From 4ed75c3e525598ff1aa6aed09c419c73a4efd2f2 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Fri, 9 Mar 2018 14:29:26 +0100 Subject: [PATCH] drm/etnaviv: bump HW job limit to 4 The current limit of 2 leads to some GPU idle times, as the usual IRQ latency leads to up to 3 jobs getting signaled at once with some standard workloads. A larger HW job limit might lead to slightly worse QoS, but we accept that to not sacrifice GPU throughput in the common case.
