tools/perf: Map the ID values with register names

2016-04-21T13:33:00+00:00

Map ID values with corresponding register names. These names are then
displayed when user issues perf record with the -I option
followed by perf report/script with -D option.

To test this patchset, Eg:

  $ perf record -I ls   # record machine state at interrupt
  $ perf script -D      # read the perf.data file

Sample output obtained for this patch / output looks like as follows:

perf tools: Build syscall table .c header from kernel's syscall_64.tbl

2016-04-08T12:58:14+00:00

We used libaudit to map ids to syscall names and vice-versa, but that
imposes a delay in supporting new syscalls, having to wait for libaudit
to get those new syscalls on its tables.

To remove that delay, for x86_64 initially, grab a copy of
arch/x86/entry/syscalls/syscall_64.tbl and use it to generate those
tables.

Syscalls currently not available in audit-libs:

  # trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd
  Error:	Invalid syscall copy_file_range, membarrier, mlock2, pread64, pwrite64, timerfd_create, userfaultfd
  Hint:	try 'perf list syscalls:sys_enter_*'
  Hint:	and: 'man syscalls'
  #

With this patch:

  # trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd
    8505.733 ( 0.010 ms): gnome-shell/2519 timerfd_create(flags: 524288) = 36

perf probe: Check if dwarf_getlocations() is available

2016-04-06T13:44:28+00:00

If not, tell the user that:

  config/Makefile:273: Old libdw.h, finding variables at given 'perf probe' point will not work, install elfutils-devel/libdw-dev >= 0.157

And return -ENOTSUPP in die_get_var_range(), failing features that
need it, like the one pointed out above.

This fixes the build on older systems, such as Ubuntu 12.04.5.

perf build: Remove all condition feature check {C,LD}FLAGS

2016-01-29T17:47:52+00:00

'make feature-dump' should give a stable result, so even 'NO_SOMETHING=1'
is given (for babeltrace, if LIBBABELTRACE=1 is not given), we should
try to detect those feature and {C,LD}FLAGS. Build or not should be
controled independent.
