Kevin Lubick de2f1dfebd Turn up Nexus10 CPU frequencies
The previous list was created from scaling_min_freq and scaling_max_freq
instead of cpuinfo_min_freq and cpuinfo_max_freq which are the actual mins
and maxes, not the current (transient) settings of the governor.

Before:
Test-Release: 61 minutes
Perf-Debug: 41 minutes

After:
Test-Release: 32 minutes
Perf-Debug: 16 minutes

Skia Infrastructure

This directory contains infrastructure elements.

Tasks and Jobs

Files in this directory define a DAG of tasks which run at every Skia commit. A task is a small, self-contained unit which runs via Swarming on a machine in the pool. Tasks may be chained together, eg. one task to compile test binaries and another to actually run them.

Jobs are collections of related tasks which help define sub-sections of the DAG, for example, to be used as try jobs. Each job is defined as an entry point into the DAG.

The tasks.json file in this directory is the master list of tasks and jobs for the repo. Note that tasks.json is NEVER edited by hand but generated via gen_task.go and the input files enumerated below. The Task Scheduler reads the tasks.json file at each commit to determine which jobs to run. For convenience, gen_tasks.go is provided to generate tasks.json and also to test it for correct syntax and detecting cycles and orphaned tasks. Always edit gen_tasks.go or one of the following input JSON files, rather than tasks.json itself:

  • android_map.json - Maps human-friendly names of Android devices to their device codename and desired OS version. Edit this file when adding a new type of Android device or updating the desired OS version.
  • cfg.json - Basic configuration information for gen_tasks.go.
  • gpu_map.json - Maps human-friendly names of GPUs to an appropriate Swarming dimension, typically the PCI ID of the GPU. Edit this file when adding a new GPU.
  • jobs.json - The master list of all jobs to run. Edit this to add or remove bots.

Whenever gen_tasks.go, any of the above JSON files, or assets are changed, you need to run gen_tasks.go to regenerate tasks.json:

$ go run infra/bots/gen_tasks.go

Or:

$ cd infra/bots; make train

There is also a test mode which performs sanity-checks and verifies that tasks.json is unchanged:

$ go run infra/bots/gen_tasks.go --test

Or:

$ cd infra/bots; make test

Recipes

Recipes are the framework used by Skia's infrastructure to perform work inside of Swarming tasks. The main elements are:

  • recipes.py - Used for running and testing recipes.
  • recipes - These are the entry points for each type of task, eg. compiling or running tests.
  • recipe_modules - Shared modules which are used by recipes.
  • .recipe_deps - Recipes and modules may depend on modules from other repos. The recipes.py script automatically syncs those dependencies in this directory.

Isolate Files

These files determine which parts of the repository are transferred to the bot when a Swarming task is triggered. The Isolate tool hashes each file and will upload any new/changed files. Bots maintain a cache so that they can efficiently download only the files they don't have.

Assets

Artifacts used by the infrastructure are versioned here, along with scripts for recreating/uploading/downloading them. See the README in that directory for more information. Any time an asset used by the bots changes, you need to re-run gen_tasks.go.

Tools

Assorted other infrastructure-related tools, eg. isolate and CIPD binaries.
