  perf trace: Beautify statx syscall 'flag' and 'mask' arguments (2017-03-31 
14:42:31 -0300)


perf/core improvements and fixes:

New features:

- Beautify the statx syscall arguments in 'perf trace' (Arnaldo Carvalho de 
Melo)

e.g.:

  System wide strace like session:

  # trace -e statx
   16612.967 ( 0.028 ms): statx/4562 statx(dfd: CWD, filename: /tmp/statx, 
flags: SYMLINK_NOFOLLOW, mask:

0x7ffef195d660) = 0
   36050.891 ( 0.007 ms): statx/4576 statx(dfd: CWD, filename: /etc/passwd, 
flags: SYMLINK_NOFOLLOW|STATX_DONT_SYNC, mask: BTIME, buffer: 0x7ffda9bf50f0) = 0
  ^C#

User visible:

- Handle unpaired raw_syscalls:sys_exit events in 'perf trace', i.e. we
  shouldn't try to calculate duration or print the timestamp for a missing
  matching raw_syscalls:sys_enter (Arnaldo Carvalho de Melo)

- Do not print "cycles: 0" in perf report LBR lines in platforms not
  supporting 'cycles', such as Intel's Broadwell (Jin Yao)

- Handle missing $HOME env var (Jiri Olsa)

- Map 8-bit registers (al, bl, etc), not supported in uprobes_events, to
  the next best thing (ax, bx, etc) supported (Ravi Bangoria)

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

For this specific pull request the samples/bpf/ was disabled, as 'make 
headers_install'
is failing with the following error, in this case in fedora:rawhide:

perf/core improvements:

Infrastructure:

- Make 'perf trace' auto-attach fd->name and ptr->name beautifiers based

  'const char * (path,pathname,filename)' will use the fd->name beautifier
  (vfs_getname perf probe, if in place) and the 'fd->name' (vfs_getname

Infrastructure:

I did not write that.

I think making the feature tests parallel would be enough to 
speed it all up - caching brings in a new set of problems. The 
tests are mostly independent and the feature test makefile rules 
could be parallelized like the object file rules.

hey, we build perf much faster than autoconf's 'configure'

Btw., there's another thing that would be nice in addition to 
simplifying the PERF-VERSION-GEN script: to be able to run the 
CHK tests in parallel, like the object file runes.

Right now the CHK tests are serialized and they take several 
seconds to build and run. A parallel make rule would reduce
that to about a second I think.

Thanks,

   These are really useful: there used to be a couple of 
   seconds of wait time at the beginning of every perf build - 
   these are now nicely explained with the various CHK entries.
  
  The optimal way, I guess, would be to have some cache file 
  with the results of such feature tests, that would be created 
  and then used till the build fails using its findings, which 
  would trigger a new feature check round, followed by an 
  automatic rebuild.
  
  That would be tricky because we would have to have an 
  automated way of discovering if the build failed due to 
  missing packages or if it failed due to some ordinary coding 
  mistake.
 
 The feature tests aren't a big problem right now - but making 
 it *visible* is really useful. It also tells us which feature 
 test fails, etc.

Don't know why it takes a significant number of seconds to compile
this file. It did not use to be like that a few revisions back. It takes
about 8 seconds on my OC'd IVB (> 4GHz).  I don't see much code
in that file.

The feature tests aren't a big problem right now - but making it

 Kudos to Jiri who did the real work!


 PERF-VERSION-GEN and specifically the git commands are the cause of more
 delay than the config checks, especially when doing the build in a VM
 with the kernel source on an NFS mount.

 And I see a strange delay when compiling builtin-sched.o.  After
 building perf tools, I deleted builtin-{sched,test,script}.o to rebuild
 the only since they are largest ones.

Yes, I see that delay on copiling builtin-sched.c on my IVB system.
Don't know why it takes a significant number of seconds to compile
this file. It did not use to be like that a few revisions back. It takes
about 8 seconds on my OC'd IVB ( 4GHz).  I don't see much code
in that file.

   namhyung@leonhard:perf$ ls -lS *.c | head -3
   -rw-r--r-- 1 namhyung namhyung 45522 2012-10-27 00:20 builtin-sched.c
   -rw-r--r-- 1 namhyung namhyung 36372 2012-10-27 00:20 builtin-test.c
   -rw-r--r-- 1 namhyung namhyung 3 2012-10-27 00:20 builtin-script.c

   namhyung@leonhard:perf$ rm builtin-{sched,test,script}.o


 And then building each file with time command shows this:

   namhyung@leonhard:perf$ time make builtin-script.o  /dev/null

   real  0m4.577s
   user  0m2.755s
   sys   0m1.655s

   namhyung@leonhard:perf$ time make builtin-test.o  /dev/null

   real  0m4.486s
   user  0m2.707s
   sys   0m1.658s

   namhyung@leonhard:perf$ time make builtin-sched.o  /dev/null

   real  0m16.936s
   user  0m15.157s
   sys   0m1.635s

 You can see it easily when building perf without -j option. But I have
 no idea why it takes so long..

 Thanks,
 Namhyung

The optimal way, I guess, would be to have some cache file with the
results of such feature tests, that would be created and then used till
the build fails using its findings, which would trigger a new feature
check round, followed by an automatic rebuild.

That would be tricky because we would have to have an automated way of
discovering if the build failed due to missing packages or if it failed
due to some ordinary coding mistake.

And I see a strange delay when compiling builtin-sched.o.  After
building perf tools, I deleted builtin-{sched,test,script}.o to rebuild
the only since they are largest ones.

  namhyung@leonhard:perf$ ls -lS *.c | head -3
  -rw-r--r-- 1 namhyung namhyung 45522 2012-10-27 00:20 builtin-sched.c

  -rw-r--r-- 1 namhyung namhyung 3 2012-10-27 00:20 builtin-script.c

  namhyung@leonhard:perf$ rm builtin-{sched,test,script}.o


And then building each file with time command shows this:

  namhyung@leonhard:perf$ time make builtin-script.o &> /dev/null

  real  0m4.577s
  user  0m2.755s
  sys   0m1.655s

  namhyung@leonhard:perf$ time make builtin-test.o &> /dev/null

  real  0m16.936s

You can see it easily when building perf without -j option. But I have
no idea why it takes so long..

These are really useful: there used to be a couple of seconds of

nicely explained with the various CHK entries.


PERF-VERSION-GEN and specifically the git commands are the cause of more

Kudos to Jiri who did the real work!

 
 PERF-VERSION-GEN and specifically the git commands are the cause of more

 with the kernel source on an NFS mount.

And I see a strange delay when compiling builtin-sched.o.  After
building perf tools, I deleted builtin-{sched,test,script}.o to rebuild
the only since they are largest ones.

  namhyung@leonhard:perf$ ls -lS *.c | head -3
  -rw-r--r-- 1 namhyung namhyung 45522 2012-10-27 00:20 builtin-sched.c
  -rw-r--r-- 1 namhyung namhyung 36372 2012-10-27 00:20 builtin-test.c
  -rw-r--r-- 1 namhyung namhyung 3 2012-10-27 00:20 builtin-script.c

  namhyung@leonhard:perf$ rm builtin-{sched,test,script}.o


And then building each file with time command shows this:

  namhyung@leonhard:perf$ time make builtin-script.o  /dev/null

  real  0m4.577s
  user  0m2.755s
  sys   0m1.655s

  namhyung@leonhard:perf$ time make builtin-test.o  /dev/null

  real  0m4.486s
  user  0m2.707s
  sys   0m1.658s

  namhyung@leonhard:perf$ time make builtin-sched.o  /dev/null

  real  0m16.936s
  user  0m15.157s
  sys   0m1.635s

You can see it easily when building perf without -j option. But I have
no idea why it takes so long..

Thanks,
Namhyung

 You can see it easily when building perf without -j option. But I have
 no idea why it takes so long..

Well, you can trace that workload with perf itself, no, and see the
hotspots.

Right, perf'ing perf is a favourite pastime, right?

 These are really useful: there used to be a couple of seconds of 
 wait time at the beginning of every perf build - these are now 
 nicely explained with the various CHK entries.

The optimal way, I guess, would be to have some cache file with the
results of such feature tests, that would be created and then used till
the build fails using its findings, which would trigger a new feature
check round, followed by an automatic rebuild.

That would be tricky because we would have to have an automated way of
discovering if the build failed due to missing packages or if it failed
due to some ordinary coding mistake.
