After moving the the include files there were a few clean-ups: 1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h> 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references.

* The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD
|
|
* can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to
|
|
* the LOCAL/current NODE. REMOTE means it is attached to a different
|
|
* node.(TBD - Need a way to treat ROUTER boards.)
|
|
*
|
|
* There are 2 different structures to represent these boards -
|
|
* lboard - Local board, rboard - remote board. These 2 structures
|
|
* can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
|
|
* Figure below). The first byte of the rboard or lboard structure
|
|
* is used to find out its type - no unions are used.
|
|
* If it is a lboard, then the config info of this board will be found
|
|
* on the local node. (LOCAL NODE BASE + offset value gives pointer to
|
|
* the structure.
|
|
* If it is a rboard, the local structure contains the node number
|
|
* and the offset of the beginning of the LINKED LIST on the remote node.
|
|
* The details of the hardware on a remote node can be built locally,
|
|
* if required, by reading the LINKED LIST on the remote node and
|
|
* ignoring all the rboards on that node.
|
|
*
|
|
* The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
|
|
* First board info on the remote node. The remote node list is
|
|
* traversed as the local list, using the REMOTE BASE ADDRESS and not
|
|
* the local base address and ignoring all rboard values.

|
|
* Each BOARD consists of COMPONENTs and the BOARD structure has
|
|
* pointers (offsets) to its COMPONENT structure.
|
|
* The COMPONENT structure has version info, size and speed info, revision,
|
|
* error info and the NIC info. This structure can accommodate any
|
|
* BOARD with arbitrary COMPONENT composition.
|
|
*
|
|
* The ERRORINFO part of each BOARD has error information
|
|
* that describes errors about the BOARD itself. It also has flags to
|
|
* indicate the COMPONENT(s) on the board that have errors. The error
|
|
* information specific to the COMPONENT is present in the respective
|
|
* COMPONENT structure.
|
|
*
|
|
* The ERRORINFO structure is also treated like a COMPONENT, ie. the
|
|
* BOARD has pointers(offset) to the ERRORINFO structure. The rboard
|
|
* structure also has a pointer to the ERRORINFO structure. This is
|
|
* the place to store ERRORINFO about a REMOTE NODE, if the HUB on
|
|
* that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
|
|
* only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
|
|
* be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
|
|
* which is present on the REMOTE NODE.(TBD)
|
|
* REMOTE ERRINFO can be stored on any of the nearest nodes
|
|
* or on all the nearest nodes.(TBD)
|
|
* Like BOARD structures, REMOTE ERRINFO structures can be built locally
|
|
* using the rboard errinfo pointer.
|
|
*
|
|
* In order to get useful information from this Data organization, a set of
|
|
* interface routines are provided (TBD). The important thing to remember while
|
|
* manipulating the structures, is that, the NODE number information should
|
|
* be used. If the NODE is non-zero (remote) then each offset should
|
|
* be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
|
|
* This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
|
|
*
|
|
* Note that these structures do not provide much info about connectivity.
|
|
* That info will be part of HWGRAPH, which is an extension of the cfg_t
|
|
* data structure. (ref IP27prom/cfg.h) It has to be extended to include
|
|
* the IO part of the Network(TBD).
|
|
*
|
|
* The data structures below define the above concepts.
