Subject: [Qemu-devel] [PATCH] edid: add xmax + ymax properties
Date: Fri,  7 Jun 2019 10:34:29 +0200	[thread overview]
Message-ID: <20190607083429.31943-1-kraxel@redhat.com> (raw)

Add new properties to allow setting the maximum display resolution.
Resolutions larger than that will not be included in the mode list.
In linux guests xrandr can be used to list modes.

Note: The existing xres and yres properties set the preferred display
resolution, i.e. the mode should be first in the mode list and guests
should use it by default.
