[PATCH v2 2/2] drm/amdgpu: Init VF's HDP flush reg offset early
Lijo Lazar
lijo.lazar at amd.com
Mon Aug 29 08:17:52 UTC 2022
Make sure the register offsets used for HDP flush in VF is
initialized early so that it works fine during any early HDP flush
sequence. For that, move the offset initialization to *_remap_hdp.
