* Implement Porter Duff XP with a blend tableGravatar cdalton2015-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removes the runtime logic used by PorterDuffXferProcessor to decide blend coeffs and shader outputs, and instead uses a compile-time constant table of pre-selected blend formulas. Separates out the dst read fallback into its own XP. Introduces a new blend strategy for srcCoeff=0 that can apply coverage with a reverse subtract blend equation instead of dual source blending. Adds new macros in GrBlend.h to analyze blend formulas both runtime. Removes kSetCoverageDrawing_OptFlag and GrSimplifyBlend as they are no longer used. Adds a GM that verifies all xfermodes, including arithmetic, with the color/coverage invariants used by Porter Duff. Adds a unit test that verifies each Porter Duff formula with every color/coverage invariant. Major changes: * Uses a reverse subtract blend equation for coverage when srcCoeff=0 (clear, dst-out [Sa=1], dst-in, modulate). Platforms that don't support dual source blending no longer require a dst copy for dst-in and modulate. * Sets BlendInfo::fWriteColor to false when the blend does not modify the dst. GrGLGpu will now use glColorMask instead of blending for these modes (dst, dst-in [Sa=1], modulate ignored for [Sc=1]). * Converts all SA blend coeffs to One for opaque inputs, and ISA to Zero if there is also no coverage. (We keep ISA around when there is coverage because we use it to tweak alpha for coverage.) * Abandons solid white optimizations for the sake of simplicity (screen was the only mode that previous had solid white opts). Minor differences: * Inconsequential differences in opt flags (e.g. we now return kCanTweakAlphaForCoverage_OptFlag even when there is no coverage). * Src coeffs when the shader outputs 0. * IS2C vs IS2A when the secondary output is scalar.

* Move SkGpuDevice::internalDrawPath to GrBlurUtils::drawPathWithMaskFilterGravatar robertphillips2015-05-27
| | | | | | | | | | | This CL is ugly but it: removes the stored SkGpuDevice back pointer from GrTextContext (at the cost of passing more parameters) moves SkGpuDevice::internalDrawPath to GrDrawContext::drawPathFull Unfortunately, the GrTextContext-derived classes still need the SkGpuDevice for filterTextFlags calls but I will try removing that in a separate CL.

* Split drawing functionality out of GrContext and into new GrDrawContextGravatar robertphillips2015-05-26
| | | | | | | | This is mainly a mechanical CL. There were some fiddly bits in GrContext.cpp where it no longer had access to the GrDrawTarget (and had to use the new GrDrawContext). I've converted GrAARectRenderer & GrOvalRenderer into static classes so I could stop allocating them. Review URL: https://codereview.chromium.org/1151283004

* Make GrResourceCache perf less sensitive to key length changeGravatar kkinnunen2015-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make GrResourceCache performance less sensitive to key length change. The memcmp in GrResourceKey is called when SkTDynamicHash jumps the slots to find the hash by a index. Avoid most of the memcmps by comparing the hash first. This is important because small changes in key data length can cause big performance regressions. The theory is that key length change causes different hash values. These hash values might trigger memcmps that originally weren't there, causing the regression. Adds few specialized benches to grresourcecache_add to test different key lengths. The tests are run only on release, because on debug the SkTDynamicHash validation takes too long, and adding many such delays to development test runs would be unproductive. On release the tests are quite fast. Effect of this patch to the added tests on amd64: grresourcecache_find_10 738us -> 768us 1.04x grresourcecache_find_2 472us -> 476us 1.01x grresourcecache_find_25 841us -> 845us 1x grresourcecache_find_4 565us -> 531us 0.94x grresourcecache_find_54 1.18ms -> 1.1ms 0.93x grresourcecache_find_5 834us -> 749us 0.9x grresourcecache_find_3 620us -> 542us 0.87x grresourcecache_add_25 2.74ms -> 2.24ms 0.82x grresourcecache_add_56 3.23ms -> 2.56ms 0.79x grresourcecache_add_54 3.34ms -> 2.62ms 0.78x grresourcecache_add_5 2.68ms -> 2.1ms 0.78x grresourcecache_add_10 2.7ms -> 2.11ms 0.78x grresourcecache_add_2 1.85ms -> 1.41ms 0.76x grresourcecache_add 1.84ms -> 1.4ms 0.76x grresourcecache_add_4 1.99ms -> 1.49ms 0.75x grresourcecache_add_3 2.11ms -> 1.55ms 0.73x grresourcecache_add_55 39ms -> 13.9ms 0.36x grresourcecache_find_55 23.2ms -> 6.21ms 0.27x On arm64 the results are similar. On arm_v7_neon, the results lack the discontinuity at 55: grresourcecache_add 4.06ms -> 4.26ms 1.05x grresourcecache_add_2 4.05ms -> 4.23ms 1.05x grresourcecache_find 1.28ms -> 1.3ms 1.02x grresourcecache_find_56 3.35ms -> 3.32ms 0.99x grresourcecache_find_2 1.31ms -> 1.29ms 0.99x grresourcecache_find_54 3.28ms -> 3.24ms 0.99x grresourcecache_add_5 6.38ms -> 6.26ms 0.98x grresourcecache_add_55 8.44ms -> 8.24ms 0.98x grresourcecache_add_25 7.03ms -> 6.86ms 0.98x grresourcecache_find_25 2.7ms -> 2.59ms 0.96x grresourcecache_find_4 1.45ms -> 1.38ms 0.95x grresourcecache_find_10 2.52ms -> 2.39ms 0.95x grresourcecache_find_55 3.54ms -> 3.33ms 0.94x grresourcecache_find_5 2.5ms -> 2.32ms 0.93x grresourcecache_find_3 1.57ms -> 1.43ms 0.91x The extremely slow case, 55, is postulated to be due to the index jump collisions running the memcmp. This is not visible on arm_v7_neon probably due to hash function producing different results for 32 bit architectures. This change is needed for extending path cache key in Gr NV_path_rendering codepath. Extending is needed in order to add dashed paths to the path cache.
