As the value of ring->me has changed with gfx version, the code logic
is not repeat, I suggest keep the origin way to assign ref_and_mask.
I accept your suggestion of add params check, alignment mismatch and
delete the unused variable "usepfp".
Thanks,
Lijo

Subject: Re: [PATCH v3] drm/amdgpu: fix mes packet params issue when
flush hdp.
On 12/9/2025 1:08 PM, chong li wrote:
v3:
Unify the get_ref_and_mask function in amdgpu_gfx_funcs, to support
both GFX11 and earlier generations
v2:
place "get_ref_and_mask" in amdgpu_gfx_funcs instead of amdgpu_ring,
since this function only assigns the cp entry.
v1:
both gfx ring and mes ring use cp0 to flush hdp, cause conflict.
use function get_ref_and_mask to assign the cp entry.
reassign mes to use cp8 instead.
