45 * WMI event receiving - theory of operations
46 *
47 * When firmware about to report WMI event, it fills memory area
48 * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
49 * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
50 *
51 * @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the
52 * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
53 * and handles events within the @wmi_event_worker. Every event get detached
54 * from list, processed and deleted.
55 *
56 * Purpose for this mechanism is to release IRQ thread; otherwise,
57 * if WMI event handling involves another WMI command flow, this 2-nd flow
58 * won't be completed because of blocked IRQ thread.

62 * Addressing - theory of operations
63 *
64 * There are several buses present on the WIL6210 card.
65 * Same memory areas are visible at different address on
66 * the different busses. There are 3 main bus masters:
67 * - MAC CPU (ucode)
68 * - User CPU (firmware)
69 * - AHB (host)
70 *
71 * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
72 * AHB addresses starting from 0x880000
73 *
74 * Internally, firmware uses addresses that allow faster access but
75 * are invisible from the host. To read from these addresses, alternative
76 * AHB address must be used.
