[PATCH 0/3] i386/kvm: Assume IRQ routing is always available

Posted by Eduardo Habkost 3 years, 7 months ago

KVM_CAP_IRQ_ROUTING is available since 2019 (Linux v2.6.30), so
we can safely assume it's always present and remove some runtime
checks.

Eduardo Habkost (3):
  i386/kvm: Require KVM_CAP_IRQ_ROUTING
  i386/kvm: Remove IRQ routing support checks
  i386/kvm: Delete kvm_allows_irq0_override()
