We have apm(4), that uses pmf(9), and apmdev(4), that uses
dopowerhooks(9). They are mostly identical otherwise. My
understanding is that powerhooks API is being deprecated. The only
two remaining users are apmdev(4) used by zaurus all hpc* ports and
arch/arm/xscale/pxa2x0_apm.c that doesn't seem to be mentioned in any
I want to have zaurus and hpc* ports switched to apm(4) so that we can
retire apmdev(4) and powerhooks API.
I brought over changes from apm to apmdev so that now they only differ
in pmf vs powerhooks bits and in trivial s/apm/apmdev/ naming diffs.
Now that they are demonstrably congruent we can do the switch knowing
that effectively we only change power management hooks.
After my recent commits you can just replace "apmdev0 at hpcapm0" with
"apm0 at hpcapm0" in your kernel config to give it a try. My Jornada
Devices without power management support: mainbus0 cpu0 btnmgr0 shb0

but seems to suspend and resume fine otherwise.
We need to properly convert all drivers to pmf. For most of them a
no-op hook is probably sufficient for now as hpcapm(4) uses its own
config_hook(9) hooks to manage power.
So if you can help with this task it would be greatly appreciated. I
can do hpcsh, but I have no other hpc machines.
Thanks in advance.
