perf tools: Add missing headers in perf's MANIFEST

2016-01-08T15:48:40+00:00

These lost headers are found in arm64 cross buildings, failing to build
perf using tarballs generated using:

 $ make perf-targz-src-pkg

tools lib: Move find_next_bit.c to tools/lib/

2016-01-08T15:35:35+00:00

The commit that introduced it should've moved it to the same place, plus
the 'tools/' prefix, but instead moved it to a bogus tools/lib/util/
directory, being the only file there.

Move it to tools/lib/find_bit.c, picking the name for the file where
these routines live since:

 8f6f19dd5143 ("lib: move find_last_bit to lib/find_next_bit.c")

Next step is to make tools/lib/find_bit.c to differ from lib/find_bit.c
just in removing what is not used by tools/.

perf subcmd: Create subcmd library

2015-12-17T17:27:14+00:00

Move the subcommand-related files from perf to a new library named
libsubcmd.a.

Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to
'exec-cmd.*' to be consistent with the naming of all the other files.

tools: Adopt memdup() from tools/perf, moving it to tools/lib/string.c

2015-11-18T20:51:02+00:00

That will contain more string functions with counterparts, sometimes
verbatim copies, in the kernel.

perf tools: Make perf depend on libbpf

2015-10-28T15:48:12+00:00

By adding libbpf into perf's Makefile, this patch enables perf to build
libbpf if libelf is found and neither NO_LIBELF nor NO_LIBBPF is set.

The newly introduced code is similar to how libapi and libtraceevent
are wired into Makefile.perf.

MANIFEST is also updated for 'make perf-*-src-pkg'.

Append make_no_libbpf to tools/perf/tests/make.

The 'bpf' feature check is appended into default FEATURE_TESTS and
FEATURE_DISPLAY, so perf will check the API version of bpf in
/path/to/kernel/include/uapi/linux/bpf.h. Which should not fail except
when we are trying to port this code to an old kernel.

Error messages are also updated to notify users about the lack of BPF
support in 'perf record' if libelf is missing or the BPF API check
failed.

tools/lib/bpf is added to TAG_FOLDERS to allow us to navigate libbpf
files when working on perf using tools/perf/tags.

perf tools: Copy linux/filter.h to tools/include

2015-09-02T19:30:46+00:00

This patch copies filter.h from include/linux/kernel.h to
tools/include/linux/filter.h to enable other libraries to use macros in it,
like libbpf which will be introduced by further patches.

Currently, the filter.h copy only contains the useful macros needed by
libbpf for not introducing too much dependence.

tools/perf/MANIFEST is also updated for 'make perf-*-src-pkg'.

One change:
  The 'imm' field of BPF_EMIT_CALL becomes ((FUNC) - BPF_FUNC_unspec) to
  suit user space code generator.

We don't carry an export.h wrapper anymore, remove it from the MANIFEST

perf tests: Add LLVM test for eBPF on-the-fly compiling

2015-08-07T13:57:24+00:00

Previous patches introduce llvm__compile_bpf() to compile source file to
eBPF object. This patch adds testcase to test it. It also tests libbpf
by opening generated object after applying next patch which introduces
HAVE_LIBBPF_SUPPORT option.

Since llvm__compile_bpf() prints long messages which users who don't
explicitly test llvm doesn't care, this patch set verbose to -1 to
suppress all debug, warning and error message, and hint user use 'perf
test -v' to see the full output.

For the same reason, if clang is not found in PATH and there's no [llvm]
section in .perfconfig, skip this test.
