[PATCH 12/18] drm/amdgpu:use formal register to trigger hdp invalidate

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Yeah, but Vega10 has UVD7 and in uvd_v7_0.c we have:

> static void uvd_v7_0_ring_emit_hdp_invalidate(struct amdgpu_ring *ring)
> {
>         amdgpu_ring_write(ring, PACKET0(SOC15_REG_OFFSET(HDP, 0, 
> mmHDP_DEBUG0), 0));
>         amdgpu_ring_write(ring, 1);
> }

That should probably be fixed as well.

Regards,
Christian.
