The _Enabled field is the thing that takes into account whether
there's a stencil buffer. Tested with piglit glx-visuals-stencil.
|
|
When attaching a small mipmap level to an FBO, the original gen4
didn't have the bits to support rendering to it. Instead of falling
back, just blit it to a new little miptree just for it, and let it get
revalidated into the stack later just like any other new teximage.
Bug #30365.
|
|
This has always been ugly about our texture code -- object base/max
level vs intel object first/last level vs image level vs miptree
first/last level. We now get rid of intelObj->first_level which is
just tObj->BaseLevel, and make intelObj->_MaxLevel clearly based off
of tObj->_MaxLevel instead of duplicating its code (incorrectly, as
image->MaxLog2 only considers width/height and not depth!)

3D rendering to tiled textures was being done with non-tile-aligned offsets.
The G4X hardware has fields to let us support it easily and correctly, while
the pre-G4X hardware requires a path full of suffering, so we just fall back.

Noticed this with the fbotexture demo.

The fallback was introduced to fix bug #16697, but made the test it was
fixing run excessively long.

To do this, I had to clean up some of 965 state upload stuff. We may end
up over-emitting state in the aperture overflow case, but that should be rare,
and I'd rather have the simplification of state management.

Makes state emission into a 2 phase, prepare sets things up and accounts
the size of all referenced buffer objects. The emit stage then actually
does the batchbuffer touching for emitting the objects.
There is an assert in dri_emit_reloc if a reloc occurs for a buffer
that hasn't been accounted yet.

These fields are no longer indexed by shader output. Now, we just have
a simple array of renderbuffer pointers.
If the shader writes to gl_FragData[i], send those colors to the N
_ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or
the fixed-function color) to the N _ColorDrawBuffers.
A few more changes and simplifications can follow from this...
|
|
To do so, merge the remainnig necessary code from the buffers, blit, span, and
screen code to shared, and replace it with those.

This driver comes from Tungsten Graphics, with a few further modifications by
Intel.
