We need to figure out if the compression format changes.
without this texcmp segfaults if you change format
enough times.
|
|
Converted r100 to use shared debug code with sed and fast compile check. New
code has compability layer so old debugging code doesn't have to be changed
all immidiatly.

- fix not respecting required hardware stride with compressedTexImage -
this fixes #22615.
- make sure correct stride is used in various places
- fix stored miptree never matching with a TexImage call with compressed
texture
- don't always store data with compressedtexsubimage at offset 0,
and actually use the supplied pixel data... (untested)
- make sure rows for compressed texture handling are rounded up not down
Note that trying to access stored compressed textures in hardware miptrees
from core mesa (get_compressed_teximage, swrast fallbacks) can't work correctly,
since RowStride isn't really set to anything useful, plus some places (at least
get_compressed_teximage) assume this data has native stride and no padding.

into r6xx-rewrite
This builds, but I get an assertion in radeonGetLock() due to
the drawable being null.
|
|
need to pass target parameter to radeon_teximage/radeon_subteximage functions
otherwise mipmap generation for cube maps can't work (assert/segfault in
_mesa_generate_mipmap)

Tested with glean/texture_srgb and wine/d3d9 tests on RV535
|
|
|
|
This gets the correct srclvl image map when uploading images to the new mipmap.
|
|
|
|
When a NULL value of pixels is passed to TexImage2D and
SGIS_generate_mipmap is enabled, don't try to generate the
mipmap tree: we don't have data yet for the texture and will
crash.

This might trip up some serious FBO users, will have to see, but
it avoids the slow paths for all the demos I have.

if you hit this you've already failed but we shouldn't crash
|

This replaces a miptree if it won't distrub anything else.
|
|
this makes compressed subimages work properly.
|
|
|
|
Since texture images are now stored in miptrees, we cannot usually
access them directly via the Data pointer.
So we wrap Mesa's implementation by map/unmap calls.
This crash was triggered by Sauerbraten, Piglit now contains a
regression test.

tested on r200, texcmp works. May need more verification
