11 | * | ||
12 | * Changes by Douglas "norsk" Thompson <dougthompson@xmission.com>: | ||
13 | * - K8 CPU Revision D and greater support | ||
14 | * | ||
15 | * Changes by Dave Peterson <dsp@llnl.gov> <dave_peterson@pobox.com>: | ||
16 | * - Module largely rewritten, with new (and hopefully correct) | ||
17 | * code for dealing with node and chip select interleaving, | ||
18 | * various code cleanup, and bug fixes | ||
19 | * - Added support for memory hoisting using DRAM hole address | ||
20 | * register | ||
21 | * | ||
22 | * Changes by Douglas "norsk" Thompson <dougthompson@xmission.com>: | ||
23 | * -K8 Rev (1207) revision support added, required Revision | ||
24 | * specific mini-driver code to support Rev F as well as | ||
25 | * prior revisions | ||
26 | * | ||
27 | * Changes by Douglas "norsk" Thompson <dougthompson@xmission.com>: | ||
28 | * -Family 10h revision support added. New PCI Device IDs, | ||
29 | * indicating new changes. Actual registers modified | ||
30 | * were slight, less than the Rev E to Rev F transition | ||
31 | * but changing the PCI Device ID was the proper thing to | ||
32 | * do, as it provides for almost automactic family | ||
33 | * detection. The mods to Rev F required more family | ||
34 | * information detection. | ||
35 | * | ||
36 | * Changes/Fixes by Borislav Petkov <borislav.petkov@amd.com>: | ||
37 | * - misc fixes and code cleanups | ||

83 | * Throughout the comments in this code, the following terms are used: | ||
84 | * | ||
85 | * SysAddr, DramAddr, and InputAddr | ||
86 | * | ||
87 | * These terms come directly from the amd64 documentation | ||
88 | * (AMD publication #26094). They are defined as follows: | ||
89 | * | ||
90 | * SysAddr: | ||
91 | * This is a physical address generated by a CPU core or a device | ||
92 | * doing DMA. If generated by a CPU core, a SysAddr is the result of | ||
93 | * a virtual to physical address translation by the CPU core's address | ||
94 | * translation mechanism (MMU). | ||
95 | * | ||
96 | * DramAddr: | ||
97 | * A DramAddr is derived from a SysAddr by subtracting an offset that | ||
98 | * depends on which node the SysAddr maps to and whether the SysAddr | ||
99 | * is within a range affected by memory hoisting. The DRAM Base | ||
100 | * (section 3.4.4.1) and DRAM Limit (section 3.4.4.2) registers | ||
101 | * determine which node a SysAddr maps to. | ||
102 | * | ||
103 | * If the DRAM Hole Address Register (DHAR) is enabled and the SysAddr | ||
104 | * is within the range of addresses specified by this register, then | ||
105 | * a value x from the DHAR is subtracted from the SysAddr to produce a | ||
106 | * DramAddr. Here, x represents the base address for the node that | ||
107 | * the SysAddr maps to plus an offset due to memory hoisting. See | ||
108 | * section 3.4.8 and the comments in amd64_get_dram_hole_info() and | ||
109 | * sys_addr_to_dram_addr() below for more information. | ||
110 | * | ||
111 | * If the SysAddr is not affected by the DHAR then a value y is | ||
112 | * subtracted from the SysAddr to produce a DramAddr. Here, y is the | ||
113 | * base address for the node that the SysAddr maps to. See section | ||
114 | * 3.4.4 and the comments in sys_addr_to_dram_addr() below for more | ||
115 | * information. | ||
116 | * | ||
117 | * InputAddr: | ||
118 | * A DramAddr is translated to an InputAddr before being passed to the | ||
119 | * memory controller for the node that the DramAddr is associated | ||
120 | * with. The memory controller then maps the InputAddr to a csrow. | ||
121 | * If node interleaving is not in use, then the InputAddr has the same | ||
122 | * value as the DramAddr. Otherwise, the InputAddr is produced by | ||
123 | * discarding the bits used for node interleaving from the DramAddr. | ||
124 | * See section 3.4.4 for more information. | ||
125 | * | ||
126 | * The memory controller for a given node uses its DRAM CS Base and | ||
127 | * DRAM CS Mask registers to map an InputAddr to a csrow. See | ||
128 | * sections 3.5.4 and 3.5.5 for more information. | ||
