* example, if sep is '.', name might look like: "a" or "a.b" or "a.c[3]" or
* "a.d[3].e[1]". This matches the C syntax for array embed (for convience,
* code also supports "a.d[3]e[1]" syntax).
*
* If 'ip' is non-NULL and the last name component is an array, return the
* value of the "...[index]" array index in *ip. For an array reference that
* is not indexed, *ip will be returned as -1. If there is a syntax error in

#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.

* kstat structure and locking strategy

* kstat_chain_lock protects all additions to/deletions from this set,
* as well as all changes to kstat headers. kstat data sections are
* *optionally* protected by the per-kstat ks_lock. If ks_lock is non-NULL,
* kstat clients (e.g. /dev/kstat) will acquire this lock for all of their
* operations on that kstat. It is up to the kstat provider to decide whether
* guaranteeing consistent data to kstat clients is sufficiently important
* to justify the locking cost. Note, however, that most statistic updates
* already occur under one of the provider's mutexes, so if the provider sets
* ks_lock to point to that mutex, then kstat data locking is free.
*
* NOTE: variable-size kstats MUST employ kstat data locking, to prevent
* data-size races with kstat clients.
*

* kstat data section; instead, you will set the ks_data
* field to point to the data you wish to export. This
* provides a convenient way to export existing data
* structures.
*
* KSTAT_FLAG_VAR_SIZE:
*
* The size of the kstat you are creating will vary over time.
* For example, you may want to use the kstat mechanism to
* export a linked list. NOTE: The kstat framework does not
* manage the data section, so all variable-size kstats must be
* virtual kstats. Moreover, variable-size kstats MUST employ
* kstat data locking to prevent data-size races with kstat
* clients. See the section on "kstat snapshot" for details.
*
* KSTAT_FLAG_WRITABLE:
*
* Makes the kstat's data section writable by root.
* The ks_snapshot routine (see below) does not need to check for
* this; permission checking is handled in the kstat driver.
*
* KSTAT_FLAG_PERSISTENT:
*
* Indicates that this kstat is to be persistent over time.
* For persistent kstats, kstat_delete() simply marks the
* kstat as dormant; a subsequent kstat_create() reactivates
* the kstat. This feature is provided so that statistics
* are not lost across driver close/open (e.g., raw disk I/O
* on a disk with no mounted partitions.)
* NOTE: Persistent kstats cannot be virtual, since ks_data
* points to garbage as soon as the driver goes away.
*
* The following flags are maintained by the kstat framework:
*
* KSTAT_FLAG_DORMANT:
*
* For persistent kstats, indicates that the kstat is in the
* dormant state (e.g., the corresponding device is closed).
*
* KSTAT_FLAG_INVALID:
*
* This flag is set when a kstat is in a transitional state,
* e.g. between kstat_create() and kstat_install().
* kstat clients must not attempt to access the kstat's data
* if this flag is set.

/*
* Dynamic update support
*
* The kstat mechanism allows for an optional ks_update function to update
* kstat data. This is useful for drivers where the underlying device
* keeps cheap hardware stats, but extraction is expensive. Instead of
* constantly keeping the kstat data section up to date, you can supply a
* ks_update function which updates the kstat's data section on demand.
* To take advantage of this feature, simply set the ks_update field before
* calling kstat_install().
*
* The ks_update function, if supplied, must have the following structure:
*
* int
* foo_kstat_update(kstat_t *ksp, int rw)
* {
* if (rw == KSTAT_WRITE) {
* ... update the native stats from ksp->ks_data;
* return EACCES if you don't support this
* } else {
* ... update ksp->ks_data from the native stats
* }
* }
*
* The ks_update return codes are: 0 for success, EACCES if you don't allow
* KSTAT_WRITE, and EIO for any other type of error.
*
* In general, the ks_update function may need to refer to provider-private
* data; for example, it may need a pointer to the provider's raw statistics.
* The ks_private field is available for this purpose. Its use is entirely
* at the provider's discretion.
*
* All variable-size kstats MUST supply a ks_update routine, which computes
* and sets ks_data_size (and ks_ndata if that is meaningful), since these
* are needed to perform kstat snapshots (see below).
*
* No kstat locking should be done inside the ks_update routine. The caller
* will already be holding the kstat's ks_lock (to ensure consistent data).

/*
* Kstat snapshot
*
* In order to get a consistent view of a kstat's data, clients must obey
* the kstat's locking strategy. However, these clients may need to perform
* operations on the data which could cause a fault (e.g. copyout()), or
* operations which are simply expensive. Doing so could cause deadlock
* (e.g. if you're holding a disk's kstat lock which is ultimately required
* to resolve a copyout() fault), performance degradation (since the providers'
* activity is serialized at the kstat lock), device timing problems, etc.
*
* To avoid these problems, kstat data is provided via snapshots. Taking
* a snapshot is a simple process: allocate a wired-down kernel buffer,
* acquire the kstat's data lock, copy the data into the buffer ("take the
* snapshot"), and release the lock. This ensures that the kstat's data lock
* will be held as briefly as possible, and that no faults will occur while
* the lock is held.
*
* Normally, the snapshot is taken by default_kstat_snapshot(), which
* timestamps the data (sets ks_snaptime), copies it, and does a little
* massaging to deal with incomplete transactions on i/o kstats. However,
* this routine only works for kstats with contiguous data (the typical case).
* If you create a kstat whose data is, say, a linked list, you must provide
* your own ks_snapshot routine. The routine you supply must have the
* following prototype (replace "foo" with something appropriate):
*
* int foo_kstat_snapshot(kstat_t *ksp, void *buf, int rw);
*
* The minimal snapshot routine -- one which copies contiguous data that
* doesn't need any massaging -- would be this:
*
* ksp->ks_snaptime = gethrtime();
* if (rw == KSTAT_WRITE)
* bcopy(buf, ksp->ks_data, ksp->ks_data_size);
* else
* bcopy(ksp->ks_data, buf, ksp->ks_data_size);
* return (0);
*
* A more illuminating example is taking a snapshot of a linked list:
*
* ksp->ks_snaptime = gethrtime();
* if (rw == KSTAT_WRITE)
* return (EACCES); ... See below ...
* for (foo = first_foo; foo; foo = foo->next) {
* bcopy((char *) foo, (char *) buf, sizeof (struct foo));
* buf = ((struct foo *) buf) + 1;
* }
* return (0);
*
* In the example above, we have decided that we don't want to allow
* KSTAT_WRITE access, so we return EACCES if this is attempted.
*
* The key points are:
*
* (1) ks_snaptime must be set (via gethrtime()) to timestamp the data.
* (2) Data gets copied from the kstat to the buffer on KSTAT_READ,
* and from the buffer to the kstat on KSTAT_WRITE.
* (3) ks_snapshot return values are: 0 for success, EACCES if you
* don't allow KSTAT_WRITE, and EIO for any other type of error.
*
* Named kstats (see section on "Named statistics" below) containing long
* strings (KSTAT_DATA_STRING) need special handling. The kstat driver
* assumes that all strings are copied into the buffer after the array of
* named kstats, and the pointers (KSTAT_NAMED_STR_PTR()) are updated to point
* into the copy within the buffer. The default snapshot routine does this,
* but overriding routines should contain at least the following:
*
* if (rw == KSTAT_READ) {
* kstat_named_t *knp = buf;
* char *end = knp + ksp->ks_ndata;
* uint_t i;
*
* ... Do the regular copy ...
* bcopy(ksp->ks_data, buf, sizeof (kstat_named_t) * ksp->ks_ndata);
*
* for (i = 0; i < ksp->ks_ndata; i++, knp++) {
* if (knp[i].data_type == KSTAT_DATA_STRING &&
* KSTAT_NAMED_STR_PTR(knp) != NULL) {
* bcopy(KSTAT_NAMED_STR_PTR(knp), end,
* KSTAT_NAMED_STR_BUFLEN(knp));
* KSTAT_NAMED_STR_PTR(knp) = end;
* end += KSTAT_NAMED_STR_BUFLEN(knp);
* }
* }

* Adding and deleting kstats.
*
* The typical sequence to add a kstat is:
*
* ksp = kstat_create(module, instance, name, class, type, ndata, flags);
* if (ksp) {
* ... provider initialization, if necessary
* kstat_install(ksp);
* }
*
* There are three logically distinct steps here:
*
* Step 1: System Initialization (kstat_create)
*
* kstat_create() performs system initialization. kstat_create()
* allocates memory for the entire kstat (header plus data), initializes
* all header fields, initializes the data section to all zeroes, assigns
* a unique KID, and puts the kstat onto the system's kstat chain.
* The returned kstat is marked invalid (KSTAT_FLAG_INVALID is set),
* because the provider (caller) has not yet had a chance to initialize
* the data section.
*
* By default, kstats are exported to all zones on the system. A kstat may be
* created via kstat_create_zone() to specify a zone to which the statistics
* should be exported. kstat_zone_add() may be used to specify additional
* zones to which the statistics are to be exported.
*
* Step 2: Provider Initialization
*
* The provider performs any necessary initialization of the data section,
* e.g. setting the name fields in a KSTAT_TYPE_NAMED. Virtual kstats set
* the ks_data field at this time. The provider may also set the ks_update,
* ks_snapshot, ks_private, and ks_lock fields if necessary.
*
* Step 3: Installation (kstat_install)
*
* Once the kstat is completely initialized, kstat_install() clears the
* INVALID flag, thus making the kstat accessible to the outside world.
* kstat_install() also clears the DORMANT flag for persistent kstats.
*
* Removing a kstat from the system
*
* kstat_delete(ksp) removes ksp from the kstat chain and frees all
* associated system resources. NOTE: When you call kstat_delete(),
* you must NOT be holding that kstat's ks_lock. Otherwise, you may
* deadlock with a kstat reader.
*
* Persistent kstats
*
* From the provider's point of view, persistence is transparent. The only
* difference between ephemeral (normal) kstats and persistent kstats
* is that you pass KSTAT_FLAG_PERSISTENT to kstat_create(). Magically,
* this has the effect of making your data visible even when you're
* not home. Persistence is important to tools like iostat, which want
* to get a meaningful picture of disk activity. Without persistence,
* raw disk i/o statistics could never accumulate: they would come and
* go with each open/close of the raw device.
*
* The magic of persistence works by slightly altering the behavior of
* kstat_create() and kstat_delete(). The first call to kstat_create()
* creates a new kstat, as usual. However, kstat_delete() does not
* actually delete the kstat: it performs one final update of the data
* (i.e., calls the ks_update routine), marks the kstat as dormant, and
* sets the ks_lock, ks_update, ks_private, and ks_snapshot fields back
* to their default values (since they might otherwise point to garbage,
* e.g. if the provider is going away). kstat clients can still access
* the dormant kstat just like a live kstat; they just continue to see
* the final data values as long as the kstat remains dormant.
* All subsequent kstat_create() calls simply find the already-existing,
* dormant kstat and return a pointer to it, without altering any fields.
* The provider then performs its usual initialization sequence, and
* calls kstat_install(). kstat_install() uses the old data values to
* initialize the native data (i.e., ks_update is called with KSTAT_WRITE),
* thus making it seem like you were never gone.
