From 3525844d483bfb2236c1dd00f7a490297721ef78 Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Thu, 28 Jul 2022 11:42:44 +0530 Subject: [PATCH] drm/amdgpu: Use single copy per SDMA instance type (v2) v1: Only single copy per instance type is required for PSP. All instance types use the same firmware copy. (Lijo) v2: Apply the change into amdgpu_sdma_init_microcode() due to rebase.
