Hi Greg, so somehow this discussion stopped without any instructions how to proceed. I think this kind of driver helps every FPGA developer to interface his design via PCIe to a Linux PC. So if there is any chance to get this code merged, I'm glad to rebase this onto the latest kernel release.

Hi Greg, it just uses MSI-X or MSI when available and falls back to legacy IRQ otherwise. Regards, Manuel On Fr, 2017-10-20 at 14:50 +0200, gre...@linuxfoundation.org wrote: > On Fri, Oct 06, 2017 at 07:57:00AM -0700, Stephen Hemminger wrote: > > On Fri, 6 Oct 2017 13:50:44 + > > "Stahl, Man

MSI(X) interrupts are not shared between devices. So when available those should be preferred over legacy interrupts. Signed-off-by: Manuel Stahl ---  drivers/uio/uio_pci_dmem_genirq.c | 27 ---  drivers/uio/uio_pci_generic.c | 24 ++--  2 files chang
