How to enable KVM on a higher linux kernel version than 3.x

[Marietto2008]

Hello.

I would like to enable KVM on my old but still functional "Samsung Chromebook ARM model XE303C12 SNOW" because later I want to virtualize FreeBSD with qemu and KVM. To be able to do that,I've opened an issue on this github :

quarkscript/linux-armv7-xe303c12-only#18

a very kind developer told me :

Virtual Open Systems has its own github account. Maybe could be found a commit that switches required registers :

https://github.com/virtualopensystems/u-boot-arndale/commits/lue_arndale-kvm?before=affeaad51746944e8c356091b12ff9c9c6183c4a+35&branch=lue_arndale-kvm&qualified_name=refs%2Fheads%2Flue_arndale-kvm

but it's too technical for me. I would ask you if and how to use your code to enable kvm on a higher kernel version than 3.x. According to :

https://lists.gnu.org/archive/html/qemu-devel/2020-09/msg04932.html

and :

https://www.phoronix.com/news/Linux-5.7-Kill-32-bit-ARM-KVM

for KVM Linux kernel version should be less than 5.7 and qemu version less than 5.

Can someone help me on this ? thanks.
