Ideally, you could choose both modes available independently, so that a kernel with both VZ and trap-and-emulate could be built. Can the trap-and-emulate kernels run under VZ? Otherwise, there's hardly any point in having the callbacks in the first place. > int (*vm_init) (struct kvm *kvm); > int (*vcpu_init) (struct kvm_vcpu *vcpu); > int (*vcpu_setup) (struct kvm_vcpu *vcpu); > @@ -517,23 +645,26 @@ uint32_t kvm_get_user_asid(struct kvm_vcpu *vcpu); > > uint32_t kvm_get_commpage_asid (struct kvm_vcpu *vcpu); > > -extern int kvm_mips_handle_kseg0_tlb_fault(unsigned long badbaddr, > +#ifdef CONFIG_KVM_MIPS_VZ > +extern int kvm_mips_handle_vz_root_tlb_fault(ulong badvaddr, > + struct kvm_vcpu *vcpu); > +#endif kvm_tlb.c has many parts that, after this patch, are BUG_ON(!cpu_has_vz)'d. Perhaps you could split it into kvm_tlb.c, kvm_tlb_emul.c, kvm_tlb_vz.c? Then these functions can also be in a separate header, rather than being #ifdef'ed in this one. This raises a related question: how much of kvm_mips_emul.c is reused under VZ? In x86, you can trigger emulation of any instruction by "racing" the emulator: one VCPU triggers emulation of an instruction that has to be emulated, the second rewrites it to another one on the fly. Another way to do the same is to make the iTLB and dTLB point to different pages (load from the address of the instruction, change the page table, execute the instruction; then the emulator will use the entry from the dTLB). Would it be possible to "trick" KVM into executing unwanted branches of kvm_mips_emul.c by these tricks? If so, the best thing would be to just reenter the guest and retry executing the same instruction. But a BUG_ON() is definitely wrong, because it will crash the host.
