From 4102a9e5325941223fbfa0a56175e9efb3d4385a Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Tue, 9 Feb 2016 12:05:30 -0500 Subject: [PATCH] drm/msm: add max-freq gpu param to uapi We need this in userspace for interpreting some of the perf ctrs. Note possibly not quite sufficient if we had some frequency mgmt approach other than race-to-idle. Not really sure what the best thing to do if we did. Although displaying results as a percentage of max frequence seems sensible(ish) if we did.
