tracing: Fix ftrace stack trace entries

2012-04-13T15:33:47+00:00

commit 01de982abf8c9e10fc3089e10585cd2cc914bdab upstream.

8 hex characters tell only half the tale for 64 bit CPUs,
so use the appropriate length.

tracing: Have dynamic size event stack traces

2011-07-14T20:36:53+00:00

Currently the stack trace per event in ftace is only 8 frames.
This can be quite limiting and sometimes useless. Especially when
the "ignore frames" is wrong and we also use up stack frames for
the event processing itself.

Change this to be dynamic by adding a percpu buffer that we can
write a large stack frame into and then copy into the ring buffer.

For interrupts and NMIs that come in while another event is being
process, will only get to use the 8 frame stack. That should be enough
as the task that it interrupted will have the full stack frame anyway.

tracing: Remove special traces

2010-07-20T12:31:07+00:00

Special traces type was only used by sysprof. Lets remove it now
that sysprof ftrace plugin has been dropped.

tracing: Remove ksym tracer

2010-07-15T21:59:33+00:00

The ksym (breakpoint) ftrace plugin has been superseded by perf
tools that are much more poweful to use the cpu breakpoints.
This tracer doesn't bring more feature. It has been deprecated
for a while now, lets remove it.

tracing: Remove kmemtrace ftrace plugin

2010-06-09T15:31:22+00:00

We have been resisting new ftrace plugins and removing existing
ones, and kmemtrace has been superseded by kmem trace events
and perf-kmem, so we remove it.

tracing: Remove boot tracer

2010-06-08T21:31:28+00:00

The boot tracer is useless. It simply logs the initcalls
but in fact these initcalls are also logged through printk
while using the initcall_debug kernel parameter.

Nobody seem to be using it so far. Then just remove it.

x86, perf, bts, mm: Delete the never used BTS-ptrace code

2010-03-26T10:33:55+00:00

Support for the PMU's BTS features has been upstreamed in
v2.6.32, but we still have the old and disabled ptrace-BTS,
as Linus noticed it not so long ago.

It's buggy: TIF_DEBUGCTLMSR is trampling all over that MSR without
regard for other uses (perf) and doesn't provide the flexibility
needed for perf either.

Its users are ptrace-block-step and ptrace-bts, since ptrace-bts
was never used and ptrace-block-step can be implemented using a
much simpler approach.

So axe all 3000 lines of it. That includes the *locked_memory*()
APIs in mm/mlock.c as well.
