| | | | | | | | | | | | | | | | | | | | | | It looks like we can specialize hot image shaders into their own single stages for a good speedup on both x86 and ARM. I've started here with bilerp_clamp_8888, and will follow up with bgra and 565, and lowp versions of those, and probably also the same for nearest neighbors. All pixels are identical in GMs. This time, rewrite the loop over sample points to be a little friendlier to 32-bit x86 code generation. The previous version created an object file indirection feature build_stages.py can't handle.

* Add cap on intel to avoid calling abs and floor on the same line in aGravatar Greg Daniel2017-12-02
| | | | | | | | | | | | | | | | | | | | shader. This fixes a bug on some intel devices where we are failing in the ProcessorOptimizationTest. I've tried other "no op" type things between the floor call and abs which also fixed the issue, as well as adding explicit checks to see if we are less than -1 or greater than 1 where the clamp is. Thus the clamp itself should be a no op and shouldn't secretly be fixing the problem outside of forcing the floor and abs lines to be separate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) reformulate the gradient data as a series of interpolation intervals, defined as tuples of (color_scale, color_bias) such that color(t) = t * color_scale + color_bias (this allows us to skip the relative_t computation and simply feed tiled_t into a fast MAD) 2) then, the existing specializations can be generalized as a) select an interpolation interval (possibly based on a threshold) b) compute the interpolated color using the method in #1 3) simplify the hard-edge cases by using clamp intervals (color_scale == 0) and relaxing the clamping step (allowing tiled_t < 0 or tiled_t > 1, in order to hit the clamping intervals during the selection step) The existing specializations are converted as follows: * kTwo_ColorType -> single interpolation interval, normal clamping * kThree_ColorType -> two interpolation intervals, normal clamping, threshold == pos[1] * kSingleHardStop_ColorType -> two interpolation intervals, normal clamping, threshold == pos[1/2] * kHardStopLeftEdged_ColorType -> two interpolation intervals, clamping (-inf, 1], threshold == 0 * kHardStopRightEdged_ColorType -> two interpolation intervals, clamping [0, +inf), threshold == 1 This reduces the SkSL overhead in a couple of ways: * the clamp stage is sometimes reduced to min/max vs. full clamp() * the color interpolation stage is just a MAD vs. full mix() Change-Id: I65be84d131d56136ec5e946c2b3dba149a4473cf Reviewed-on: https://skia-review.googlesource.com/68218 Reviewed-by: Brian Salomon <bsalomon@google.com> Commit-Queue: Florin Malita <fmalita@chromium.org>

* Detect explicit uniform gradient positionsGravatar Florin Malita2017-11-04
| | | | | | | | | | | | | | | | | | When the color stop positions are uniform, the client is allowed to not specify them (implicit positions, signaled by a null |pos| pointer). This enables some internal optiomizations and yields improved rasterization times. But if the client does pass explicit uniform positions, we currently treat them as general/non-uniform. Detect explicit uniform color stop positions at construction time, and drop them - to ensure optimal treatment downstream.

* Add support for transfer functions to GrColorSpaceXformGravatar Brian Osman2017-10-31
| | | | | | | | | | | | | | | | | | | With this change, untagged sources (eg N32) are treated as sRGB data, which causes a huge number of GMs to render more correctly in GPU sRGB/F16/etc... configs. Also, because the sources are treated as having a color space, we actually do gamut conversion for wide or narrow gamut outputs. This change also applies the transfer function math to individual colors in the case of gradient stops and color shaders. (The CPU backend doesn't do this yet, but I think we've decided there's no reason not to support it).
