config PPC_RTAS
bool "Support for RTAS (RunTime Abstraction Services) in /proc"
depends on PPC_OF && PROC_FS
---help---
When you use this option, you will be able to use RTAS from
userspace.
RTAS stands for RunTime Abstraction Services and should
provide a portable way to access and set system information. This is
commonly used on RS/6000 (pSeries) computers.
You can access RTAS via the special proc file system entry rtas.
Don't confuse this rtas entry with the one in /proc/device-tree/rtas
which is readonly.
If you don't know if you can use RTAS look into
/proc/device-tree/rtas. If there are some entries, it is very likely
that you will be able to use RTAS.
You can do cool things with rtas. To print out information about
various sensors in the system, just do a
$ cat /proc/rtas/sensors
or if you power off your machine at night but want it running when
you enter your office at 7:45 am, do a
# date -d 'tomorrow 7:30' +%s > /proc/rtas/poweron
and shutdown.
If unsure, say Y.
