From: Samuel Pitoiset Date: Thu, 8 Nov 2018 10:16:45 +0000 (+0100) Subject: radv: fix GPU hangs when loading depth/stencil clear values on SI/CIK X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c472ad82e48e139e03ed28a7a98481814260d08e;p=mesa.git radv: fix GPU hangs when loading depth/stencil clear values on SI/CIK HTILE is supported on these chips, not sure how I missed that. This restores using PFP_SYNC_ME when LOAD_CONTEXT_REG is not used.
