llvmpipe: fix issues with depth clamp

We only did depth clamp when the value was written from the fs.
This is very wrong both for d3d10 and GL, and only passed the
corresponding piglit test due to pure luck (it no longer does
with the enhanced test).
Also, interpolation clamped values to 1.0 always, which can legitimately
happen if depth clip is disabled, so fix that as well (untested).
There is one unresolved issue left, d3d10 always does depth clamping,
whereas GL does not (but does [0,1] clamp instead for fs depth outputs)
- this information isn't in any gallium state object, leave it as-is
for now (though it looks like llvmpipe misses the [0,1] clamp as well).
This (with the previous patch) fixes piglit depth-clamp-range test.

i965/vec4: Ignore swizzle of VGRF for use by var_range_end().

var_range_end(v, n) loops over the n components of variable number v and
finds the maximum value, giving the last use of any component of v.
Therefore it expects v to correspond to the variable associated with the
.x channel of the VGRF.

var_from_reg() however returns the variable for the first channel of the
VGRF, post-swizzle.

So, if the last register had a swizzle with y, z, or w in the swizzle
component, we would read out of bounds. For any other register, we would
read liveness information from the next register.

The fix is to convert the src_reg to a dst_reg in order to call the
dst_reg version of var_from_reg() that doesn't consider the swizzle.

i965/sched: Change the scheduling heuristics to favor early program termination.

This uses the unblocked time of the exit assigned to each available
node to attempt to unblock exit nodes as early as possible,
potentially reducing the runtime of the shader when an exit branch is
taken.  There is a natural trade-off between terminating the program
as early as possible and reducing the worst-case latency of the
program as a whole (since this will typically move exit-unblocking
nodes closer to its dependencies potentially causing additional stalls
of the execution pipeline), but in practice the bandwidth and ALU
cycle savings from terminating the program earlier tend to outweigh
the slight increase in worst-case program execution latency, so it
makes sense to prefer nodes likely to unblock an earlier exit
regardless of the latency benefits of other available nodes.

I haven't observed any benchmark regressions from this change after
testing on VLV, HSW, BDW, BSW and SKL.  The FPS of the GfxBench
Manhattan benchmark increases by 10%-20% and the FPS of Unigine Valley
improves by roughly 5% depending on the platform and settings.

The change to the register pressure-sensitive heuristic is rather
conservative and gives precedence to the existing heuristic in order
to avoid increasing register pressure and causing spill count and SIMD
width regressions in shader-db.  It may make sense to revisit this

disabled by the EU until the end of the program, regardless of whether
the discard condition is uniform across all channels of the SIMD8-16
thread.  OTOH ANY8H/ANY16H would cause the rest of the program to be
executed for *all* channels if only one of the channels hadn't taken
the discard branch, potentially increasing the bandwidth and ALU usage
of the program unnecessarily.

This change increases the FPS by over 3x of a simple micro-benchmark

Note that we could potentially be more aggressive and use the NORMAL
predicate to discard individual channels, but that would need to
happen post-scheduling because the scheduler currently doesn't care to
reorder HALT instructions with respect to other instructions, and the

8 years agomesa: Fix uf10_to_f32() scale factor in the E == 0 and M != 0 case.
Kenneth Graunke [Tue, 16 Aug 2016 05:26:42 +0000 (22:26 -0700)]
mesa: Fix uf10_to_f32() scale factor in the E == 0 and M != 0 case.

GL_EXT_packed_float, 2.1.B Unsigned 10-Bit Floating-Point Numbers:

        0.0,                      if E == 0 and M == 0,
        2^-14 * (M / 32),         if E == 0 and M != 0,
        2^(E-15) * (1 + M/32),    if 0 < E < 31,
        INF,                      if E == 31 and M == 0, or
        NaN,                      if E == 31 and M != 0,

In the second case (E == 0 and M != 0), we were multiplying the mantissa
by 2^-20, when we should have been multiplying by 2^-19 (which is
2^(-14 + -5), or 2^-14 * 2^-5, or 2^-14 / 32).

The previous section defines the formula for 11-bit numbers, which is:

        2^-14 * (M / 64),         if E == 0 and M != 0,

In other words, we had accidentally copy and pasted the 11-bit code
to the 10-bit case, and neglected to change the exponent.

Fixes dEQP-GLES3.functional.pbo.renderbuffer.r11f_g11f_b10f_triangles
when run with surface dimensions of 1536x1152 or 1920x1080.
