Re: [Xen-devel] Status of hardware performance counters in Xen

AFAIK nope.
I am also looking for a nice way to get hold of performance counters in Xen, but seems like its not making on to top of priority queue, perhaps one of us should try it or we can collaborate. :)
So, still the way to go is oprofile (xenoprofile).

 

Best Regards,

Subject: [Xen-devel] Status of hardware performance counters in Xen

Hello everyone,

I'm wondering what the current status of hardware performance counter
usability in Xen is. I see some old posts describing the diffculties of
virtualizing hardware counters within dom0 and the domUs, but not much else.

Have they been implemented or are they in the process of being implemented? Or
are there no future plans for implementation? Any help would be appreciated.

My platform would be Xen with Solaris x86 as the dom0 (xVM) and Solaris or
Linux as the domUs.

Thanks,
Viren
