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).

Looks like the problem was we weren't passing the depth to the render
target as expected, so the chip would wedge. Fixes GPU hang in
occlusion-query-discard.
Bug #30097

This is required by the spec, so respect that.

Use rc_pair_ prefix for all pair instruction structs
Create a named struct for pair instruction args
Replace structs radeon_pair_instruction_{rgb,alpha} with struct
radeon_pair_sub_instruction. These two structs were nearly identical
and were creating a lot of cut and paste code. These changes are the
first step towards removing some of that code.

Bug #30208.
|
|
Can be reproduced with mesa/demos/src/tests/blitfb.
NOTE: This is a candidate for the 7.9 branch.

This reverts commit c32bac57ed445e48856d74113364287ed6e5cdd4
and silences the warning differently.
The _mesa_reference_texobj() function is called quite a bit and
we don't want to call valid_texture_object() all the time in non-
debug builds.
|
|
Silences the following GCC warning on Mac OS X.
x86/common_x86.c:58: warning: 'detection_debug' defined but not used
|
|
|
|
Fixes this GCC warning.
warning: missing initializer for member 'statevar_element::array_indexed'

Implement the pipe_rasterizer_state::sprite_coord_enable field
in the draw module (and softpipe) according to what's specified
in the documentation.
The draw module can now add any number of extra vertex attributes
to a post-transformed vertex and generate texcoords for those
attributes per sprite_coord_enable. Auto-generated texcoords
for sprites only worked for one texcoord unit before.
The frag shader gl_PointCoord input is now implemented like any
other generic/texcoord attribute.
The draw module now needs to be informed about fragment shaders
since we need to look at the fragment shader's inputs to know
which ones need auto-generated texcoords.
Only softpipe has been updated so far.

This function is executed outside _mesa_meta_begin/end(), that means
that e.g. _mesa_meta_Bitmap() clobbers the texturing state because it
changes the currently active texture object.
There's no need to bind the new texture when it's created, it's done
again later anyway (from setup_drawpix/copypix_texture()).

Otherwise, FEATURE_EXT_texture_sRGB was undefined.
This is (part of?) the fix for fd.o bug 30177.

Enable some extensions now that the needed tokens are defined in
GLES/glext.h and GLES2/glext.h. Update the prototype of MultiDrawArrays
now that the prototype of _mesa_MultiDrawArraysEXT has been updated.

fbHeight is 0 in this case
uncovered by changes in b0bc026c and should fix kernel rejecting command
streams after that commit
|
|
Include compiler.h for ASSERT symbol.
|

when setting negative integers to bitfields we could overwrite
other parts of it. So mask the value to be written correctly.
This is used quite often in the driver - hope it doesnt affect
performace or uncover behaviour relied before...
fixes strange effects when setting negative lodbias on evergreen
|
|
A number of other files had to be updated as well because const
qualifiers were added to the glMultiDrawArrays() function.
Also, GL_FIXED is now defined in glext.h.

Remove all FEATURE tests in mesa/drivers/common/. They are not needed
and the code looks better without them.
|
|
Add dummy static inline definitions to syncobj.h when FEATURE_ARB_sync
is 0, and remove most FEATURE_ARB_sync tests.
|
|
They were intended to be used to build OpenGL ES only DRI drivers, but
that never happened.
|
|
Note, BTW, that the Gallium implementation returns 0.5, which seems
to violate the GLSL spec, where it should return 0.0 instead.
Not sure whether changing it to 0 is correct or not.

This turns on if conversion and unlimited loop unrolling if control
flow is not supported.
NOTE: this will change the behavior of r300g and any other driver
that doesn't advertise control flow
