linux-toradex.git/arch/um/include/asm/Kbuild, branch v3.10.76 Linux kernel for Apalis and Colibri modules tracing,x86: Add a TSC trace_clock 2012-11-13T20:48:27+00:00 David Sharp dhsharp@google.com 2012-11-13T20:18:21+00:00 8cbd9cc6254065c97c4bac42daa55ba1abe73a8e In order to promote interoperability between userspace tracers and ftrace, add a trace_clock that reports raw TSC values which will then be recorded in the ring buffer. Userspace tracers that also record TSCs are then on exactly the same time base as the kernel and events can be unambiguously interlaced. Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large timestamp values. v2: Move arch-specific bits out of generic code. v3: Rename "x86-tsc", cleanups v7: Generic arch bits in Kbuild.

In order to promote interoperability between userspace tracers and ftrace,
add a trace_clock that reports raw TSC values which will then be recorded
in the ring buffer. Userspace tracers that also record TSCs are then on
exactly the same time base as the kernel and events can be unambiguously
interlaced.

Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large
timestamp values.

v2:
Move arch-specific bits out of generic code.
v3:
Rename "x86-tsc", cleanups
v7:
Generic arch bits in Kbuild.

asm-generic: Add default clkdev.h 2012-10-03T19:33:53+00:00 Mark Brown broonie@opensource.wolfsonmicro.com 2012-09-05T04:04:14+00:00 e7a570ff7dff9af6e54ff5e580a61ec7652137a0 Ease the deployment of clkdev by providing a default asm/clkdev.h for use if the arch does not have an include/asm/clkdev.h. Due to limitations in Kbuild we manually add clkdev.h to all architectures that don't have one rather than having the header appear by default.
