This patch set if my first attempt to make virtio_console usable on s390. To do so, I had to change hvc_console, because s390 has no request_irq and no free_irq. I want to get feedback from the main users of hvc_console before I proceed. The basic idea of this patch set is to remove the calls to request_irq and free_irq and replace them with backend specific callbacks. Please see the descriptions of the patches for further details: 1/3: hvc_console: rework setup to replace irq functions with callbacks 2/3: virtio_console: use virtqueue notification for hvc_console 3/3: s390: use virtio_console for KVM on s390 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/virtualization
