This is the preferred location for bots which don't need to run on physical + hardware, ie. anything that doesn't require a GPU or a specific hardware configuration. Most of + our compile bots live here, along with some non-GPU test bots on Linux and Windows. We get + surprisingly stable performance numbers from GCE, despite very few guarantees about the physical + hardware. +* Chrome Golo. This is the preferred location for bots which require specific hardware or OS + configurations that are not supported by GCE. We have several Mac, Linux, and Windows bots in the + Golo. +* The Skolo (local Skia lab in Chapel Hill). Anything we can't get in GCE or the Golo lives + here. This includes a wider variety of GPUs and all Android, ChromeOS, iOS, and other devices. + +[go/skbl](https://goto.google.com/skbl) lists all Skia Swarming bots. + +Adding new jobs +--------------- + +See [Skia Automated Testing](automated_testing) for an overview of how jobs and tasks are executed +by the Skia Task Scheduler. + +If you would like to add jobs to build or test new configurations, please file a [New Bot +Request](https://bugs.chromium.org/p/skia/issues/entry?template=New+Bot+Request). + +If you know that the new jobs will need new hardware or you aren't sure which existing bots should +run the new jobs, assign to jcgregorio. Once the Infra team has allocated the hardware, we will +assign back to you to complete the process. + +Generally it's possible to copy an existing job and make changes to accomplish what you want. You +will need to add the new job to +[infra/bots/jobs.json](https://skia.googlesource.com/skia/+/master/infra/bots/jobs.json). In some +cases, you will need to make changes to recipes: + +* If there are new GN flags or compiler options: + [infra/bots/recipe_modules/flavor/gn_flavor.py](https://skia.googlesource.com/skia/+/master/infra/bots/recipe_modules/flavor/gn_flavor.py) +* If there are modifications to dm flags: + [infra/bots/recipes/test.py](https://skia.googlesource.com/skia/+/master/infra/bots/recipes/test.py) +* If there are modifications to nanobench flags: + [infra/bots/recipes/perf.py](https://skia.googlesource.com/skia/+/master/infra/bots/recipes/perf.py) + +If you need to do something more complicated, or if you are not sure how to add and configure the +new jobs, please ask for help from borenet, benjaminwagner, or mtklein. + +Debugging +--------- + +If you need a physical machine/device to debug an issue, the [current +Trooper](http://skia-tree-status.appspot.com/trooper) can loan one from the Skolo. For Internet +access, you can connect to GoogleGuest WiFi. + +If you need to make changes on a Skolo device, please check with an Infra team member. Most can be +flashed/imaged back to a clean state, but others can not. + +If a permanent change needs to be made on the machine (such as an OS or driver update), please [file +a bug](https://bugs.chromium.org/p/skia/issues/entry?template=Infrastructure+Bug) and assign to +jcgregorio for reassignment. + + +Maintenance Tasks +----------------- + +See the [Skolo maintenance +doc](https://docs.google.com/document/d/1zTR1YtrIFBo-fRWgbUgvJNVJ-s_4_sNjTrHIoX2vulo/edit). |
