* DM: make GPU tasks multithreaded again. Big refactor.Gravatar commit-bot@chromium.org2014-02-28
| | | | | | | | | | | | | | | | | | | | | | The main meat of things is in SkThreadPool. We can now give SkThreadPool a type for each thread to create and destroy on its local stack. It's TLS without going through SkTLS. I've split the DM tasks into CpuTasks that run on threads with no TLS, and GpuTasks that run on threads with a thread local GrContextFactory. The old CpuTask and GpuTask have been renamed to CpuGMTask and GpuGMTask. Upshot: default run of out/Debug/dm goes from ~45 seconds to ~20 seconds.

* DM: also run benches once.Gravatar commit-bot@chromium.org2014-02-26
| | | | | | | | | | | | | | | | | | Also: - make GrMemoryPoolBenches threadsafe - some tweaks to various DM code - rename GM::shortName() to getName() to match benches and tests On my desktop, (289 GMs, 617 benches) x 4 configs, 227 tests takes 46s in Debug, 14s in Release. (Still minutes faster than running tests && bench && gm.) GPU singlethreading is definitely the limiting factor again; going to reexamine whether that's helpful to thread it again.

* Add support for reading a directory of images with --expectations (-r).Gravatar commit-bot@chromium.org2013-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DM writes out its images in a hierarchy that's a little different than GM, so this can't read GM's output. But it can read its own, written with -w. Example usage: $ out/Release/dm -w /tmp/baseline $ out/Release/dm -r /tmp/baseline -w /tmp/new (and optionally) $ mkdir /tmp/diff; out/Release/skdiff /tmp/baseline /tmp/new /tmp/diff GM's IndividualImageExpectationsSource and Expectations are a little too eager about decoding and hashing the expected images, so I took the opportunity to add DM::Expectations that mostly replaces skiagm::ExpectationsSource and skiagm::Expectations in DM. It mainly exists to move the image decoding and comparison off the main thread, which would otherwise be a major speed bottleneck. I tried to use skiagm code where possible. One notable place where I differed is in this new feature. When -r is a directory of images, DM does no hashing. It considerably faster to read the expected file into an SkBitmap and do a byte-for-byte comparison than to hash the two bitmaps and check those. The example usage above isn't quite working 100% yet. Expectations on some GMs fail, even with no binary change. I haven't pinned down whether this is due to - a bug in DM - flaky GMs - unthreadsafe GMs - flaky image decoding - unthreadsafe image decoding - something else but I intend to. Leon, Derek and I have suspected PNG decoding isn't threadsafe, but are as yet unable to prove it. I also seem to be able to cause malloc to fail on my laptop if I run too many configs at once, though I never seem to be using more than ~1G of RAM. Will track that down too.

* dm is like gm, but faster and with fewer features.Gravatar mtklein@google.com2013-10-16
This is sort of the near-minimal proof-of-concept skeleton. - It can run existing GMs. - It supports most configs (just not PDF). - --replay is the only "fancy" feature it currently supports Hopefully you will be disturbed by its speed.
