Re: [Qemu-devel] Updated BGR vs. RGB vga patch...

["Leonardo E. Reiter" <lreiter@win4lin.com>]

Hi Thiemo,

the goal of my patch (and the original which I derived from) was to give 
the VGA device the ability to display correctly on BGR X servers.  Most 
likely this is for target-i386 emulation, such as for running Windows 
guests.  That's my need for the patch anyway.  In my case, I'm trying to 
get the colors to look right on a Sun Ray thin client served up from an 
x86_64 Linux box running the SRSS software from Sun (SunRay server 
basically.)  The emulator sessions run Windows 2000/XP, hence the need 
for VGA fixes.

If the O2's 24-bit display is similar to the Sun's (i.e. B/G/R, 24-bit 
depth, 32-bit pixel width), then the patch should fix the problem on the 
O2 as well when using PC hardware emulation (i.e. i386-softmmu)
