75 | * DOC: Driver system flows - drv component | |
76 | * | |
77 | * This component implements the system flows such as bus enumeration, bus | |
78 | * removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in | |
79 | * bus specific files (transport files). This is the code that is common among | |
80 | * different buses. | |
81 | * | |
82 | * This component is also in charge of managing the several implementations of | |
83 | * the wifi flows: it will allow to have several fw API implementation. These | |
84 | * different implementations will differ in the way they implement mac80211's | |
85 | * handlers too. | |
86 | ||
87 | * The init flow wrt to the drv component looks like this: | |
88 | * 1) The bus specific component is called from module_init | |
89 | * 2) The bus specific component registers the bus driver | |
90 | * 3) The bus driver calls the probe function | |
91 | * 4) The bus specific component configures the bus | |
92 | * 5) The bus specific component calls to the drv bus agnostic part | |
93 | * (iwl_drv_start) | |
1c8e11e1 EG |
94 | * 6) iwl_drv_start fetches the fw ASYNC, iwl_req_fw_callback |
95 | * 7) iwl_req_fw_callback parses the fw file | |
96 | * 8) iwl_req_fw_callback starts the wifi implementation to matches the fw | |
