perf fs: Rename NAME_find_mountpoint() to NAME__mountpoint()

2013-11-05T18:15:00Z

Shorten it, "finding" it is an implementation detail, what callers want is the pathname, not to ask for it to _always_ do the lookup. And the existing implementation already caches it, i.e. it doesn't "finds" it on every call.

perf tools: Factor sysfs code into generic fs object

2013-11-05T17:44:26Z

Moving sysfs code into generic fs object and preparing it to carry procfs support. This should be merged with tools/lib/lk/debugfs.c at some point in the future.

tools/perf/stat: Add perf stat --transaction

2013-10-04T08:06:07Z

Add support to perf stat to print the basic transactional execution statistics: Total cycles, Cycles in Transaction, Cycles in aborted transsactions using the in_tx and in_tx_checkpoint qualifiers. Transaction Starts and Elision Starts, to compute the average transaction length. This is a reasonable overview over the success of the transactions. Also support architectures that have a transaction aborted cycles counter like POWER8. Since that is awkward to handle in the kernel abstract handle both cases here. Enable with a new --transaction / -T option. This requires measuring these events in a group, since they depend on each other. This is implemented by using TM sysfs events exported by the kernel Signed-off-by: Andi Kleen Acked-by: Arnaldo Carvalho de Melo Signed-off-by: Peter Zijlstra Link: http://lkml.kernel.org/r/1377128846-977-5-git-send-email-andi@firstfloor.org Signed-off-by: Ingo Molnar

perf pmu: Privatize perf_pmu_{format,alias} structs

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.
