Re: [Jikesrvm-core] performance counters for Linux/PPC?

[Feng Q. <fen...@ma...>]

Hi,

I asked the same question before. After some search online, it seems no kernel 
patch available for Linux/PPC to access performance counter registers. Under 
Linux/IA32, I am using PCL library with the JikesRVM. So far, it works nicely.
(one can get cache hits/misses, TLB misses, and so on).

It seems performance library counter on Linux/PPC is a missed functionarity not 
only for the JikesRVM users, also for Linux/PPC users. It would be nice if 
someone with kernel experience can come up with a patch.

Cheers,
Feng
