We don't want to expose complicated features to guests until we have a good grasp on the basic CPU emulation. So let's pretend that RAS, doesn't exist in a nested guest. We already hide the feature bits, let's now make sure VDISR_EL1 will UNDEF. Signed-off-by: Marc Zyngier <maz@kernel.org> --- arch/arm64/kvm/sys_regs.c | 1 + 1 file changed, 1 insertion(+)
