From 2a1ac5ba9080d4e86e597fb287f6992a9511b90c Mon Sep 17 00:00:00 2001 From: Akhil P Oommen Date: Thu, 18 Nov 2021 15:50:29 +0530 Subject: [PATCH] drm/msm: Increase gpu boost interval Currently, we boost gpu freq after 25ms of inactivity. This regresses some of the 30 fps usecases where the workload on gpu (at 33ms internval) is very small which it can finish at the lowest OPP before the deadline. Lets increase this inactivity threshold to 50ms (same as the current devfreq interval) to fix this.
