+ * Tells kstat_create() not to allocate memory for the

+ * 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.

+ * 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.
