kstat2(9S) 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_in‐
stall(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 re‐
garded 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).
