Module Name: src
Committed By: mlelstv
Date: Sat May 18 08:38:00 UTC 2019
Modified Files:
src/distrib/sets/lists/comp: mi
src/etc: MAKEDEV.tmpl
src/sys/conf: majors
src/sys/dev: ipmi.c ipmivar.h
src/sys/sys: Makefile
Added Files:
src/sys/sys: ipmi.h
Log Message:
Add experimental userland interface to IPMI driver. Currently, transactions
(like sensor readout) are locked, so that a userland program may interfere with
envsys operation.
To use this you need a program like ipmitool built with OpenIPMI support.
