2013-06-13turbostat: Increase output buffer size to accommodate C8-C10Josh Triplett1-1/+1
On platforms with C8-C10 support, the additional C-states cause turbostat to overrun its output buffer of 128 bytes per CPU. Increase this to 256 bytes per CPU. [ As a bugfix, this should go into 3.10; however, since the C8-C10 support didn't go in until after 3.9, this need not go into any stable kernel. ] Signed-off-by: Josh Triplett <[email protected]> Cc: Len Brown <[email protected]> Cc: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2013-05-29perf tests: Fix exclude_guest|exclude_host checking for attr testsJiri Olsa2-4/+4
We have a one of the event open fallback case in __perf_evsel__open where we zero exclude_guest|exclude_host fields. This means there's no way for attr tests to find out what's the right value for those fields, so we need to check for both 0 and 1. Luckily we still have other event parsing tests for those fields.

2013-05-28perf tools: Add automated make test suiteJiri Olsa1-0/+138
Adding automated test for testing the build process. To run it you need to be in perf directory or specify one with PERF variable. It's also possible to specify optional Makefile to test via MK variable. Whole suite is executed twice, the second time with O=/tmp/xxx option added. To run the whole suite: $ make -f tests/make - make_pure: cd . && make -f Makefile test: test -x ./perf - make_clean_all: cd . && make -f Makefile clean all test: test -x ./perf - make_python_perf_so: cd . && make -f Makefile python/perf.so test: test -f ./python/perf.so - make_debug: cd . && make -f Makefile DEBUG=1 test: test -x ./perf - make_no_libperl: cd . && make -f Makefile NO_LIBPERL=1 test: test -x ./perf You see command line for 'make_pure' test right away, and the output is stored into 'make_pure' file. To run simple test: $ make -f tests/make make_debug - make_debug: cd . && make -f Makefile DEBUG=1 test: test -x ./perf At this moment tests checks for successfull build and for existence of several built files. Additional after-build checks could be added.

2013-05-28perf hists: Rename hist_entry__add_pair argumentsJiri Olsa1-3/+3
The current logic is to attach pair to the leader hist_entry. Arguments of hist_entry__add_pair function were placed the other way round.. driving me crazy. I.e. list_add_tail expects (new_node, head).

2013-05-28perf diff: Use internal rb tree for hists__precomputeJiri Olsa1-3/+10
There's missing change for hists__precompute to iterate either entries_collapsed or entries_in tree. The change was initiated for hists_compute_resort function in commit: 66f97ed perf diff: Use internal rb tree for compute resort but was missing for hists__precompute function changes.

2013-05-28perf report: Don't bother locking when adding hist entriesNamhyung Kim1-4/+0
The 'perf report'command is single-threaded, so no need to grab a lock. Although the fast path of pthread_mutex_[un]lock() is very fast, there's a ~3% gain by eliminating it when we have huge sample data. $ perf record -a -F 100000 -o perf.data.bench -- perf bench sched all $ perf record -e cycles:upp -o perf.data.before -- \ > perf report -i perf.data.bench --stdio > /dev/null ... apply this patch ... $ perf record -e cycles:upp -o perf.data.after -- \ > perf report -i perf.data.bench --stdio > /dev/null $ perf diff perf.data.{before,after} | grep pthread +0.02% libpthread-2.15.so [.] _pthread_cleanup_push_defer +0.02% libpthread-2.15.so [.] _pthread_cleanup_pop_restore 0.05% -0.05% perf [.] pthread_mutex_unlock@plt 0.05% -0.05% perf [.] pthread_mutex_lock@plt 1.01% -1.01% libpthread-2.15.so [.] pthread_mutex_lock 1.68% -1.68% libpthread-2.15.so [.] __pthread_mutex_unlock_usercnt 0.05% -0.05% libpthread-2.15.so [.] pthread_mutex_unlock Signed-off-by: Namhyung Kim <[email protected]> Acked-by: Jiri Olsa <[email protected]> Cc: David Ahern <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Stephane Eranian <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
