* skpbench: add option for gpu timingGravatar csmartdalton2016-10-04
| | | | | | | | | Adds a gpu timing option with a GL implementation. BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2388433003 Review-Url: https://codereview.chromium.org/2388433003
* Move GPU fences into sk_gpu_testGravatar csmartdalton2016-10-04

* skpbench: use accumulative result as the defaultGravatar csmartdalton2016-09-29
| | | | | | | | | | | Uses accum instead of median for the first column in skpbench.cpp, and the default result for parseskpbench.py. The accum is empirically proving to be more repeatable than the median. BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2378383002 Review-Url: https://codereview.chromium.org/2378383002
* skpbench: use double buffering instead of tripleGravatar csmartdalton2016-09-28
| | | | | | | | | | | We have no need for our command stream to get more than a couple of frames deep. Any more and we only increase our chances of sporadic flushing and unreliable timings.

* skpbench: run for a fixed durationGravatar csmartdalton2016-09-28
| | | | | | | | | Runs for a fixed amount of time instead of a fixed amount of samples. BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2374093002 Review-Url: https://codereview.chromium.org/2374093002

* Add hardware monitoring to skpbenchGravatar csmartdalton2016-09-22
| | | | | | | | | | | | | | | Adds a Hardware class with hooks for entering and exiting "benchmarking" mode (e.g. locking clocks, etc.) as well as periodic polling of hardware to verify the environment is stable. Adds a partial implementation for generic Android hardware, but ultimately we will need to write specific classes tailored to each unique platform we need to test.

skpbench is a benchmarking suite for skps that aims to generate 100% repeatable results. The initial commit consists of three parts: skpbench A minimalist program whose sole purpose is to open an skp file, benchmark it on a single config, and exit. No tiling, looping, or other fanciness is used; it just draws the skp whole into a size- matched render target and syncs the GPU after each draw. Limiting the entire process to a single config/skp pair helps to keep the results repeatable. skpbench.py A wrapper to execute the skpbench binary with various configs and skps. It also monitors the output in order to filter out and re-run results with an unacceptable stddev. In the future this script will lock down and monitor clocks and temperatures. parseskpbench.py A utility for parsing skpbench output into a spreadsheet.
