MIPS performance counters

MIPS performance counters

[Chris Dearman]

Hi,
  A few days ago someone (sorry, I deleted the mail...) was asking about
support for MIPS performance counters.  Some time ago I ported Mikael
Pettersson's perfctr (http://www.csd.uu.se/~mikpe/linux/perfctr)
driver to 2.2.12 and used that to profile programs running on an
RM7000.  This driver has a reasonably generic interface and supports per
process profiling.
 Unless anyone can suggest a better starting point I'll have a look at
putting this into 2.4.14.

	Regards
		Chris

Aside a few details I liked the proposal posted by Keith Owens.  I guess
his proposal is however more aimed at 2.5 than at 2.4 so for 2.4 your
proposal is probably a good thing.
