41 * WMI event receiving - theory of operations
42 *
43 * When firmware about to report WMI event, it fills memory area
44 * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
45 * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
46 *
47 * @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the
48 * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
49 * and handles events within the @wmi_event_worker. Every event get detached
50 * from list, processed and deleted.
51 *
52 * Purpose for this mechanism is to release IRQ thread; otherwise,
53 * if WMI event handling involves another WMI command flow, this 2-nd flow
54 * won't be completed because of blocked IRQ thread.

57/**
58 * Addressing - theory of operations
59 *
60 * There are several buses present on the WIL6210 card.
61 * Same memory areas are visible at different address on
62 * the different busses. There are 3 main bus masters:
63 * - MAC CPU (ucode)
64 * - User CPU (firmware)
65 * - AHB (host)
66 *
67 * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
68 * AHB addresses starting from 0x880000
69 *
70 * Internally, firmware uses addresses that allows faster access but
71 * are invisible from the host. To read from these addresses, alternative
72 * AHB address must be used.
73 *
74 * Memory mapping
75 * Linker address PCI/Host address
76 * 0x880000 .. 0xa80000 2Mb BAR0
77 * 0x800000 .. 0x807000 0x900000 .. 0x907000 28k DCCM
