A winsys is already a private object of a driver.
|
|
|
|
|
|
|
| |
Just let the hardware do it if it can and avoid drivers having to
check for the special case on each draw call.
v2: update the draw module
|
|
|
|
|
|
|
| |
Let the driver control interlaced or progressive
format of video buffers.

v2: handle the cap in r300 and r600 as well
Additional info for r600g:
The env var R600_GLSL130=1 enables GLSL 1.3.
Along with R600_STREAMOUT=1, it enables full GL 3.

For ARB_color_buffer_float. Most hardware can't do it and st/mesa is
the perfect place for a fallback.
The exceptions are:
- r500 (vertex clamp only)
- nv50 (both)
- nvc0 (both)
- softpipe (both)
We also have to take into account that r300 can do CLAMPED vertex colors only,
while r600 can do UNCLAMPED vertex colors only. The difference can be expressed
with the two new CAPs.

If draw isn't using llvm we can support vertex texture and integers,
These will be fixed up later, but for now allow this check to happen
at run-time.
v2: since 3e22c7a25321554a32fa6254485912fd53deff3a we can ask draw for a non-llvm
context. Just track if ask and set the vars accordingly. This probably isn't perfect but should cover the cases we care about.
v3: use debug option, restructure to store in screen, as suggested by Jakob.

This replaces the current code with an implementation compatible with
the new gallium interface. I've left some of the remains of the interface
intact so llvmpipe keeps building correctly, and I'll take a look at fixing
llvmpipe up later.

This introduces an unspecified interpolation paramter that is only allowed for
color semantics, so a specified GLSL interpolation will override the ShadeModel
specified interpolation, but not vice-versa.
This fixes a lot of the interpolation tests in piglit.

In the case where a front and back output are specified, the draw code will
copy the back output into the front color slot and everything is happy.
However if no front is specified then the draw code will do a bad copy (separate patch), but also the frag shader won't pick up the color as there there is
no write to COLOR from the vertex shader just BCOLOR.
This patch fixes that problem so if it can't find a vertex shader output
for the front color slot, it will go and lookup and use one for the back color
slot.

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

The motivation behind this is to add some self-documentation in the code
about how each CAP can be used.
The idea is:
- enum pipe_cap is only valid in get_param
- enum pipe_capf is only valid in get_paramf
Which CAPs are floating-point have been determined based on how everybody
except svga implemented the functions. svga have been modified to match all
the other drivers.
Besides that, the floating-point CAPs are now prefixed with PIPE_CAPF_.

Only i965g does not enable GLSL, but that driver has been unmaintained and

We want quad/pixel Z values to be interpolated exactly the same for
multi-pass algorithms. Because of how the optimized Z-test code is
written, we can't cull the first quad in a run even if it's totally
killed. See the comment for more info.
NOTE: This is a candidate for the 7.11 branch.

This moves the gallium interface for clears from using a pointer to 4 floats to a pointer to a union of float/unsigned/int values.
Notes:
1. the value is opaque.
2. only when the value is used should it be interpretered according to
the surface format it is going to be used with.
3. float clears on integer buffers and vice-versa are undefined.
v2: fixed up vega and graw, dropped hunks that shouldn't have been in
patch.

Pass an explicit surface format as we do with pipe_put_tile_rgba_format().
This fixes the piglit fbo-srgb-blit test. With GL_EXT_framebuffer_sRGB we
override the resource's format with an explicit format (linear vs. sRGB).
We need to do so both when getting and putting tiles.
