* add SkStubHeifDecoderAPI.hGravatar Mike Klein2017-10-20
| | | | | | | | | | | | | | | This should let us build SkHeifCodec even without libheif. I didn't look at libheif itself, so this stub may disagree a bit with the actual interface... just flailed around until it compiled and linked. This turns on the stub in most of our internal builds.

* GPU-CTS ProgramGravatar Hal Canary2017-10-17
| | | | | | | | | | | | | | | | | | | | Add new application, called GPU-CTS (GPU Compatibility Test Suite), which executes skia gms against OpenGL and Vulkan backends. Makes use of googletest library for consistancy with Android CTS programs. Add googletest to DEPS gm_knowledge.h header as a stub for future work on validating gm output. gm_runner can be re-used in other programs. Talks to Skia and GM with a simple API. gpuctx executable wraps gm_runner and googletest together.

| | | | | | | | | | | | | Fuchsia also builds Skia for host and wants to set various gn variables (e.g., skia_enable_flutter_defines) when is_linux is true. Rather than teach Skia about all these permutations, this CL adds a skia_settings variable that can be used by clients to customize Skia's configuration.

* grand unifried lowp stagesGravatar Mike Klein2017-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | I have text_16_AA_FF -> 8888 (forcing RP) faster than head now on my laptop. I'm feeling confident that we can make this perform well. After looking at performance a bit more today, it looks like everything is within what I'd consider comparable in performance, especially on ARM. On x86-64 it looks like big bulk blits get a little slower and small mask blits get a little faster. Quality looks good, and maybe improved for 565. There are fewer platform-specific differences now in _lowp, and I think they're few enough now that we could even consider completing the unification by folding the 8-bit and float code together. Rename "div255()" to "rebias()", slap on a few coats of paint... Guarded for Chrome with SK_JUMPER_LEGACY_LOWP.

* ok, add a bench sourceGravatar Mike Klein2017-08-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new source acts like other sources (GMs, SKPs) for benchmarks. It times multiple samples (controlled by samples=N, default 20), and each of those samples uses the same strategy as monobench, growing loops exponentially until it runs for at least 10ms. When done it prints the fastest and the two slowest samples. In practice the 100th percentile sample is very different from the next slowest due to caching, and the fastest is always interesting. Because these benchmarks run in whatever execution engine ok has selected, on non-Windows platforms you have some real control over the interaction between benchmarks. In its default "fork" mode each benchmark runs independently in its own process, so the 100th percentiles really stand out. The other modes "thread" and "serial" work as you'd expect too. Here's an example where you can see how the different interactions work: out/ok bench:samples=100 8888 filter:search=text_16_AA fork [text_16_AA_WT] 2.32µs @0 6.23µs @99 24.3ms @100 [text_16_AA_FF] 2.41µs @0 5.7µs @99 23.3ms @100 [text_16_AA_88] 2.55µs @0 5.6µs @99 24.8ms @100 [text_16_AA_BK] 1.97µs @0 5.44µs @99 23.2ms @100 out/ok bench:samples=100 8888 filter:search=text_16_AA thread [text_16_AA_FF] 2.45µs @0 23.5µs @99 24.8ms @100 [text_16_AA_WT] 2.52µs @0 17.8µs @99 24.7ms @100 [text_16_AA_88] 2.55µs @0 19.7µs @99 25.1ms @100 [text_16_AA_BK] 1.8µs @0 14.7µs @99 25.1ms @100 out/ok bench:samples=100 8888 filter:search=text_16_AA serial [text_16_AA_88] 2.35µs @0 3.53µs @99 16.7ms @100 [text_16_AA_FF] 2.09µs @0 2.73µs @99 2.91µs @100 [text_16_AA_BK] 1.75µs @0 2.46µs @99 2.65µs @100 [text_16_AA_WT] 2.1µs @0 3.16µs @99 3.17µs @100 In the first "fork" case all runs are independent and have roughly the same profile. "thread" looks similar except you can see them contending at the 99th percentile. In "serial", the first bench warms up the rest, so their 100th percentiles are all much faster.

* 8-bit hackingGravatar Mike Klein2017-08-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | I think we can replace a lot of legacy code with an SkRasterPipeline backend that works in 8-bit and stays interlaced. Think of this as a "lowerp" replacement for lowp. I'm having some trouble getting ARMv8 working. ARMv7 should be fine, but I want to turn it on separately from x86. I haven't looked at 32-bit x86 yet, but that's also on the todo list. Open questions to follow up on: - is it better to fold every multiply back down to 8-bit (as seen here), or to allow intermediates to accumulate in 16-bit and divide by 255 when done/needed? - is it better pass tightly packed 8-bit vectors between stages (as seen here), or to keep the 8-bit values unpacked in 16-bit lanes? - should we make V wider than 1 register? GMs look good. All diffs invisible and plausibly due to the 15->8 bit precision drop. A quick bench run showed this running in about 0.75x the time of the existing lowp backend.

| | | | | | | | | | | | | | This makes Engines (task execution strategies: serial, thread, fork) pluggable just like most of the rest of ok. It removes the thread and process limits, as I find myself rarely caring about what they are exactly. Instead of limiting to num-cores, we just allow any number of concurrent threads, and any number of concurrent child processes subject to OS limitations.

| | | | | | | | | | | | | | | | | | | | Not yet thread safe (so it forces threading off). Builds JSON on the fly, so overhead is certainly bad. Plan to fix all of that, but this at least "works". There is now one tracing flag: 'trace'. - 'debugf' installs the SkDebugf tracer. - 'atrace' installs the Android ATrace tracer. - Any other value is interpreted as a filename, and produces a JSON file for chrome://tracing. All three modes work in DM, nanobench, and Viewer.
