Modified: sys/i386/conf files.i386 options.i386
sys/i386/i386 machdep.c mem.c
sys/i386/include cpufunc.h
Added: sys/i386/i386 perfmon.c
sys/i386/include perfmon.h
Log:
Add support for Pentium and Pentium Pro performance counters.
(This code is as yet untested; to come after man page is written.)
This also adds inlines to cpufunc.h for the RDTSC, RDMSR, WRMSR, and RDPMC
instructions. The user-mode interface is via a subdevice of mem.c;
there is also a kernel-size interface which might be used to aid
profiling.
