perf list: List kernel supplied event aliases

2013-07-12T16:53:53Z

List the kernel supplied pmu event aliases in perf list It's better when the users can actually see them. Signed-off-by: Andi Kleen Link: http://lkml.kernel.org/r/1366480949-32292-2-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo

perf pmu: Privatize perf_pmu_{format,alias} structs

2013-01-24T19:40:51Z

They are only used in pmu.c, so no need to make them public in pmu.h.

perf pmu: Fix usage of __ in struct names

2013-01-24T19:40:50Z

In tools/perf we use a convention where __ separates the struct name from the function name for functions that operate on a struct instance. Fix this usage by removing it from the struct names and fix also the associated functions.

perf tools: Fix PMU format parsing test failure

2013-01-24T19:40:47Z

On POWER, the 'perf format parsing' test always fails. Looks like it is because memset() is being passed number of longs rather than number of bytes. It is interesting that the test always passes on my x86 box. With this patch, the test passes on POWER and continues to pass on x86.

perf tools: Fix PMU object alias initialization

2012-10-24T08:41:26Z

The pmu_lookup should return pmus that do not expose the 'events' group attribute in sysfs. Also it should fail when any other error during 'events' lookup is hit (pmu_aliases fails).

perf tools: Add pmu mappings to header information

2012-08-22T18:22:55Z

With dynamic pmu allocation there are also dynamically assigned pmu ids. These ids are used in event->attr.type to describe the pmu to be used for that event. The information is available in sysfs, e.g: /sys/bus/event_source/devices/breakpoint/type: 5 /sys/bus/event_source/devices/cpu/type: 4 /sys/bus/event_source/devices/ibs_fetch/type: 6 /sys/bus/event_source/devices/ibs_op/type: 7 /sys/bus/event_source/devices/software/type: 1 /sys/bus/event_source/devices/tracepoint/type: 2 These mappings are needed to know which samples belong to which pmu. If a pmu is added dynamically like for ibs_fetch or ibs_op the type value may vary. Now, when decoding samples from perf.data this information in sysfs might be no longer available or may have changed. We need to store it in perf.data. Using the header for this. Now the header information created with perf report contains an additional section looking like this: # pmu mappings: ibs_op = 7, ibs_fetch = 6, cpu = 4, breakpoint = 5, tracepoint = 2, software = 1 Signed-off-by: Robert Richter Acked-by: Peter Zijlstra Cc: Ingo Molnar Cc: Jiri Olsa Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1345144224-27280-9-git-send-email-robert.richter@amd.com Signed-off-by: Arnaldo Carvalho de Melo
