This was already the case, but the generated (un)swizzling code was not
benefiting of that knowledge.

Collect the various driver limits in one place since.

This branch implemented dual representations of texture/drawing surfaces:
one in the conventional linear layout and the other the tiled layout which
is used by the fragment shader pipe. Per-tile flags indicate the layout
of each image tile. In many situations this lets us avoid converting
image data between the two layouts.

llvmpipe: convert points/lines to triangles with draw module
This isn't the most efficient way to render points/lines but it allows us
to run more tests.

llvmpipe: call llvmpipe_get_texture_tile() for depth/stencil
The returned pointer isn't used, but the tile status/layout info
gets updated. Helps to fix glReadPixels(DEPTH / STENCIL).

llvmpipe: add a special-case optimization to lp_surface_copy()
Be more efficient when copying tiled image to linear image.
Before, the fallback path was always converting the whole source image
to linear. Now we can convert just a sub region.

llvmpipe: convert tiled->linear upon PIPE_FLUSH_SWAPBUFFERS
If we know we're about to do a swapbuffers we should immediately
convert the tiled color tiles to linear instead of later in
llvmpipe_texture_unmap() since we can take advantage of threading/
parallelism here.

llvmpipe: checkpoint WIP: overhaul texture/surface mapping
Conversion between tiled and linear surfaces is working everywhere now.
The LP_TEXTURE_READ/READ_WRITE/WRITE_ALL flags let us avoid unnecessary
image layout conversions.
Still some loose ends, temporary/debug code, etc.
Need to implement tiled/linear conversion for depth/stencil images.

Incorrect rendering until the interpolation code generation is updated.
|
|
This is just a temporary change until we code generate the tile read/write
functions in runtime. The new code avoids an extra memcpy that exists in
u_tile.c functions, from which lp_tile_soa.c was originally based.
This achieves up to 5% improvement, particularly in frames with
little geometry overlap.
