76 | * DOC: shared area - role and goal | |
77 | * | |
78 | * The shared area contains all the data exported by the upper layer to the | |
79 | * other layers. Since the bus and transport layer shouldn't dereference | |
80 | * iwl_priv, all the data needed by the upper layer and the transport / bus | |
81 | * layer must be here. | |
82 | * The shared area also holds pointer to all the other layers. This allows a | |
83 | * layer to call a function from another layer. | |
84 | * | |
85 | * NOTE: All the layers hold a pointer to the shared area which must be shrd. | |
86 | * A few macros assume that (_m)->shrd points to the shared area no matter | |
87 | * what _m is. | |
88 | * | |
89 | * gets notifications about enumeration, suspend, resume. | |
90 | * For the moment, the bus layer is not a linux kernel module as itself, and | |
91 | * the module_init function of the driver must call the bus specific | |
92 | * registration functions. These functions are listed at the end of this file. | |
93 | * For the moment, there is only one implementation of this interface: PCI-e. | |
94 | * This implementation is iwl-pci.c | |
