27 | * Addressing Terminology | |
28 | * | |
9f5314fb JS |
29 | * M - The low M bits of a physical address represent the offset |
30 | * into the blade local memory. RAM memory on a blade is physically | |
31 | * contiguous (although various IO spaces may punch holes in | |
32 | * it).. | |
952cf6d7 | 33 | * |
39d30770 MT |
34 | * N - Number of bits in the node portion of a socket physical |
35 | * address. | |
9f5314fb | 36 | * |
39d30770 MT |
37 | * NASID - network ID of a router, Mbrick or Cbrick. Nasid values of |
38 | * routers always have low bit of 1, C/MBricks have low bit | |
39 | * equal to 0. Most addressing macros that target UV hub chips | |
40 | * right shift the NASID by 1 to exclude the always-zero bit. | |
41 | * NASIDs contain up to 15 bits. | |
9f5314fb JS |
42 | * |
43 | * GNODE - NASID right shifted by 1 bit. Most mmrs contain gnodes instead | |
44 | * of nasids. | |
45 | * | |
39d30770 MT |
46 | * PNODE - the low N bits of the GNODE. The PNODE is the most useful variant |
47 | * of the nasid for socket usage. | |
9f5314fb JS |
48 | * |
49 | * | |
50 | * NumaLink Global Physical Address Format: | |
51 | * +--------------------------------+---------------------+ | |
52 | * |00..000| GNODE | NodeOffset | | |
53 | * +--------------------------------+---------------------+ | |
54 | * |<-------53 - M bits --->|<--------M bits -----> | |
55 | * | |
56 | * M - number of node offset bits (35 .. 40) | |
952cf6d7 JS |
57 | * |
58 | * | |
59 | * Memory/UV-HUB Processor Socket Address Format: | |
9f5314fb JS |
60 | * +----------------+---------------+---------------------+ |
61 | * |00..000000000000| PNODE | NodeOffset | | |
62 | * +----------------+---------------+---------------------+ | |
63 | * <--- N bits --->|<--------M bits -----> | |
952cf6d7 | 64 | * |
9f5314fb JS |
65 | * M - number of node offset bits (35 .. 40) |
66 | * N - number of PNODE bits (0 .. 10) | |
952cf6d7 JS |
67 | * |
68 | * Note: M + N cannot currently exceed 44 (x86_64) or 46 (IA64). | |
69 | * The actual values are configuration dependent and are set at | |
9f5314fb JS |
70 | * boot time. M & N values are set by the hardware/BIOS at boot. |
71 | * | |
952cf6d7 JS |
72 | * |
73 | * APICID format | |
39d30770 MT |
74 | * NOTE!!!!!! This is the current format of the APICID. However, code |
75 | * should assume that this will change in the future. Use functions | |
76 | * in this file for all APICID bit manipulations and conversion. | |
