From 6879c912d27be8fc2fb030ace1ed5f10c4a05044 Mon Sep 17 00:00:00 2001
From: Philip Cox <Philip.Cox@amd.com>
Date: Wed, 19 Jun 2019 15:27:44 -0400
Subject: [PATCH 2863/2940] drm/amdkfd: Add function to update grace period
Adding functions to save the iq_wait_time values into the DQM and init
time, and functions to update the grace period values. This will be
required for the suspend queues functionality.
