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. * * KLCONFIG +------------+ +------------+ +------------+ +------------+ | lboard | +-->| lboard | +-->| rboard | +-->| lboard | +------------+ | +------------+ | +------------+ | +------------+ | board info | | | board info | | |errinfo,bptr| | | board info | +------------+ | +------------+ | +------------+ | +------------+ | offset |--+ | offset |--+ | offset |--+ |offset=NULL | +------------+ +------------+ +------------+ +------------+ +------------+ | board info | +------------+ +--------------------------------+ | compt 1 |------>| type, rev, diaginfo, size ... | (CPU) +------------+ +--------------------------------+ | compt 2 |--+ +------------+ | +--------------------------------+ | ... | +--->| type, rev, diaginfo, size ... | (MEM_BANK) +------------+ +--------------------------------+ | errinfo |--+ +------------+ | +--------------------------------+ +--->|r/l brd errinfo,compt err flags | +--------------------------------+ * * 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. */ /* * Values for CPU types */ #define KL_CPU_R4000 0x1 /* Standard R4000 */ #define KL_CPU_TFP 0x2 /* TFP processor */ #define KL_CPU_R10000 0x3 /* R10000 (T5) */ #define KL_CPU_NONE (-1) /* no cpu present in slot */ /* * IP27 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_GFX 0x50 /* graphics boards */ #define KLCLASS_PSEUDO_GFX 0x60 /* HDTV type cards that use a gfx * hw ifc to xtalk and are not gfx * class for sw purposes */ #define KLCLASS_MAX 7 /* Bump this if a new CLASS is added */ #define KLTYPE_MAX 10 /* Bump this if a new CLASS is added */ #define KLCLASS_UNKNOWN 0xf0 #define KLCLASS(_x) ((_x) & KLCLASS_MASK) /* * IP27 board types */ #define KLTYPE_MASK 0x0f #define KLTYPE_NONE 0x00 #define KLTYPE_EMPTY 0x00 #define KLTYPE_WEIRDCPU (KLCLASS_CPU | 0x0) #define KLTYPE_IP27 (KLCLASS_CPU | 0x1) /* 2 CPUs(R10K) per board */ #define KLTYPE_WEIRDIO (KLCLASS_IO | 0x0) #define KLTYPE_BASEIO (KLCLASS_IO | 0x1) /* IOC3, SuperIO, Bridge, SCSI */ #define KLTYPE_IO6 KLTYPE_BASEIO /* Additional name */ #define KLTYPE_4CHSCSI (KLCLASS_IO | 0x2) #define KLTYPE_MSCSI KLTYPE_4CHSCSI /* Additional name */ #define KLTYPE_ETHERNET (KLCLASS_IO | 0x3) #define KLTYPE_MENET KLTYPE_ETHERNET /* Additional name */ #define KLTYPE_FDDI (KLCLASS_IO | 0x4) #define KLTYPE_UNUSED (KLCLASS_IO | 0x5) /* XXX UNUSED */ #define KLTYPE_HAROLD (KLCLASS_IO | 0x6) /* PCI SHOE BOX */ #define KLTYPE_PCI KLTYPE_HAROLD #define KLTYPE_VME (KLCLASS_IO | 0x7) /* Any 3rd party VME card */ #define KLTYPE_MIO (KLCLASS_IO | 0x8) #define KLTYPE_FC (KLCLASS_IO | 0x9) #define KLTYPE_LINC (KLCLASS_IO | 0xA) #define KLTYPE_TPU (KLCLASS_IO | 0xB) /* Tensor Processing Unit */ #define KLTYPE_GSN_A (KLCLASS_IO | 0xC) /* Main GSN board */ #define KLTYPE_GSN_B (KLCLASS_IO | 0xD) /* Auxiliary GSN board */ #define KLTYPE_GFX (KLCLASS_GFX | 0x0) /* unknown graphics type */ #define KLTYPE_GFX_KONA (KLCLASS_GFX | 0x1) /* KONA graphics on IP27 */ #define KLTYPE_GFX_MGRA (KLCLASS_GFX | 0x3) /* MGRAS graphics on IP27 */ #define KLTYPE_WEIRDROUTER (KLCLASS_ROUTER | 0x0) #define KLTYPE_ROUTER (KLCLASS_ROUTER | 0x1) #define KLTYPE_ROUTER2 KLTYPE_ROUTER /* Obsolete! */ #define KLTYPE_NULL_ROUTER (KLCLASS_ROUTER | 0x2) #define KLTYPE_META_ROUTER (KLCLASS_ROUTER | 0x3) #define KLTYPE_WEIRDMIDPLANE (KLCLASS_MIDPLANE | 0x0) #define KLTYPE_MIDPLANE8 (KLCLASS_MIDPLANE | 0x1) /* 8 slot backplane */ #define KLTYPE_MIDPLANE KLTYPE_MIDPLANE8 #define KLTYPE_PBRICK_XBOW (KLCLASS_MIDPLANE | 0x2) #define KLTYPE_IOBRICK (KLCLASS_IOBRICK | 0x0) #define KLTYPE_IBRICK (KLCLASS_IOBRICK | 0x1) #define KLTYPE_PBRICK (KLCLASS_IOBRICK | 0x2) #define KLTYPE_XBRICK (KLCLASS_IOBRICK | 0x3) #define KLTYPE_PBRICK_BRIDGE KLTYPE_PBRICK /* The value of type should be more than 8 so that hinv prints * out the board name from the NIC string.
