This lets us overload the macros so that the addition * of the CTLFLAG_OID2 in newly compiled code containing sysctl * node declarations, subsequently allowing us to to avoid * changing the KPI used for non-static (un)registration in * KEXTs. * * This depends on the fact that people declare SYSCTLs, * rather than declaring sysctl_oid structures.

/* * XXX This information should be moved to the man page. * * These are the support HW selectors for sysctlbyname. Parameters that are byte counts 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 maximum number of processors 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 processors 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.physicalcpu - The number of physical processors available in the current power management mode. * hw.physicalcpu_max - The maximum number of physical processors that could be available this boot * * hw.logicalcpu - The number of logical processors available in the current power management mode. * hw.logicalcpu_max - The maximum number of logical processors that could be available this boot * * 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.cputhreadtype - This value will be present if the processor supports threads. Like hw.cpusubtype this selector * should not be used to infer features, and only used to name the processors thread architecture. * The values are defined in <mach/machine.h> * * 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 - * * hw.packages - Gives the number of processor packages. * * These are the selectors for optional processor features for specific processors. 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. * * For PowerPC: * * 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 * * For x86 Architecture: * * hw.optional.floatingpoint - Floating Point Instructions * hw.optional.mmx - Original MMX vector instructions * hw.optional.sse - Streaming SIMD Extensions * hw.optional.sse2 - Streaming SIMD Extensions 2 * hw.optional.sse3 - Streaming SIMD Extensions 3 * hw.optional.supplementalsse3 - Supplemental Streaming SIMD Extensions 3 * hw.optional.x86_64 - 64-bit support */
