Current practice is to start identifiers with "util_" instead of "u_".

This is a simple framework that handles splitting primitives in an
abstract way.
The user has to specify the primitive start, start index and count.
Then, it can ask the primitive splitter to "draw" a chunk of the
primitive, staying under a given vertex/index budget.
The primitive splitter will then call user-supplied functions to
emit a range of vertices/indices, as well as switch the edgeflag
on or off.
This is particularly useful for hardware that either has limits
on the vertex count field, or where vertices are pushed on a FIFO
or temporary buffer of limited size.
Note that unlike other splitters, it does not manipulate data in
any way, and merely asks a callback to do so, in vertex intervals.

This got lost during the rasterizer rewrite.

Single loops work, but nested loops do not.

It's bound to be useful elsewhere.

The shader caps need additional corrections.

ofs is in dwords, so need to shift it for registers.

In this case, we were incorrectly prioritizing PIPE_TRANSFER_DONTBLOCK over
PIPE_TRANSFER_UNSYNCHRONIZED.
This can lead to failure in the Mesa VBO draw paths that end up specifying
both, but don't expect map to fail (in particular, the problem manifested as
a leak of buffer objects in teapot with other changes).

Ooops, it wasn't supposed to be there.

It sometimes works, sometimes not. I guess we have the zmask offsets wrong.

Need to add a test for multi-hiz/zmask db in a single context.

- This can only be triggered when DEBUG_NOUVEAU_STATEOBJ is active.
- Also remove a redundant pointer assignment.

fixup exports from pixel shader for multi-cbs + depth buffer writing.
Still crashes GPU running any of the multi-buffer or depth writing
|
|
This enables GL2.1 and passes glean's texture_srgb test.
|
|
this enables GL_EXT_packed_depth_stencil. fbo-d24s8 passes
|
|
At least this seems to fix the glean maskedClear test.
|
|
This fixes fbo-readpixels piglit test, and adds support for swapping
the formats. Not all formats are correct yet I don't think.

Apparently they have always been broken, even before unification.
Fixes a lot of stuff, starting from morph3d and lighting in teapot
with textures disabled.

Simplify state handly by avoiding state allocation.
Next step is to allocate once for all context packet
buffer and then avoid rebuilding pm4 packet each time
(through use of combined crc) this would also avoid
number of memcpy.

On my rv530 at least HiZ is causing rendering issues in gears.

This implements fast Z clear, Z compression, and HiZ support for r300->r500
GPUs.
It also allows cbzb clears when fast Z clears are being used for the ZB.
It requires a kernel with hyper-z support.
Thanks to Marek Olšák <maraeo@gmail.com>, who started this off, and Alex Deucher at AMD for providing lots of hints.
v2:
squashed zmask ram size fix]
squashed r300g/blitter: fix Z readback when compressed]
v3:
rebase around texture changes in master - .1 fix more bits
v4:
migrated to using u_mm in r300_texture to manage hiz/zmask rams consistently
disabled HiZ when using OQ
flush z-cache before turning hyper-z off
update hyper-z state on dsa state change
store depthclearvalue across cbzb clears and replace it afterwards.

We only uploaded up to the highest offset a program would use,
and if the constant buffer isn't changed when a new program is
used, the new program is missing the rest of them.
Might want to introduce a "fill state" for user mem constbufs.
