38  * The mc-amd driver exports an nvlist to userland, where the primary
39  * consumer is the "chip" topology enumerator for this platform type which
40  * builds a full topology subtree from this information.  Others can use
41  * it, too, but don't depend on it not changing without an ARC contract
42  * (and the contract should probably concern the topology, not this nvlist).
43  *
44  * In the initial mc-amd implementation this nvlist was not versioned;
45  * we'll think of that as version 0 and it may be recognised by the absence
46  * of a "mcamd-nvlist-version member.
47  *
48  * Version 1 is defined as follows.  A name in square brackets indicates
49  * that member is optional (only present if the actual value is valid).

166  * Memory controller registers are read via PCI config space accesses on

169  * Function 0: HyperTransport Technology Configuration
170  * Function 1: Address Map
171  * Function 2: DRAM Controller & HyperTransport Technology Trace Mode
172  * Function 3: Miscellaneous Control
173  *
174  * For a given (bus, device, function) a particular offset selects the
175  * desired register.  All registers are 32-bits wide.
176  *
177  * Different family 0xf processor revisions vary slightly in the content
178  * of these configuration registers.  The biggest change is with rev F
179  * where DDR2 support has been introduced along with some hardware-controlled
180  * correctable memory error thresholding.  Fortunately most of the config info
181  * required by the mc-amd driver is similar across revisions.
182  *
183  * We will try to insulate most of the driver code from config register
184  * details by reading all memory-controller PCI config registers that we
185  * will need at driver attach time for each of functions 0 through 3, and
186  * storing them in a "cooked" form as memory controller properties.
187  * These are to be accessed directly where we have an mc_t to hand, otherwise
188  * through mcamd_get_numprop.  As such we expect most/all use of the
189  * structures and macros defined below to be in those attach codepaths.

193  * Registers will be represented as unions, with one fixed-width unsigned
194  * integer member providing access to the raw register value and one or more
195  * structs breaking the register out into bitfields (more than one struct if
196  * the register definitions varies across processor revisions).
197  *
198  * The "raw" union member will always be '_val32'.  Use MCREG_VAL32 to
199  * access this member.
200  *
201  * The bitfield structs are all named _fmt_xxx where xxx identifies the
202  * processor revision to which it applies.  At this point the only xxx
203  * values in use are:
204  *			'cmn' - applies to all revisions
205  *			'preF' - applies to revisions E and earlier
206  *			'revFG' - applies to revisions F and G
207  * Variants such as 'preD', 'revDE', 'postCG' etc should be introduced
208  * as requirements arise.  The MC_REV_* and MC_REV_MATCH etc macros
209  * will also need to grow to match.  Use MCREG_FIELD_* to access the
210  * individual bitfields of a register, perhaps using MC_REV_* and MC_REV_MATCH
211  * to decide which revision suffix to provide.  Where a bitfield appears
212  * in different revisions but has the same use it should be named identically
213  * (even if the BKDG varies a little) so that the MC_REG_FIELD_* macros
214  * can lookup that member based on revision only.
