The texmem.c interface is wildly messed up it really wants to own the objects
so let it, pain in the ass but this code should work a lot better now
|
|
This reverts commit 5325f8624093bb1ec30d581b4ff64218ceab99f9.

the destroy path was doing bad things with structure names, make it do less
bad things, use container_of instead
|
|
|
|
this is just more code cleanup for old dead code
|
|
|
|
this is whole texture dirty bit is probably not needed with the current
codebase, need to revisit
|
|
This replaces a miptree if it won't distrub anything else.
|
|
|
|
The radeon legacy code want to cleanup not free the texture obj,
so export a function to do that and wrap it.
|
|
this makes compressed subimages work properly.
|
|
|
|
You don't need libdrm_radeon for the legacy driver to build,
only for the experimental mm/cs paths.
|
|
Since texture images are now stored in miptrees, we cannot usually
access them directly via the Data pointer.
So we wrap Mesa's implementation by map/unmap calls.
This crash was triggered by Sauerbraten, Piglit now contains a
regression test.

The mip tree creation would crash if the first baselevel image to be uploaded
was not the positive-x image.
Found with Sauerbraten, also added a regression test to Piglit.

R3xx/R5xx fragment program texture constants must come from a hardware
register instead of the constant file, so we redirect if necessary during
the native rewrite phase.
The symptoms of this bug started appearing when the Mesa fixed function
texenvprogram code started using STATE_CURRENT_ATTRIB constants for
texture coordinates when the corresponding attributes were constant across
all vertices.

Move the is_boolean/integer_type() calls out of the loops.
Move the is_sampler_type() function near the bool/int functions.
Add a bunch of comments.

We were off by one when checking for too many uniform values.
|
|
If the vertex shader writes to a varying array with a variable index,
mark all the elements of that array as being written.
For example, if the vertex shader does:
for (i = 0; i < 4; i++)
gl_TexCoord[i] = expr;
Mark all texcoord outputs as being written, not just the first.
Linking will fail if a fragment shader tries to read an input that's not
written by the vertex shader. Before this fix, this linker test could fail.
|

Obviously, the color of fragments produced by DrawPixels is not constant,
even if the current vertex array / vertex program state indicates that the
color for normal rendering will be constant. Therefore, we need to override
certain optimisations that have been added to texenvprogram.c

Old limit was 256. Note that no arrays are declared to this size.
The only place we have to be careful about raising this limit is the
prog_src/dst_register Index bitfields. These have been bumped up too.
Added assertions to check we don't exceed the bitfield in the future too.

Note: the default value for EmitCondCodes is FALSE. This means the GLSL
compiler will emit code like this:
SEQ TEMP[0].x, A, B;
IF TEMP[0].x;
...
ENDIF
But if EmitCondCodes is TRUE, condition codes will be used instead:
SEQ.C TEMP[0].x, A, B;
IF (NE.xxxx);
...
ENDIF
|
|
The default for EmitCondCodes got flipped when gallium-0.2 was merged.
This fixes GLSL if/else/endif regressions.
Drivers that use GLSL should always explicitly set the flag to be safe.

Previously, the prog_instruction::Data field was used to map original Mesa
instructions to brw instructions in order to resolve subroutine calls. This
was a rather tangled mess. Plus it's an obstacle to implementing dynamic
allocation/growing of the instruction buffer (it's still a fixed size).
Mesa's GLSL compiler emits a label for each subroutine and CAL instruction.
Now we use those labels to patch the subroutine calls after code generation
has been done. We just keep a list of all CAL instructions that needs patching
and a list of all subroutine labels. It's a simple matter to resolve them.
This also consolidates some redundant post-emit code between brw_vs_emit.c and
brw_wm_glsl.c and removes some loops that cleared the prog_instruction::Data
fields at the end.
Plus, a bunch of new comments.

This doesn't effect correctness, but we were emitting an extraneous ADD.

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.
