* MIPS: Oprofile: Rename cpu_type from godson2 to loongson2Wu Zhangjin2009-11-021-1/+1
| | | | | | | | | | Unify the naming method between kernel and the user-space oprofile tool. Because loongson is used instead of godson in most of the places, we agreed to use loongson instead, which will simplify future maintenance.

* MIPS: Loongson: Add oprofile supportWu Zhangjin2009-09-173-0/+182
| | | | | | | | | | | | | | 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.

* Combine instrumentation menus in kernel/Kconfig.instrumentationMathieu Desnoyers2007-10-191-23/+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."

* [PATCH] oprofile: Fix unnecessary clevernessMarkus Armbruster2006-06-261-1/+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.

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!
