From: Ben Goz Date: Tue, 6 Jan 2015 09:32:13 +0000 (+0200) Subject: drm/amdkfd: fix runlist length calculation X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e1940fa4bfa32d86a771e300a3fd116c46878bf4;p=linux-beck.git drm/amdkfd: fix runlist length calculation The MAP_QUEUES packet length for Carrizo is different than for Kaveri. Therefore, we now need to calculate the runlist length with regard to the underlying H/W.
