You have to 42 * have a fairly good understanding of IPMI to use this, so go read 43 * the specs first before actually trying to do anything. 44 * 45 * With that said, this driver provides a multi-user interface to the 46 * IPMI driver, and it allows multiple IPMI physical interfaces below 47 * the driver. The physical interfaces bind as a lower layer on the 48 * driver. They appear as interfaces to the application using this 49 * interface. 50 * 51 * Multi-user means that multiple applications may use the driver, 52 * send commands, receive responses, etc. The driver keeps track of 53 * commands the user sends and tracks the responses. The responses 54 * will go back to the application that send the command. If the 55 * response doesn't come back in time, the driver will return a 56 * timeout error response to the application. Asynchronous events 57 * from the BMC event queue will go to all users bound to the driver. 58 * The incoming event queue in the BMC will automatically be flushed 59 * if it becomes full and it is queried once a second to see if 60 * anything is in it. Incoming commands to the driver will get 61 * delivered as commands. 62 * 63 * This driver provides two main interfaces: one for in-kernel 64 * applications and another for userland applications. The 65 * capabilities are basically the same for both interface, although 66 * the interfaces are somewhat different. The stuff in the 67 * #ifdef KERNEL below is the in-kernel interface. The userland 68 * interface is defined later in the file. */ 69 70 71 72 /* 73 * This is an overlay for all the address types, so it's easy to 74 * determine the actual address type.
