From 1b1f2fecb699bb4ccc3cb2fafe92950e9bdb39de Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Wed, 1 Aug 2018 16:00:52 +0200 Subject: [PATCH] drm/amdgpu: rework ctx entity creation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Use a fixed number of entities for each hardware IP. The number of compute entities is reduced to four, SDMA keeps it two entities and all other engines just expose one entity.
