From 0fe78ffd13555bed86a41acf96cdc15ece961b0d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?S=C3=B8ren=20Sandmann=20Pedersen?= Date: Tue, 4 Sep 2012 10:14:48 -0400 Subject: [PATCH] qxl: Add set_client_capabilities() interface to QXLInterface This new interface lets spice server inform the guest whether (a) a client is connected (b) what capabilities the client has There is a fixed number (464) of bits reserved for capabilities, and when the capabilities bits change, the QXL_INTERRUPT_CLIENT interrupt is generated.
