I think this patch can't solve the problem correctly but I haven't figured out the reason. I am so sorry about it. It's okay. But you should reply earlier here, so that I would not apply it. Regarding the crash, I believe Jianfeng had met a similar issue before. IIRC, it's about the order of event fd setups (or something like it). You might want to contact him for more details. And it's dropped. --yliu > > -----Original Message----- > > From: Yuanhan Liu [mailto:yliu@fridaylinux.org] > > Sent: Monday, July 31, 2017 10:30 > > To: Hu, Jiayu > > Cc: dev@dpdk.org; Tan, Jianfeng ; Yao, Lei A > > ; stable@dpdk.org > > Subject: Re: [PATCH] net/virtio: fix fail to configure rxq interrupt > > > > On Wed, Jul 19, 2017 at 11:18:23AM +0800, Jiayu Hu wrote: > > > When use rte_eth_dev_configure() to enable rx queue interrupt for virtio > > > devices, virtio_configure_intr() isn't called to set up the interrupt > > > environment, which causes rx queue interrupt setup failed.
