platform/surface: aggregator: Allow completion work-items to be executed in parallel 2023-05-30T09:20:16+00:00 Maximilian Luz luzmaximilian@gmail.com 2023-05-25T21:01:10+00:00 539e0a7f9105d19c00629c3f4da00330488e8c60 Currently, event completion work-items are restricted to be run strictly in non-parallel fashion by the respective workqueue. However, this has lead to some problems: In some instances, the event notifier function called inside this completion workqueue takes a non-negligible amount of time to execute. One such example is the battery event handling code (surface_battery.c), which can result in a full battery information refresh, involving further synchronous communication with the EC inside the event handler. This is made worse if the communication fails spuriously, generally incurring a multi-second timeout. Since the event completions are run strictly non-parallel, this blocks other events from being propagated to the respective subsystems. This becomes especially noticeable for keyboard and touchpad input, which also funnel their events through this system. Here, users have reported occasional multi-second "freezes". Note, however, that the event handling system was never intended to run purely sequentially. Instead, we have one work struct per EC/SAM subsystem, processing the event queue for that subsystem. These work structs were intended to run in parallel, allowing sequential processing of work items for each subsystem but parallel processing of work items across subsystems. The only restriction to this is the way the workqueue is created. Therefore, replace create_workqueue() with alloc_workqueue() and do not restrict the maximum number of parallel work items to be executed on that queue, resolving any cross-subsystem blockage.
