perf tools: Add Intel PT instruction decoder

2015-08-17T14:11:36+00:00

Add support for decoding instructions for Intel Processor Trace.  The
kernel x86 instruction decoder is copied for this.

This essentially provides intel_pt_get_insn() which takes a binary
buffer, uses the kernel's x86 instruction decoder to get details of the
instruction and then categorizes it for consumption by an Intel PT
decoder.

perf build: Use FEATURE-DUMP instead of PERF-FEATURES in the .gitignore file

2015-03-20T20:49:51+00:00

Since commit 4ae61202b31c ("perf build: Rename PERF-FEATURES into
FEATURE-DUMP") renames PERF-FEATURES into FEATURE-DUMP, the .gitignore
file should also do this thing for consistency.

perf tools: Add perf-with-kcore script

2014-09-17T20:08:08+00:00

Decoding an Intel PT trace of the kernel requires an accurate kernel
object image.  This is provided by making a copy of kcore.  However the
copy needs to be made under the same conditions as the original
recording, and then it needs to be associated with the perf.data file.
The perf-with-kcore script does that.

The script also checks the permissions on the buildid cache and can be
used to fix them.  That is needed for distributions where root does not
have a home directory and consequently writes to the same buildid cache
as the user, resulting in cached files that the user does not have
access to.

Example:

$ ./perf-with-kcore
Usage: perf-with-kcore   [ [ -- ]]
        can be record, script, report or inject
   or: perf-with-kcore fix_buildid_cache_permissions
$ ./perf-with-kcore record pt_uname -e intel_pt// -- uname

perf tools: Makefile: Remove various and sundry cruft

2011-02-18T09:43:06+00:00

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
