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
