It's not always necessary to modify uio_dmem_genirq.<br>
<br>
Certainly in cases where the hardware capability can be specified by
a device tree (e.g. ARM systems), it is possible to specify an
address space and an IRQ that can be immediately used from userspace
with the uio_dmem_genirq driver with no modifications.<br>
