I want to create one sysctl node for each CPU in the system. This information is available only at runtime. -Arun State Changed From-To: open->closed Dynamic sysctl's have been implemented. |
A patch to create dynamic sysctl nodes at runtime Fix: The following code (and corresponding code for other data types supported by sysctl) needs to go into /usr/src/sys/kern/kern_sysctl.c void sysctl_register_long(struct sysctl_oid_list *parent, int number, char *name, int access, long *ptr, struct sysctl_oid *oidp) { oidp->oid_parent = parent; SLIST_NEXT(oidp, oid_link) = NULL; oidp->oid_number = number; oidp->oid_name = name; oidp->oid_handler = sysctl_handle_long; oidp->oid_kind = CTLTYPE_INT | access; oidp->oid_arg1 = (void *) ptr; oidp->oid_arg2 = 0; oidp->oid_fmt = "L"; /* Register this oid */ sysctl_register_oid(oidp); } How-To-Repeat: N/A
