2 | * include/linux/node.h - generic node definition |
||
3 | * |
||
4 | * This is mainly for topological representation. We define the |
||
5 | * basic 'struct node' here, which can be embedded in per-arch |
||
6 | * definitions of processors. |
||
7 | * |
||
8 | * Basic handling of the devices is done in drivers/base/node.c |
||
9 | * and system devices are handled in drivers/base/sys.c. |
||
10 | * |
||
11 | * Nodes are exported via driverfs in the class/node/devices/ |
||
12 | * directory. |
||
13 | * |
||
14 | * Per-node interfaces can be implemented using a struct device_interface. |
||
15 | * See the following for how to do this: |
||
16 | * - drivers/base/intf.c |
||
17 | * - Documentation/driver-model/interface.txt |
