[PATCH 6.11 550/695] drm/amdgpu: Fix selfring initialization sequence on soc24

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

 



6.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Belanger <david.belanger@xxxxxxx>

commit 03b5038c0ad069380fab7e251d2bf3f1540d20f4 upstream.

Move enable_doorbell_selfring_aperture from common_hw_init
to common_late_init in soc24, otherwise selfring aperture is
initialized with an incorrect doorbell aperture base.

Port changes from this commit from soc21 to soc24:
commit 1c312e816c40 ("drm/amdgpu: Enable doorbell selfring after resize FB BAR")
