kriswright e326c6a800 Bug 1748378 - Create a way to deprioritize threadpools. r=nika ... This will be used to deprioritize whole thread pools. The concept works as such: - Set a thread pool's priority at any time - Each thread will ensure their priority mirrors the parent pool's priority when it is finished processing events. I chose to have threads only set themselves to the background when they finish processing events because an event dispatched at an expected priority should be completed at said priority. This ensures that any event dispatch that may expect normal priority (i.e. not operating in the background) has a chance to run at the established priority. This patch enrolls the background IO to low priority on its creation. It also includes the MacOS implementation of the thread priorities, which utilizes mac's QoS service. According to MacOS's QoS structure, main threads operate at `user-interactive` and offthread work is done at a `default` state, meaning that the OS decides how to set the thread's priority somewhere between `utility` and `user-interactive`. When a thread is put in the background, it must be manually raised back to the expected priority, which means most threads must set themselves to `default` again and the main thread must set itself to `user-interactive`. I demonstrated this in the `nsThread` implementation by checking for the main thread and if this task is running on the main thread somehow, then we use the correct setting. Rather than having the thread pools dispatch their own deprioritization tasks, I've decided to make this the job of the nsThread. In following bugs we will put entire processes' nsThreads in the background, which will require more use of the new nsThread codepaths. This behavior is currently restricted to nightly only. On platforms with no implementation, nothing will change. Differential Revision: https://phabricator.services.mozilla.com/D146534		2023-02-03 16:36:47 +00:00
