Subject: [PATCH 0/3] MIPS performance event support initial version
Date: Fri, 16 Apr 2010 00:38:31 +0800 [thread overview]
Message-ID: <1271349511.7467.419.camel@fun-lab> (raw)
This patch series implemented the low-level logic for the Linux
performance counter subsystem on MIPS, which enables the collection of
all sorts of HW/SW performance events based on per-CPU or per-task.
An overview of this implementation is as follows:
- Using generic atomic64 operations from lib.
- SMVP/UP kernels are supported (not for SMTC).
- 24K/34K/74K cores are implemented.
- Currently working when Oprofile is _not_ available.
- Minimal software perf events are supported.
Tests were carried on the Malta-R board. The mentioned cores and kernel
flavors were tested. For more information, please refer to the particular
patches.

- MIPS: use the generic atomic64 operations for perf counter support
- MIPS: adding support for software perf events
- MIPS: implement hardware perf event support
