ftrace: Build without frame pointers on Microblaze

Microblaze doesn't need/support FRAME_POINTERS in order to have a working function tracer. The patch remove Kconfig warning.

trace, documentation: Fix branch profiling location in debugfs

2011-03-17T08:10:45Z

The debugfs interface for branch profiling is through /sys/kernel/debug/tracing/trace_stat/branch_annotated /sys/kernel/debug/tracing/trace_stat/branch_all so update the Kconfig accordingly. Signed-off-by: David Rientjes Cc: Steven Rostedt LKML-Reference: Signed-off-by: Ingo Molnar

perf: Clean up power events by introducing new, more generic ones

2011-01-04T07:16:54Z

Add these new power trace events: power:cpu_idle power:cpu_frequency power:machine_suspend The old C-state/idle accounting events: power:power_start power:power_end Have now a replacement (but we are still keeping the old tracepoints for compatibility): power:cpu_idle and power:power_frequency is replaced with: power:cpu_frequency power:machine_suspend is newly introduced. Jean Pihet has a patch integrated into the generic layer (kernel/power/suspend.c) which will make use of it. the type= field got removed from both, it was never used and the type is differed by the event type itself. perf timechart userspace tool gets adjusted in a separate patch.

[S390] ftrace: build without frame pointers on s390

2010-11-10T09:05:54Z

s390 doesn't need FRAME_POINTERS in order to have a working function tracer. We don't need frame pointers in order to get strack traces since we always have valid backchains by using the -mkernel-backchain gcc option. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

ftrace: Rename config option HAVE_C_MCOUNT_RECORD to HAVE_C_RECORDMCOUNT

2010-10-15T03:32:44Z

The config option used by archs to let the build system know that the C version of the recordmcount works for said arch is currently called HAVE_C_MCOUNT_RECORD which enables BUILD_C_RECORDMCOUNT. To be more consistent with the name that all archs may use, it has been renamed to HAVE_C_RECORDMCOUNT. This will be less confusing since we are building a C recordmcount and not a mcount_record.

ftrace/x86: Add support for C version of recordmcount

2010-10-14T20:52:41Z

This patch adds the support for the C version of recordmcount and compile times show ~ 12% improvement. After verifying this works, other archs can add: HAVE_C_MCOUNT_RECORD in its Kconfig and it will use the C version of recordmcount instead of the perl version.

ARM: 6314/1: ftrace: allow build without frame pointers on ARM

2010-09-02T14:24:53Z

With a new enough GCC, ARM function tracing can be supported without the need for frame pointers. This is essential for Thumb-2 support, since frame pointers aren't available then. Acked-by: Catalin Marinas Acked-by: Steven Rostedt Signed-off-by: Rabin Vincent Signed-off-by: Russell King
