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.

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. */ /* * BOARD classes */ #define KLCLASS_MASK 0xf0 #define KLCLASS_NONE 0x00 #define KLCLASS_NODE 0x10 /* CPU, Memory and HUB board */ #define KLCLASS_CPU KLCLASS_NODE #define KLCLASS_IO 0x20 /* BaseIO, 4 ch SCSI, ethernet, FDDI and the non-graphics widget boards */ #define KLCLASS_ROUTER 0x30 /* Router board */ #define KLCLASS_MIDPLANE 0x40 /* We need to treat this as a board so that we can record error info */ #define KLCLASS_IOBRICK 0x70 /* IP35 iobrick */ #define KLCLASS_MAX 8 /* Bump this if a new CLASS is added */ #define KLCLASS(_x) ((_x) & KLCLASS_MASK) /* * board types */ #define KLTYPE_MASK 0x0f #define KLTYPE(_x) ((_x) & KLTYPE_MASK) #define KLTYPE_SNIA (KLCLASS_CPU | 0x1) #define KLTYPE_TIO (KLCLASS_CPU | 0x2) #define KLTYPE_ROUTER (KLCLASS_ROUTER | 0x1) #define KLTYPE_META_ROUTER (KLCLASS_ROUTER | 0x3) #define KLTYPE_REPEATER_ROUTER (KLCLASS_ROUTER | 0x4) #define KLTYPE_IOBRICK_XBOW (KLCLASS_MIDPLANE | 0x2) #define KLTYPE_IOBRICK (KLCLASS_IOBRICK | 0x0) #define KLTYPE_NBRICK (KLCLASS_IOBRICK | 0x4) #define KLTYPE_PXBRICK (KLCLASS_IOBRICK | 0x6) #define KLTYPE_IXBRICK (KLCLASS_IOBRICK | 0x7) #define KLTYPE_CGBRICK (KLCLASS_IOBRICK | 0x8) #define KLTYPE_OPUSBRICK (KLCLASS_IOBRICK | 0x9) #define KLTYPE_SABRICK (KLCLASS_IOBRICK | 0xa) #define KLTYPE_IABRICK (KLCLASS_IOBRICK | 0xb) #define KLTYPE_PABRICK (KLCLASS_IOBRICK | 0xc) #define KLTYPE_GABRICK (KLCLASS_IOBRICK | 0xd) /* * board structures */ #define MAX_COMPTS_PER_BRD 24 typedef struct lboard_s { klconf_off_t brd_next_any; /* Next BOARD */ unsigned char struct_type; /* type of structure, local or remote */ unsigned char brd_type; /* type+class */ unsigned char brd_sversion; /* version of this structure */ unsigned char brd_brevision; /* board revision */ unsigned char brd_promver; /* board prom version, if any */ unsigned char brd_flags; /* Enabled, Disabled etc */ unsigned char brd_slot; /* slot number */ unsigned short brd_debugsw; /* Debug switches */ geoid_t brd_geoid; /* geo id */ partid_t brd_partition; /* Partition number */ unsigned short brd_diagval; /* diagnostic value */ unsigned short brd_diagparm; /* diagnostic parameter */ unsigned char brd_inventory; /* inventory history */ unsigned char brd_numcompts; /* Number of components */ nic_t brd_nic; /* Number in CAN */ nasid_t brd_nasid; /* passed parameter */ klconf_off_t brd_compts[MAX_COMPTS_PER_BRD]; /* pointers to COMPONENTS */ klconf_off_t brd_errinfo; /* Board's error information */ struct lboard_s *brd_parent; /* Logical parent for this brd */ char pad0[4]; unsigned char brd_confidence; /* confidence that the board is bad */ nasid_t brd_owner; /* who owns this board */ unsigned char brd_nic_flags; /* To handle 8 more NICs */ char pad1[24]; /* future expansion */ char brd_name[32]; nasid_t brd_next_same_host; /* host of next brd w/same nasid */ klconf_off_t brd_next_same; /* Next BOARD with same nasid */ } lboard_t; /* * Generic info structure.
