From 49e4d8cce2276cec0fcf56b7fa2be53f5501a78c Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 25 May 2017 11:58:40 -0700 Subject: [PATCH] i965: Move color rendering to the new resolve functions This also removes an unneeded brw_render_cache_set_check_flush() call. We were calling it in the case where the surface got resolved to satisfy the flushing requirements around resolves. However, blorp now does this itself, so the extra is just redundant.
