st/mesa: fix levels in initial texture creation

calim pointed out we were getting mipmap levels for array multisamples,
this didn't make sense. So then I noticed this function takes last_level
so we are passing in a too high value here.

I think this should fix the case he was seeing.

11 years agoglsl: Remove some unnecessary uses of error_emitted
Ian Romanick [Fri, 15 Mar 2013 21:27:22 +0000 (14:27 -0700)]
glsl: Remove some unnecessary uses of error_emitted

The error_emitted flag is used in semantic checking to prevent spurious
cascading errors.  For example,

void foo(sampler2D s, float a)
{
    float x = a + (1.2 + s);

    ...
}

should only generate a single error.  Without the error_emitted flag for
the first error, "a + ..." would also generate an error.

However, a bunch of cases in _mesa_ast_array_index_to_hir that were
setting error_emitted would mask legitimate errors.  For example,

    vec4 a[7];
    float b = a[3.14];

should generate two error (float index and type mismatch in assignment).
The uses of error_emitted would cause only the first to be emitted.

This patch removes most of the places in _mesa_ast_array_index_to_hir
that would set the error_emitted flag.

11 years agoglsl: Add an optimization pass to flatten simple nested if blocks.

glsl: Add an optimization pass to flatten simple nested if blocks.

GLBenchmark 2.7's shaders contain conditional blocks like:

if (x) {
    if (y) {
        ...
    }
}

where the outer conditional's then clause contains exactly one statement
(the nested if) and there are no else clauses.  This can easily be
optimized into:

if (x && y) {
    ...
}

This saves a few instructions in GLBenchmark 2.7:

    total instructions in shared programs: 11833 -> 11649 (-1.55%)
    instructions in affected programs:     8234 -> 8050 (-2.23%)

It also helps CS:GO slightly (-0.05%/-0.22%).  More importantly,
however, it simplifies the control flow graph, which could enable other

i965: Remove fixed-function texture projection avoidance optimization.

This optimization attempts to avoid extra attribute interpolation
instructions for texture coordinates where the W-component is 1.0.

Unfortunately, it requires a lot of complexity: the brw_wm_input_sizes
state atom (all the brw_vs_constval.c code) needs to run on each draw.
It computes the input_size_masks array, then uses that to compute
proj_attrib_mask.  Differences in proj_attrib_mask can cause
state-dependent fragment shader recompiles.  We also often fail to guess
proj_attrib_mask for the fragment shader precompile, causing us to
needlessly compile it twice.

Furthermore, this optimization only applies to fixed-function programs;
it does not help modern GLSL-based programs at all.  Generally, older
fixed-function programs run fine on modern hardware anyway.

The optimization has existed in some form since the initial commit.  When
we rewrote the fragment shader backend, we dropped it for a while.  Eric
readded it in commit eb30820f268608cf451da32de69723036dddbc62 as part of
an attempt to cure a ~1% performance regression caused by converting the
fixed-function fragment shader generation code from Mesa IR to GLSL IR.
However, no performance data was included in the commit message, so it's
unclear whether or not it was successful.

Time has passed, so I decided to re-measure this.  Surprisingly,
Eric's OpenArena timedemo actually runs /faster/ after removing this and
the brw_wm_input_sizes atom.  On Ivybridge at 1024x768, I measured a
1.39532% +/- 0.91833% increase in FPS (n = 55).  On Ironlake, there was

gallivm: do per-pixel cube face selection (finally!!!)

This proved to be tricky, the problem is that after selection/mirroring
we cannot calculate reasonable derivatives (if not all pixels in a quad
end up on the same face the derivatives could get "randomly" exceedingly
large).
However, it is actually quite easy to simply calculate the derivatives
before selection/mirroring and then transform them similar to
the cube coordinates (they only need selection/projection, but not
mirroring as we're not interested in the sign bit, of course). While
there is a tiny bit more work to do (need to calculate derivs for 3
coords instead of 2, and additional selects) it also simplifies things
somewhat for the coord selection itself (as we save some broadcast aos
shuffles, and we don't need to calculate the average vector) - hence if
derivatives aren't needed this should actually be faster.
Also, this has the benefit that this will (trivially) work for explicit
derivatives too, which we completely ignored before that (will be in a
separate commit for better trackability).
Note that while the way for getting rho looks very different, it should
result in "nearly" the same values as before (the "nearly" is only because
before the code would choose the face based on an "average" vector and hence
the derivatives calculated according to this face, where now (for implicit
derivatives) the derivatives are projected on the face selected for the
first (top-left) pixel in a quad, so not necessarly the same face).
The transformation done might not quite be state-of-the-art, calculating
length(dx,dy) as max(dx,dy) certainly isn't neither but this stays the
same as before (that is I think a better transform would _somehow_ take
the "derivative major axis" into account so that derivative changes in
the major axis wouldn't get ignored).
Should solve some accuracy problems with cubemaps (can easily be seen with
the cubemap demo when switching wrapping/filtering), though we still don't
do seamless filtering to fix it completely (so not per-sample but per-pixel
is certainly better than per-quad and already sufficient for accurate
results with nearest tex filter).

As for performance, it seems to be a tiny bit faster too (maybe 3% or so
with cubemap demo). Which I'd have expected with nearest/nearest filtering
where this will be less instructions, but the difference seems to actually
be larger with linear/linear_mipmap_linear where it is slightly more
instructions, probably the code appears less serialized allowing better
scheduling (on a sandy bridge cpu). It actually seems to be now at least
as fast as the old path using a conditional when using 128bit vectors too
(that is probably more a result of testing with a newer cpu though), for now
that old path is still there but unused.
No piglit regressions.
