Hi, This series implements internal workqueues in the i915 driver in order to avoid using the system queue. We add one generic workqueue in the drm_i915_private structure, one specific for wake references and one in a self-test. This is based on Tetsuo's work[1] and is required to get rid of the flush_scheduled_work() usage. As discussed, we can either take Tetsuo's implementation first, which uses a module-global workqueue, and then my series on top of that, to change the implementation to per-device workqueues, or apply my series directly. And a third option would be to keep the workqueue as module-global. I'm fine with any of this options. It's up to the maintainers to decide which one to take. In v2: * Removed per-engine workqueue and wakeref-specific queue; * Renamed the workqueue name from "i915-wq" to "unordered_wq"; * Added comment about when the new workqueue should be used; * Changed wakeref structs to store i915 instead of rpm; In v3: * Fixed queue to destroy in the init error path; * Improved the new queue's description a bit; * Removed stray empty-line removal; In v4: * Fixed the queue used in __intel_wakeref_put_last(), we were accidentally using the ordered workqueue. Thanks, Tvrtko! Please review. [1] https://patchwork.freedesktop.org/series/114608/ Cheers, Luca.
