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 * */ /* * CTL_USER definitions */ #define USER_CS_PATH 1 /* string: _CS_PATH */ #define USER_BC_BASE_MAX 2 /* int: BC_BASE_MAX */ #define USER_BC_DIM_MAX 3 /* int: BC_DIM_MAX */ #define USER_BC_SCALE_MAX 4 /* int: BC_SCALE_MAX */ #define USER_BC_STRING_MAX 5 /* int: BC_STRING_MAX */ #define USER_COLL_WEIGHTS_MAX 6 /* int: COLL_WEIGHTS_MAX */ #define USER_EXPR_NEST_MAX 7 /* int: EXPR_NEST_MAX */ #define USER_LINE_MAX 8 /* int: LINE_MAX */ #define USER_RE_DUP_MAX 9 /* int: RE_DUP_MAX */ #define USER_POSIX2_VERSION 10 /* int: POSIX2_VERSION */ #define USER_POSIX2_C_BIND 11 /* int: POSIX2_C_BIND */ #define USER_POSIX2_C_DEV 12 /* int: POSIX2_C_DEV */ #define USER_POSIX2_CHAR_TERM 13 /* int: POSIX2_CHAR_TERM */ #define USER_POSIX2_FORT_DEV 14 /* int: POSIX2_FORT_DEV */ #define USER_POSIX2_FORT_RUN 15 /* int: POSIX2_FORT_RUN */ #define USER_POSIX2_LOCALEDEF 16 /* int: POSIX2_LOCALEDEF */ #define USER_POSIX2_SW_DEV 17 /* int: POSIX2_SW_DEV */ #define USER_POSIX2_UPE 18 /* int: POSIX2_UPE */ #define USER_STREAM_MAX 19 /* int: POSIX2_STREAM_MAX */ #define USER_TZNAME_MAX 20 /* int: POSIX2_TZNAME_MAX */ #define USER_MAXID 21 /* number of valid user ids */ #define CTL_USER_NAMES { \ { 0, 0 }, \ { "cs_path", CTLTYPE_STRING }, \ { "bc_base_max", CTLTYPE_INT }, \ { "bc_dim_max", CTLTYPE_INT }, \ { "bc_scale_max", CTLTYPE_INT }, \ { "bc_string_max", CTLTYPE_INT }, \ { "coll_weights_max", CTLTYPE_INT }, \ { "expr_nest_max", CTLTYPE_INT }, \ { "line_max", CTLTYPE_INT }, \ { "re_dup_max", CTLTYPE_INT }, \ { "posix2_version", CTLTYPE_INT }, \ { "posix2_c_bind", CTLTYPE_INT }, \ { "posix2_c_dev", CTLTYPE_INT }, \ { "posix2_char_term", CTLTYPE_INT }, \ { "posix2_fort_dev", CTLTYPE_INT }, \ { "posix2_fort_run", CTLTYPE_INT }, \ { "posix2_localedef", CTLTYPE_INT }, \ { "posix2_sw_dev", CTLTYPE_INT }, \ { "posix2_upe", CTLTYPE_INT }, \ { "stream_max", CTLTYPE_INT }, \ { "tzname_max", CTLTYPE_INT } \ } /* * CTL_DEBUG definitions * * Second level identifier specifies which debug variable. * Third level identifier specifies which stucture component. */ #define CTL_DEBUG_NAME 0 /* string: variable name */ #define CTL_DEBUG_VALUE 1 /* int: variable value */ #define CTL_DEBUG_MAXID 20 #ifdef KERNEL #ifdef __APPLE_API_UNSTABLE extern struct sysctl_oid_list sysctl__children; SYSCTL_DECL(_kern); SYSCTL_DECL(_sysctl); SYSCTL_DECL(_vm); SYSCTL_DECL(_vfs); SYSCTL_DECL(_net); SYSCTL_DECL(_debug); SYSCTL_DECL(_hw); SYSCTL_DECL(_machdep); SYSCTL_DECL(_user); #ifdef DEBUG /* * CTL_DEBUG variables. * * These are declared as separate variables so that they can be * individually initialized at the location of their associated * variable.
