perf tools: Create config.detected into OUTPUT directory

2015-07-01T20:53:49+00:00

Create config.detected into OUTPUT directory instead of source
directory.

This fixes parallel builds that share the same source directory.

Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2015-06-22T22:45:41+00:00

Pull perf fixes from Ingo Molnar:
 "These are the left over fixes from the v4.1 cycle"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf tools: Fix build breakage if prefix= is specified
  perf/x86: Honor the architectural performance monitoring version
  perf/x86/intel: Fix PMI handling for Intel PT
  perf/x86/intel/bts: Fix DS area sharing with x86_pmu events
  perf/x86: Add more Broadwell model numbers
  perf: Fix ring_buffer_attach() RCU sync, again

perf tools: Fix build breakage if prefix= is specified

2015-06-19T19:39:42+00:00

Invoking Makefile.perf with prefix= breaks the build since Makefile.perf
hands that variable down to Makefile.build where it overrides

    prefix       := $(subst ./,,$(OUTPUT)$(dir)/)

leading to errors like this:

    No rule to make target '/usrabspath.o', needed by '/usrlibperf-in.o'

perf build: Do not fail on missing Build file

2015-05-29T15:44:25+00:00

Allow nesting into directories without Build file. Currently we force
include of the Build file, which fails the build when the Build file is
missing.

We already support empty *-in.o' objects if there's nothing in the
directory to be compiled, so we can just use it for missing Build file
cases.

Also adding this case under tests.

tools build: Change FEATURE_TESTS and FEATURE_DISPLAY to weak binding

2015-05-18T15:36:46+00:00

Replace strong binding of FEATURE_TESTS and FEATURE_DISPLAY by weak
binding. This patch enables other makefiles which include
tools/build/Makefile.feature enable only limited feathres to check.

Add the new libperf build object so it's separated from the rest of the
perf code and could be librarized.
