It was only implemented in the swrast driver and probably not used by
any applications. A modern app would use a dependent/chained texture
lookup in the fragment shader.
|
|
This was sometimes useful back when 16-bit framebuffers were prominent.
|
|
|
|
We don't need to call bind_arrays in the vbo module if the states
which the function depends on are not dirty.

This adds i965 support for GL_EXT_framebuffer_sRGB, it introduces a new
constant to say that the driver can support sRGB enabled FBOs since enabling
the extension doesn't mean the driver can actually support sRGB.
Also adds the suggested state flush in the core code suggested by Brian.
fix the ARB_fbo color encoding.

The extension is off by default.
First in a patchset that implements support for AMD_conservative_depth in
the compiler.
|
|
The _NEW_ACCUM flag was only set when changing the accumulation
buffer clear color and never used anywhere. Reclaim that dirty bit.
Clean up the definitions of the other dirty bit flags.
|
|
This adds the get/enable enums and internal gl_config storage
for this extension.
In theory this is all that is needed to enable this extension
from what I can see, since its not mandatory to implement the
features if you don't advertise the visuals or the fb configs.

Remove the redundant public _mesa_prim_name[] array.

Drivers should override the default range/precision info as needed.
No drivers do this yet.

This implements the extension by choosing a different set of texture
fetch functions when the texture parameter changes.

Add a bit in struct gl_extensions for OES_standard_derivatives, and enable
the bit by default. Advertise the extension only if the bit is enabled.
Previously, OES_standard_derivatives was advertised in GLES2 contexts
if ARB_framebuffer_object was enabled.

Place GL, GLES1, and GLES2 extensions in a unified extension table. This
allows one to enable, disable, and query the status of GLES1 and GLES2
extensions by name.
When tested on Intel Ironlake, this patch did not alter the extension
string [as given by glGetString(GL_EXTENSIONS)] for any API.

Right now this is just tweaking the current code to look at the table.
Choosing actually supported formats will come later.

System values are shader inputs which don't necessarily change from
vertex to vertex or fragment to fragment. gl_InstanceID and
gl_FrontFacing are examples.

This allows 16K x 16K 2D textures, for example, but we don't want to
allow that for 3D textures. The new gl_constants::MaxTextureMBytes
field is used to prevent allocating too large of texture image.
This allows a 16K x 32 x 32 3D texture, for example, but prevents 16K^3.
Drivers can override this limit. The default is currently 1GB.
Apps should use the proxy texture mechanism to determine the actual
max texture size.

DD_POINT_SIZE was broken for quite some time, and the only driver (r200) relying
on this no longer needs it.
Both DD_POINT_SIZE and DD_LINE_WIDTH have no users left outside of debugging
output, hence instead of fixing DD_POINT_SIZE setting just drop both of them -
there was a plan to remove tricaps flags entirely at some point.

It was in the middle of the lighting-related structures before.
Also add some info about field sizes in this structure.

The assumption is that all stages are the same program or that
varyings are passed between stages using built-in varyings.
|
|
ActiveProgram is the GL_EXT_separate_shader_objects state variable
used for glUniform calls. glUseProgram also sets this.

Previously _LinkedShaders was a compact array of the linked shaders
for each shader stage. Now it is arranged such that each slot,
indexed by the MESA_SHADER_* defines, refers to a specific shader
stage. As a result, some slots will be NULL. This makes things a
little more complex in the linker, but it simplifies things in other
places.
As a side effect _NumLinkedShaders is removed.
NOTE: This may be a candidate for the 7.9 branch. If there are other
patches that get backported to 7.9 that use _LinkedShader, this patch
should be cherry picked also.

Just always check for FLUSH_UPDATE_CURRENT and call Driver.BeginVertices
when necessary. By using the unlikely() macros, this ends up as
a 10% performance improvement (for isosurf, anyway) over the old,
complicated function pointer swapping.

__GLcontextModes is always only used as an implementation internal struct
at this point and we shouldn't install glcore.h anymore. Anything that
needs __GLcontextModes should just include the struct in its headers files
directly.

This adds proper support for the GL_ARB_shader_stencil_export extension
to the GLSL compiler. Thanks to Ian for pointing out where I need to add things.

this is needed to add support for stencil shader export.

EXT_texture_compression_rgtc
Change the name in the extension tracking structure to ARB (from EXT).
|
|
This is only used in the i915 driver where it provides little benefit
for very few applications that use it with fixed function TNL.
