Add FreeBSD support to OpenZFS

Browse Source 
Add the FreeBSD platform code to the OpenZFS repository.  As of this
commit the source can be compiled and tested on FreeBSD 11 and 12.
Subsequent commits are now required to compile on FreeBSD and Linux.
Additionally, they must pass the ZFS Test Suite on FreeBSD which is
being run by the CI.  As of this commit 1230 tests pass on FreeBSD
and there are no unexpected failures.

* Functions to convert between a list of vdevs and an nvlist representing the
* configuration. Each entry in the list can be one of:
*
* Device vdevs
* disk=(path=..., devid=...)
* file=(path=...)
*
* Group vdevs
* raidz[1|2]=(...)
* mirror=(...)
*
* Hot spares
*
* While the underlying implementation supports it, group vdevs cannot contain
* other group vdevs. All userland verification of devices is contained within
* this file. If successful, the nvlist returned can be passed directly to the
* kernel; we've done as much verification as possible in userland.
*
* Hot spares are a special case, and passed down as an array of disk vdevs, at
* the same level as the root of the vdev tree.
*
* The only function exported by this file is 'make_root_vdev'. The
* function performs several passes:
*
* 1. Construct the vdev specification. Performs syntax validation and
* makes sure each device is valid.
* 2. Check for devices in use. Using libdiskmgt, makes sure that no
* devices are also in use. Some can be overridden using the 'force'
* flag, others cannot.
* 3. Check for replication errors if the 'force' flag is not specified.
* validates that the replication level is consistent across the
* entire pool.
* 4. Call libzfs to label any whole disks with an EFI label.

#ifndef _SYS_ISA_DEFS_H
#define _SYS_ISA_DEFS_H
/*
* This header file serves to group a set of well known defines and to
* set these for each instruction set architecture. These defines may
* be divided into two groups; characteristics of the processor and
* implementation choices for Solaris on a processor.
*
* Processor Characteristics:
*
* _LITTLE_ENDIAN / _BIG_ENDIAN:
* The natural byte order of the processor. A pointer to an int points
* to the least/most significant byte of that int.
*
* _STACK_GROWS_UPWARD / _STACK_GROWS_DOWNWARD:
* The processor specific direction of stack growth. A push onto the
* stack increases/decreases the stack pointer, so it stores data at
* successively higher/lower addresses. (Stackless machines ignored
* without regrets).
*
* _LONG_LONG_HTOL / _LONG_LONG_LTOH:
* A pointer to a long long points to the most/least significant long
* within that long long.
*
* _BIT_FIELDS_HTOL / _BIT_FIELDS_LTOH:
* The C compiler assigns bit fields from the high/low to the low/high end
* of an int (most to least significant vs. least to most significant).
*
* _IEEE_754:
* The processor (or supported implementations of the processor)
* supports the ieee-754 floating point standard. No other floating
* point standards are supported (or significant). Any other supported
* floating point formats are expected to be cased on the ISA processor
* symbol.
*
* _CHAR_IS_UNSIGNED / _CHAR_IS_SIGNED:
* The C Compiler implements objects of type `char' as `unsigned' or
* `signed' respectively. This is really an implementation choice of
* the compiler writer, but it is specified in the ABI and tends to
* be uniform across compilers for an instruction set architecture.
* Hence, it has the properties of a processor characteristic.
*
* _CHAR_ALIGNMENT / _SHORT_ALIGNMENT / _INT_ALIGNMENT / _LONG_ALIGNMENT /
* _LONG_LONG_ALIGNMENT / _DOUBLE_ALIGNMENT / _LONG_DOUBLE_ALIGNMENT /
* _POINTER_ALIGNMENT / _FLOAT_ALIGNMENT:
* The ABI defines alignment requirements of each of the primitive
* object types. Some, if not all, may be hardware requirements as
* well. The values are expressed in "byte-alignment" units.
*
* _MAX_ALIGNMENT:
* The most stringent alignment requirement as specified by the ABI.
* Equal to the maximum of all the above _XXX_ALIGNMENT values.
*
* _ALIGNMENT_REQUIRED:
* True or false (1 or 0) whether or not the hardware requires the ABI
* alignment.
*
* _LONG_LONG_ALIGNMENT_32
* The 32-bit ABI supported by a 64-bit kernel may have different
* alignment requirements for primitive object types. The value of this
* identifier is expressed in "byte-alignment" units.
*
* _HAVE_CPUID_INSN
* This indicates that the architecture supports the 'cpuid'
* instruction as defined by Intel. (Intel allows other vendors
* to extend the instruction for their own purposes.)
*
*
* Implementation Choices:
*
* _ILP32 / _LP64:
* This specifies the compiler data type implementation as specified in
* the relevant ABI. The choice between these is strongly influenced
* by the underlying hardware, but is not absolutely tied to it.
* Currently only two data type models are supported:
*
* _ILP32:
* Int/Long/Pointer are 32 bits. This is the historical UNIX
* and Solaris implementation. Due to its historical standing,
* this is the default case.
*
* _LP64:
* Long/Pointer are 64 bits, Int is 32 bits. This is the chosen
* implementation for 64-bit ABIs such as SPARC V9.
*
* _I32LPx:
* A compilation environment where 'int' is 32-bit, and
* longs and pointers are simply the same size.
*
* In all cases, Char is 8 bits and Short is 16 bits.
*
* _SUNOS_VTOC_8 / _SUNOS_VTOC_16 / _SVR4_VTOC_16:
* This specifies the form of the disk VTOC (or label):
*
* _SUNOS_VTOC_8:
* This is a VTOC form which is upwardly compatible with the
* SunOS 4.x disk label and allows 8 partitions per disk.
*
* _SUNOS_VTOC_16:
* In this format the incore vtoc image matches the ondisk
* version. It allows 16 slices per disk, and is not
* compatible with the SunOS 4.x disk label.
*
* Note that these are not the only two VTOC forms possible and
* additional forms may be added. One possible form would be the
* SVr4 VTOC form. The symbol for that is reserved now, although
* it is not implemented.
*
* _SVR4_VTOC_16:
* This VTOC form is compatible with the System V Release 4
* VTOC (as implemented on the SVr4 Intel and 3b ports) with
* 16 partitions per disk.
*
*
* _DMA_USES_PHYSADDR / _DMA_USES_VIRTADDR
* This describes the type of addresses used by system DMA:
*
* _DMA_USES_PHYSADDR:
* This type of DMA, used in the x86 implementation,
* requires physical addresses for DMA buffers. The 24-bit
* addresses used by some legacy boards is the source of the
* "low-memory" (<16MB) requirement for some devices using DMA.
*
* _DMA_USES_VIRTADDR:
* This method of DMA allows the use of virtual addresses for
* DMA transfers.
*
* _FIRMWARE_NEEDS_FDISK / _NO_FDISK_PRESENT
* This indicates the presence/absence of an fdisk table.
*
* _FIRMWARE_NEEDS_FDISK
* The fdisk table is required by system firmware. If present,
* it allows a disk to be subdivided into multiple fdisk
* partitions, each of which is equivalent to a separate,
* virtual disk. This enables the co-existence of multiple
* operating systems on a shared hard disk.
*
* _NO_FDISK_PRESENT
* If the fdisk table is absent, it is assumed that the entire
* media is allocated for a single operating system.
*
* _HAVE_TEM_FIRMWARE
* Defined if this architecture has the (fallback) option of
* using prom_* calls for doing I/O if a suitable kernel driver
* is not available to do it.
*
* _DONT_USE_1275_GENERIC_NAMES
* Controls whether or not device tree node names should
* comply with the IEEE 1275 "Generic Names" Recommended
* Practice. With _DONT_USE_GENERIC_NAMES, device-specific
* names identifying the particular device will be used.
*
* __i386_COMPAT
* This indicates whether the i386 ABI is supported as a *non-native*
* mode for the platform. When this symbol is defined:
* - 32-bit xstat-style system calls are enabled
* - 32-bit xmknod-style system calls are enabled
* - 32-bit system calls use i386 sizes -and- alignments
*
* Note that this is NOT defined for the i386 native environment!
*
* __x86
* This is ONLY a synonym for defined(__i386) || defined(__amd64)
* which is useful only insofar as these two architectures share
* common attributes. Analogous to __sparc.
*
* _PSM_MODULES
* This indicates whether or not the implementation uses PSM
* modules for processor support, reading /etc/mach from inside
* the kernel to extract a list.
*
* _RTC_CONFIG
* This indicates whether or not the implementation uses /etc/rtc_config
* to configure the real-time clock in the kernel.
*
* _UNIX_KRTLD
* This indicates that the implementation uses a dynamically
* linked unix + krtld to form the core kernel image at boot
* time, or (in the absence of this symbol) a prelinked kernel image.
*
* _OBP
* This indicates the firmware interface is OBP.
*
* _SOFT_HOSTID
* This indicates that the implementation obtains the hostid
* from the file /etc/hostid, rather than from hardware.

* attributes to be requested/returned. File systems may or may not support
* optional attributes. They do so at their own discretion but if they do
* support optional attributes, they must register the VFSFT_XVATTR feature
* so that the optional attributes can be set/retrived.
*
* The fields of the xvattr structure are:
*
* xva_vattr - The first element of an xvattr is a legacy vattr structure
* which includes the common attributes. If AT_XVATTR is set in the va_mask
* then the entire structure is treated as an xvattr. If AT_XVATTR is not
* set, then only the xva_vattr structure can be used.
*
* xva_magic - 0x78766174 (hex for "xvat"). Magic number for verification.
*
* xva_mapsize - Size of requested and returned attribute bitmaps.
*
* xva_rtnattrmapp - Pointer to xva_rtnattrmap[]. We need this since the
* size of the array before it, xva_reqattrmap[], could change which means
* the location of xva_rtnattrmap[] could change. This will allow unbundled
* file systems to find the location of xva_rtnattrmap[] when the sizes change.
*
* xva_reqattrmap[] - Array of requested attributes. Attributes are
* represented by a specific bit in a specific element of the attribute
* map array. Callers set the bits corresponding to the attributes
* that the caller wants to get/set.
*
* xva_rtnattrmap[] - Array of attributes that the file system was able to
* process. Not all file systems support all optional attributes. This map
* informs the caller which attributes the underlying file system was able
* to set/get. (Same structure as the requested attributes array in terms
* of each attribute corresponding to specific bits and array elements.)
*
* xva_xoptattrs - Structure containing values of optional attributes.
* These values are only valid if the corresponding bits in xva_reqattrmap
* are set and the underlying file system supports those attributes.
