[dpdk-users] dpdk hash performance
Hi, I am using rte_hash library with parameters as 2k entries with rte_jhash function with key len as 8 bytes.And key I am using here is just 64 bit unsigned integer . Similarly I am looking on c ++ std:unorder_mapmap with similar entries . I am just doing lookup with 20 keys aginsts 2k entries and the through put performance dip around <=4gbps using rte_hash when compared to std:unorder_map in 100G line .Is there any way to scale the performance using the rte_hash library... with regards, Rahul
[dpdk-users] Interface disappears after binding with DPDK igb_uio
Hello, I am trying to use DPDK on a IXGBE port, but whenever I bind the igb_uio driver to this interface, the interface disappears from the system. DPDK however shows the interface as attached. I also have the KNI module present added to the system, as there are some previous threads that suggested that the interface does not show up because igb_uio driver does not generate netdev devices. Following is the log of the operations: 1. `ifconfig` before binding: enp3s0f0: flags=4099 mtu 1500 ether a0:36:9f:2d:d9:90 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 142934 bytes 63512875 (63.5 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 142934 bytes 63512875 (63.5 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 2. ./dpdk-devbind.py --status-dev net Network devices using kernel driver === :02:00.0 '82576 Gigabit Network Connection 10c9' if=enp2s0f0 drv=igb unused=igb_uio :02:00.1 '82576 Gigabit Network Connection 10c9' if=enp2s0f1 drv=igb unused=igb_uio :03:00.0 'Ethernet Controller 10-Gigabit X540-AT2 1528' if=enp3s0f0 drv=ixgbe unused=igb_uio 3. ./dpdk-devbind.py -b igb_uio :03:00.0 4. ./dpdk-devbind.py --status-dev net Network devices using DPDK-compatible driver :03:00.0 'Ethernet Controller 10-Gigabit X540-AT2 1528' drv=igb_uio unused=ixgbe Network devices using kernel driver === :02:00.0 '82576 Gigabit Network Connection 10c9' if=enp2s0f0 drv=igb unused=igb_uio :02:00.1 '82576 Gigabit Network Connection 10c9' if=enp2s0f1 drv=igb unused=igb_uio 5. `ifconfig` after binding: lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 142934 bytes 63512875 (63.5 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 142934 bytes 63512875 (63.5 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Any help will be greatly appreciated.
[dpdk-users] Error while building DPDK version 19.11 over latest kernel version
Hei, I am trying to build DPDK version 19.11 in my ubuntu machine (18.04) with the latest kernel version 5.9. It gives me an error while I try to build it. The error is when I try to build linux/kni module. The error looks something like this: *dpdk/kernel/linux/kni/kni_dev.h:104:30:* *error: *passing argument 1 of ‘ *get_user_pages_remote*’ from incompatible pointer type [ *-Werror=incompatible-pointer-types*] Is there any workaround?Do I need to disable that module or should I downgrade the kernel version? I wanted to debug my application and see if it needs kni module but I did not not how to disable kni module. I tried common_base and common_linux under config directory but could not find the line which disable this module. Any kind of help will be very much appreciated. Cheers, Klei
