linux.git/arch/mips/include/asm/Kbuild, branch v3.11 Linux kernel source tree 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.

UAPI: Place comments in empty arch Kbuilds to make them non-empty 2012-10-17T11:31:16+00:00 David Howells dhowells@redhat.com 2012-10-17T11:31:16+00:00 4c7b279c1a03392184c75fa5f38b58e2b9c882cf Place comments in: arch/mips/include/asm/Kbuild arch/tile/include/arch/Kbuild to make them non-empty so that the patch program doesn't remove them when it reduces them to nothing. Possibly they should be just deleted, but it's possible that they'll acquire generic-y or genhdr-y lines in future, so I'm keeping them around for the moment. Note that MIPS will compile happily if the file is deleted instead. I haven't tested TILE, but I suspect it will be the same there.
