gallium: interface changes necessary to implement transform feedback (v5)
Namely:
- EXT_transform_feedback
- ARB_transform_feedback2
- ARB_transform_feedback_instanced
The old interface was not useful for OpenGL and had to be reworked.
This interface was originally designed for OpenGL, but additional
changes have been made in order to make st/d3d1x support easier.
The most notable change is the stream-out info must be linked
with a vertex or geometry shader and cannot be set independently.
This is due to limitations of existing hardware (special shader
instructions must be used to write into stream-out buffers),
and it's also how OpenGL works (stream outputs must be specified
prior to linking shaders).
Other than that, each stream output buffer has a "view" into it that
internally maintains the number of bytes which have been written
into it. (one buffer can be bound in several different transform
feedback objects in OpenGL, so we must be able to have several views
around) The set_stream_output_targets function contains a parameter
saying whether new data should be appended or not.
Also, the view can optionally be used to provide the vertex
count for draw_vbo. Note that the count is supposed to be stored
in device memory and the CPU never gets to know its value.
OpenGL way | Gallium way
------------------------------------
BeginTF = set_so_targets(append_bitmask = 0)
PauseTF = set_so_targets(num_targets = 0)
ResumeTF = set_so_targets(append_bitmask = ~0)
EndTF = set_so_targets(num_targets = 0)
DrawTF = use pipe_draw_info::count_from_stream_output
v2: * removed the reset_stream_output_targets function
* added a parameter append_bitmask to set_stream_output_targets,
each bit specifies whether new data should be appended to each
buffer or not.
v3: * added PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME for ARB_tfb2,
note that the draw-auto subset is always required (for d3d10),
only the pause/resume functionality is limited if the CAP is not
advertised
v4: * update gallium/docs
v5: * compactified struct pipe_stream_output_info, updated dump/trace

st/vega: Add support for per-channel alpha.
Drawing an image in VG_DRAW_IMAGE_STENCIL mode produces per-channel
alpha for use in blending. Add a new shader stage to produce and save
it in TEMP[1].
For other modes that do not need per-channel alpha, the stage does
MOV TEMP[1], TEMP[0].wwww

Per OpenVG 1.1. A new shader stage is added. It uses the first two
constants of the fragment shader for color transformation parameters.

st/vega: More flexible shader selection.
Divide bits of VegaShaderType into 6 groups: paint, image, mask, fill,
premultiply, and bw. Each group represents a stage. At most one shader
from each group will be selected when constructing the final fragment
shader.
