From 11e9bd3b65eb425197c417795a9ae5b634136291 Mon Sep 17 00:00:00 2001
From: Sanjay R Mehta <sanju.mehta@amd.com>
Date: Wed, 16 May 2018 16:01:15 +0530
Subject: [PATCH 3345/4131] drm/amdkfd: Adjust dequeue latencies and timeouts
Adjust latencies and timeouts for dequeueing with HWS and consolidate
them in one place. Make them longer to allow long running waves to
complete without causing a timeout. The timeout is twice as long as the
latency plus some buffer to make sure we don't detect a timeout
prematurely.
Change timeouts for dequeueing HQDs without HWS. KFD_UNMAP_LATENCY is
more consistent with what the HWS does for user queues.
