- * DOC: Bus layer - role and goal
- *
- * iwl-bus.h defines the API to the bus layer of the iwlwifi driver.
- * The bus layer is responsible for doing very basic bus operations that are
- * listed in the iwl_bus_ops structure.
- * The bus layer registers to the bus driver, advertises the supported HW and
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c

- * DOC: encapsulation and type safety
- *
- * The iwl_bus describes the data that is shared amongst all the bus layer
- * implementations. This data is visible to other layers. Data in the bus
- * specific area is not visible outside the bus specific implementation.
- * iwl_bus holds a pointer to iwl_shared which holds pointer to all the other
- * layers of the driver (iwl_priv, iwl_trans). In fact, this is the way to go
- * when the transport layer needs to call a function of another layer.
- *
- * In order to achieve encapsulation, iwl_priv cannot be dereferenced from the
- * bus layer. Type safety is still kept since functions that gets iwl_priv gets
- * a typed pointer (as opposed to void *).

- * DOC: probe flow

- * will call the bus specific probe function.
- * The first thing this function must do is to allocate the memory needed by
- * iwl_bus + the bus_specific data.
- * Once the bus specific probe function has configured the hardware, it
- * chooses the appropriate transport layer and calls iwl_probe that will run
- * the bus independent probe flow.
- *
- * Note: The bus specific code must set the following data in iwl_bus before it

+/**
+ * DOC: Driver system flows - drv component
+ *
+ * This component implements the system flows such as bus enumeration, bus
+ * removal. Bus dependent parts of system flows (such as iwl_pci_probe) are in
+ * bus specific files (transport files). This is the code that is common among
+ * different buses.
+ *
+ * This component is also in charge of managing the several implementations of
+ * the wifi flows: it will allow to have several fw API implementation. These
+ * different implementations will differ in the way they implement mac80211's
+ * handlers too.
+
+ * The init flow wrt to the drv component looks like this:
+ * 1) The bus specific component is called from module_init
+ * 2) The bus specific component registers the bus driver
+ * 3) The bus driver calls the probe function
+ * 4) The bus specific component configures the bus
+ * 5) The bus specific component calls to the drv bus agnostic part
+ *    (iwl_drv_start)
+ * 6) iwl_drv_start fetches the fw ASYNC, iwl_ucode_callback
+ * 7) iwl_ucode_callback parses the fw file
+ * 8) iwl_ucode_callback starts the wifi implementation to matches the fw

+ * DOC: Operational mode - what is it ?
+ *
+ * The operational mode (a.k.a. op_mode) is the layer that implements
+ * mac80211's handlers. It knows two APIs: mac80211's and the fw's. It uses
+ * the transport API to access the HW. The op_mode doesn't need to know how the
+ * underlying HW works, since the transport layer takes care of that.
+ *
+ * There can be several op_mode: i.e. different fw APIs will require two
+ * different op_modes. This is why the op_mode is virtualized.
+ */
+
+/**
+ * DOC: Life cycle of the Operational mode
+ *
+ * The operational mode has a very simple life cycle.
+ *
+ *	1) The driver layer (iwl-drv.c) chooses the op_mode based on the
+ *	   capabilities advertized by the fw file (in TLV format).
+ *	2) The driver layer starts the op_mode (ops->start)
+ *	3) The op_mode registers registers mac80211
+ *	4) The op_mode is governed by mac80211
+ *	5) The driver layer stops the op_mode

+/**
+ * struct iwl_op_mode_ops - op_mode specific operations
+ *
+ * The op_mode exports its ops so that external components can start it and
+ * interact with it. The driver layer typically calls the start and stop
+ * handlers, the transport layer calls the others.
+ *
+ * All the handlers MUST be implemented
+ *
+ * @start: start the op_mode. The transport layer is already allocated.
+ *	May sleep
+ * @stop: stop the op_mode. Must free all the memory allocated.
+ *	May sleep
+ * @rx: Rx notification to the op_mode. rxb is the Rx buffer itself. Cmd is the
+ *	HCMD the this Rx responds to.
+ *	Must be atomic.
+ * @queue_full: notifies that a HW queue is full. Ac is the ac of the queue
+ *	Must be atomic
+ * @queue_not_full: notifies that a HW queue is not full any more.
+ *	Ac is the ac of the queue. Must be atomic
+ * @hw_rf_kill:notifies of a change in the HW rf kill switch. True means that
+ *	the radio is killed. Must be atomic.
+ * @free_skb: allows the transport layer to free skbs that haven't been
+ *	reclaimed by the op_mode. This can happen when the driver is freed and
+ *	there are Tx packets pending in the transport layer.
