Can I enable it somehow maybe by using a module option?
No module parameter for that, you'd have to hack the code in ahci.c to
force the option on. No guarantees it's going to work if the
controller doesn't report the capability, though.
Could you please give me a hint what to change in ahci.c?
I would like to try and see what happens.
Based on the version in Linus' git, you'd likely want to add to
ahci_save_initial_config something like:
cap |= HOST_CAP_PMP;
Could such a hack damage the hardware?
Not likely. It's not impossible that data loss could result though,
better back up important files first..
