Subject: Re: [RFC PATCH 00/11] drm/i915: Expose OA metrics via perf PMU
Date: Fri, 8 May 2015 18:21:43 +0200 [thread overview]
Message-ID: <20150508162143.GQ27504@twins.programming.kicks-ass.net> (raw)
In-Reply-To: <1431008154-6833-1-git-send-email-robert@sixbynine.org>
So I've not yet went through the entire series; but I'm wondering if its
at all possible to re-use some of this work:
lkml.kernel.org/r/1428453299-19121-1-git-send-email-sukadev@linux.vnet.ibm.com
That's for a Power8 HV call that can basically return an array of
values; which on a superficial level sounds a bit like what this GPU
hardware does.
Let me read more of this..
