/*
|
|
* This file describes an interface to an IPMI driver. You have to
|
|
* have a fairly good understanding of IPMI to use this, so go read
|
|
* the specs first before actually trying to do anything.
|
|
*
|
|
* With that said, this driver provides a multi-user interface to the
|
|
* IPMI driver, and it allows multiple IPMI physical interfaces below
|
|
* the driver. The physical interfaces bind as a lower layer on the
|
|
* driver. They appear as interfaces to the application using this
|
|
* interface.
|
|
*
|
|
* Multi-user means that multiple applications may use the driver,
|
|
* send commands, receive responses, etc. The driver keeps track of
|
|
* commands the user sends and tracks the responses. The responses
|
|
* will go back to the application that send the command. If the
|
|
* response doesn't come back in time, the driver will return a
|
|
* timeout error response to the application. Asynchronous events
|
|
* from the BMC event queue will go to all users bound to the driver.
|
|
* The incoming event queue in the BMC will automatically be flushed
|
|
* if it becomes full and it is queried once a second to see if
|
|
* anything is in it. Incoming commands to the driver will get
|
|
* delivered as commands.
|
|
*
|
|
* This driver provides two main interfaces: one for in-kernel
|
|
* applications and another for userland applications. The
|
|
* capabilities are basically the same for both interface, although
|
|
* the interfaces are somewhat different. The stuff in the
|
|
* #ifdef KERNEL below is the in-kernel interface. The userland
|
|
* interface is defined later in the file. */
