2010-10-27sh: oprofile: Fix up and extend op_name_from_perf_id().Paul Mundt
op_name_from_perf_id() currently returns a local variable, which isn't terribly productive. As we only handle a single PMU case for now, simply allocate and free the string from the arch init/exit context and have op_name_from_perf_id() hand back the cached string. This also takes UTS_MACHINE in to account, given that we build for multiple architectures. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-11sh: oprofile: Use perf-events oprofile backendMatt Fleming
Now that we've got a generic perf-events based oprofile backend we might as well make use of it seeing as SH doesn't do anything special with its oprofile backend. Also introduce a new CONFIG_HW_PERF_EVENTS symbol so that we can fallback to using the timer interrupt for oprofile if the CPU doesn't support perf events. Also, to avoid a section mismatch warning we need to annotate oprofile_arch_exit() with an __exit marker.

2009-11-05sh: oprofile: Kill off bitrotted SH7750 driver.Paul Mundt
This kills off the old SH7750 oprofile driver, preferring perf instead. As this driver has a number of bugs that no one seems to have noticed, it's safe to kill this off now rather than providing an extended transition period. The old oprofile framework is still kept in place for now, primarily to give out-of-tree drivers a chance to transition off. But this too will be killed off in short order.

2008-12-22sh: oprofile: Refactor common setup code for multiple driver support.Paul Mundt
This re-implements the old op_model_null code in to something more generic, where multiple drivers, backtrace, etc. can all be interfaced. Based largely on arch/mips/oprofile/common.c. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Disable -Werror for arch/sh/oprofile/.Paul Mundt
drivers/oprofile/ objects have proven to be problematic in this regard, so simply disable -Werror for now. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Add -Werror for clean directories.Paul Mundt
Follow the MIPS and sparc64 changes for -Werror instrumentation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Add SH7750S/SH7091 rules for SH7750 oprofile driver.Paul Mundt
Update oprofile build rules for additional subtypes, particularly SH7750S/SH7091. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
