* Filter specific flags for EVFILT_READ
*

*
* The EV_POLL flag indicates the determination should be made via poll(2)
* semantics. These semantics dictate always returning true for regular files,
* regardless of the amount of unread data in the file.
*
* On input, EV_OOBAND specifies that filter should actively return in the
* presence of OOB on the descriptor. It implies that filter will return
* if there is OOB data available to read OR when any other condition
* for the read are met (for example number of bytes regular data becomes >=
* low-watermark).
* If EV_OOBAND is not set on input, it implies that the filter should not actively
* return for out of band data on the descriptor. The filter will then only return
* when some other condition for read is met (ex: when number of regular data bytes
* >=low-watermark OR when socket can't receive more data (SS_CANTRCVMORE)).
*
* On output, EV_OOBAND indicates the presence of OOB data on the descriptor.
* If it was not specified as an input parameter, then the data count is the
* number of bytes before the current OOB marker, else data count is the number
* of bytes beyond OOB marker.

* data/hint fflags for EVFILT_MACHPORT, shared with userspace.

* Only portsets are supported at this time.
*
* The fflags field can optionally contain the MACH_RCV_MSG, MACH_RCV_LARGE,
* and related trailer receive options as defined in <mach/message.h>.
* The presence of these flags directs the kevent64() call to attempt to receive
* the message during kevent delivery, rather than just indicate that a message exists.
* On setup, The ext[0] field contains the receive buffer pointer and ext[1] contains
* the receive buffer length. Upon event delivery, the actual received message size
* is returned in ext[1]. As with mach_msg(), the buffer must be large enough to
* receive the message and the requested (or default) message trailers. In addition,
* the fflags field contains the return code normally returned by mach_msg().
*
* If MACH_RCV_MSG is specified, and the ext[1] field specifies a zero length, the
* system call argument specifying an ouput area (kevent_qos) will be consulted. If
* the system call specified an output data area, the user-space address
* of the received message is carved from that provided output data area (if enough
* space remains there). The address and length of each received message is
* returned in the ext[0] and ext[1] fields (respectively) of the corresponding kevent.
*
* IF_MACH_RCV_VOUCHER_CONTENT is specified, the contents of the message voucher is
* extracted (as specified in the xflags field) and stored in ext[2] up to ext[3]
* length. If the input length is zero, and the system call provided a data area,
* the space for the voucher content is carved from the provided space and its
* address and length is returned in ext[2] and ext[3] respectively.
*
* If no message receipt options were provided in the fflags field on setup, no
* message is received by this call. Instead, on output, the data field simply
* contains the name of the actual port detected with a message waiting.

* 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.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
