This prevents the mystery blank window if, for example, glxgears is
resized larger than 2048 wide on 915. Since the Intel drivers in Mesa
7.6 lack GTT mapped fallbacks, the performance is a slideshow at
best. On Mesa 7.7 and later the performance is much better.

makes testing other things easier - does not hang the card
TODO: enable TEX dependency tracking in vertex programs
|
|
First time around render targets are not enabled yet (done in
r700SendRenderTargetState) so blend state is not emitted for any targets.
Affects first glClear in some mesa tests.
As a quick fix reorder state emit so that target is set first

i830 does not (and cannot!) support the any of the non-default
GL_POINT_SPRITE_R_MODE_NV settings. i915 and i965 could, but
currently do not. In both cases it would require mucking about with
the fragment shader.

Support still isn't completely correct, but it's better. piglit
point-sprite now passes. However, glean's pointSprite test fails. In
that test the texture on the sprite is somehow inverted as though
GL_POINT_SPRITE_COORD_ORIGIN were set to GL_LOWER_LEFT. i915 hardware
shouldn't be able to do that!
I believe there are also problems when not all texture units have
GL_COORD_REPLACE set. The hardware enable seems to be all or nothing.
Fixes bug #25313.

Thanks to Intel code which I've just stolen pretty much as usual.
This fixes fdo bug 22851 which is a dri1 regression since rewrite.

This fixes an assertion failure in _mesa_MapBufferARB.

Too bad I didn't realize earlier how easy this could be...

This reverts commit 284a7af274bc148f112bd0ebb40583923ee26b49.
This breaks kde desktop effects. See fdo bug 24131

The cube map array index arg is always present.
|
|
Instead of doing math based on the (broken for VBO && offset != 0)
input->count number, just use the BO size. Fixes assertion failure in ETQW.
|

This didn't work for quad/quadstrips at all, and for all other primitive types
it only worked when they were unclipped.
Fix up the former in gs stage (could probably do without these changes and
instead set QuadsFollowProvokingVertexConvention to false), and the rest in
clip stage.

Previously, we'd load linearly from ParameterValues[0] for the constants,
though ParameterValues[1] may not equal ParameterValues[0] + 4. Additionally,
the STATE_VAL type paramters didn't get updated.
Fixes piglit vp-constant-array-huge.vpfp and ET:QW object locations.

These are needed for HiZ which is not currently used and
the _BASE reg requires a reloc which is not currently supported
in the drm.
|

The code was assuming ctx->DrawBuffer == ctx->ReadBuffer.
Passing the pixmap is simpler and better.
Fixes a potential segfault.

This fixes the second part of bug 23552.

Use src->draw_offset intead of zero. Zero usually worked, except when
the src renderbuffer is actually a texture mipmap level higher than zero.
Fixes progs/test/blitfb.c test.

Bug #24734.
|

|

This reverts commit 8810b8f67135185d1044746bb861fe2ff997626c.
It turns out the i965 driver uses the intel->Fallback field as a boolean,
not as a bitmask. The intelFallback() function is a no-op in the i965
driver. It would have been nice if there were some comments about this.
I'll fix that next...

Need to push texture state and polygon state too.
Fixes rendering glitches seen in progs/demos/engine when changing
the rendering mode (wireframe, texture modes).
This makes bitmap rendering a little slower, unfortunately.
|
|
By just using offsets, we confused the hardware's tiling calculations,
resulting in failures in miptree validation and blit clears.
Fixes piglit fbo-clearmipmap.
Bug #23552. (automatic mipmap generation)
|
|
Per the GLX spec, when changing rendering contexts, the old context
should first be flushed.
|
|
Setting intel->Fallback = 1 clobbered any fallback state that was already
set. Not sure where this hack originated (the git history is a little
convoluted). Define and use a new BRW_FALLBACK_DRAW bit instead. This
shouldn't break anything and could potentially fix some bugs (but no
specific ones are known).
