FYI.
When examining the ancient simos-ppc, which was specifically made to boot and run a modified AIX 4.3.3 kernel/system, they implemented the following RTAS-functions:
assume-power-management,
cache-control,
check-exception,
display-character,
event-scan,
exti2c,
freeze-time-base,
get-power-level,
get-sensor-state,
get-time-of-day,
hibernate,
last-error,
nvram-fetch,
nvram-store,
os-term,
power-off,
query-cpu-stopped-state,
read-pci-config,
reboot,
refresh-firmware-parameters,
relinquish-power-management,
restart-rtas,
set-indicator,
set-power-level,
set-time-for-power-on,
set-time-of-day,
start-cpu,
stop-self,
suspend
thaw-time-base,
update-flash,
write-pci-config
Most of the functions only returns "success" or "hardware failure".
