This option alone does not add any kernel code. If you say N, all options in this submenu will be skipped and disabled. if VIRTUALIZATION config KVM tristate "Kernel-based Virtual Machine (KVM) support" depends on HAVE_KVM select EXPORT_UASM select PREEMPT_NOTIFIERS select ANON_INODES select KVM_GENERIC_DIRTYLOG_READ_PROTECT select KVM_MMIO select MMU_NOTIFIER select SRCU ---help--- Support for hosting Guest kernels. choice prompt "Virtualization mode" depends on KVM default KVM_MIPS_TE config KVM_MIPS_TE bool "Trap & Emulate" ---help--- Use trap and emulate to virtualize 32-bit guests in user mode. This does not require any special hardware Virtualization support beyond standard MIPS32/64 r2 or later, but it does require the guest kernel to be configured with CONFIG_KVM_GUEST=y so that it resides in the user address segment. config KVM_MIPS_VZ bool "MIPS Virtualization (VZ) ASE" ---help--- Use the MIPS Virtualization (VZ) ASE to virtualize guests. This supports running unmodified guest kernels (with CONFIG_KVM_GUEST=n), but requires hardware support. endchoice config KVM_MIPS_DYN_TRANS bool "KVM/MIPS: Dynamic binary translation to reduce traps" depends on KVM_MIPS_TE default y ---help--- When running in Trap & Emulate mode patch privileged instructions to reduce the number of traps. If unsure, say Y. config KVM_MIPS_DEBUG_COP0_COUNTERS bool "Maintain counters for COP0 accesses" depends on KVM ---help--- Maintain statistics for Guest COP0 accesses. A histogram of COP0 accesses is printed when the VM is shutdown. If unsure, say N. source drivers/vhost/Kconfig endif # VIRTUALIZATION
