DIMM + size and width (x4/x8) is assigned per dimm bank. Each DIMM bank + consists of 2 "physical banks", one on the front sides of the 2 + DIMMs and the other on the back sides. Therefore a node has a + total of 8 ( = 4 * 2) physical banks. They are collectively + referred to as "locational banks", since the locational bank number + depends on the physical location of the DIMMs on the board. + + Dimm bank 0, Phys bank 0a (locational bank 0a) + Slot D0 ---------------------------------------------- + Dimm bank 0, Phys bank 1a (locational bank 1a) + + Dimm bank 1, Phys bank 0a (locational bank 2a) + Slot D1 ---------------------------------------------- + Dimm bank 1, Phys bank 1a (locational bank 3a) + + Dimm bank 2, Phys bank 0a (locational bank 4a) + Slot D2 ---------------------------------------------- + Dimm bank 2, Phys bank 1a (locational bank 5a) + + Dimm bank 3, Phys bank 0a (locational bank 6a) + Slot D3 ---------------------------------------------- + Dimm bank 3, Phys bank 1a (locational bank 7a) + + Dimm bank 0, Phys bank 0b (locational bank 0b) + Slot D4 ---------------------------------------------- + Dimm bank 0, Phys bank 1b (locational bank 1b) + + Dimm bank 1, Phys bank 0b (locational bank 2b) + Slot D5 ---------------------------------------------- + Dimm bank 1, Phys bank 1b (locational bank 3b) + + Dimm bank 2, Phys bank 0b (locational bank 4b) + Slot D6 ---------------------------------------------- + Dimm bank 2, Phys bank 1b (locational bank 5b) + + Dimm bank 3, Phys bank 0b (locational bank 6b) + Slot D7 ---------------------------------------------- + Dimm bank 3, Phys bank 1b (locational bank 7b) + + Since bank size is assigned per DIMM bank, each pair of locational + banks must have the same size. However, they may be + enabled/disabled individually. + + The locational banks map to the software banks via the dimm0_sel + field in MD_MEMORY_CONFIG. When the field is 0 (the usual case), + the mapping is direct: eg. locational bank 1 (dimm bank 0, + physical bank 1, which is the back side of the first DIMM pair) + corresponds to software bank 1, at node offset 1GB. More + generally, locational bank = software bank XOR dimm0_sel. + + All the PROM's data structures (promlog variables, klconfig, etc.) + track memory by the locational bank number. The kernel usually + tracks memory by the software bank number. + memsupport.c:slot_psize_compute() performs the mapping. + + (Note: the terms "locational bank" and "software bank" are not + offical in any way, but I've tried to make the PROM use them + consistently -- bjj.) + */ + +#define MD_MEM_BANKS 8 +#define MD_MEM_DIMM_BANKS 4 +#define MD_BANK_SHFT 30 /* log2(1 GB) */ +#define MD_BANK_MASK (UINT64_CAST 0x7 << 30) +#define MD_BANK_SIZE (UINT64_CAST 1 << MD_BANK_SHFT) /* 1 GB */ +#define MD_BANK_OFFSET(_b) (UINT64_CAST (_b) << MD_BANK_SHFT) +#define MD_BANK_GET(addr) (((addr) & MD_BANK_MASK) >> MD_BANK_SHFT) +#define MD_BANK_TO_DIMM_BANK(_b) (( (_b) >> 1) & 0x3) +#define MD_BANK_TO_PHYS_BANK(_b) (( (_b) >> 0) & 0x1) +#define MD_DIMM_BANK_GET(addr) MD_BANK_TO_DIMM_BANK(MD_BANK_GET(addr)) +#define MD_PHYS_BANK_GET(addr) MD_BANK_TO_PHYS_BANK(MD_BANK_GET(addr)) + + +/* Split an MD pointer (or message source & suppl. fields) into node, device */ + +#define MD_PTR_NODE_SHFT 3 +#define MD_PTR_DEVICE_MASK 0x7 +#define MD_PTR_SUBNODE0_MASK 0x1 +#define MD_PTR_SUBNODE1_MASK 0x4 + + +/********************************************************************** + + Backdoor protection and page counter structures + +**********************************************************************/ + +/* Protection entries and page counters are interleaved at 4 separate + addresses, 0x10 apart.
