Hello, I would please like to ask about uio_generic_pci :
1. how to set irq from userspace. Is there anything similar to echo "3" > /sys/bus/pci/drivers/uio_pci_generic/irq in all documentation which talk about it, it is not mentioned (or I don't find it): https://github.com/rumpkernel/wiki/wiki/Howto:-Accessing-PCI-devices-from-userspace http://www.hep.by/gnu/kernel/uio-howto/uio_pci_generic.html 2. Is there a way to use dma from userspace with this driver ? Best Regards, Ran
