tools: Copy lib/hweight.c from the kernel sources

2015-07-09T19:29:56+00:00

Instead of accessing it directly, as it uses EXPORT_SYMBOL, that has
no meaning in tools/perf and because we removed the stubs for it, i.e.
we removed the tools/include/linux/export.h file.

This fixes the build for the detached tarball sources cases and removes
one more source of entanglement with the kernel sources.

tools: Copy lib/rbtree.c to tools/lib/

2015-07-06T01:48:21+00:00

So that we can remove kernel specific stuff we've been stubbing out via
a tools/include/linux/export.h that gets removed in this patch and to
avoid breakages in the future like the one fixed recently where
rcupdate.h started being used in rbtree.h.

perf stat: Move shadow stat counters into separate object

2015-06-08T13:30:31+00:00

Separating shadow counters code into separate object as a cleanup, but
mainly for upcomming changes, so could use it from script command
context.

perf tools: Move branch option parsing to own file

2015-05-28T00:02:17+00:00

.. to allow sharing between builtin-record and builtin-top later.  No
code changes, just moved code.

perf tools: Add build option NO_AUXTRACE to exclude AUX area tracing

2015-05-05T21:12:53+00:00

Add build option NO_AUXTRACE to exclude compiling support for AUX area
tracing. Support for both recording and processing is excluded and by
implication any future additions such as Intel PT and Intel BTS will
also not be compiled in with this option.

perf tools: Fix bison-related build failure on CentOS 6

2015-05-04T15:43:52+00:00

The YYLTYPE_IS_TRIVIAL is defined in the Build file, but unlike
pmu-bison.c, gcc complained about it for parse-events-bison.c:

    CC       util/parse-events-bison.o
  In file included from util/parse-events.y:16:
  util/parse-events-bison.h:101:1: error: "YYLTYPE_IS_TRIVIAL" redefined
  : error: this is the location of the previous definition
  make[3]: *** [util/parse-events-bison.o] Error 1

Comments from Jiri Olsa:

"Reason is the parse error handling that was added just recently: it
adds YYLTYPE type (which is not present in pmu-bison.h), so
YYLTYPE_IS_TRIVIAL gets redefined, which is ok in F20 that handle the
error via '-w' option, but it's not ok for RHEL6 where the '-w' does not
work for this kind of error."

perf evlist: Add support for mmapping an AUX area buffer

2015-04-29T13:37:50+00:00

This patch supports the addition to the kernel of AUX area buffers that
can be mmapped separately from the perf-events buffer.

The AUX buffer can be configured to contain hardware-produced trace
information. The first implementation will support Intel BTS and Intel
PT.

One auxtrace buffer is mmapped per perf-events buffer.  If the requested
auxtrace buffer size is zero, which it will be until further support is
added, then no auxtrace mmapping is attempted.

perf tools: Add lzma decompression support for kernel module

2015-03-21T17:53:40+00:00

In short, Fedora compresses kernel modules now (since version 21) with
lzma compression.

Adding lzma decompress support into the dso.c:compressions array
introduced by Namhyung earlier.
