2008-01-29[MIPS] Extend performance counter event field.Ralf Baechle
The latest draft version of the MIPS Architecture Specification extends the 6 bit event field by adding a directly adjacent 4-bit EventExt field for a total of 10 bits. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-12-06[MIPS] Oprofile: Fix computation of number of counters.Ralf Baechle
VSMP kernels will split the available performance counters between the two processors / cores. But don't do this when we're not on a VSMP system ... Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-10-19Combine instrumentation menus in kernel/Kconfig.instrumentationMathieu Desnoyers
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."

2006-06-26[PATCH] oprofile: Fix unnecessary clevernessMarkus Armbruster
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.

2006-06-06[MIPS] Fix modpost warning: Rename op_model_xxx to op_model_xxx_ops.Atsushi Nemoto
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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
