From b1b9a04abd4cc461e507091fadea866788d4a60a Mon Sep 17 00:00:00 2001

From: Alon Levy <alevy@redhat.com>

Date: Wed, 12 Sep 2012 16:13:26 +0300

Subject: [PATCH 222/293] hw/qxl: tracing fixes

Add two new trace events:

qxl_send_events(int qid, uint32_t events) "%d %d"

qxl_set_guest_bug(int qid) "%d"

Change qxl_io_unexpected_vga_mode parameters to be equivalent to those

of qxl_io_write for easier grouping under a single systemtap probe.

Change d to qxl in one place.
