[PATCH v8 03/15] KVM: Introduce __KVM_HAVE_IRQ_LINE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a preparatory patch for the KVM/ARM implementation. KVM/ARM will use
the KVM_IRQ_LINE ioctl, which is currently conditional on
__KVM_HAVE_IOAPIC, but ARM obviously doesn't have any IOAPIC support and we
need a separate define.
