Compressed texture don't work properly with i915tex, texcmp is really broken...

initial attempt at fixing compressed textures

This is my initial attempt at fixing compressed textures, it mainly illustrates
that I've no clue about the mipmap tree and region coding,

It crashes on my test system in the memcpy case I added..

Comment 2 Dave Airlie 2006-11-09 16:36:50 UTC

okay I've checked in the fixes for this into the i915tex branch it appears to
work well enough for all texcmp and my own application... 

I've just implemented GetCompressedTexImage and TexImage2D for compressed, I'm
not really sure how to implement SubTexImage and if someone uses that for
compressed textures I'd be pleasantly surprised..
