<content type='text'>
The original Makefile uses "uname -m" to determine ARCH.
This causes problem on x86 when compile perf tool on 32 bit
userspace with a 64 bit kernel.

 bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages:
 bench/../../../arch/x86/lib/memcpy_64.S:28: Error: bad register name `%rdi'

This is because "uname -m" returns x86_64 and memcpy_64.S is
included in 32 bit build.

Fix the following build error:

 In file included from util/evsel.h:10,

 util/hist.h:106:18: error: newt.h: No such file or directory
 error: command 'x86_64-pc-linux-gnu-gcc' failed with exit status 1
 make: *** [python/perf.so] Error 1

by passing BASIC_CFLAGS to setup.py. BASIC_CFLAGS variable contains
the -DNO_NEWT_SUPPORT switch which prevents building python c
extension with newt.

<title>perf tools: Makefile: Remove various and sundry cruft</title>

This commit squashes several commits that remove:

 unnecessary uname calls
 `sh -c'
 BUILT_INS and QUIET_BUILT_IN

    They have no effect, and the `fixup-builtins' and `check-builtins.sh'
    scripts don't even exist.

 RUNTIME_PREFIX

    It's currently never anything but unset, and it's apparently
    only meaningful when Microsoft Windows is the operating system
    (according to the source for git).

 TEST_PROGRAMS
 EXTRA_PROGRAMS
 unused SHELL_PATH_SQ portions
 unused test for V=2
 useless exports

    Only when `V' is undefined (that is, only when the value of `V'
    is empty) is `export V' performed, which just has the effect of
    placing the empty-valued variable `V' in the environment.

    The only other script to make use of `V' is `Documentation/Makefile',
    which only checks whether `V' is undefined (that is, whether the value
    of `V' is empty); hence, the `export V' has no effect whatsoever.

    Similarly, `export QUIET_GEN' is useless because it will only have
    a non-empty value when `V' has an empty-value, and when `V' has
    an empty-value, `QUIET_GEN' is always explicitly set in every
    script in which it is used.

    `DESTDIR' is only ever defined by the user via the environment
    or the command line, both of which are automatically exported
    to sub-make processes. Furthermore, no non-make sub-scripts
    make use of `DESTDIR' as an environment variable.

    No other scripts use `perfexec_instdir'.

 unused QUIET_SUBDIR{0,1}
 TAR and RPMBUILD
 PTHREAD_LIBS
 Maintainer's dist rules and commands
 distclean target
 Test suite coverage testing
 PRINT_DIR and NO_SUBDIR
 `configure' target
 NO_CURL
 @@PERF_VERSION@@ substitution

    Without the sed command, all of the rule's commands can be reduced
    to a single line that copies a file and sets the permissions properly
    in the process.

 `make test' echo line
 template_instdir
 PERF-BUILD-OPTIONS
 double-colon rules

    The use of double-colon rules seems misguided or vestigial git.

 Essentially hard-coded $(SCRIPTS) expansion

The ui operations so far were used by just one thread, but 'perf top
--tui' now has two threads updating the screen, so we need to use a
mutex to avoid garbling the screen.

The ui operations so far were used by just one thread, but 'perf top
--tui' now has two threads updating the screen, so we need to use a
mutex to avoid garbling the screen.

This patch adds the ability to filter monitoring based on container groups
(cgroups) for both perf stat and perf record. It is possible to monitor
multiple cgroup in parallel. There is one cgroup per event. The cgroups to
monitor are passed via a new -G option followed by a comma separated list of
cgroup names.

The cgroup filesystem has to be mounted. Given a cgroup name, the perf tool
finds the corresponding directory in the cgroup filesystem and opens it. It
then passes that file descriptor to the kernel.

Example:

$ perf stat -B -a -e cycles:u,cycles:u,cycles:u -G test1,,test2 -- sleep 1
 Performance counter stats for 'sleep 1':

      2,368,667,414  cycles                   test1
      2,369,661,459  cycles
      &lt;not counted&gt;  cycles                   test2

        1.001856890  seconds time elapsed
