From b5cc6e32baa9d98d50debe23229b303f89fe84f1 Mon Sep 17 00:00:00 2001 From: Anthony Liguori Date: Fri, 18 Dec 2009 08:08:10 +1000 Subject: VMware VGA: Only enable dirty log tracking when fifo is disabled This patch enables dirty log tracking whenever it's needed and disables it when it is not. We unconditionally enable dirty log tracking on reset, restart dirty log tracking when PCI IO regions are remapped, and disable/enable it based on commands from the guest.
