Greetings,
I'm developing a product based on KVM/ARM, in which i need to modify the code that is responsible for entering
into guest mode(i.e. EL1?) and i don't really want to recompile the kernel and flash it again as part of my development. I need to run
on baremetal(on the board itself) when testing my code.
Any plans for supporting this in the near future? or any other suggestions on a less painful development process?
Thanks,
Mike.

Not today. KVM has to map its code to run in a different CPU mode, the code that
does this assumes its physically contiguous and part of the kernel text.

No, because its not supported. On arm/arm64 KVM is either built as part of the
kernel, or not.
Why do you need KVM as a loadable module?
Thanks,
James
