Changes in v3:
- Also change trace, which I forgot about
Changes in v2:
- No longer adds tessellation shaders
Currently each shader cap has FS and VS versions.
However, we want a version of them for geometry, tessellation control,
and tessellation evaluation shaders, and want to be able to easily
query a given cap type for a given shader stage.
Since having 5 duplicates of each shader cap is unmanageable, add
a new get_shader_param function that takes both a shader cap from a
new enum and a shader stage.
Drivers with non-unified shaders will first switch on the shader
and, within each case, switch on the cap.
Drivers with unified shaders instead first check whether the shader
is supported, and then switch on the cap.
MAX_CONST_BUFFERS is now per-stage.
The geometry shader cap is removed in favor of checking whether the
limit of geometry shader instructions is greater than 0, which is also
used for tessellation shaders.
WARNING: all drivers changed and compiled but only nvfx tested

The function was duplicated.

That is, remove pipe_context::draw_arrays, pipe_context::draw_elements,
pipe_context::draw_arrays_instanced,
pipe_context::draw_elements_instanced,
pipe_context::draw_range_elements.

Some drivers define a generic function that is called by all drawing
functions. To implement draw_vbo for such drivers, either draw_vbo
calls the generic function or the prototype of the generic function is
changed to match draw_vbo.
Other drivers have no such generic function. draw_vbo is implemented by
calling either draw_arrays and draw_elements.
For most drivers, set_index_buffer does not mark the state dirty for
tracking. Instead, the index buffer state is emitted whenever draw_vbo
is called, just like the case with draw_elements. It surely can be
improved.

Only for first RT at the moment, as there is no trivial way in galahad
to look at framebuffer state and (sadly) people don't usually calloc
their CSOs, so flags could be wrongly set.
On the other hand, of course, galahad will hopefully encourage more
people to calloc their CSOs. :3

Not quite copied from r300g. This is slightly more API-compliant.

Design decision. Bad API errors should never be silenced.
Of course, you can always not use galahad.
|
|
And remove the offending member to keep that from happening again.
|
|
Currently unconditional and causes segfaults.
|
|
Galahad is a sanity-checking layer meant to replace the crufty and
scattered sanity checks inside drivers with a robust, non-silenceable,
useful set of warnings and errors that can be used to keep misbehaving
state trackers from going unnoticed.
