Subject: [Qemu-devel] [PATCH] Fix VGA for MIPS Malta (big endian)
Date: Sun, 20 Jul 2008 16:28:44 +0200	[thread overview]
Message-ID: <48834B9C.8010102@weilnetz.de> (raw)

[-- Attachment #1: Type: text/plain, Size: 316 bytes --]

Hello,

this patch fixes the VGA display for MIPS Malta (big endian, 32 bit).

I have no tests for other big endian targets (32 or 64 bit).
Do they have a working VGA display (then my patch must be restricted
to MIPS and/or 32 bit), or do they show wrong pixel columns with current
Qemu trunk, too?

Regards
Stefan
