linux.git/arch/sh/include/asm/Kbuild, branch v3.12.65 Clone of https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git 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.

sh: hw-breakpoints: Add preliminary support for SH-4A UBC. 2009-12-08T06:02:27+00:00 Paul Mundt lethal@linux-sh.org 2009-11-09T07:27:40+00:00 09a072947791088b88ae15111cf68fc5aaaf758d This adds preliminary support for the SH-4A UBC to the hw-breakpoints API. Presently only a single channel is implemented, and the ptrace interface still needs to be converted. This is the first step to cleaning up the long-standing UBC mess, making the UBC more generally accessible, and finally making it SMP safe. An additional abstraction will be layered on top of this as with the perf events code to permit the various CPU families to wire up support for their own specific UBCs, as many variations exist.
