35 * DOC: WMI event receiving - theory of operations
36 *
37 * When firmware about to report WMI event, it fills memory area
38 * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
39 * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
40 *
41 * @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the
42 * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
43 * and handles events within the @wmi_event_worker. Every event get detached
44 * from list, processed and deleted.
45 *
46 * Purpose for this mechanism is to release IRQ thread; otherwise,
47 * if WMI event handling involves another WMI command flow, this 2-nd flow
48 * won't be completed because of blocked IRQ thread.

52 * DOC: Addressing - theory of operations
53 *
54 * There are several buses present on the WIL6210 card.
55 * Same memory areas are visible at different address on
56 * the different busses. There are 3 main bus masters:
57 * - MAC CPU (ucode)
58 * - User CPU (firmware)
59 * - AHB (host)
60 *
61 * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
62 * AHB addresses starting from 0x880000
63 *
64 * Internally, firmware uses addresses that allow faster access but
65 * are invisible from the host. To read from these addresses, alternative
66 * AHB address must be used.

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.

70 *
71 * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
72 * AHB addresses starting from 0x880000

74 * Internally, firmware uses addresses that allow faster access but
