of the hardware spec.  The documentation for most control flow
instructions mentions among other restrictions:

 "Instruction compression is not allowed."

This however doesn't have any implications on 16 wide not being
supported, because none of the control flow instructions have
multi-register operands (control flow instructions are not compressed
on more recent hardware either, except maybe SNB's IF with inline
compare).  In fact Gen4-5 had 16-wide control flow masks and stacks,
and the spec mentions in several places that control flow instructions
push and pop 16 channels worth of data -- Otherwise there doesn't seem
to be any indication that it shouldn't work.

From the hardware docs for the DO instruction:

 "Execution size is ignored for this instruction."

My observation on ILK hardware contradicts the spec though, channels
over the execution size of a DO instruction won't enter the loop, and
channels over the execution size of a WHILE instruction will exit the
loop after the first iteration -- The latter is consistent with the
spec though, there's no claim about the execution size being ignored
for the WHILE instruction so it's not completely unexpected that it
has an influence on the evaluation of EMask.

The execute_size argument of brw_DO() shouldn't have any effect on
Gen6 and newer hardware.  On Gen4-5 WHILE instructions inherit the
execution size from the matching DO, so this patch should fix them

i965/fs: Don't disable SIMD16 when using the pixel interpolator

There was a comment saying that in SIMD16 mode the pixel interpolator
returns coords interleaved 8 channels at a time and that this requires
extra work to support. However, this interleaved format is exactly
what the PLN instruction requires so I don't think anything needs to
be done to support it apart from removing the line to disable it and
to ensure that the message lengths for the send message are correct.

I am more convinced that this is correct because as it says in the
comment this interleaved output is identical to what is given in the
thread payload. The code generated to apply the plane equation to
these coordinates is identical on SIMD16 and SIMD8 except that the
dispatch width is larger which implies no special unmangling is
needed.

Perhaps the confusion stems from the fact that the description of the
PLN instruction in the IVB PRM seems to imply that the src1 inputs are
not interleaved so it wouldn't work. However, in the HSW and BDW PRMs,
the pseudo-code is different and looks like it expects the interleaved
format. Mesa doesn't seem to generate different code on IVB to
uninterleave the payload registers and everything is working so I can
only assume that the PRM is wrong.

I tested the interpolateAt tests on HSW and did a full Piglit run on
IVB on there were no regressions.

which point the instr's bb is updated to the new bb. Since that bb
doesn't have a joinAt set (despite containing one), when splitting after
the instr, there is nothing to copy over. Since the joinat will be in
the "split" bb irrespective of whether we're splitting before or after

9 years agogallivm: add fp64 support. (v2.1)
Dave Airlie [Sat, 27 Jun 2015 04:21:54 +0000 (14:21 +1000)]
gallivm: add fp64 support. (v2.1)

This adds support for ARB_gpu_shader_fp64 and ARB_vertex_attrib_64bit to
llvmpipe.

Two things that don't mix well are SoA and doubles, see
emit_fetch_double, and emit_store_double_chan in this.

I've also had to split emit_data.chan, to add src_chan,
which can be different for doubles.

It handles indirect double fetches from temps, inputs, constants
and immediates. It doesn't handle double stores to indirects,
however it appears the mesa/st doesn't currently emit these,
it always does UARL/MOV combos, which will work fine.

tested with piglit, no regressions, all the fp64 tests seem to pass.

v2:
switch to using shuffles for fetch/store (Roland)
assert on indirect double stores - mesa/st never emits these (it uses MOV)
fix indirect temp/input/constant/immediates (Roland)
typos/formatting fixes (Roland)

v2.1:
cleanup some long lines, emit_store_double_chan cleanups.

i965/fs: Remove the width field from fs_reg

As of now, the width field is no longer used for anything.  The width field
"seemed like a good idea at the time" but is actually entirely redundant
with the instruction's execution size.  Initially, it gave us the ability
to easily set the instructions execution size based entirely on register
widths.  With the builder, we can easiliy set the sizes explicitly and the
width field doesn't have as much purpose.  At this point, it's just
redundant information that can get out of sync so it really needs to go.
