* st/mesa: disable alpha-test, alpha-to-coverage, alpha-to-one for integer FBsMarek Olšák2016-10-191-1/+2
| | | | | | v2: rebased Reviewed-by: Brian Paul <[email protected]>
* st/mesa: only enable MSAA coverage options when we have a MSAA bufferBrian Paul2016-09-161-3/+5
| | | | | | | | | | | | | | | | | Regardless of whether GL_MULTISAMPLE is enabled (it's enabled by default) we should not set the alpha_to_coverage or alpha_to_one flags if the current drawing buffer does not do MSAA. This fixes the new piglit gl-1.3-alpha_to_coverage_nop test. ETQW is a game that enables GL_SAMPLE_ALPHA_TO_COVERAGE without MSAA. Shrubs along the side of roads were invisible because fragments with alpha < 0.5 were being discarded (zero coverage). v2: remove ctx->DrawBuffer != NULL check.

* st/mesa: completely rewrite state atomsMarek Olšák2016-07-301-4/+0
| | | | | | | | | | | | | | | | | | | | The goal is to do this in st_validate_state: while (dirty) atoms[u_bit_scan(&dirty)]->update(st); That implies that atoms can't specify which flags they consume. There is exactly one ST_NEW_* flag for each atom. (58 flags in total) There are macros that combine multiple flags into one for easier use. All _NEW_* flags are translated into ST_NEW_* flags in st_invalidate_state. st/mesa doesn't keep the _NEW_* flags after that. torcs is 2% faster between the previous patch and the end of this series. v2: - add st_atom_list.h to Makefile.sources Reviewed-by: Nicolai Hähnle <[email protected]>

* gallium: prepare for per-rendertarget blend enables, writemasks, blend funcsRoland Scheidegger2010-01-201-15/+15
| | | | | | | | GL 3.0 (EXT_draw_buffers2) and other APIs allow independent blend enables and write masks per render target, ARB_draw_buffers_blend (and other APIs) also allow independent blend functions. Things like dithering, logic ops however are not extended to be per rendertarget, that might be conceptually possible however it doesn't look like any API wants to expose this.
* mesa: implement per-buffer color maskingBrian Paul2009-12-291-4/+4
| | | | | | | | | | | This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0. The ctx->Color.ColorMask field is now a 2-D array. Until drivers are modified to support per-buffer color masking, they can just look at the 0th color mask. The new _mesa_ColorMaskIndexed() function will be called by glColorMaskIndexedEXT() or glColorMaski().

* gallium: implement CSO save/restore functions for use by meta operations ↵Brian2008-03-191-7/+5

* gallium: rework CSO-related code in state trackerBrian2008-03-111-30/+22
| | | | | | | | | | Use the code in cso_context.c rather than st_cache.c. Basically, binding of state objects now goes through the CSO module. But Vertex/fragment shaders go through pipe->bind_fs/vs_state() since they're not cached by the CSO module at this time. Also, update softpipe driver to handle NULL state objects in various places. This happens during context destruction. May need to update other drivers...

* Avoid redundant reallocation of the template.Zack Rusin2007-09-191-2/+2
| | | | | | cso already allocated the template for us. Returning 0 means we have no driver specific representation and just want the template on the bind.
* Redo the cso cache to map driver data in a lot more pleasing way.Zack Rusin2007-09-191-4/+4
| | | | | | Drivers can now create whatever they want from the state template. We use cso_state object to store the template (necessary during lookups), and the driver data. Convert blend state to the new semantics.
* Implementing a better hash, removing state_tracker dependency from the cache.Zack Rusin2007-09-181-2/+3
| | | | | Replacing mesa's main hash with one that handles collisions, moving state_tracker related caching to the state tracker to keep cso cache independent of it. Cleanups.
* First stab at immutable state objects (create/bind/delete)Zack Rusin2007-09-181-3/+8
| | | | | | | We want our state objects to be immutable, handled via the create/bind/delete calls instead of struct propagation. Only implementing the blend state to see how it would look like and work.

softpipe/state_tracker --> state_tracker/ softpipe/ --> pipe/ softpipe/generic --> pipe/softpipe/ I don't think pipe is a great name, but I disliked all the others too. Luckily it's fairly easy to rename with git, so this can be revisited later.
