-/*
- * These are the support HW selectors for sysctlbyname. Parameters that are byte count or frequencies are 64 bit numbers.
- * All other parameters are 32 bit numbers.
- *
- * hw.memsize - The number of bytes of physical memory in the system.
- *
- * hw.ncpu - The number maximum number of processor that could be available this boot.
- * Use this value for sizing of static per processor arrays; i.e. processor load statistics.
- *
- * hw.activecpu - The number of cpus currently available for executing threads.
- * Use this number to determine the number threads to create in SMP aware applications.
- * This number can change when power management modes are changed.
- *
- * hw.tbfrequency - This gives the time base frequency used by the OS and is the basis of all timing services.
- * In general is is better to use mach's or higher level timing services, but this value
- * is needed to convert the PPC Time Base registers to real time.
- *
- * hw.cpufrequency - These values provide the current, min and max cpu frequency. The min and max are for
- * hw.cpufrequency_max - all power management modes. The current frequency is the max frequency in the current mode.
- * hw.cpufrequency_min - All frequencies are in Hz.
- *
- * hw.busfrequency - These values provide the current, min and max bus frequency. The min and max are for
- * hw.busfrequency_max - all power management modes. The current frequency is the max frequency in the current mode.
- * 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
- * hw.optional.dcba - Data Cache Block Allocate Instruction
- * hw.optional.datastreams - Data Streams Instructions
- * hw.optional.dcbtstreams - Data Cache Block Touch Steams Instruction Form
