40 | /* | ||
41 | * This file describes an interface to an IPMI driver. 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. */ | ||

516 | * incoming messages are for which command and find the proper msgid | ||
