* WMI event receiving - theory of operations
|
|
*
|
|
* When firmware about to report WMI event, it fills memory area
|
|
* in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
|
|
* the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
|
|
*
|
|
* @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the
|
|
* event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
|
|
* and handles events within the @wmi_event_worker. Every event get detached
|
|
* from list, processed and deleted.
|
|
*
|
|
* Purpose for this mechanism is to release IRQ thread; otherwise,
|
|
* if WMI event handling involves another WMI command flow, this 2-nd flow
|
|
* won't be completed because of blocked IRQ thread.
