+ *
+ * -----------------------------------------------------------
+ * |impl-vers| RSV |TC|AC|SP|BM|PC|MBM|SB|IC|DC|PSO|RSV|NF|ME|
+ * -----------------------------------------------------------
+ *  31     24 23-17 16 15 14 13 12 11  10  9  8  7  6-2  1  0
+ *
+ * TC: Tablewalk Cacheable -- 0 = Twalks are not cacheable in E-cache
+ *                            1 = Twalks are cacheable in E-cache
+ *
+ * GNU/Viking will only cache tablewalks in the E-cache (mxcc) if present
+ * and never caches them internally (or so states the docs).  Therefore
+ * for machines lacking an E-cache (ie. in MBUS mode) this bit must
+ * remain cleared.
+ *
+ * AC: Alternate Cacheable -- 0 = Passthru physical accesses not cacheable
+ *                            1 = Passthru physical accesses cacheable
+ *
+ * This indicates whether accesses are cacheable when no cachable bit
+ * is present in the pte when the processor is in boot-mode or the
+ * access does not need pte's for translation (ie. pass-thru ASI's).
+ * "Cachable" is only referring to E-cache (if present) and not the
+ * on chip split I/D caches of the GNU/Viking.
+ *
+ * SP: SnooP Enable -- 0 = bus snooping off, 1 = bus snooping on
+ *
+ * This enables snooping on the GNU/Viking bus.  This must be on
+ * for the hardware cache consistency mechanisms of the GNU/Viking
+ * to work at all.  On non-mxcc GNU/Viking modules the split I/D
+ * caches will snoop regardless of whether they are enabled, this
+ * takes care of the case where the I or D or both caches are turned
+ * off yet still contain valid data.  Note also that this bit does
+ * not affect GNU/Viking store-buffer snoops, those happen if the
+ * store-buffer is enabled no matter what.
+ *
+ * BM: Boot Mode -- 0 = not in boot mode, 1 = in boot mode
+ *
+ * This indicates whether the GNU/Viking is in boot-mode or not,
+ * if it is then all instruction fetch physical addresses are
+ * computed as 0xff0000000 + low 28 bits of requested address.
+ * GNU/Viking boot-mode does not affect data accesses.  Also,
+ * in boot mode instruction accesses bypass the split on chip I/D
+ * caches, they may be cached by the GNU/MXCC if present and enabled.
+ *
+ * MBM: MBus Mode -- 0 = not in MBus mode, 1 = in MBus mode
+ *
+ * This indicated the GNU/Viking configuration present.  If in
+ * MBUS mode, the GNU/Viking lacks a GNU/MXCC E-cache.  If it is
+ * not then the GNU/Viking is on a module VBUS connected directly
+ * to a GNU/MXCC cache controller.  The GNU/MXCC can be thus connected
+ * to either an GNU/MBUS (sun4m) or the packet-switched GNU/XBus (sun4d).
+ *
+ * SB: StoreBuffer enable -- 0 = store buffer off, 1 = store buffer on
+ *
+ * The GNU/Viking store buffer allows the chip to continue execution
+ * after a store even if the data cannot be placed in one of the
+ * caches during that cycle.  If disabled, all stores operations
+ * occur synchronously.
+ *
+ * IC: Instruction Cache -- 0 = off, 1 = on
+ * DC: Data Cache -- 0 = off, 1 = 0n
+ *
+ * These bits enable the on-cpu GNU/Viking split I/D caches.  Note,
+ * as mentioned above, these caches will snoop the bus in GNU/MBUS
+ * configurations even when disabled to avoid data corruption.
+ *
+ * NF: No Fault -- 0 = faults generate traps, 1 = faults don't trap
+ * ME: MMU enable -- 0 = mmu not translating, 1 = mmu translating
+ *
