- *
- * 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
- *
