Subject: [PATCH] drm/amdgpu: Set CP_HQD_PQ_CONTROL_RPTR_BLOCK_SIZE correctly in gfx_v8-v11.
Date: Mon, 16 May 2022 23:06:35 -0700	[thread overview]
Message-ID: <20220517060635.30481-1-ricetons@gmail.com> (raw)

From: Haohui Mai <ricetons@gmail.com>

Remove the accidental shifts on the values of RPTR_BLOCK_SIZE in gfx_v8-v11.
The bug essentially always programs the corresponding fields to zero
instead of the correct value.
