From e9062966428416da41ec5f9ace3d2ef58b3265b1 Mon Sep 17 00:00:00 2001 From: Alon Levy Date: Wed, 22 Aug 2012 11:16:25 +0300 Subject: [PATCH] qxl: add QXL_IO_MONITORS_CONFIG_ASYNC Revision bumped to 4 for new IO support, enabled for spice-server >= 0.11.1. New io enabled if revision is 4. Revision can be set to 4. [ kraxel: 3 continues to be the default revision. Once we have a new stable spice-server release and the qemu patches to enable the new bits merged we'll go flip the switch and make rev4 the default ] This io calls the corresponding new spice api spice_qxl_monitors_config_async to let spice-server read a new guest set monitors config and notify the client. On migration reissue spice_qxl_monitors_config_async.
