| 36 | * WMI event receiving - theory of operations |
| 37 | * |
| 38 | * When firmware about to report WMI event, it fills memory area |
| 39 | * in the mailbox and raises misc. IRQ. Thread interrupt handler invoked for |
| 40 | * the misc IRQ, function @wmi_recv_cmd called by thread IRQ handler. |
| 41 | * |
| 42 | * @wmi_recv_cmd reads event, allocates memory chunk and attaches it to the |
| 43 | * event list @wil->pending_wmi_ev. Then, work queue @wil->wmi_wq wakes up |
| 44 | * and handles events within the @wmi_event_worker. Every event get detached |
| 45 | * from list, processed and deleted. |
| 46 | * |
| 47 | * Purpose for this mechanism is to release IRQ thread; otherwise, |
| 48 | * if WMI event handling involves another WMI command flow, this 2-nd flow |
| 49 | * won't be completed because of blocked IRQ thread. |

| 55 | * There are several buses present on the WIL6210 card. |
| 56 | * Same memory areas are visible at different address on |
| 57 | * the different busses. There are 3 main bus masters: |
| 58 | * - MAC CPU (ucode) |
| 59 | * - User CPU (firmware) |
| 60 | * - AHB (host) |
| 61 | * |
| 62 | * On the PCI bus, there is one BAR (BAR0) of 2Mb size, exposing |
| 63 | * AHB addresses starting from 0x880000 |
| 64 | * |
| 65 | * Internally, firmware uses addresses that allows faster access but |
| 66 | * are invisible from the host. To read from these addresses, alternative |
| 67 | * AHB address must be used. |
