Hi,
I have an application over dpdk which is consisted of the following threads
each running on a separate core:
1) rx thread which listens on in a poll mode for traffic
2) 2 packet processing threads (for load balancing)
3) kni thread (which also runs on a separate core).
the rx thread receives p

Hi,
When calling tcpreplay for any device and not necessarily the kni it can
take a few minutes until the packet transmission starts. this occurs only
when the kni_thread is running.
I am running on Centos with kernel version 3.10 and libpcap version 1.5.3
I tried debugging the tcpreplay and notice
Hi,
We are trying to run a dpdk based application one the same machine with
other java based applications.
In order to do that we isolated the dpdk application cores and disabled
hyperthreading for those cores.
But sporadically we encounter misses over the interface.
We are running on a single sock

Hi Rami,
This is the printout for cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.15.0-43-generic
root=UUID=6f1a210b-a30f-456d-bf16-bbb210da5666 ro default_hugepagesz=2M
hugepagesz=2M hugepages=4096 isolcpus=1-5 nohz_full=1-5 rcu_nocbs=1-5
The requires cpus are in fact isolated but jvm generate some
can be solved.

Hi Rami,
This is correct but that is because the default value of the PF_NO_SETAFFINITY
flags does not allow to set affinity to kernel threads from user space.
I was looking for a way to change the kernel and recompile it to be able to
block kernel threads from running on the cpu isolated cores. (s
Perhaps by modifying the function set_cpus_allowed() which sets the kernel
threads flag with PF_NO_SETAFFINITY.
To remark it in the kernel code and to recompile the code.

Hi,
I will consider that.
Thanks again for your help.

Hi,
I am running an application over dpdk ver 16.04.
My application massively inserting and deleting from a hash table using a
key that can be very similar for many instances.
I noticed that in some cases I am unable to find an entry while I am
certain it was inserted successfully.
I wrote a test

Hi,
We are using KVM for loading our VM using e1000 driver for the VM interface.
we noticed that the maximum rate (rx/tx) I get is 10Mbps.
I am currently attempting to move to virtio driver using dpdk release 2.0.
