Re: [Xen-devel] Xenoprof: getting Oprofile out of timer mode?

["Andrei Lifchits" <alifchit@xxxxxxxxx>]

Hi Renato,

I'm using Xen unstable where you added builtin Xenoprof support (the
image is called xen-3.0-unstable.gz, I downloaded the source on Apr
13). Oprofile is built into the kernel.
I'm attaching the kernel and Xen logs to this email.

Thanks,
Andrei
