2012-11-05perf report: Postpone objdump check until annotation requestedNamhyung Kim
David reported that current perf report refused to run on a data file captured from a different machine because of objdump.

2012-11-05perf tools: Introduce struct hist_browser_timerNamhyung Kim
Currently various hist browser functions receive 3 arguments for refreshing histogram but only used from a few places. Also it's only for perf top command so that it can be NULL for other (and probably most) cases. Pack them into a struct in order to reduce number of those unused arguments. This is a mechanical change and does not intend a functional change.

2012-11-05perf tools: Use normalized arch name for searching objdump pathNamhyung Kim
David reported that perf report for i686 target data on x86_64 host failed to work because it tried to find out cross-compiled objdump. However objdump for x86_64 is compatible to i686 so that it doesn't need to do it at all. To prevent similar artifacts, normalize arch name when comparing host and file architectures.

2012-10-31perf tools: Further speed up the perf buildIngo Molnar
There's another source of overhead in the perf version string generator: git update-index -q --refresh ... which will iterate the whole checked out tree. This can be pretty slow on NFS volumes, but takes some time even with local SSD disks and a fully cached kernel tree: $ perf stat --null --repeat 3 --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN PERF_VERSION = 3.7.rc3.g5399b3b.dirty PERF_VERSION = 3.7.rc3.g5399b3b.dirty PERF_VERSION = 3.7.rc3.g5399b3b.dirty Performance counter stats for 'util/PERF-VERSION-GEN' (3 runs): 0.306999221 seconds time elapsed ( +- 0.56% ) So remove the .dirty differentiator as well - it adds little information because locally patched git trees are common, but seldom are the perf tools modified. So a lot of version strings are reported as 'dirty' while in fact they are pristine perf builds. For example 99% of my perf builds are not patched but the kernel tree is slightly patched, which adds the .dirty tag. Eliminating that tag speeds up version generation by another order of magnitude: $ perf stat --null --repeat 3 --sync --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN PERF_VERSION = 3.7.rc3.g4b0bd3 PERF_VERSION = 3.7.rc3.g4b0bd3 PERF_VERSION = 3.7.rc3.g4b0bd3 Performance counter stats for 'util/PERF-VERSION-GEN' (3 runs): 0.021270923 seconds time elapsed ( +- 1.94% ) (Also clean up some of the comments around this code.)

2012-10-31perf tools: Speed up the perf build time by simplifying the perf --version ↵Ingo Molnar
string generation Building perf is pretty slow on trees that have a lot of commits relative to the nearest Git tag. This slowness manifests itself during version string generation: $ perf stat --null --repeat 3 --sync --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN PERF_VERSION = 3.7.rc3.1458.g5399b3b PERF_VERSION = 3.7.rc3.1458.g5399b3b PERF_VERSION = 3.7.rc3.1458.g5399b3b Performance counter stats for 'util/PERF-VERSION-GEN' (3 runs): 2.857503976 seconds time elapsed ( +- 0.22% ) The build can be even slower than that, when one over NFS volumes. The reason for the slowness is that util/PERF-VERSION-GEN uses "git describe" to generate the string, which has to count the "number of commits distance" from the nearest tag - the ".1458." count in the output above. For that Git had to extract and decompress 1458 Git objects, which takes time and bandwidth. But this "number of commits" value is mostly irrelevant in practice. We either want to know an approximate tag name, or we want to know the precise sha1. So this patch simplifies the version string to: PERF_VERSION = 3.7.rc3.g5399b3b.dirty which speeds up the version string generation script by an order of magnitude: $ perf stat --null --repeat 3 --sync --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN PERF_VERSION = 3.7.rc3.g5399b3b.dirty PERF_VERSION = 3.7.rc3.g5399b3b.dirty PERF_VERSION = 3.7.rc3.g5399b3b.dirty Performance counter stats for 'util/PERF-VERSION-GEN' (3 runs): 0.307633559 seconds time elapsed ( +- 0.84% ) Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Andrew Vagin <avagin@openvz.org> Cc: Borislav Petkov <bp@amd64.org> Cc: David Howells <dhowells@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/20121030084600.GB8245@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
