* meta: Avoid FBO resizing/reallocating in decompress_texture_imageAnuj Phogat2012-02-151-1/+1
| | | | | | | | | | Reallocate/resize decompress FBO only if texture image width/height is greater than existing decompress FBO width/height. This is a candidate for stable branches. Signed-off-by: Anuj Phogat <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* meta: Add pixel store/pack operations in decompress_texture_imageAnuj Phogat2012-02-131-5/+3
| | | | | | | | | | | | | | | | | | | | This patch adds the pixel store operations in decompress_texture_image(). decompress_texture_image() is used in glGetTexImage() for compressed textures with unsigned, normalized values. It also fixes the failures in intel oglconform pxstore-gettex due to following sub test cases: - Test all mipmaps with byte swapping enabled - Test all small mipmaps with all allowable alignment values - Test subimage packing for all mipmap levels Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=40864 Note: This is a candidate for stable branches Signed-off-by: Anuj Phogat <[email protected]> Reviewed-by: Brian Paul <[email protected]>

* meta: Detect currently-unsupported integer CopyTexSubImage and complain.Eric Anholt2012-01-241-0/+5
| | | | | | | | | | | | | | | | This code is unprepared for handling integer (particularly, the baseFormat of the TexFormat comes out as GL_RGBA, not GL_RGBA_INTEGER, so the direct call of Driver.ReadPixels crashes due to the int vs non-int error checking not having happened). I'm frankly tempted to convert this code to MapRenderbuffer/MapTexImage rather than doing it as meta ops, now that we have that support. Improves the remaining crash in Intel oglconform for int-textures to just a rendering failure. NOTE: This is a candidate for the 8.0 branch. Reviewed-by: Brian Paul <[email protected]>

| | | | | | | | | | | | | | | During meta-operations (such as _mesa_meta_GenerateMipmap()), we need to be able to draw even if GL_RASTERIZER_DISCARD is enabled. This patch causes _mesa_meta_begin() to save the state of GL_RASTERIZER_DISCARD and disable it (so that drawing can be done during the meta-op), and causes _mesa_meta_end() to restore it.

* mesa: Add dd_function_table::PrepareExecBeginChad Versace2011-10-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This hook allows the driver to prepare for a glBegin/glEnd. i965 will use the hook to avoid avoid recursive calls to FLUSH_VERTICES during a buffer resolve meta-op. Detailed Justification ---------------------- When vertices are queued during a glBegin/glEnd block, those vertices must of course be drawn before any rendering state changes. To enusure this, Mesa calls FLUSH_VERTICES as a prehook to such state changes. Therefore, FLUSH_VERTICES itself cannot change rendering state without falling into a recursive trap. This precludes meta-ops, namely i965 buffer resolves, from occuring while any vertices are queued. To avoid that situation, i965 must satisfy the following condition: that it queues no vertex if a buffer needs resolving. To satisfy this, i965 will use the PrepareExecBegin hook to resolve all buffers on entering a glBegin/glEnd block. -------- v2: Don't add dd_function_table::CleanupExecEnd.

| | | | | | | | | | | If this flag is set, then _mesa_meta_begin/end will save/restore the state of GL_SELECT and GL_FEEDBACK render modes.

| | | | | | | | | | When saving the active program in _mesa_meta_begin, it was actually saving the fragment program instead.

* meta: fix broken sRGB mipmap generationBrian Paul2011-09-201-0/+28
| | | | | | | | | | If we're generating a mipmap for an sRGB texture we need to bypass sRGB->linear conversion. Otherwise the destination mipmap level (drawn with a textured quad) will have the wrong colors. If we can't turn of sRGB->linear conversion (GL_EXT_texture_sRGB_decode) we need to use the software fallback for mipmap generation. Note: This is a candidate for the 7.11 branch.
