[vpp-dev] efficient use of DPDK

2019-12-02 Thread Thomas Monjalon
Hi all, VPP has a buffer called vlib_buffer_t, while DPDK has rte_mbuf. Are there some benchmarks about the cost of converting, from one format to the other one, during Rx/Tx operations? I'm sure there would be some benefits of switching VPP to natively use the DPDK mbuf allocated in mempools. Wh

Hi Yang.L, I just tried out nginx + debug vcl and ldp + debug vpp. Everything seems to be working fine. Once you start nginx, do you get any errors in /var/log/syslog. What does “show sessions verbose” return? There might be some issues with your config. Thanks, Florin > On Dec 2, 2019, at

Hi Paul, Are you thinking about using tcp to generate packets? If yes, probably you want to take a look at the iperf vcl tests (test/test_vcl.py). Regards, Florin > On Dec 2, 2019, at 9:57 AM, Paul Vinciguerra > wrote: > > There was a brief discussion on the community call about using hosts

[vpp-dev] Using hoststack instead of tap

2019-12-02 Thread Paul Vinciguerra
There was a brief discussion on the community call about using hoststack as an alternative to running tests as a privileged user for a tap interface. Is there any documentation on this, or is there a representative test case I can reference? -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages s

Paul, The VPP continuous integration system utilizes code primarily from the following three repos: https://git.fd.io/ci-management/  (Note: this uses git submodule for global-jjb) https://git.fd.io/csit/ https://git.fd.io/vpp/ Changes to any of these can cause "the wheels to fall off the b

How can we make this process more transparent? I saw this issue on Friday. I searched all the repo's for recently merged changes, but found nothing. Is there somewhere else to look that I'm not aware of? On Mon, Dec 2, 2019 at 8:25 AM Jerome Tollet via Lists.Fd.Io wrote: > Hi Dave, > > I ju

You are right, The clib_mem_init call mmap to allocate virtual memory, but I got random SIGSEGV for the client program When the running machine has low memory ( about 2G ). So I changed client.c and memory_client.c to allocate lower virtual memory and only when I call connect_to_vlib. The changes
