From: Sean Christopherson Date: Fri, 2 Aug 2019 22:06:17 +0000 (-0700) Subject: KVM: x86: Unconditionally call x86 ops that are always implemented X-Git-Tag: v5.4-rc1~138^2~27 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=92735b1b3313c97d24b54492a21083c75206e6ed;p=linux.git KVM: x86: Unconditionally call x86 ops that are always implemented Remove a few stale checks for non-NULL ops now that the ops in question are implemented by both VMX and SVM. Note, this is **not** stable material, the Fixes tags are there purely to show when a particular op was first supported by both VMX and SVM. Fixes: 74f169090b6f ("kvm/svm: Setup MCG_CAP on AMD properly") Fixes: b31c114b82b2 ("KVM: X86: Provide a capability to disable PAUSE intercepts") Fixes: 411b44ba80ab ("svm: Implements update_pi_irte hook to setup posted interrupt") Cc: Krish Sadhukhan Signed-off-by: Sean Christopherson Signed-off-by: Paolo Bonzini --- diff --git a/arch/x86/kvm/x86.c b/arch/x86/kvm/x86.c index c4aea2adeaea..cc1e92da8f3c 100644 --- a/arch/x86/kvm/x86.c +++ b/arch/x86/kvm/x86.c @@ -3513,8 +3513,7 @@ static int kvm_vcpu_ioctl_x86_setup_mce(struct kvm_vcpu *vcpu, for (bank = 0; bank < bank_num; bank++) vcpu->arch.mce_banks[bank*4] = ~(u64)0; - if (kvm_x86_ops->setup_mce) - kvm_x86_ops->setup_mce(vcpu); + kvm_x86_ops->setup_mce(vcpu); out: return r; } @@ -9330,10 +9329,7 @@ int kvm_arch_init_vm(struct kvm *kvm, unsigned long type) kvm_page_track_init(kvm); kvm_mmu_init_vm(kvm); - if (kvm_x86_ops->vm_init) - return kvm_x86_ops->vm_init(kvm); - - return 0; + return kvm_x86_ops->vm_init(kvm); } static void kvm_unload_vcpu_mmu(struct kvm_vcpu *vcpu) @@ -10025,7 +10021,7 @@ EXPORT_SYMBOL_GPL(kvm_arch_has_noncoherent_dma); bool kvm_arch_has_irq_bypass(void) { - return kvm_x86_ops->update_pi_irte != NULL; + return true; } int kvm_arch_irq_bypass_add_producer(struct irq_bypass_consumer *cons, @@ -10065,9 +10061,6 @@ void kvm_arch_irq_bypass_del_producer(struct irq_bypass_consumer *cons, int kvm_arch_update_irqfd_routing(struct kvm *kvm, unsigned int host_irq, uint32_t guest_irq, bool set) { - if (!kvm_x86_ops->update_pi_irte) - return -EINVAL; - return kvm_x86_ops->update_pi_irte(kvm, host_irq, guest_irq, set); }
