218 | * The KLCONFIG area is organized as a LINKED LIST of BOARDs. A BOARD | |
219 | * can be either 'LOCAL' or 'REMOTE'. LOCAL means it is attached to | |
220 | * the LOCAL/current NODE. REMOTE means it is attached to a different | |
221 | * node.(TBD - Need a way to treat ROUTER boards.) | |
222 | * | |
223 | * There are 2 different structures to represent these boards - | |
224 | * lboard - Local board, rboard - remote board. These 2 structures | |
225 | * can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer | |
226 | * Figure below). The first byte of the rboard or lboard structure | |
227 | * is used to find out its type - no unions are used. | |
228 | * If it is a lboard, then the config info of this board will be found | |
229 | * on the local node. (LOCAL NODE BASE + offset value gives pointer to | |
230 | * the structure. | |
231 | * If it is a rboard, the local structure contains the node number | |
232 | * and the offset of the beginning of the LINKED LIST on the remote node. | |
233 | * The details of the hardware on a remote node can be built locally, | |
234 | * if required, by reading the LINKED LIST on the remote node and | |
235 | * ignoring all the rboards on that node. | |
236 | * | |
237 | * The local node uses the REMOTE NODE NUMBER + OFFSET to point to the | |
238 | * First board info on the remote node. The remote node list is | |
239 | * traversed as the local list, using the REMOTE BASE ADDRESS and not | |
240 | * the local base address and ignoring all rboard values. | |

268 | * | |
269 | * Each BOARD consists of COMPONENTs and the BOARD structure has | |
270 | * pointers (offsets) to its COMPONENT structure. | |
271 | * The COMPONENT structure has version info, size and speed info, revision, | |
272 | * error info and the NIC info. This structure can accommodate any | |
273 | * BOARD with arbitrary COMPONENT composition. | |
274 | * | |
275 | * The ERRORINFO part of each BOARD has error information | |
276 | * that describes errors about the BOARD itself. It also has flags to | |
277 | * indicate the COMPONENT(s) on the board that have errors. The error | |
278 | * information specific to the COMPONENT is present in the respective | |
279 | * COMPONENT structure. | |
280 | * | |
281 | * The ERRORINFO structure is also treated like a COMPONENT, ie. the | |
282 | * BOARD has pointers(offset) to the ERRORINFO structure. The rboard | |
283 | * structure also has a pointer to the ERRORINFO structure. This is | |
284 | * the place to store ERRORINFO about a REMOTE NODE, if the HUB on | |
285 | * that NODE is not working or if the REMOTE MEMORY is BAD. In cases where | |
286 | * only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can | |
287 | * be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info | |
288 | * which is present on the REMOTE NODE.(TBD) | |
289 | * REMOTE ERRINFO can be stored on any of the nearest nodes | |
290 | * or on all the nearest nodes.(TBD) | |
291 | * Like BOARD structures, REMOTE ERRINFO structures can be built locally | |
292 | * using the rboard errinfo pointer. | |
293 | * | |
294 | * In order to get useful information from this Data organization, a set of | |
295 | * interface routines are provided (TBD). The important thing to remember while | |
296 | * manipulating the structures, is that, the NODE number information should | |
297 | * be used. If the NODE is non-zero (remote) then each offset should | |
298 | * be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR. | |
299 | * This includes offsets for BOARDS, COMPONENTS and ERRORINFO. | |
300 | * | |
301 | * Note that these structures do not provide much info about connectivity. | |
302 | * That info will be part of HWGRAPH, which is an extension of the cfg_t | |
303 | * data structure. (ref IP27prom/cfg.h) It has to be extended to include | |
304 | * the IO part of the Network(TBD). | |
305 | * | |
306 | * The data structures below define the above concepts. | |
