From a8a9d30bab2fae2e0ab3436fa0a40d89fbb0cf4e Mon Sep 17 00:00:00 2001 From: Marcel Apfelbaum Date: Mon, 7 Oct 2013 10:36:34 +0300 Subject: hw/core: Add interface to allocate and free a single IRQ qemu_allocate_irq returns a single qemu_irq. The interface allows to specify an interrupt number. qemu_free_irq frees it. Signed-off-by: Marcel Apfelbaum Signed-off-by: Michael S.
