Protection Keys for Supervisor-mode pages is a simple extension of the PKU feature that QEMU already implements. For supervisor-mode pages, protection key restrictions come from a new MSR. The MSR has no XSAVE state associated to it. PKS is only respected in long mode. However, in principle it is possible to set the MSR even outside long mode, and in fact even the XSAVE state for PKRU could be set outside long mode using XRSTOR. So do not limit the migration subsections for PKRU and PKRS to long mode. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
