ARB_fbo no longer disallows mismatched width/height on attachments
(shouldn't be any problem), mixed format color attachments (we only
support 1), and L/A/LA/I color attachments (we already reject them on
965 too). It requires Gen'ed names (driver doesn't care), and adds
FramebufferTextureLayer (we don't do texture arrays). So it looks
like we're already in the position we need to be for this extension.
Bug #27468, #32381.

Add ability to set the GLSL version used by the GLcontext by setting the
environment variable INTEL_GLSL_VERSION. For example,
env INTEL_GLSL_VERSION=130 prog args
If the environment variable is missing, the GLSL versions defaults to 120.

This is only used in the i915 driver where it provides little benefit
for very few applications that use it with fixed function TNL.

Fix commit e7087175f8a04f777403366fb34b58edd00f4d60. Move the reference to
GL_VERSION_2_1_functions to intel_extensions.c where it's available,
don't try to enable a non-existing extension and advertise 1.20 for all
intel chipsets, not just GEN4 and up.
|

Instead of using the invalid GL_ARB_shading_language_120 extension to
determine the GLSL version, use a new ctx->Const.GLSLVersion field.
Updated the intel and r600 drivers, but untested.
See fd.o bug 29910
NOTE: This is a candidate for the 7.9 branch (but let's wait and see if
there's any regressions).

The spec specifically sets the minimum MAX_SAMPLES at 1 to allow exposing
the extension on all implementations, so do so.
|
|
We could potentially do this on G45 as well, though the units are
different. On 965, the timestamp is tied to hclk, which would make
supporting it harder.

Shaves 400 bytes or so from i915_dri.so.

Saves another 600 bytes or so of code.

i830 does not (and cannot!) support the any of the non-default
GL_POINT_SPRITE_R_MODE_NV settings. i915 and i965 could, but
currently do not. In both cases it would require mucking about with
the fragment shader.

This really isn't supported at this point. GEM's been in the kernel for
a year, and the fake bufmgr never really worked.

Thanks to Chia-I Wu's changes to the extension function
infrastructure, we no longer have to tell the loader which extensions
the driver might enable. This means that intelInitExtensions will
never be called with a NULL context pointer. Remove all the NULL checks.

This enables the remap table in core. driInitExtensions is adapted to
use the remap table. All uses of extension_helper.h are replaced by
remap_helper.h. The chicken-egg problem of the DRI drivers is also
solved.
It is now also possible to pass NULL extensions to driInitExtensions.
It will cause driInitExtensions to map all known functions. This
functionality is used by software drivers and EGL_i915.

This is useful for enabling our GLSL testcases using the 2.0 entrypoints
even though we don't have full GL 2.0.
|
|
Other vendors have enabled ARB_fragment_shader as part of OpenGL 2.0
enablement even on hardware like the 915 with no dynamic branching or
dFdx/dFdy support. But for now we'll leave it disabled because we don't
do any flattening of ifs or loops, which is rather restrictive.
This support is not complete, and may be unstable depending on your shaders.
It passes 10/15 of the piglit glsl tests, but hangs on glean glsl1.
|
|
Since the TNL is all done in software anyway, it should be the same to
the user who's probably using ARB_vertex_program otherwise, but gives them
a nicer programming environment.
|
|
On the 965, we just drop the value into the primitive packet. On non-945,
we rely on the sw tnl code handling it.
|
|
|
|
We currently weasel out of supporting the timeout parameter, but otherwise
this extension looks ready, and should make the common case happy.

Passes glean's bufferObject test, and should provide good performance in the
cases applications are expected to use.

Passes glean's bufferObject test for this extension.

Passes tests/stencil_twoside and glean/stencil2.
|
|
It's all fallbacks anyway due to the DD_POINT_ATTEN fallback.
|
|
There doesn't appear to be any driver impact for enabling this, and
tests/prog_parameter passes.

|
No special driver changes are needed for this extension.

It's done in the Mesa GLSL compiler. The only part of it that might
matter in drivers is the centroid sampling option for MSAA.
|
|
Move the remaining extension string enables to intel_extensions.c.
Make sure that GL_NV_texture_env_combine4 is not enabled on i830.
