From 43771ebfc9d34ab1f74095d052d225a82ae0898c Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Wed, 14 Dec 2011 12:27:47 +0200 Subject: [PATCH] KVM: Make KVM_INTEL depend on CPU_SUP_INTEL PMU virtualization needs to talk to Intel-specific bits of perf; these are only available when CPU_SUP_INTEL=y. Fixes arch/x86/built-in.o: In function `atomic_switch_perf_msrs': vmx.c:(.text+0x6b1d4): undefined reference to `perf_guest_get_msrs' Reported-by: Ingo Molnar Reported-by: Randy Dunlap Signed-off-by: Avi Kivity Signed-off-by: Marcelo Tosatti --- arch/x86/kvm/Kconfig | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/x86/kvm/Kconfig b/arch/x86/kvm/Kconfig index ff5790d8e990..ca4d49ed9a6c 100644 --- a/arch/x86/kvm/Kconfig +++ b/arch/x86/kvm/Kconfig @@ -52,6 +52,8 @@ config KVM config KVM_INTEL tristate "KVM for Intel processors support" depends on KVM + # for perf_guest_get_msrs(): + depends on CPU_SUP_INTEL ---help--- Provides support for KVM on Intel processors equipped with the VT extensions.
