MIPS: oprofile: Add callgraph support

2011-06-15T12:35:34Z

Stack unwinding is done by code examination. For kernelspace, the already existing unwind function is utilized that uses kallsyms to quickly find the beginning of functions. For userspace a new function was added that examines code at and before the pc. Signed-off-by: Daniel Kalmar Signed-off-by: Gergely Kis Signed-off-by: Robert Richter

MIPS: Loongson: Add oprofile support

2009-09-17T18:07:47Z

This kernel support is needed by the user-space tool:oprofile to profile linux kernel or applications via loongson2 performance counters. you can enable this driver via CONFIG_OPROFILE = y or m. On Loongson2 there are two performance counters, each one can count 16 events respectively. when anyone of the performance counter overflows, an interrupt will be generated and is routed to the IRQ MIPS_CPU_IRQ_BASE + 6.

on_each_cpu(): kill unused 'retry' parameter

2008-06-26T09:24:38Z

It's not even passed on to smp_call_function() anymore, since that was removed. So kill it. Acked-by: Jeremy Fitzhardinge Reviewed-by: Paul E. McKenney Signed-off-by: Jens Axboe

[MIPS] Allow hardwiring of the CPU type to a single type for optimization.

2007-10-11T22:46:15Z

This saves a few k on systems which only ever ship with a single CPU type. Signed-off-by: Ralf Baechle

[PATCH] oprofile: Fix unnecessary cleverness

2006-06-26T16:58:17Z

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. Cc: Philippe Elie Cc: John Levon Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[MIPS] Fix modpost warning: Rename op_model_xxx to op_model_xxx_ops.

2006-06-05T23:15:11Z

The modpost uses a whitelist for commonly used suffix on checking the section mismatch. Adding "_ops" suffix to op_modex_xxx get rid of this modpost warning.
