Kernel & Driver Data Structures                                     kstat2(9S)



NAME
       kstat2 - Version 2 kernel statistics structure

SYNOPSIS
       #include <sys/types.h>
       #include <sys/kstat2.h>
       #include <sys/ddi.h>
       #include <sys/sunddi.h>

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI)

DESCRIPTION
       Each kernel statistic (kstat2) exported by device drivers consists of a
       header section and a data section. The kstat2 structure is  the  header
       portion of the statistic.


       A  driver  receives a pointer to a kstat2 structure (kstat2_t *) from a
       successful call to kstat2_create(9F). Drivers should never  allocate  a
       kstat2 structure in any other manner.


       After  allocation, the driver should perform any further initialization
       needed before calling kstat2_install(9F) to actually export the kstat.

STRUCTURE MEMBERS
         kstat_t ks1;                    /* v1 kstat(9S) data */

         char ks2_path[KSTAT2_PATHLEN];
                                         /* Unique path to this kstat */

         uint32_t ks2_metatype;          /* Meta-type of this kstat. Reserved for
                                            use by system kstat templates
                                         */

         uint32_t ks2_err;               /* reserved for use by kstat framework
                                         */

         kstat2_md_id_t ks2_md;          /* opaque handle to the metadata for the
                                            values in this kstat
                                         */

         int (*ks2_update)(struct kstat2 *, int);
                                           /* Update function which is used to update the
                                               kstat's data and set the size
                                           */



       Only the ks2_update field may be modified by  the  provider,  and  this
       must   only   be   done   during   the   initialization   time   before
       kstat2_install(9F) is called.


       Other fields in the kstat must be accessed through the macros:


         ks2_kid         /* kstat id */
         ks2_type
         ks2_flags
         ks2_data
         ks2_ndata
         ks2_data_size
         ks2_private     /* for private use by driver */
         ks2_lock



       ks2_kid,  ks2_type,  ks2_flags,  ks2_data,  and  ks2_ndata  should   be
       regarded as read-only once kstat is created.


       ks2_data_size  may  be updated in a custom ks2_update() function, which
       will be called under the kstat's lock (ks2_lock).


       ks2_private allows the driver developer to store a pointer  to  private
       data in the kstat for convenience in processing.


       If  ks2_lock  is  to  be  set,  then this must be done prior to calling
       kstat2_install(9F).
