* mesa: change ctx->Color.ColorMask into a 32-bit bitmaskMarek Olšák2018-02-041-33/+20
| | | | | | | | 4 bits per draw buffer, 8 draw buffers in total --> 32 bits. This is easier to work with. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | This only affects drivers that set DriverFlags.NewBlend. v2: - fix typo advanded -> advanced - return "enum gl_advanced_blend_mode" from _mesa_get_advanced_blend_sh_constant - don't call FLUSH_VERTICES twice Reviewed-by: Ian Romanick <[email protected]>

* mesa: Also track a remapped version of the color logic opIan Romanick2018-01-261-0/+20
| | | | | | | | | | | | | | | | | With the exception of NVIDIA hardware, these are is the values that all hardware and Gallium want. The remapping is currently implemented in at least 6 places. This starts the process of consolidating to a single place. v2: sed --in-place -e 's/color_logic_ops/gl_logicop_mode/g' $(grep -lr color_logic_ops src/) suggested by Brian. Added some comments about the selection of bit patterns for gl_logicop_mode and the GLenums. Suggested by Nicolai. Folded the GLenum_to_color_logicop macro into its only users.

| | | | | | | | | | | | | Add a proper check for feature support, and raise an invalid enum for GL_CLAMP_VERTEX/FRAGMENT_COLOR unconditionally in core profiles, since those enums were explicitly removed after the extension was promoted to core functionality (not in the profile sense) with OpenGL 3.0. This matches the behavior of the AMD closed source driver and fixes GL45-CTS.gtf30.GL3Tests.half_float.half_float_textures.

| | | | | | | | | | | Use a bitmask to indicate which color buffers are integer-valued, rather than a bool. Also, the old field was mis-computed. If an integer buffer was followed by a non-integer buffer, the _IntegerColor field was wrongly set to false. This fixes the new piglit gl-3.1-mixed-int-float-fbo test.

* Fix the initial value of glDrawBuffers for GLESNeil Roberts2014-03-121-1/+3
| | | | | | | | | | | | | | | | | | Under GLES 3 it is not valid to pass GL_FRONT to glDrawBuffers. Instead, GL_BACK has a magic interpretation which means it will render to the front buffer on single-buffered contexts and the back buffer on double-buffered. We were incorrectly setting the initial value to GL_FRONT for single-buffered contexts. This probably doesn't really matter at the moment except that presumably it would be exposed in the API via glGetIntegerv. When we switch to configless contexts this is more important because in that case we always want to rely on the magic interpretation of GL_BACK in order to automatically switch between the front and back buffer when a new surface with a different number of buffers is bound. We also do this for GLES 1 and 2 because the internal value doesn't matter in that case and it is convenient to use the same code to have the magic interpretation of GL_BACK.
