Subject: [PATCH] drm/amdgpu: Modify register access in sdma_v5_2 to use _SOC15 macros
Date: Fri, 4 Jun 2021 15:08:32 -0400	[thread overview]
Message-ID: <20210604190832.1611-1-rohit.khaire@amd.com> (raw)

In SRIOV environment, KMD should access SDMA registers
with RLCG if GC indirect access flag enabled.

Using _SOC15 read/write macros ensures that they go
through RLC when the flag is enabled.
