While developing operating system infrastructure for industrial devices for our customers, we build lots of embedded Linux board support packages, kernels, bootloaders etc. at Pengutronix. Although ICECC should be a good tool to distribute the computing power to a cluster of machines, it recently turned out that things are not that simple.
Some days ago, Greg Kroah-Hartmann wrote a great blogpost about Which Stable Kernel One Should Use?. I fully agree with his position; however, I'd like to make some additions for the industry device manufacturer use case and some common pitfalls and misunderstandings we see in that area.
This year, a team from Pengutronix attended FrOSCon in St. Augustin for the first time. We took the opportunity to shake hands, talk about our latest developments and meet hackers interested in working with embedded Linux.
Several i.MX SoC versions, for example i.MX7D, i.MX6SX and the i.MX8 derivates are asymmetric multiprocessing (AMP) systems: They have at least one ARM Cortex A core and at least one ARM Cortex M core.
Once in a year, mostly during springtime, no phone call is answered at Pengutronix, no customer Mail receives a reply, no BSP is built and no coffee machine gargles. But, no fear, this is not the end! It is just the time for something new! New ideas, focused development on new world domination plans and time to think outside the box. Yes, it's again the time for the Pengutronix TechWeek!
Auch dieses Jahr werden wir mit dem Team wieder zu den Chemnitzer Linux-Tagen reisen. In dem Business Forum werden wir, wie auch in den letzten Jahren, auf einem Stand die neusten Demos präsentieren. Darunter wird auch die Demonstration der Open Source Grafik-Treiber (Etnaviv) auf dem neuen i.MX8M, eine 4-Video-Demonstration auf i.MX6 und unser bereits bekannter RAUC-Updating-Demonstrator sein.
