8 years agofreedreno/ir3: convert scheduler back to recursive algo
Rob Clark [Mon, 30 Nov 2015 20:52:26 +0000 (15:52 -0500)]
freedreno/ir3: convert scheduler back to recursive algo

I've played with a few different approaches to tweak instruction
priority according to how much they increase/decrease register pressure,
etc.  But nothing seems to change the fact that compared to original
(pre-multiple-block-support) scheduler, in some edge cases we are
generating shaders w/ 5-6x higher register usage.

The problem is that the priority queue approach completely looses the
dependency between instructions, and ends up scheduling all paths at the
same time.

Original reason for switching was that recursive approach relied on
starting from the shader outputs array.  But we can achieve more or less
the same thing by starting from the depth-sorted list.

shader-db results:

total instructions in shared programs:          113350 -> 105183 (-7.21%)
total dwords in shared programs:                219328 -> 211168 (-3.72%)
total full registers used in shared programs:   7911 -> 7383 (-6.67%)
total half registers used in shader programs:   109 -> 109 (0.00%)
total const registers used in shared programs:  21294 -> 21294 (0.00%)

                 half       full      const      instr     dwords
    helped           0         322           0         711         215
      hurt           0         163           0          38           4

The shaders hurt tend to gain a register or two.  While there are also a
lot of helped shaders that only loose a register or two, the more
complex ones tend to loose significanly more registers used.  In some
more extreme cases, like glsl-fs-convolution-1.shader_test it is more
like 7 vs 34 registers!

if there was a corresponding fs input, otherwise the layer/vp index would get

d3d10 actually requires using provoking (first) vertex. GL is happy with

Up to now we actually used vertex 0 for viewport index, and vertex 1 for
layer (for tris), which really didn't make sense (probably a typo). Also,$
since we reorder vertices of clockwise triangle, that actually meant we used
a different vertex depending if the traingle was cw or ccw (still ok by gl).
However, it should be consistent with what draw (clip) does, and using
provoking vertex seems like the sensible choice (draw clip will be fixed
next as it is totally broken there).
While here, also use the correct viewport always even when not needed
in setup (we pass it down to jit fragment shader it might be needed there

  GL_ACTIVE_PROGRAM -- in our hash table, GL_ACTIVE_PROGRAM_EXT points at
  the GLES2 enum's value (aka GL_CURRENT_PROGRAM).  By not blacklisting
