Enable tso in VM #11

So, I have one more question...
Is it possible to enable tso in a virtual machine with Linux? Recently I found this tweet but it seems that author hasn't found any solution since that time.
I tried to load this kernel module inside a VM but this module doesn't work properly. I can only read actlr_el1 register by read_sysreg but I can't write a new value. When I try to update it's value register remains unchanged. Do you have any suggestions why does this happen?

Is there anything new?

I think I heard something about this being moved behind an entitlement, I'll have to look into it more.
