[Xen-devel] [PATCH v1] Increase framebuffer size to todays standards

[Olaf Hering <olaf@xxxxxxxxx>]

My notebook reports a display size of 1920x1080:

(XEN) vesafb: framebuffer at 0xd0000000, mapped to 0xffff82c000201000, using 
8128k, total 8128k
(XEN) vesafb: mode is 1920x1080x32, linelength=7680, font 8x16
(XEN) vesafb: Truecolor: size=8:8:8:8, shift=24:16:8:0

The hardcoded values feel arbitrary, so just bump them to fix my system.
The filters for notebooks at https://geizhals.eu/ indicate the upper
limit could be even larger, like 3840x2160.

Fixes commit e7cb35e8b1b8f872d906800c72f92f10d701f79c ("xen: introduce a 
generic framebuffer driver")
