This was already correct in the GEM code

This driver does no transformation of the gallium calls
going to the real driver, like the identity matrix. It is
intended to be the basis for transforming and/or debug
drivers like trace and rbug.
Authors of this patch are:
Michal Krol, orignal heavy lifting.
José Fonesca, object wrapping code stolen from trace.
Jakob Bornecrantz, put it all toghether and renamed a stuff.

I haven't fixed all the regressions yet, and it'll be easy to re-enable when
the known problems are fixed.
|
|
It's the last addressable byte, not the byte after the end of the buffer.
|
|
I noticed this when this MI_FLUSH showed up in IPEHR for the ut2004 hang.
Not setting the reserved bit didn't help, though.

Bug #19177.

Fixes assertion failure on norsetto shadow mapping demo.
|
|
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.
|
|
The real solution is to create a Makefile.template for xorg
drivers and use that here.

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)
|
|
use SGIS_generate_mipmap if EXT_fbo support (for manual mipmap generation)
is not available.

...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.
|
|
|
|
|
|
Test the effect of GL_PERSPECTIVE_CORRECTION_HINT on color interpolation.
|
|
|
|
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.

When the -arb option is specified we use GL_ARB_framebuffer_object intead
of GL_EXT_framebuffer_object.
For some vendors' OpenGL it's important to call the ARB entrypoints
instead of the EXT entrypoints to get correct behaviour. Use some
function pointer tricks to do this (instead of GLEW).
