perf tools: Use just forward declarations for struct thread where possible

2017-04-24T16:43:35+00:00

Removing various instances of unnecessary includes, reducing the maze of
header dependencies.

perf tools: Remove string.h, unistd.h and sys/stat.h from util.h

2017-04-24T16:43:33+00:00

Not needed in this header, added to the places that need FILE,
putchar(), access() and a few other prototypes.

perf tools: Replace STR() calls with __stringify()

2017-04-19T16:01:47+00:00

Both do the same thing, the later is the one we get from
linux/stringify.h, i.e. we now use the same function name/practice as
the kernel sources.

perf annotate: Improve support for ARM

2016-11-25T13:38:56+00:00

By using arch->init() to set up some regular expressions to associate
ins_ops to ARM instructions, ditching that old table that has
instructions not present on ARM.

Take advantage of having an arch->init() to hide more arm specific stuff
from the common code, like the objdump details.

The regular expressions comes from a patch written by Kim Phillips.

perf annotate: Add per arch instructions annotate handlers

2016-11-17T20:31:59+00:00

Another step in supporting cross annotation.

The arch specific tables are put in:

   tools/perf/arch/$ARCH/annotation/instructions.c

which, so far, just plug instructions to a bunch of parsers/formatters,
but may have more as the need arises.

This is an alternative implementation to a previous attempt made by Ravi
Bangoria.

perf coresight: Removing miscellaneous debug output

2016-10-24T14:07:47+00:00

Printing the full path of the selected link is obviously not needed,
hence removing.

perf tools: Add coresight etm PMU record capabilities

2016-09-22T15:19:40+00:00

Coresight ETMs are IP blocks used to perform HW assisted tracing on a
CPU core.  This patch introduce the required auxiliary API functions
allowing the perf core to interact with a tracer.

perf probe: Support probing on offline cross-arch binary

2016-09-01T15:41:09+00:00

Support probing on offline cross-architecture binary by adding getting
the target machine arch from ELF and choose correct register string for
the machine.

Here is an example:
  -----
  $ perf probe --vmlinux=./vmlinux-arm --definition 'do_sys_open $params'
  p:probe/do_sys_open do_sys_open+0 dfd=%r5:s32 filename=%r1:u32 flags=%r6:s32 mode=%r3:u16
  -----

Here, we can get probe/do_sys_open from above and append it to to the target
machine's tracing/kprobe_events file in the tracefs mountput, usually
/sys/kernel/debug/tracing/kprobe_events (or /sys/kernel/tracing/kprobe_events).
