Us poor souls who cross compile mesa want to be able to specify which pkg-config to pick, or at least just change one place.

Commit 617cdcd4c7b1cffb584c829c35bdf9c9bf04627b delayed the texel
buffer allocation until texture_combine() is called. But the
texel buffer is needed sooner in _swrast_texture_span() at line 649.

So easy to screw up with the crazy way GL manages them.
|
| |
|
|
|
|
|

With 1D array textures, we no longer agree between the GL information
about width/height/depth of a texture and how we lay out a miptree.
|
|
|
|
| |
This is just moving the code out with s/6/slices/.

This also fixes what was probably a bug in 1D arrays with border.

Until now, we've been treating 1D arrays as a single slice, and each
array slice is actually just a row of the 2D texture. While swrast
still stores them this way, hardware drivers think that 1D arrays have
actual separate slices not stored as contiguous rows.

The path for ->Data was failing to be called for the FBO draw offset
fallback, and also had mismatched compressed texture support code.
This drops the intel_prepare_render() in the blit path. We aren't
copying to/from a GL_FRONT buffer, so it doesn't matter.
|
|
|
|
|
|
| |
Too many separate functions each called from one location (in
different files). This code should all die soon when swrast starts
using MapTextureImage.
|
|
|
|
|
| |
Now that whole block that also lives in AllocTextureImageBuffer can go
away.

Before, we were only allocating these from our TexImage, so if the
texture image was set up in any other way (non-accelerated
glGenerateMipmaps()), they'd be missing or wrong.
|
|
|
|
|
| |
Now we can rely on Mesa core for uploads of data without introducing
an extra copy at validate time.
|
|
|
|
|
|
|
|
|
|
|
| |
Now that we can zero-copy generate the mipmaps into brand new
glTexImage()-generated storage using MapTextureImage(), we no longer
need to allocate image->Data in mipmap generate. This requires
deleting the drivers' old overrides of the miptree tracking after
calling _mesa_generate_mipmap at the same time, or the drivers
promptly lose our newly-generated data.

Both POW and INT DIV need a message length of 2; previously, we only
checked for POW.
Also, BRW_MATH_FUNCTION_INT_DIV_QUOTIENT_AND_REMAINDER has a response
length of 2; previously, we only checked for SINCOS. We don't use this
message, but in case we ever decide to, we may as well fix it now.
While we're at it, just move these computations into
brw_set_math_message, since they're entirely based on the function.
This fixes it for both brw_math and the old backend's brw_math_16.

Drivers implementing GLSL 1.30 want to do integer modulus, and until we
can stop generating code via ir_to_mesa, it's easier to make it silently
generate rubbish code. Multiply will do.

Classic compiler mistake. In the example below, the OMOD optimization
was combining instructions 4 and 10, but since there was an instruction
(#8) in between them that wrote to the same registers as instruction 10,
instruction 11 was reading the wrong value.
Example of the mistake:
Before OMOD:
4: MAD temp[0].y, temp[3]._y__, const[0]._x__, const[0]._y__;
...
8: ADD temp[2].x, temp[1].x___, -temp[4].x___;
...
10: MUL temp[2].x, const[1].y___, temp[0].y___;
11: FRC temp[5].x, temp[2].x___;
After OMOD:
4: MAD temp[2].x / 8, temp[3]._y__, const[0]._x__, const[0]._y__;
...
8: ADD temp[2].x, temp[1].x___, -temp[4].x___;
...
11: FRC temp[5].x, temp[2].x___;

Source swizzles for transcendent instructions were being stored in the X
channel regardless of what channel the instruction was writing.
This was causing problems for some helper functions that were expecting
source swizzles to occupy channels corresponding to the instruction's
writemask. This commit makes transcendent instructions follow the same
convention as normal instructions for representing source swizzles.
Previous behavior:
LG2 temp[0].y, input[0].x___;
Current behavior:
LG2 temp[0].y, input[0]._x__;

From the EXT_transform_feedback spec:
Primitives can be optionally discarded before rasterization by calling
Enable and Disable with RASTERIZER_DISCARD_EXT. When enabled, primitives
are discared right before the rasterization stage, but after the optional
transform feedback stage. When disabled, primitives are passed through to
the rasterization stage to be processed normally. RASTERIZER_DISCARD_EXT
applies to the DrawPixels, CopyPixels, Bitmap, Clear and Accum commands as
well.
And the GL 3.2 spec says it applies to ClearBuffer* as well.

This reverts commit d631c19db47181129811080bfa772b210d762d4d.
The commit was broken, and ended up returning false all the time
because nobody in the world binds every single possible vertex array.
On further reflection, we don't want to discount stride == 0: This
function is just used for deciding to calculate whether to compute the
bonuds on the index, and there's no sense in computing index bounds
when stride == 0.
For the separate question of "how much data do I upload for this
vertex element?", the i965 driver was fixed to upload the data.
Fixes a regression of about 2x in 3DMMES, and most importantly, makes
Hammerfight playable.

Commit d631c19db47181129811080bfa772b210d762d4d avoided this problem
by forcing the driver to get the min/max index, but that commit was
broken, so just fix the driver problem (confusion between "do I need
to upload any data?" and "do I need the index bounds in order to
upload any data?").

Generally we're using fragment programs in all our drivers, so wasting

As innocuous as it seemed, ebca47a basically broke the world (e.g.,
>200 piglit regressions). In vec4_visitor::emit_block_move,
src->swizzle was expected to be BRW_SWIZZLE_NOOP before setting it to
a swizzle that would replicate the existing channels of the source
type to a vec4 (e.g., .xyyy for a vec2).
The original assertion seems to have been a little bogus. In addition
to being BRW_SWIZZLE_NOOP, src->swizzle might already be a swizzle
that would replicate the existing channels of the source type to a
vec4. In other words, it might already have the value that we're
about to assign to it.
