[PATCH v3 0/2] use trace events and fix garbled output

From: Carwyn Ellis
Subject: [PATCH v3 0/2] use trace events and fix garbled output
Date: Sun, 6 Feb 2022 18:39:54 +0000

This patchset supersedes earlier submissions and incorporates feedback
from Laurent Vivier, Gerd Hoffmann and Philippe Mathieu-Daudé.

There are two patches addressing the following in the vmware vga display

 - use of fprintf to log debug output to STDERR

   This has been replaced with trace events.

 - garbled display due to lost display updates

   This prevents an issue that can cause garbled display output when
   a high number of screen updates are being requested.

   The queue is now flushed when it reaches capacity.

   The code traversing the queue when updates are being applied to the
   display has also been simplified, since we always start the traversal
   at the beginning of the queue to ensure that all updates are applied.

Carwyn Ellis (2):
  hw/display/vmware_vga: replace fprintf calls with trace events
  hw/display/vmware_vga: do not discard screen updates
