- /* Like SN0, SN1 supports a mostly-flat address space with 8
- CPU-visible, evenly spaced, contiguous regions, or "software
- banks". On SN1, software bank n begins at addresses n * 1GB,
- 0 <= n < 8.
- Physically (and very unlike SN0), each SN1 node board contains 8
- dimm sockets, arranged as 4 "DIMM banks" of 2 dimms each. 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.)
