perf fs: Add procfs support

2013-11-05T18:15:07+00:00

Adding procfs support into fs class. The interface function: const char *procfs__mountpoint(void); provides existing mountpoint path for procfs.

tools/perf: Turn strlcpy() into a __weak function

2013-10-09T06:48:49+00:00

The strlcpy() feature check slows every build unnecessarily - so make it a __weak function so it does not have to be auto-detected. If the libc (or any other library) has an strlcpy() implementation it will be used - otherwise our fallback is active.

perf tools: Default to cpu// for events v5

2013-07-12T16:53:52+00:00

When an event fails to parse and it's not in a new style format, try to parse it again as a cpu event. This allows to use sysfs exported events directly without //, so you can use perf record -e mem-loads ... instead of perf record -e cpu/mem-loads/ Signed-off-by: Andi Kleen Link: http://lkml.kernel.org/r/1366480949-32292-1-git-send-email-andi@firstfloor.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Fix PMU format parsing test failure

2013-01-24T19:40:47+00:00

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: Fix UAPI fallout

The UAPI commits forgot to test tooling builds such as tools/perf/, and this fixes the fallout. Manual conversion. Signed-off-by: Ingo Molnar Signed-off-by: Linus Torvalds

perf: Handle new rbtree implementation

2012-10-13T01:12:09+00:00

Perf build fails with the new rbtree implementation: ../../lib/rbtree.c:24:36: fatal error: linux/rbtree_augmented.h: No such file or directory compilation terminated. Fix by updating the Makefile and adding a btree_augmented.h wrapper.

perf: fix duplicate header inclusion

#include somehow got duplicated on its way to linus's tree (probably as a conflict resolution as things got sent through multiple trees) Signed-off-by: Michel Lespinasse Cc: Adrian Hunter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

rbtree: adjust node color in __rb_erase_color() only when necessary

2012-10-09T07:22:34+00:00

In __rb_erase_color(), we were always setting a node to black after exiting the main loop. And in one case, after fixing up the tree to satisfy all rbtree invariants, we were setting the current node to root just to guarantee a loop exit, at which point the root would be set to black. However this is not necessary, as the root of an rbtree is already known to be black. The only case where the color flip is required is when we exit the loop due to the current node being red, and it's easiest to just do the flip at that point instead of doing it after the loop.
