Re: [vpp-dev] [vppsb-dev] vpp router plugin threads? (vpp + router + netlink + FRRouting)

Hello Brian, If you believe that some process interferes with your worker threads, try and isolates some CPUs from the kernel scheduler (isolcpus on linux kernel), and set the CPU affinity from /etc/vpp/startup.conf (corelist-workers & main-core). Korian On 12/12/18 4:17 AM, Brian Dickson

I am not sure on the reason for this, but it is documented here: https://github.com/contiv/vpp/blob/master/docs/arm64/MANUAL_INSTALL_CAVIUM.md “To mention the most important thing from DPDK setup instructions you need to setup 1GB hugepages. The allocation of hugepages should be done at boot

W...What??? So the only way to make ip reassembly working correctly is to keep one or more interfaces attached to a single worker thread? That does not sound efficient .. mik...@yeah.net From: Klement Sekera Date: 2018-12-11 20:39 To: Mikado; vpp-dev Subject: Re: [vpp-dev] Any tricks in

Hi Klement. Is there a way to write a test case that documents that behavior?  Does the test framework have the ability to split fragments across threads? -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. View/Reply Online (#11583):

Re: [vpp-dev] vppinfra vec alignment

That should be corrected to: Users may specify the alignment for first data element via the vec*_aligned macros. Other elementa will be alligned only is data structure is alligned, i.e. By CLIB_CACHELINE_ALIGN_MARK(...) macro... — Damjan > On Dec 12, 2018, at 2:04 PM, Mohammed Alshohayeb

Re: [vpp-dev] vpp router plugin threads? (vpp + router + netlink + FRRouting)

FYI: I have tried to build these in the last couple of days. The current "version" of vppsb/netlink and vppsb/router seem to not compile with any version. I'm not sure who is maintaining the code or updating the repo, but it doesn't appear to be using git branches at all, and they are breaking

Re: [vpp-dev] Timer expiry spikes in TW timer implementation

Thanks Dave!!!. I could see precision was indeed the problem. I think it is because the slots are missed due to below check in tw_timer_expire_timers_internal(...) when now time is behind the calculated next_run_time. * /* Shouldn't happen */* * if (PREDICT_FALSE (now < tw->next_run_time))* *

That's as it is now. A rework of the code is planned, no ETA yet... Quoting mik...@yeah.net (2018-12-12 02:05:40) >W...What??? So the only way to make ip reassembly working correctly is to >keep one or more  interfaces attached to a single worker thread? >That does not sound efficient

Re: [vpp-dev] 2MB vs 1GB hugepages on ARM ThunderX

It would be great if we could figure out the reason. The contiv-vpp documentation needed to spell out that you need 1GB hugepages precisely because 2MB pages don't work. And there's also dpdk documentation [0] which doesn't mention the hugepages problem, making it seem like it shoudn't be an
