* mesa/meta: Support decompressing floating-point formatsNeil Roberts2014-08-121-2/+12
| | | | | | | | | | | | | Previously the Meta implementation of glGetTexImage would fall back to _mesa_get_teximage if the texturing is not using an unsigned normalised format. However in order to support the half-float formats of BPTC textures we can make it render to a floating-point renderbuffer instead. This patch makes decompression_state have two FBOs, one for the GL_RGBA format and one for GL_RGBA32F. If a floating-point texture is encountered it will try setting up a floating-point FBO. It will now also check the status of the FBO and fall back to _mesa_get_teximage if the FBO is not complete. Reviewed-by: Ian Romanick <[email protected]>
* mesa/meta: Add a partial implementation of CopyImageSubDataJason Ekstrand2014-08-111-0/+8
| | | | | | | | | | | | | | | | This provides an implementation of CopyImageSubData that works if both textures are uncompressed. This implementation works by using a combination of texture views and BlitFramebuffer. If one of the textures is compressed, it returns false and the driver is expected to provide a fallback. v2: Don't leak fbo's Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Juha-Pekka Heikkila <[email protected]> Reviewed-by: Neil Roberts <[email protected]> v3: Change glGen/DeleteTextures to _mesa_Gen/DeleteTextures

* meta: Add a meta implementation of GL_ARB_clear_textureNeil Roberts2014-07-231-0/+7
| | | | | | | | | | | | | | | | | | | | Adds an implementation of the ClearTexSubImage driver entry point that tries to set up an FBO to render to the texture and then calls glClearBuffer with a scissor to perform the actual clear. If an FBO can't be created for the texture then it will fall back to using _mesa_store_ClearTexSubImage. When used in combination with _mesa_store_ClearTexSubImage this should provide an implementation that works for all DRI-based drivers. However as this has only been tested with the i965 driver it is currently only enabled there. v2: Only enable the extension for the i965 driver instead of all DRI drivers. Remove an unnecessary goto. Don't require GL_ARB_framebuffer_object. Add some more comments. v3: Use glClearBuffer* to avoid having to modify glClearColor and friends. Handle sRGB textures. Explicitly disable dithering.

| | | | | | | | | The Meta implementation of glClearTexSubImage is going to want to ensure that dithering is disabled so that it can get a consistent color across the whole texture when clearing. This adds a state flag to easily save it and set it to the default value when performing meta operations. Reviewed-by: Topi Pohjolainen <[email protected]>

* meta: Split _swrast_BlitFramebuffer out of the meta blit path.Kenneth Graunke2014-05-191-1/+9
| | | | | | | | | | | | | | | | | | Separating the software fallbacks from the rest of the meta path (which is usually hardware accelerated) gives callers better control over their blitting options. For example, i965 might want to try meta blit, hardware blits, then swrast as a last resort. Splitting it makes that possible. This updates all callers to maintain the existing behavior (even in the few cases where it isn't desirable behavior - later patches can change that).

| | | | | | | | | | | | | | | | | | This code was broken in some odd ways before. Too much state was being saved, it was being restored in the wrong order, and in the wrong way. The biggest problem was that the pipeline object was restored before restoring the programs attached to the default pipeline.

| | | | | | | | | | | | | | | | | | | | | | The meta-ops _mesa_meta_Clear() and _mesa_meta_glsl_Clear() need to ignore the state of GL_SAMPLE_ALPHA_TO_COVERAGE, GL_SAMPLE_ALPHA_TO_ONE, GL_SAMPLE_COVERAGE, GL_SAMPLE_COVERAGE_VALUE, and GL_SAMPLE_COVERAGE_INVERT when clearing multisampled buffers. The easiest way to accomplish this is to disable GL_MULTISAMPLE during the clear meta-ops. Note: this patch also causes GL_MULTISAMPLE to be disabled during _mesa_meta_GenerateMipmap() and _mesa_meta_GetTexImage() (since those two meta-ops use MESA_META_ALL).
