From dbfe85ea496728ccf7731601084853f760be77d7 Mon Sep 17 00:00:00 2001 From: Flora Cui Date: Tue, 20 Jun 2017 11:08:35 +0800 Subject: [PATCH] drm/amdgpu: Fix the exported always on CU bitmap MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Newer asics with 4 SEs are not able to fit the entire bitmask in the original field, use an array instead. v2: keep cu_ao_mask for backward compatibility.
