* mesa: fix mipmap generation for immutable, compressed texturesRoland Scheidegger2015-09-251-21/+15
| | | | | | | | | | | | | | | | | | | | | If the immutable compressed texture didn't have the full mip pyramid, this didn't work, because it tried to generate mip levels for non-existing levels. _mesa_prepare_mipmap_level() would correctly handle this by returning FALSE if the mip level didn't exist, however we actually created the non-existing mip level right before that because we used _mesa_get_tex_image() before calling _mesa_prepare_mipmap_level(). It would then proceed to crash (we allocated the mip level, which is a bad idea on an immutable texture, but didn't initialize the values, leading to assertion failures or segfaults). Fix this by using _mesa_select_tex_image() instead and call it after _mesa_prepare_mipmap_level(), as that function will allocate missing mip levels for non-immutable textures already. This fixes a (2 year old) crash with astromenace which was hack-fixed in ubuntu packages instead: http://bugs.debian.org/718680 (I guess most apps do full mip chains - I believe this app not doing it is actually unintentional, always one level less than full mip chain...).

* mesa/formats: only do type and component lookup for uncompressed formatsNanley Chery2015-08-241-1/+1
| | | | | | | | | | | | Only uncompressed formats have a non-void type and actual components per pixel. Rename _mesa_format_to_type_and_comps to _mesa_uncompressed_format_to_type_and_comps and require callers to check if the format is not compressed. v2. include compressed format cases to avoid gcc warnings (Chad).

* mesa/main: Modify generate_mipmap_compressed to cope with float texturesNeil Roberts2014-08-121-5/+8
| | | | | | | | | Once we add BPTC texture support we will need to generate mipmaps for compressed floating point textures too. Most of the code seems to already be there but it just needs a few extra lines to get it to use GL_FLOAT instead of GL_UNSIGNED_BYTE as the type for the temporary buffers.

| | | | | | | | | | | | | | | | This helper function is used during mipmap generation to prepare space for the destination mipmap levels. This improves/fixes two things: 1. If the texture object was created with glTexStorage2D, calling _mesa_TexImage2D() to allocate the new image would generate INVALID_OPERATION since the texture is marked as immutable. 2. _mesa_TexImage2D() always frees any existing texture image memory before allocating new memory.

| | | | | | | | | | | | | The code was playing fast and loose with rowstrides, which meant that if a driver chose anything different for its alignment requirements, the generated mipmaps came out garbage. Unlike the uncompressed case, we can't generate mipmaps directly into image->Data, so by using TexImage2D we cut out most of the weird logic that existed to generate in-place into ->Data. The up/downside is that the driver recovery code for the fact that _mesa_generate_mipmaps whacked ->Data has to be turned off for compressed now. Fixes 6 piglit tests about compressed mipmap gen.
