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.
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.
Eight days after NXP announced the immediate availability of the i.MX 8M processor family, Pengutronix developer Lucas Stach today posted a first set of 11 patches to support i.MX 8M in the mainline kernel (linux-gpio, linux-clk, linux-arm-kernel and linux-netdev).
At the ELC Europe 2016 in Berlin our colleagues Jan Lübbe and Marc Kleine-Budde are talking about two interesting and important presentations about Kernel longterm maintenance strategies and verified boot.
