Well, I can't quite make it work with a kern.* sysctl subtree.. It's obvious
that this has something to do with SYSCTL_DECL(), but - how? :)
I currently have these in my warp_saver.c (just kern.saver for simplicity):
SYSCTL_DECL(_kern_saver);
SYSCTL_INT(_kern_saver, OID_AUTO, dir, CTLFLAG_RW, &warp_dir, 0, "")
SYSCTL_INT(_kern_saver, OID_AUTO, step, CTLFLAG_RW, &warp_step, 0, "")
SYSCTL_INT(_kern_saver, OID_AUTO, period, CTLFLAG_RW, &warp_period, 0, "")
It builds and installs fine, and then:
[root@ringworld:v0 /usr/mysrc/sys/modules/syscons/warp]# make load
/sbin/kldload -v ./warp_saver.ko
link_elf: symbol sysctl__kern_saver_children undefined
kldload: can't load ./warp_saver.ko: Exec format error
*** Error code 1
Stop in /usr/mysrcx/sys/modules/syscons/warp.
[root@ringworld:v0 /usr/mysrc/sys/modules/syscons/warp]#
Apparently I'm missing something.. <whine> Help? </whine>
G'luck,
Peter
