...ch dependent stuff (the mechanism implementation) is kept in arch/*/kvm folder and with minimal modifications to virt/kvm/* after setting a kconfig variable to enable ROE. But I left room for the user space app using kvm to decide the rightful policy for handling ROE violations. The way it works by KVM_EXIT_MMIO error to user space, keeping all the architectural details hidden away from user space. A last note is that I didn't create this from scratch, instead I extended KVM_MEM_READONLY implementation to also allow R/O per page instead R/O per whole slot which is already done in kernel space.

Hi, This is my first set of patches that works as I would expect, and the third revision I sent to mailing lists. Following up with my previous discussions about kernel rootkit mitigation via placing R/O protection on critical data structure, static data, privileged registers with static content. These patches present the first part where it is only possible to place these protections on memory
