Slight memory savings, but more importantly also avoids a potential NULL
dereference.

If we change the tiling on a buffer we need to flush it, the old
radeon_buffer.c code had this but it crossed streams when I ported to
radeon_drm_buffer.c and I missed it. Should fix some piglit regressions.

I've no idea about the comments that were in there, just pass
this down to the winsys.

And clean up the error checking code.

The bug is triggered by 41a87a43e11c664935349f938022d58d3e22da4e.
glBlitFramebuffer, for example, is an alias to the non-static
glBlitFramebufferEXT. We should define glBlitFramebuffer as an alias to
_dispatch_stub_NNN.

The entry point names, instead of the function name, should be used to
test if the entry point should be statically dispatched.

Fixing RGBA 4ub vertex colors.

Based on a patch from Tom Fogal.
|
|
Refactor the code into two helper functions which compute the bit mask
and shift terms for Z and stencil. Plus add a bunch of new comments to
explain everything.
|
|
no longer used after all statetrackers have been converted.
|
|
use cso fragment sampler views instead of sampler textures.
since we don't really change views, try to store sampler views instead
of the textures to avoid having to recreate views most of the time.

The assertion is checking that the low-order bits of offset are not
set. It does this by anding the inverted offset mask with the
offset. This is clearly intended to be a bit-wise "invert".
Fixes bug #25984.

I can't find the register bits for SRGB-aware blending and it's not even
exposed by fglrx so it's most probably not supported by hw.

We were mistakenly using the wrong data type for stencil values before.

The triangle rasterizer sets this field to indicate front/back-facing.
It gets passed into the generated fragment code as another parameter.
Used now for stencil front/back selection but will also be used for
fragment shaders in general (see TGSI_SEMANTIC_FACE).
With this commit two-sided stenciling mostly works but there's
still a bug or two...

Instead of passing an array, just pass two scalar values.

Fixes occasional bad tiles seen in some demos like progs/demos/reflect.c

Swizzling needs the destination surface in VRAM, but the subsequent
rendering operations making use of it are likely to not care. Fire the
ring after validation to leave the memory manager more room for
maneuvering.

nouveau reallocated the mipmap tree on every MIN_FILTER call to account
for mipmap change. We only need to do this if the texture does not fit
in the existing mipmap tree. This gives a big performance boost for a
game like bzflag which changes MIN_FILTER all the time for its font
rendering.

The default viewport is the window rectangle, which is set up by
_mesa_make_current(). To be able to do that we need to get the
window dimension (and buffers) first, so we have to call
intel_prepare_render() before we can call into _mesa_make_current().
Fixes #26676 and #26678.

The field was added in b8030c6561e019e079b5be2fe64ec804df4bfa03. This
fixes a NULL dereference in xdemos/texture_from_pixmap.

This is tested with demos found in progs/demos. However, only the DRI2
path is tested.
