/**
* 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.
*/
/**
* Addressing - theory of operations
*
* There are several buses present on the WIL6210 card.
* Same memory areas are visible at different address on
* the different busses. There are 3 main bus masters:
* - MAC CPU (ucode)
* - User CPU (firmware)
* - AHB (host)
*
* On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
* AHB addresses starting from 0x880000
*
* Internally, firmware uses addresses that allow faster access but
* are invisible from the host. To read from these addresses, alternative
* AHB address must be used.
