perf tools: Include tools/lib/api/ in MANIFEST

2014-01-13T13:06:26Z

When 553873e1df63 renamed tools/lib/lk to tools/lib/api we forgot to do the switch in tools/perf/MANIFEST, breaking tarball building: [acme@ssdandy linux]$ make perf-targz-src-pkg TAR [acme@ssdandy linux]$ tar xf perf-3.13.0-rc4.tar.gz -C /tmp/tmp.OgdYyvp77p/ [acme@ssdandy linux]$ make -C /tmp/tmp.OgdYyvp77p/perf-3.13.0-rc4/tools/perf make: Entering directory `/tmp/tmp.OgdYyvp77p/perf-3.13.0-rc4/tools/perf' BUILD: Doing 'make -j8' parallel build FLEX util/pmu-flex.c CC util/evlist.o CC util/evsel.o util/evsel.c:12:28: fatal error: api/fs/debugfs.h: No such file or directory compilation terminated.

So that it can be shared with others like libtraceevent.

tools lib symbol: Start carving out symbol parsing routines from perf

2013-12-13T13:30:20Z

Eventually this should be useful to other tools/ living utilities. For now don't try to build any .a, just trying the minimal approach of separating existing code into multiple .c files that can then be included wherever they are needed, using whatever build machinery already in place.

perf tools: Introduce tools/lib/lk library

2013-03-15T16:06:00Z

This introduces the tools/lib/lk library, that will gradually have the routines that now are used in tools/perf/ and other tools and that can be shared. Start by carving out debugfs routines for general use.

perf kvm: Events analysis tool

2012-09-21T15:51:22Z

Add 'perf kvm stat' support to analyze kvm vmexit/mmio/ioport smartly Usage: - kvm stat run a command and gather performance counter statistics, it is the alias of perf stat - trace kvm events: perf kvm stat record, or, if other tracepoints are interesting as well, we can append the events like this: perf kvm stat record -e timer:* -a If many guests are running, we can track the specified guest by using -p or --pid, -a is used to track events generated by all guests. - show the result: perf kvm stat report The output example is following: 13005 13059 total 2 guests are running on the host Then, track the guest whose pid is 13059: ^C[ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.253 MB perf.data.guest (~11065 samples) ] See the vmexit events: Analyze events for all VCPUs: VM-EXIT Samples Samples% Time% Avg time APIC_ACCESS 460 70.55% 0.01% 22.44us ( +- 1.75% ) HLT 93 14.26% 99.98% 832077.26us ( +- 10.42% ) EXTERNAL_INTERRUPT 64 9.82% 0.00% 35.35us ( +- 14.21% ) PENDING_INTERRUPT 24 3.68% 0.00% 9.29us ( +- 31.39% ) CR_ACCESS 7 1.07% 0.00% 8.12us ( +- 5.76% ) IO_INSTRUCTION 3 0.46% 0.00% 18.00us ( +- 11.79% ) EXCEPTION_NMI 1 0.15% 0.00% 5.83us ( +- -nan% ) Total Samples:652, Total events handled time:77396109.80us.

perf tools: Fix make tarballs

2012-05-30T18:05:59Z

The patch series that introduced the top level tools/ makefile and the libtraceevent broke this feature where files needed to build in a detached tarball were not included in the MANIFEST file and thus not included in the tarball. Fix it by adding the relevant files to the MANIFEST.
