My question is not clear. Actually ixgbevf driver in my system is kernel module, like this:
[root@yf-mos-corp-host175 ~]# modinfo ixgbevf filename: /lib/modules/3.10.0-514.10.2.el7.mt20170307.x86_64/kernel/drivers/net/ethernet/intel/ixgbevf/ixgbevf.ko version: 2.12.1-k-rh7.3 license: GPL description: Intel(R) 10 Gigabit Virtual Function Network Driver author: Intel Corporation, <linux.n...@intel.com> rhelversion: 7.3 srcversion: C9F11E41E5F60ADED5673E1 alias: pci:v00008086d000015A9sv*sd*bc*sc*i* alias: pci:v00008086d000015A8sv*sd*bc*sc*i* alias: pci:v00008086d00001564sv*sd*bc*sc*i* alias: pci:v00008086d00001565sv*sd*bc*sc*i* alias: pci:v00008086d00001530sv*sd*bc*sc*i* alias: pci:v00008086d00001515sv*sd*bc*sc*i* alias: pci:v00008086d0000152Esv*sd*bc*sc*i* alias: pci:v00008086d000010EDsv*sd*bc*sc*i* depends: intree: Y vermagic: 3.10.0-514.10.2.el7.mt20170307.x86_64 SMP mod_unload modversions signer: CentOS Linux kernel signing key sig_key: 44:C9:F5:E3:67:CB:A0:1D:73:A5:17:C8:70:7B:BA:58:FA:FD:7E:30 sig_hashalgo: sha256 parm: debug:Debug level (0=none,...,16=all) (int) and I use dpdk_nic_bind with --driver option to bind netdevice with ixgbevf kernel driver. So I think I use ixgbevf kernel module which is distributed with kernel, and my kernel is: 3.10.0-514.10.2.el7 2017-09-28 19:54 GMT+08:00 Burakov, Anatoly <anatoly.bura...@intel.com>: > On 28-Sep-17 11:26 AM, Sam wrote: > >> Hi all, >> >> I'm working on ixgbe, I want to enable "PMD_RX_LOG" and "PMD_TX_LOG", how >> to do this? >> >> As for normal application, I could use --log-level param to start, but >> ixgbe is kernel module, how to do this? >> >> Thank you~ >> >> > Hi Sam, > > In DPDK, ixgbe is not a kernel module - these are customized, userspace > drivers.
