+ *   hw.busfrequency_min       - All frequencies are in Hz.
+ *
+ *   hw.cputype                - These values provide the mach-o cpu type and subtype.  A complete list is in <mach/machine.h>
+ *   hw.cpusubtype             - These values should be used to determine what processor family the running cpu is from so that
+ *                               the best binary can be chosen, or the best dynamic code generated.  They should not be used
+ *                               to determine if a given processor feature is available.
+ *
+ *   hw.byteorder              - Gives the byte order of the processor.  4321 for big endian, 1234 for little.
+ *
+ *   hw.pagesize               - Gives the size in bytes of the pages used by the processor and VM system.
+ *
+ *   hw.cachelinesize          - Gives the size in bytes of the processor's cache lines.
+ *                               This value should be use to control the strides of loops that use cache control instructions
+ *                               like dcbz, dcbt or dcbst.
+ *
+ *   hw.l1dcachesize           - These values provide the size in bytes of the L1, L2 and L3 caches.  If a cache is not present
+ *   hw.l1icachesize           - then the selector will return and error.
+ *   hw.l2cachesize            -
+ *   hw.l3cachesize            -
+ *
+ *
+ * These are the selectors for optional processor features.  Selectors that return errors are not support on the system.
+ * Supported features will return 1 if they are recommended or 0 if they are supported but are not expected to help performance.
+ * Future versions of these selectors may return larger values as necessary so it is best to test for non zero.
+ *
+ *   hw.optional.floatingpoint - Floating Point Instructions
+ *   hw.optional.altivec       - AltiVec Instructions
+ *   hw.optional.graphicsops   - Graphics Operations
+ *   hw.optional.64bitops      - 64-bit Instructions
+ *   hw.optional.fsqrt         - HW Floating Point Square Root Instruction
+ *   hw.optional.stfiwx        - Store Floating Point as Integer Word Indexed Instructions
