What is the outcome of this patch? I mean, does it actually fix something visible, instead of a potential problem?
[]
Anyone interested in this ? Is there a maintainer for x86emu ? The MAINTAINERS file in xorg-docs doesn't mention anything about it.
CCed: Adam Jackson
Adam, you seem to be the maintainer of the xorg vesa driver. I think this patch is closely related. Would you mind taking a look at it ?
I asked another question related to xorg vesa driver, also related to qemu, about it being unable to find available resolutions when run under qemu -- this: http://lists.x.org/archives/xorg-devel/2012-March/030037.html Is this 0x66 issue related to my question somehow? :)
Thanks,

x86emu in it's current state is unable to emulate correctly 16bit code that has been produced by GCC. This patch is an attempt to fix it. If this is what you want to know, no it doesn't fix something that has already been reported as working. It just adds more correctness to the emulator.

This question is vgabios specific. This patch concerns seabios VGA rom. I believe the reason why Xorg can't use a resolution superior to 1024x768 is because vgabios doesn't implement the 15h VBE function, and therefore doesn't expose a valid EDID block to Xorg. SeaBIOS VGA rom suffers from the exact same problem, and I already started a discussion on the mailing list in order to fix it. Have a look at: http://seabios.org/pipermail/seabios/2012-March/003470.html if you're interested. Still, this is unrelated to what this patch tries to achieve.
