Before, if we called glXMakeCurrent() to change a context's window binding
while an FBO was bound, we weren't updating the intel->driDrawable and
intel->driReadDrawable fields. This could cause us to dereference a null
pointer elsewhere.

The non-KMS interface is to blame here. In theory, a proper fix
could be produced that works for the KMS interface only, but it
require cleaning a lot of mess. Easier to just do it right in r300g.

If we deleted a currently bound texture, we were always reverting the texture
binding to the default 1D texture rather than the proper default texture.

lim x->0 log(x) = -inf so -FLT_MAX is a better approximation than 0
for LG2(0).

The renderType parameter to CreateContext() was never used. Also, it
was often passed as zero. Now when it's zero we check if the context
is RGBA or CI mode and set it accordingly.
Fixes bug 24211.

Once we've freed a miptree, we won't see any more state cache requests
that would hit the things that pointed at it until we've let the miptree
get released back into the BO cache to be reused. By leaving those
surface state and binding table pointers that pointed at it around, we
would end up with up to (500 * texture size) in memory uselessly consumed
by the state cache.

Since sqrt() is basically implemented in terms of RSQ/RCP we'll do a
divide by zero if x=0 and wind up with unpredictable results.
Now use CMP instruction to test for x<=0 and return zero in that case.

This silences tons of valgrind warnings in programs that don't call
glClear(), such as progs/demos/gamma.

Nasty bug when the surface is freed and another is allocated right on
top of it. The next time we set the fb state SP thinks it's the same
surface and doesn't flush, and when the flush eventually happens the
surface belongs to a completely different texture.

Build was broken by commit 9666529b5a5be1fcde82caadc2fe2efa5ea81e49
I'm not certain that this is entirely the correct fix since the demo
from bug #23774 seemed to work before the commit that broke the build.

The main issue is we didn't always have a gallium texture object with
enough space to store the to-be-generated mipmap levels. When that's
the case, allocate a new gallium texture and use st_texure_finalize()
to copy images from the old texture to the new one.
We also had the baseLevel parameter to st_render_mipmap() wrong.
|
|
Don't compute the st_texture_object::lastLevel field based on the texture
filters. Use the _MaxLevel value that core Mesa computes for us.
When called from the GenerateMipmap path, we'll use the lastLevel field
as-is.
