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. | |
