2013-11-14tools/perf/build: Fix feature-libunwind-debug-frame handlingIngo Molnar
Set feature-libunwind-debug-frame. We don't want it in CORE_FEATURE_TESTS because it's not the generic case, but we need to set it in the !feature-libunwind case. Also, because x86 distributions typically don't have dwarf_find_debug_frame() unwinding method: test-libunwind-debug-frame.c:(.text+0x31): undefined reference to `_Ux86_64_dwarf_find_debug_frame' Restrict this new API to ARM for the time being. With this patch test-all.c works again, so repeat perf builds are fast again: comet:~/tip> perf stat --null --repeat 5 make -C tools/perf/ [...] 0,452899660 seconds time elapsed ( +- 0,11% ) While with before it was: comet:~/tip> perf stat --null --repeat 5 make -C tools/perf/ [...] 1,674001829 seconds time elapsed ( +- 0,16% ) [ Includes fix to config/feature-checks/Makefile from Will Deacon. ] Tested-by: Will Deacon <will.deacon@arm.com> Tested-by: Jean Pihet <jean.pihet@linaro.org> Cc: Russell King <rmk@arm.linux.org.uk> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Arnaldo Carvalho de Melo <acme@infradead.org> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/n/tip-scsoctqzmou3rpkixCHezy9e@git.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
2013-11-14Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull ARM updates from Russell King: "Included in this series are: 1. BE8 (modern big endian) changes for ARM from Ben Dooks 2. big.Little support from Nicolas Pitre and Dave Martin 3. support for LPAE systems with all system memory above 4GB 4. Perf updates from Will Deacon 5. Additional prefetching and other performance improvements from Will. 6. Neon-optimised AES implementation fro Ard. 7. A number of smaller fixes scattered around the place. There is a rather horrid merge conflict in tools/perf - I was never notified of the conflict because it originally occurred between Will's tree and other stuff. Consequently I have a resolution which Will forwarded me, which I'll forward on immediately after sending this mail. The other notable thing is I'm expecting some build breakage in the crypto stuff on ARM only with Ard's AES patches. These were merged into a stable git branch which others had already pulled, so there's little I can do about this. The problem is caused because these patches have a dependency on some code in the crypto git tree - I tried requesting a branch I can pull to resolve these, and all I got each time from the crypto people was "we'll revert our patches then" which would only make things worse since I still don't have the dependent patches. I've no idea what's going on there or how to resolve that, and since I can't split these patches from the rest of this pull request, I'm rather stuck with pushing this as-is or reverting Ard's patches. Since it should "come out in the wash" I've left them in - the only build problems they seem to cause at the moment are with randconfigs, and since it's a new feature anyway. However, if by -rc1 the dependencies aren't in, I think it'd be best to revert Ard's patches" I resolved the perf conflict roughly as per the patch sent by Russell, but there may be some differences. Any errors are likely mine.

2013-10-09tools/perf/build: Speed up auto-detectionIngo Molnar
The detection of certain rarely detected features can be delayed to when they are actually needed. So speed up the common case of auto-detection by pre-building only a core set of features and populating only their feature-flags. [ Features not listed in CORE_FEATURES need to built explicitly via the feature_check() function. ] (Also order the feature names alphabetically, while at it.)

2013-10-09tools/perf/build: Add 'autodep' functionality, generate feature test ↵Ingo Molnar
dependencies automatically Use GCC's -MD feature to generate a dependency file for each feature test .c file, and include that .d file in the config/feature-checks/Makefile. This allows us to do two things: - speed up feature tests - detect removal or changes in build dependencies - including system libraries/headers Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Namhyung Kim <namhyung@kernel.org> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/n/tip-Jfma8pmPnnqzpxjbs3hpgmsj@git.kernel.org Signed-off-by: Ingo Molnar <mingo@kernel.org>
2013-10-09tools/perf/build: Add feature check core codeIngo Molnar
Start the split-out of the feature check code by adding a list of features to be tested, and rules to process that list by building its matching feature-check file in config/feature-checks/test-<feature>.c. Add 'hello' as the initial feature. This structure will allow us to build split-out feature checks in parallel and thus speed up feature detection dramatically. No change in functionality: no feature check is used by the build rules yet.
