From 8830e9f0cac2df7c8a1ae09086f27d8eb9bc80bd Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Tue, 28 Jan 2020 12:49:30 +0100 Subject: [PATCH] svga: Avoid discard DMA uploads Newer versions of the device code will make discard DMA uploads sub-optimal. Disable them for guest-backed aware code, where we previously had them conditionally enabled.
