0) = 0
   505.055 ( 0.014 ms): gnome-shell/22401 ioctl(fd: 8</dev/dri/card0>, cmd: (READ|WRITE, 0x64, 0xaf, 0x4), arg: 0x7ffc934f741c) = 0

This also moves it out of builtin-trace.c and into trace/beauty/ioctl.c
to better compartimentalize all these formatters.

The 'parent_tidptr', 'child_tidptr' and 'tls' arguments to the 'clone'

them when those aren't there.

Need to improve the formatting of the second return, to the child, this

^C#

We'll also have to fix the argument ordering in different arches,
probably having multiple syscall_fmt entries with each possible order
and then use perf_evsel__env_arch() (if dealing with a perf.data file)
or the current system info, for live sessions.

b239ad28a8 perf beauty open: Detach the syscall_arg agnostic bits from the flags formatter 
We may want to use this in other contexts, like when formatting the
return of fcntl(fd, F_GETFL).

Make it have the following signature, so that we can set the formatter
for the return argument while processing the arguments of a syscall, as
fcntl, for instance, may return fds, flags, etc, so need different
return value formatters:

	size_t formatter(unsigned long value, char *bf, size_t size);

This gets so detached from 'perf trace' internals that we may well get
all these and move to a tools/lib/syscall_beauty/ library at some point
and use it in other tools/ living utilities.

fd5cead23f perf trace: Beautify statx syscall 'flag' and 'mask' arguments 
To test it, build samples/statx/test_statx, which I did as:

  $ make headers_install
  $ cc -I ~/git/linux/usr/include samples/statx/test-statx.c -o /tmp/statx

And then use perf trace on it:

  # perf trace -e statx /tmp/statx /etc/passwd
  statx(/etc/passwd) = 0
  results=7ff
    Size: 3496            Blocks: 8          IO Block: 4096    regular file

  #

Adding a probe to get the filename collected as well:

  # perf probe 'vfs_getname=getname_flags:72 pathname=result->name:string'
  Added new event:
    probe:vfs_getname    (on getname_flags:72 with pathname=result->name:string)

  You can now use it in all perf tools, such as:

	  perf record -e probe:vfs_getname -aR sleep 1

  # trace --no-inherit -e statx /tmp/statx -D -O /etc/passwd > /dev/null
     0.169 ( 0.007 ms): statx(dfd: CWD, filename: /etc/passwd, flags: SYMLINK_NOFOLLOW|STATX_DONT_SYNC, mask: BTIME, buffer: 0x7ffda9bf50f0) = 0
  #

Same technique could be used to collect and beautify the result put in
the 'buffer' argument.

Finally do a system wide 'perf trace' session looking for any use of statx,
then run the test proggie with various flags:

  # trace -e statx
   16612.967 ( 0.028 ms): statx/4562 statx(dfd: CWD, filename: /tmp/statx, flags: SYMLINK_NOFOLLOW, mask: TYPE|MODE|NLINK|UID|GID|ATIME|MTIME|CTIME|INO|SIZE|BLOCKS|BTIME, buffer: 0x7ffef195d660) = 0
   33064.447 ( 0.011 ms): statx/4569 statx(dfd: CWD, filename: /tmp/statx, flags: SYMLINK_NOFOLLOW|STATX_FORCE_SYNC, mask: TYPE|MODE|NLINK|UID|GID|ATIME|MTIME|CTIME|INO|SIZE|BLOCKS|BTIME, buffer: 0x7ffc5484c790) = 0
   36050.891 ( 0.023 ms): statx/4576 statx(dfd: CWD, filename: /tmp/statx, flags: SYMLINK_NOFOLLOW, mask: BTIME, buffer: 0x7ffeb18b66e0) = 0
   38039.889 ( 0.023 ms): statx/4584 statx(dfd: CWD, filename: /tmp/statx, flags: SYMLINK_NOFOLLOW, mask: TYPE|MODE|NLINK|UID|GID|ATIME|MTIME|CTIME|INO|SIZE|BLOCKS|BTIME, buffer: 0x7fff1db0ea90) = 0
  ^C#

This one also starts moving the beautifiers from files directly included
in builtin-trace.c to separate objects + a beauty.h header with
prototypes, so that we can add test cases in tools/perf/tests/ to fire
syscalls with various arguments and then get them intercepted as
syscalls:sys_enter_foo or raw_syscalls:sys_enter + sys_exit to then
format and check that the formatted output is the one we expect.

Those beautifiers need to make sure they include what they reference,
as changes in builtin-trace.c may end up removing needed stuff, like
when undefining _GNU_SOURCE.

073e5fca53 perf trace: Read thread's COMM from /proc when not set 
We get notifications for threads that gets created while we're tracing,
but for preexisting threads we may end not having synthesized them, like
when tracing a 'perf trace' session that will use '--pid' to trace some
other thread.

And besides we should probably stop synthesizing those records and
instead read thread information in a lazy way, i.e. just when we need,
like done in this patch:

Now the 'pid_t' argument in 'perf_event_open' gets translated to a COMM:

  # perf trace -e perf_event_open perf stat -e cycles -p 31601
     0.027 ( 0.027 ms): perf/23393 perf_event_open(attr_uptr: 0x2fdd0d8, pid: 31601 (abrt-dump-journ), cpu: -1, group_fd: -1, flags: FD_CLOEXEC)
                                                                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
= 3
^C

And in other syscalls containing pid_t without thread->comm_set at the
time of the formatting.
