|
|
* levels defined below it, or it is a leaf of some particular
|
|
* type given below. Each sysctl level defines a set of name/type
|
|
* pairs to be used by sysctl(1) in manipulating the subsystem.
|
|
*
|
|
* When declaring new sysctl names, use the CTLFLAG_LOCKED flag in the
|
|
* type to indicate that all necessary locking will be handled
|
|
* within the sysctl.
|
|
*
|
|
* Any sysctl defined without CTLFLAG_LOCKED is considered legacy
|
|
* and will be protected by a global mutex.
|
|
*
|
|
* Note: This is not optimal, so it is best to handle locking
|
|
* yourself, if you are able to do so. A simple design
|
|
* pattern for use to avoid in a single function known
|
|
* to potentially be in the paging path ot doing a DMA
|
|
* to physical memory in a user space process is:
|
|
*
|
|
* lock
|
|
* perform operation vs. local buffer
|
|
* unlock
|
|
* SYSCTL_OUT(rey, local buffer, length)
|
|
*
|
|
* ...this assumes you are not using a deep call graph
|
|
* or are unable to pass a local buffer address as a
|
|
* parameter into your deep call graph.
|
|
*
|
|
* Note that very large user buffers can fail the wire
|
|
* if to do so would require more physical pages than
|
|
* are available (the caller will get an ENOMEM error,
|
|
* see sysctl_mem_hold() for details).

/*
|
|
* 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.nperflevels - Number of core types in the system. See the parameters below, which can be used to get
|
|
* - information associated with a specific perf level.
|
|
*
|
|
* The following parameters apply to perflevel N, where N is a number between 0 and the number of core types in the system minus one.
|
|
* perflevel 0 always refers to the highest performance core type in the system.
|
|
*
|
|
* hw.perflevelN.physicalcpu - The number of physical processors available in the current power management mode.
|
|
* hw.perflevelN.physicalcpumax - The maximum number of physical processors that could be available this boot.
|
|
* hw.perflevelN.logicalcpu - The number of logical processors available in the current power management mode.
|
|
* hw.perflevelN.logicalcpumax - The maximum number of logical processors that could be available this boot.
|
|
*
|
|
* hw.perflevelN.l1dcachesize - These values provide the size in bytes of the L1, L2 and L3 caches. If a cache is not present
|
|
* hw.perflevelN.l1icachesize - then the selector will return and error.
|
|
* hw.perflevelN.l2cachesize -
|
|
* hw.perflevelN.l3cachesize -
|
|
*
|
|
* hw.perflevelN.cpusperl2 - These values provide the number of CPUs of the same type that share L2 and L3 caches.
|
|
* hw.perflevelN.cpusperl3 - If a cache is not present then the selector will return and error.
|
|
*
|
|
* hw.perflevelN.l2perflevels - These values provide a bitmap, where bit number of CPUs of the same type that share L2 and L3 caches.
|
|
* hw.perflevelN.l3perflevels - If a cache is not present then the selector will return and error.
|
|
*
|
|
* 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
|
|
