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.

59 * Sections in the first 2 documents are no longer in sync with each other.
60 * The Family 10h BKDG was totally re-written from scratch with a new

99 * Throughout the comments in this code, the following terms are used:
100 *
101 * SysAddr, DramAddr, and InputAddr
102 *
103 * These terms come directly from the amd64 documentation
104 * (AMD publication #26094). They are defined as follows:
105 *
106 * SysAddr:
107 * This is a physical address generated by a CPU core or a device
108 * doing DMA. If generated by a CPU core, a SysAddr is the result of
109 * a virtual to physical address translation by the CPU core's address
110 * translation mechanism (MMU).
111 *
112 * DramAddr:
113 * A DramAddr is derived from a SysAddr by subtracting an offset that
114 * depends on which node the SysAddr maps to and whether the SysAddr
115 * is within a range affected by memory hoisting. The DRAM Base
116 * (section 3.4.4.1) and DRAM Limit (section 3.4.4.2) registers
117 * determine which node a SysAddr maps to.
118 *
119 * If the DRAM Hole Address Register (DHAR) is enabled and the SysAddr
120 * is within the range of addresses specified by this register, then
121 * a value x from the DHAR is subtracted from the SysAddr to produce a
122 * DramAddr. Here, x represents the base address for the node that
123 * the SysAddr maps to plus an offset due to memory hoisting. See
124 * section 3.4.8 and the comments in amd64_get_dram_hole_info() and
125 * sys_addr_to_dram_addr() below for more information.
126 *
127 * If the SysAddr is not affected by the DHAR then a value y is
128 * subtracted from the SysAddr to produce a DramAddr. Here, y is the
129 * base address for the node that the SysAddr maps to. See section
130 * 3.4.4 and the comments in sys_addr_to_dram_addr() below for more
131 * information.
132 *
133 * InputAddr:
134 * A DramAddr is translated to an InputAddr before being passed to the
135 * memory controller for the node that the DramAddr is associated
136 * with. The memory controller then maps the InputAddr to a csrow.
137 * If node interleaving is not in use, then the InputAddr has the same
138 * value as the DramAddr. Otherwise, the InputAddr is produced by
139 * discarding the bits used for node interleaving from the DramAddr.
140 * See section 3.4.4 for more information.
141 *
142 * The memory controller for a given node uses its DRAM CS Base and
143 * DRAM CS Mask registers to map an InputAddr to a csrow. See
144 * sections 3.5.4 and 3.5.5 for more information.
