40 | * Throughout the comments in this code, the following terms are used: | |
41 | * | |
42 | * SysAddr, DramAddr, and InputAddr | |
43 | * | |
44 | * These terms come directly from the amd64 documentation | |
45 | * (AMD publication #26094). They are defined as follows: | |
46 | * | |
47 | * SysAddr: | |
48 | * This is a physical address generated by a CPU core or a device | |
49 | * doing DMA. If generated by a CPU core, a SysAddr is the result of | |
50 | * a virtual to physical address translation by the CPU core's address | |
51 | * translation mechanism (MMU). | |
52 | * | |
53 | * DramAddr: | |
54 | * A DramAddr is derived from a SysAddr by subtracting an offset that | |
55 | * depends on which node the SysAddr maps to and whether the SysAddr | |
56 | * is within a range affected by memory hoisting. The DRAM Base | |
57 | * (section 3.4.4.1) and DRAM Limit (section 3.4.4.2) registers | |
58 | * determine which node a SysAddr maps to. | |
59 | * | |
60 | * If the DRAM Hole Address Register (DHAR) is enabled and the SysAddr | |
61 | * is within the range of addresses specified by this register, then | |
62 | * a value x from the DHAR is subtracted from the SysAddr to produce a | |
63 | * DramAddr. Here, x represents the base address for the node that | |
64 | * the SysAddr maps to plus an offset due to memory hoisting. See | |
65 | * section 3.4.8 and the comments in amd64_get_dram_hole_info() and | |
66 | * sys_addr_to_dram_addr() below for more information. | |
67 | * | |
68 | * If the SysAddr is not affected by the DHAR then a value y is | |
69 | * subtracted from the SysAddr to produce a DramAddr. Here, y is the | |
70 | * base address for the node that the SysAddr maps to. See section | |
71 | * 3.4.4 and the comments in sys_addr_to_dram_addr() below for more | |
72 | * information. | |
73 | * | |
74 | * InputAddr: | |
75 | * A DramAddr is translated to an InputAddr before being passed to the | |
76 | * memory controller for the node that the DramAddr is associated | |
77 | * with. The memory controller then maps the InputAddr to a csrow. | |
78 | * If node interleaving is not in use, then the InputAddr has the same | |
79 | * value as the DramAddr. Otherwise, the InputAddr is produced by | |
80 | * discarding the bits used for node interleaving from the DramAddr. | |
81 | * See section 3.4.4 for more information. | |
82 | * | |
83 | * The memory controller for a given node uses its DRAM CS Base and | |
84 | * DRAM CS Mask registers to map an InputAddr to a csrow. See | |
85 | * sections 3.5.4 and 3.5.5 for more information. | |
