Fixes shadowtex.c. And an assert is added to catch this sooner next time.

This is somewhat nasty, but we need to do Y-tiled depth for FBO support.
May help with corruption and hangs since enabling texture tiling, and
since switching depth textures to Y tiled.
Fixes piglit depthtex.c on 965.
|
|
I was in the midst of fixing some blitting-with-Y-tiled issues when I
noticed this. Hopefully PBO usage will be a little more robust, as a
result.

The values 2147483648.0 and 4294967294.0 are too larget to be stored in single
precision floats. Forcing these to be singles causes bits to be lost, which
results in errors in some pixel transfer tests.
This fixes bug #22344.

stobj is now non-null for the default/null buffer object. Update the
test to check the buffer ID to see if it's a real buffer object.

Fixes regression in dd26899ca39111e0866afed9df94bfb1618dd363 that also
affected some PBO operations.

We could have mapped the wrong set of draw buffers. Noticed while looking
into a DRI2 glean ReadPixels issue.
|

|
This fixes a regression in region read performance that came in with the
texture tiling changes. Ideally we'd have an access flag coming in so we
could also use bo_map_gtt for writing, like we do for buffer objects.
Bug #22190

Fixes oglconform zbfunc.c and pxtrans-cidraw.c, at least.
|
|
The CALL_DrawArrays was leaking the clear's primitives into the display
list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which
doesn't appear to leak. Fixes piglit dlist-clear test.
|
|
I was rather confused when mesa_print_display_list didn't show any of
my glBegin()..glEnd(). Nothing but print_list appears to call
this function, so matching its behavior seems like a good idea.

pbo might be system buffer based or attached to another region. Call
intel_bufferobj_buffer to make sure pbo has a buffer of its own.

intel_bufferobj_subdata is called to migrate data from sys_buffer, and
it expects only one of buffer or sys_buffer is non-NULL.

need to pass target parameter to radeon_teximage/radeon_subteximage functions
otherwise mipmap generation for cube maps can't work (assert/segfault in
_mesa_generate_mipmap)

...rather than with linear interpolation. Modern hardware should use
perspective-corrected interpolation for colors (as for texcoords).
glHint(GL_PERSPECTIVE_CORRECTION_HINT, mode) can be used to get
linear interpolation if mode = GL_FASTEST.

Refcounting of the null/default buffer object isn't perfect yet so be
extra safe.

Tested with glean/texture_srgb and wine/d3d9 tests on RV535
|

This is handled entirely in core Mesa where the combiner state is converted
into a fragment program.

use the actual value set in the context
|
|
|
|
If GL context had e.g. tex0, tex2 and fog the VAPOutputCntl1 returned 0x104 instead of 0x124 - that meaned we're sending only 8 texcoords (instead of 12) which ended up in GPU hang.
|
|
We shouldn't use i variable for SWTCL_OVM_TEX because textures doesn't have to be enabled in "packed" order.
We could have tex1,tex3 and fog which would receive 7,9,8 OVM locations instead of 6,7,8.

RS_COL_FMT field is part of RS_IP_* reg not RS_INST_*

- when rewriting per component negate swizzle, first instruction should get not negated source
- KIL instruction ignores swizzles
TODO:
- tex instructions does not support saturation
- tex instructions cannot read from consant memory

Sending from VAP more texture coordinates than RS expects results in GPU hang.
Fixes BumpSelfShadow from DirectX8 SDK.

If the vertex program didn't write position attribute, the position invariant function would add necessary instructions, but the vertex position would be overwritten by artificial outputs insts added to satisfy fragment program requirements.
Fixes "whole screen is gray" problem for HW TCL path in sauerbraten when shaders are enabled, and whole slew of wine d3d9 tests.
|
|
|
|
|
|
If the vertex program wrote secondary color without primary color, the secondary color output register index would be 0 which resulted in overwriting vertex position in some cases.

Before, if a vertex shader's outputs didn't exactly match a fragment
shader's inputs we could wind up with invalid TGSI shader declarations.
For example:
Before patch:
DCL OUT[0], POSITION
DCL OUT[1], COLOR[1]
DCL OUT[2], GENERIC[0]
DCL OUT[3], GENERIC[0] <- note duplicate [0]
DCL OUT[4], GENERIC[2]
After patch:
DCL OUT[0], POSITION
DCL OUT[1], COLOR[1]
DCL OUT[2], GENERIC[0]
DCL OUT[3], GENERIC[1]
DCL OUT[4], GENERIC[2]
