6 years agost/nine: Use perspective correction for ps depth fog
Axel Davy [Thu, 16 Aug 2018 14:29:31 +0000 (16:29 +0200)]
st/nine: Use perspective correction for ps depth fog

Emulate perspective interpolation of depth for programmable ps fog

ff ps fog uses position z, or 1/w depending on the ff
projection matrix set. This is according to public documents
found describing the algorithm and tests we made.

In the case of programmable ps, we used position's z,
which was sufficient to pass wine tests (which test shaders
don't set w).

Issue https://github.com/iXit/Mesa-3D/issues/315 showed
that this calculation was wrong.
Using perspective interpolation on z, that is using z * 1/w
seems to satisfy both this application and wine tests.

6 years agost/nine: Clamp RCP when 0*inf!=0

st/nine: Clamp RCP when 0*inf!=0

Tests done on several devices of all 3 vendors and
of different generations showed that there are several
ways of handling infs and NaN for d3d9.

Tests showed Intel on windows does always clamp
RCP, RSQ and LOG (thus preventing inf/nan generation),
for all shader versions (some vendor behaviours vary
with shader versions).
Doing this in nine avoids 0*inf issues for drivers
that can't generate 0*inf=0 (which is controled by
TGSI's MUL_ZERO_WINS).

For now clamp for all drivers. An ulterior optimization
would be to avoid clamping for drivers with MUL_ZERO_WINS
for the specific shader versions where NV or AMD don't
clamp.

LOG and RSQ being already clamped, this patch only
clamps RCP.

6 years agosvga: fix texture array layer index in transfer map
Charmaine Lee [Mon, 27 Aug 2018 19:07:42 +0000 (12:07 -0700)]
svga: fix texture array layer index in transfer map

In gallium, the layer index of a texture array to be mapped
is specified in the z component, whereas in svga device, the
index is specified in a separate argument.
Currently in svga_texture_transfer_map(), we explicitly modify
the z value in the base transfer map to 0 so the layer offset will not be
applied twice, but this causes problem when state tracker later
refers to the base transfer map and expects the slice index to be
specified in z (commit 463b0ea1f6762b7e0536cfadc4e384840af3e8e0).

To fix the problem, this patch makes a local copy of the box in
svga_transfer and modifies the z value in this copy instead.

Fixes spec@khr_texture_compression-astc piglit test crashes.
Fixes regression in the dma path with commit 1fdd3dd94a.
