From: Flora Cui Date: Sat, 9 Dec 2017 04:08:46 +0000 (-0500) Subject: drm/amdkfd: Update number of compute unit from KGD X-Git-Tag: v4.16-rc1~96^2~16^2~18 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=f7ce2fade6e143a333dc51d84f2080738d6831bf;hp=4248bd0b102ae832cddf961b94a125385a2dfc92;p=linux.git drm/amdkfd: Update number of compute unit from KGD Overwrite the active simd_count from KGD at driver loading time. This is based on assumption that register GC_USER_SHADER_ARRAY_CONFIG won’t get changed. V2: remove the incorrect simd_count reported at loading module.
