* Move shader register setup to SkRasterPipelineBlitter.Gravatar Mike Klein2017-01-23
| | | | | | | | | | | | | | | | | | | | | We've been seeding the initial values of our registers to x+0.5,y+0.5, 1,0, 0,0,0,0 (useful values for shaders to start with) in all pipelines. This CL changes that to do so only when blitting, and only when we have a shader. The nicest part of this change is that SkRasterPipeline itself no longer needs to have a concept of y, or what x means. It just marches x through [x,x+n), and the blitter handles y and layers the meaning of "dst x coordinate" onto x. This ought to make SkSplicer a little easier to work with too. dm --src gm --config f16 srgb 565 all draws the same.

* SkSplicerGravatar Mike Klein2017-01-09
| | | | | | | | | | | | | | | | | | | | I think I may have cracked the compile-ahead-of-time-splice-at-runtime nut. This compiles stages ahead of time using clang, then splices them together at runtime. This means the stages can be written in simple C++, with some mild restrictions. This performs identically to our Xbyak experiment, and already supports more stages. As written this stands alone from SkRasterPipeline_opts.h, but I'm fairly confident that the bulk (the STAGE implementations) can ultimately be shared. As of PS 25 or so, this also supports all the stages used by bench/SkRasterPipelineBench.cpp: SkRasterPipeline_… 400 …f16_compile 1x …f16_run 1.38x …srgb_compile 1.89x …srgb_run 2.21x That is, ~30% faster than baseline for f16, ~15% faster for sRGB.

* clamp to premul when reading premul sRGBGravatar Mike Klein2016-12-13
| | | | | | | | | | | | | | | It's pretty easy to start with sound premultiplied linear floats, pack those to sRGB encoded bytes, then read them back to linear floats and find them not quite premultiplied, with a color channel just a smidge greater than the alpha channel. This can happen basically any time we have different transfer functions for alpha and colors... sRGB being the only one we draw into. This is an annoying problem with no known good solution. So apply the clamp hammer. These new calls on SkRasterPipeline should make it impossible to get wrong.

This is easy to tweak into something like (x+0.5, y+0.5, 1) in (dr,dg,db) once this lands. Mostly I just want to get all the uninteresting boilerplate out of the way first.

| | | | | | | | | | | | | | | | | | | | | | Bench runtime changes: sRGB: 7194 -> 3735 = 1.93x faster F16: 6531 -> 2559 = 2.55x faster Instead of building 4x and 1-3x pipelines and then maybe 8x and 1-7x, instead build either the short ones or the long ones, but not both. If we just take care to use a compatible run_pipeline(), there's some cross-module type disagreement but everything works out in the end. Oddly, a few places that looked like they'd be faster using SkNx_fma() or Sk4f_round()/Sk8f_round() are actually faster the long way, e.g. multiply, add 0.5, truncate. Curious! In all the other places you see here that I've used SkNx_fma(), it's been a significant speedup. This folds in a couple refactors and cleanups that I've been meaning to do. Hope you don't mind... if find the new code considerably easier to read than the old code.

* Add an enum layer of indirection for stock raster pipeline stages.Gravatar Mike Klein2016-09-29
| | | | | | | | | | | | | | | | | | This is handy now, and becomes necessary with fancier backends: - most code can't speak the type of AVX pipeline stages, so indirection's definitely needed there; - if the pipleine is entirely composed of stock stages, these enum values become an abstract recipe that can be JITted.

* Rearrange SkRasterPipeline scanline tail handling.Gravatar Mike Klein2016-09-28
| | | | | | | | | | | | | | | | | | | We used to step at a 4-pixel stride as long as possible, then run up to 3 times, one pixel at a time. Now replace those 1-at-a-time runs with a single tail stamp if there are 1-3 remaining pixels. This style is simply more efficient: e.g. we'll blend and lerp once for 3 pixels instead of 3 times. This should make short blits significantly more efficient. It's also more future-oriented... AVX+ on Intel and SVE on ARM support masked loads and stores, so we can do the entire tail in one direct step. This also makes it possible to re-arrange the code a bit to encapsulate each stage better. I think generally this code reads more clearly than the old code, but YMMV. I've arranged things so you write one function, but it's compiled into two specializations, one for tail=0 (Body) and one for tail>0 (Tail). It's pretty tidy. For now I've just burned a register to pass around tail. It's 2 bits now, maybe soon 3 with AVX, and capped at 4 for even the craziest new toys, so there are plenty of places we can pack it if we want to get clever.

* SkRasterPipeline: simplify impl and remove need to rewire stagesGravatar mtklein2016-07-13
| | | | | | | | | | | This builds the stages correctly wired from the get-go. With a little clever setup, we can also design around the previous error cases like having no stages or pipelines that call st->next() off the end.
