perf tools: Have the page size value available for all tools

2012-10-06T19:33:14+00:00

Its such a common need that we might as well have a global with that
value.

perf tools: Convert to BACKTRACE_SUPPORT

2012-10-02T21:36:45+00:00

For building perf without stack backtrace debug, we can set
NO_BACKTRACE=1 as a argument of make.  It then defines NO_BACKTRACE
macro for C code to do the proper handling.  However it usually used in
a negative semantics - e.g. #ifndef - so we saw double negations which
can be misleading.  Convert it to a positive form to make it more
readable and add _SUPPORT suffix for consistency.

perf tools: add NO_BACKTRACE for application self-debugging

2012-09-08T01:12:30+00:00

perf has support for self-debugging by defining dump_stack function.
This function uses backtrace and backtrace_symbols functions defined as
GNU extensions.

In Android, bionic does not offer support for these functions and
compilation will fail with the following error:

target  C: libperf <= tools/perf/util/util.c
tools/perf/util/util.c:4:22: fatal error: execinfo.h: No such file or directory
compilation terminated.

Add a compile-time option (NO_BACKTRACE) to enable or disable
self-debugging functionality in perf. This can also help in debugging
since it offers the possibility to turn on/off printing the backtrace.

perf tools: Add dump_stack function

2012-08-08T02:32:05+00:00

To help in debugging the tools, provides functionality roughly similar
to the function with the same name in the kernel.

Copied from glibc backtrace function man page.

perf tools: cleanup initialization of attr->size

2012-02-14T01:35:04+00:00

The perf_event_attr size needs to be initialized in all cases because it
captures the ABI version.

This patch moves the initialization of the field from the
perf_event_open() syscall stub to its proper location in the
event_attr_init().

perf tools: Change perf_guest default back to false

2012-02-14T01:14:44+00:00

Setting perf_guest to true by default makes no sense because the perf
subcommands can not setup guest symbol information and thus not process
and guest samples. The only exception is perf-kvm which changes the
perf_guest value on its own.  So change the default for perf_guest back
to false.

perf util: Move do_read from session to util

2011-01-03T18:50:55+00:00

Not really something to be exported from session.c. Rename it to
'readn' as others did in the past.
