From 231d53923918f4a885e74da0a063dcbf1a4353e3 Mon Sep 17 00:00:00 2001 From: Sinclair Yeh Date: Tue, 13 Oct 2015 12:58:26 -0700 Subject: [PATCH] svga: Condition preemptive flush on draw emission On ultra high resolution modes, the preemptive flush flag can be set midway through command submission, a condition that cannot be recovered from a flush-retry, causing rendering artifacts. This patch prevents a preemtive_flush until a draw has been emitted.
