From: Jason Ekstrand Date: Tue, 21 Nov 2017 23:16:40 +0000 (-0800) Subject: anv/cmd_buffer: Sync clear values in begin_subpass X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8a3f086a42b643e33310ad8b9dbe63c57d6620b9;p=mesa.git anv/cmd_buffer: Sync clear values in begin_subpass This is quite a bit cleaner because we now sync the clear values at the same time as we do the fast clear. For loading the clear values into the surface state, we now do it once when we handle the LOAD_OP_LOAD instead of every subpass.
