Tsirkin" , Alex Williamson Cc: QEMU Developers Hi, First, sorry for such a long time delay on the AER job. I was on 12 days holiday, and start to work on the patch 2 weeks ago, because I use a newer version kernel(4.10 rc8) to start off the work, several tiny problems slow me. Now I meet a confusing issue on aer_inject module. When I use aer_inject command before, it says: Error: Failed to write, No such device then in dmesg, it says: pcieport 0000:00:09.0: aer_inject: AER device not found and then I add some debug line in find_aer_device_iter() to check device->bus-name, find that it is "pci", so that is why I can't inject, it should have been "pci_express". But everything is same as before except a newer host kernel. I still don't have a clue on this problem for almost 2 days, could you help? The topology is my host is: +-09.0-[06]--+-00.0 Intel Corporation 82576 Gigabit Network Connection | \-00.1 Intel Corporation 82576 Gigabit Network Connection -- Sincerely, Cao jin
