I've noticed an issue with the i810 chipset that I'm wondering if anyone
can shed light on it..
I've it narrowed down to the fact that the texture upload code never gets
called for my texture, so the card doesn't know what to display, hence it
displays white space.
To repeat - get an i81x (may be an issue on i830 also.. )
get texture demo from Mesa-5.0
take wrs_logo.rgb from Mesa-5.0 and use xv to make it 1024x864 and save
it,
convert to a pnm,
run texture with the image file...
Now if you've got your VideoRAM setting set to 16384 you get white space,
if you set the VideoRAM setting to 18000 the image displays...
So I know 16384 is plenty of VideoRAM so why the whitespace?
What's the maximum texture size reported by 'glxinfo -l'? My guess is
that it's less than 1024*1024. If that's the case, when glTexImage is
called, it probably returns an error, and you get a white texture. :)
