2009-11-05sh: oprofile: Fix up count size mismatch for common impl.Paul Mundt1-1/+1
This reduces the 'count' size in the common support structure to 32-bits so that it matches up with what oprofile is expecting. The SH7750 code was using a nasty oprofilefs hack to expose the 48-bit counter, although no other implementations were. Now that the offending driver has been killed off, it's possible to restore some semblance of sanity. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-11-05sh: oprofile: Kill off bitrotted SH7750 driver.Paul Mundt3-289/+8
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.

2009-08-14sh: oprofile: Kill off dead valid_kernel_stack().Paul Mundt1-27/+0
This is no longer used, kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-08-13sh: Use the new stack unwinder APIMatt Fleming1-2/+3
Instead of implementing our own stack unwinder via dump_trace() we should use the new stack unwinder API because it is more modular. This change allows us to decouple the interface for generating stacktraces from the implementation of a stack unwinder.

2009-08-13sh: Use the generalized stacktrace opsMatt Fleming1-20/+36
Copy the stacktrace ops code from x86 and provide a central function for use by functions that need to dump a callstack. Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-04-16sh: Add support for SH7724 (SH-Mobile R2R) CPU subtype.Kuninori Morimoto1-0/+1
This implements initial support for the SH-Mobile R2R CPU. Based on Rev 0.11 of the initial SH7724 hardware manual. Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-03-03sh: Add support for SH7786 CPU subtype.Kuninori Morimoto1-0/+1
This adds preliminary support for the SH7786 CPU subtype. While this is a dual-core CPU, only UP is supported for now. L2 cache support is likewise not yet implemented. More information on this particular CPU subtype is available at: http://www.renesas.com/fmwk.jsp?cnt=sh7786_root.jsp&fp=/products/mpumcu/superh_family/sh7780_series/sh7786_group/ Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-12-22sh: oprofile: Backtrace support.Dave Peverley2-0/+127
This patch improves the oprofile support on sh and adds backtrace support. Signed-off-by: Dave Peverley <dpeverley@mpc-data.co.uk> Signed-off-by: Chris Smith <chris.smith@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: oprofile: Refactor common setup code for multiple driver support.Paul Mundt4-30/+178
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 Mundt1-2/+0
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>
2008-10-27sh: oprofile: Fix up the SH7750 performance counter name.Paul Mundt1-4/+2
Rather than varying this on a subtype level, we use the counter type as a generic identifier. This simplifies logic in the userspace tools where no fundamental difference exists across the various subtypes. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-11-07sh: Add -Werror for clean directories.Paul Mundt1-0/+1
Follow the MIPS and sparc64 changes for -Werror instrumentation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-30sh: Make SH7750 oprofile compile again.Paul Mundt1-15/+7
Converts from the profile notifier to the timer hook. Follows the generic timer interrupt-based change. This really wants to be converted to perfmon.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-10-19Combine instrumentation menus in kernel/Kconfig.instrumentationMathieu Desnoyers1-23/+0
Quoting Randy: "It seems sad that this patch sources Kconfig.marker, a 7-line file, 20-something times. Yes, you (we) don't want to put those 7 lines into 20-something different files, so sourcing is the right thing. However, what you did for avr32 seems more on the right track to me: make _one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES, and MARKERS and then use (source) that in all of the arches."

2007-02-13sh: Fixup cpu_data references for the non-boot CPUs.Paul Mundt1-1/+1
There are a lot of bogus cpu_data-> references that only end up working for the boot CPU, convert these to current_cpu_data to fixup SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-12[PATCH] mark struct file_operations const 2Arjan van de Ven1-1/+1
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2006-06-26[PATCH] oprofile: Fix unnecessary clevernessMarkus Armbruster1-1/+1
nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on model->num_counters (number of performance counters) being less than 10. While this is currently the case, it's too clever by half. Other archs aren't quite as clever: they assume 100. I suggest to normalize them all to 1000.

2005-04-16Linux-2.6.12-rc2Linus Torvalds4-0/+340
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!
