Subject: drm/amdgpu: Enable F32_WPTR_POLL_ENABLE in mqd
From: Ruili Ji <ruiliji2@xxxxxxx>
commit 21a550de5faf9f54013334c9a6a7643b8fd80b36 upstream.
This patch is to fix the SDMA user queue doorbell missing issue on
SDMA 6.0. F32_WPTR_POLL_ENABLE has to be set if doorbell mode is
used. Otherwise ringing SDMA user queue doorbell can't wake up
system from gfxoff.
