[okl4-developer] PMCs

[Peter Nguyen]

Hi,

In using the Pentium architecture for OKL4, does anyone know how to  
get the PMCs working in terms of generating a performance monitoring  
interrupt? I am able to activate the counters, but when an overflow  
occurs, nothing happens. I've tried switching execution to use the  
APIC code, but that doesn't seem to work at all. I suspect the kernel  
debugger uses it although only to print the values of registers rather  
than utilising the performance monitoring facilities at all.

Any suggestions would be great.
