Absolute homing

I'm looking for a reliable and safe solution to manage homing with absolute encoders. The machine has to be homed once and reminds the home position even after power off and mechanical movents in powered off state. So clearly, I dont have to home on every power cycle. 
My homing is done in the servo drive itself and passes the data to linuxcnc. 

What I looking for is something like that:
- I would like to disable the hole homing process from HAL, and on power on, shows me the machine is already homed, all axis turn green. 

What is the best method to manage absolute homing anyway?

Thanks. 
 

What pin do the drives use to let LinuxCNC know they are homed?
Probably connecting the all-homed pin to and3 out (i think such module exists in LinuxCNC) and drive pins to inputs should work.
Or maybe using the lut5 component if there are more than 3 drives...

I'm using

cia402.0.home

to start the homing process on drives,

then

cia402.0.stat-homing

drives responds they are homing,

cia402.0.stat-homed

after they homed.

here is the process in hal:
# homing
net x-home-request joint.0.request-custom-homing => cia402.0.home
net x-homing joint.0.is-custom-homing <= cia402.0.stat-homing
net x-homed joint.0.custom-homing-finished <= cia402.0.stat-homed

I have to home 4 drives, later 5.

Yes, there is motion.is-all-homed pin, but is not writable.

Tried with setp motion.is-all-homed true

Unfortunately, with the standard homing module there is no way to tell the controller that an axis has been homed using a HAL pin.
Have you looked at using HOME_ABSOLUTE_ENCODER setting in the ini file?

Also it is possible to have a custom homing procedure:
www.linuxcnc.org/docs/html/man/man9/homecomp.9.html

Right now I'm using these two methods for homing. I have a custom homing process, compiled with homecomp and activates the internal homing of the drives. When the homing is done, I turn off (comment out) from the hal and ini and using just HOME_ABSOLUTE_ENCODER = 2, so no movement on axis.
But still have to solve the jogging problem, becouse before axes are homed, sill allowed to jog the machine out of softlimits. Unfortunately the soflimist are not working while unhomed.

This method is not so comfortable, but working. I'm still looking for better homing solution.
