I fixed the only known bugs on r500 with 0222b2bd41.
Now there are no piglit regressions with Hyper-Z and all apps I tested seem
to work.
To summarize how it works:
- Only one process can use it at a time. This is a hardware limitation.
- The first process to clear a zbuffer gets the exclusive access to use
Hyper-Z.
- Compositors don't use any zbuffer, so they won't steal it, but some web
browsers do, so make sure there's no web browser running if you want your
game to use Hyper-Z.
- There's no need to restart an app which couldn't get the access to Hyper-Z.
Just quit the app which took it, the driver can turn it on for the other app
in the middle of rendering.
- If an app gets the access to Hyper-Z, it prints "radeon: Acquired Hyper-Z"
to stdout.
r300-r400:
Hyper-Z will be enabled by default on r300-r400 once sufficient testing is
done with piglit and Lightsmark at least.
Be sure to set the env var RADEON_HYPERZ and run piglit with parameters: -c 0
This fixes wrong rendering in Lightsmark and
the piglit/depthstencil-render-miplevels.
I think I fixed Hyper-Z. So far every app seems to work like a charm.
The border clamping code is unnecessary, since we don't care if a wrapped
coord value is -1 or <-1 (same for length vs. >length), in either case the
border handling code will mask out the offset and replace the texel value with
the border color.
Note that technically this is not entirely correct. Omitting clamping on the
float coords means that flt->int conversion may result in undefined values for
values of very large magnitude.
However there's no reason we should honor this here since:
a) we don't care for that for ordinary wrap modes in the aos code when
converting coords and the problem is worse there (as we've got only
effectively 24 instead of 32bits)
b) at least in some cases the clamping was done already in int space hence
doing nothing to fix that problem.
c) with sse2 flt->int conversion with such values results in 0x80000000 which
is just perfect (for clamp to border - not so much for the ordinary clamp to
edge).

This adds array (1d,2d) texture support to llvmpipe.

Support 1d and 2d array textures (including shadow samplers),
and (as a side effect mostly) also shadow cube samplers.
Seems to pass the relevant piglit tests both for sampling and rendering
to (though some require version overrides).
Since we don't support render target indices rendering to array textures
is still restricted to a single layer at a time.
Also, the min/max layer in the sampler view (which is unnecessary for GL)
is ignored (always use all layers).
