Without this windows xp guests set a 4 bits per pixel graphics mode.

With it we get the same behavior as with -vga std, that is a 32 bpp
graphics mode. This fits the size reported by hw/vga-pci.c .
---
Sending as RFC since I'm not sure if this is the right thing, nor that
it doesn't actually interfere with anything else. I did however do the testing
with and without mentioned in the patch comment and code comment.

It is the patch. An alternative that works with and without qxl driver, and fixes the problem
I reported, is to just change the VBE reported ram size to at most VGA_RAM_SIZE (== 8MiB).

Which qemu version?  Which seabios & vgabios version?

Windows xp booting in 4bit usually indicates VBE doesn't work at all, 
trying to enable vesafb in linux fails too then.

I havn't seen this for a *long* time.  Last time was a year or so back, 
while shaking out vgabios issues.  Especially I've never seen that with 
any qxl/spice stuff in upstream qemu.  Thats why I'm wondering where 
this comes from?

cheers,
    Gerd

qemu is the spice v36 branch with some unrelated patches.
seabios + vgabios upstream (seabios with 0x9000000 size hack).

I can retest with qemu upstream.

VBE is working fine - attached are the VBE calls made in three cases:
 * -vga std
 * -vga qxl with the normal 64 MB framebuffer.
 * -vga qxl with 8 MB framebuffer (reported) (it's identical to the first)

Note that this is all without the qxl driver working, but just with a windows xp install
with no qxl drivers.

I know yonit saw it too, I think she is using different versions of the above.
I don't know what changed.

Hmm, same here.

Same here, works fine.  XP with SP3 btw, maybe this makes a difference.
Can you try to boot linux with vga=0x314?

cheers,

tested tinycore, looks like it sets VBE correctly without my patch, to a 16 bit color mode,
right after boot:
VBE: write index=0x3 val=0x10
VBE: write index=0x1 val=0x320
VBE: write index=0x2 val=0x258
VBE: write index=0x5 val=0x0
VBE: write index=0x4 val=0x41

And later Xvesa sets a 24bit color mode:
VBE: write index=0x3 val=0x18
VBE: write index=0x1 val=0x400
VBE: write index=0x2 val=0x300
VBE: write index=0x5 val=0x0
VBE: write index=0x4 val=0x41

And this is all while reporting the whole 64 MiB
VBE: read index=0xa val=0x400

But this just means linux handles it fine. I don't have a non SP3 handy but I'll try
to get one to test later. Not a really pressing issue.
