20 ---help---
21 ISR registers on wil6210 chip may operate in either
22 COR (Clear-On-Read) or W1C (Write-1-to-Clear) mode.
23 For production code, use COR (say y); is default since
24 it saves extra target transaction;
25 For ISR debug, use W1C (say n); is allows to monitor ISR
26 registers with debugfs. If COR were used, ISR would
27 self-clear when accessed for debug purposes, it makes
28 such monitoring impossible.
29 Say y unless you debug interrupts

32 * When handling interrupt, one have to mask/unmask interrupts for the

25/**
26 * WMI event receiving - theory of operations
27 *
28 * When firmware about to report WMI event, it fills memory area
29 * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for
30 * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler.
31 *
32 * @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the
33 * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up
34 * and handles events within the @wmi_event_worker. Every event get detached
35 * from list, processed and deleted.
36 *
37 * Purpose for this mechanism is to release IRQ thread; otherwise,
38 * if WMI event handling involves another WMI command flow, this 2-nd flow
39 * won't be completed because of blocked IRQ thread.

43 * Addressing - theory of operations
44 *
45 * There are several buses present on the WIL6210 card.
46 * Same memory areas are visible at different address on
47 * the different busses. There are 3 main bus masters:
48 * - MAC CPU (ucode)
49 * - User CPU (firmware)
50 * - AHB (host)
51 *
52 * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing
53 * AHB addresses starting from 0x880000
54 *
55 * Internally, firmware uses addresses that allows faster access but
56 * are invisible from the host. To read from these addresses, alternative
57 * AHB address must be used.
58 *
59 * Memory mapping
