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

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

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

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