| * | SkSemaphore: use SYNC_POLICY_LIFO on Mach. |  mtklein | 2015-06-17 |
| | | | | | | | | | | | | | | | | Turns out _LIFO does work as we expected, keeping N < M threads active when we have M live threads but only N units of work to do at a time. Also as we expected _FIFO does round-robin through the threads. Performance doesn't seem to be affected, but let's do it anyway. If nothing else this makes profiles a little easier to read. I don't see POSIX or Windows equivalents. BUG=skia: Review URL: https://codereview.chromium.org/1192433006 | ||
| * | Add and use SkSemaphore | mtklein | 2015-06-17 |
| This allows a faster implementation of our SkTaskGroup thread pool. It also means we don't need SkCondVar (which, remember, isn't supported on XP.) Doing some testing with SampleApp, this really cuts down on the overhead from SkTaskGroup, e.g. 30% to 10%. BUG=skia: Review URL: https://codereview.chromium.org/1192573003 | |||
