Subject: [Qemu-devel] [PATCH] Initialize the VMware VGA console after vga_init
Date: Tue, 08 Jul 2008 16:15:47 +0200	[thread overview]
Message-ID: <48737693.5030300@suse.de> (raw)

[-- Attachment #1: Type: text/plain, Size: 515 bytes --]

Hi,

while trying the -vmwarevga switch I stumbled across this nifty problem: 
vga_common_init calls vga_reset, which memsets the whole VGAState to 0. 
Unfortunately the console initialization code is before that, so it gets 
overwritten by 0 which breaks later on.

To circumvent this I reordered the console initialization to after the 
vga_init. I am not 100% sure if that's correct, but it works so far. 
Please double-check if this is the right approach.

Alex
