0x17: Tutorial, Lightweight Approach to Kickstart Development of a NIC Driver
by Jamal Hadi Salim 22 Sep '23

22 Sep '23

So your NIC hardware is not ready but you need to write the driver.... In this tutorial, David Ahern will guide us to a lightweight approach for developing S/W and H/W in parallel. As H/W design discussions progress, a simplified software model can be built in parallel, capturing the essence of the data pipeline and descriptors. When run with the Linux networking stack, design proposals can be examined from a S/W perspective with actual data based on a networking load. David will show how to integrate a S/W only device model with Linux and the networking stack - from mimicking PCI probe and init, creating a netdevice, configuring queues and using those queues to send and receive data. Namespaces are used to imitate hosts and allow end-to-end connectivity, facilitating a complete, closed-loop datapath cheers, jamal

0x17: Reminder, Early bird registration still on
by Jamal Hadi Salim 21 Sep '23

21 Sep '23

Folks, A reminder that early bird registration is open for another 9 days. https://netdevconf.info/0x17/pages/registration.html The earlier you register the better for us as an organizing committee in terms of planning (we have to feed you for example and the caterers tend to be mean when you change the numbers on them ;->). So register sooner than later please! cheers, jamal

0x17: Tutorial, Introduction to time synchronization pt. 3
by Jamal Hadi Salim 21 Sep '23

21 Sep '23

Maciej Machnikowski is back for the trilogy on time synchronization! Our esteemed instructor, Maciej, builds on his previous two sessions[1][2] to teach us more on this important topic. In this session he will discuss the latest advancements in linuxptp 4.0, such as dynamic clock reconfiguration in ts2phc or support for virtual clocks in the tool and the Linux Kernel. The tutorial will go into the fundamental concepts of Precision Time Measurement (PTM), which offers a pathway to enhance the synchronization of time between the Network Interface Card (NIC) and the Central Processing Unit (CPU), and briefly introduce kernel APIs dedicated to supporting it. Maciej will segway into a discussion about practical techniques for effectively monitoring a PTP-synchronized system and conducting tests on a PTP Hardware Clock (PHC) through the utilization of diverse tools. Notably, tools like "phc_ctl" and "testptp" offer distinct capabilities. And finally this tutorial will conclude with a practical example of deploying ptp4l and phc2sys in combination with chronyd or ntpd to synchronize the system clock to NTP and PTP time sources using a timemaster tool. cheers, jamal 1. https://netdevconf.info/0x15/session.html?Introduction-to-time-synchronizat… 2. https://netdevconf.info/0x16/sessions/talk/introduction-to-time-synchroniza…

0x17: Looking for AV knowledgeable people
by Jamal Hadi Salim 11 Sep '23

11 Sep '23

We have some challenges in Audio Visual for 0x17 in trying to get a commitment from AV companies in time for the conference. If you have some knowledge in this space please ping me. We are likely going to run AV ourselves. So any knowledge on what minimalist equipment to set up, design of the layout: mikes, speakers, cameras etc is helpful. The conference is hybrid, so think about remote participation as being a high priority etc. As much automation as possible is important as well. We have some ideas but we are not experts... Unicast responses to me. cheers, jamal
