It is now linked into the EL2 NVHE code which means there are constraints on what can be used from there -- you'll need a bit of extra work to make some of these functions available to EL2.
I see, thanks for reminding me this. I will work on kvmarm/next and send a new version later. Thanks, Yanan
Thanks, Quentin .
