[Podcast] Kernel Panic - Board on Fire ~~> #001: Speculative Execution und ein Execute Never Bit

In der ersten Folge des Kernel Panic Podcasts geht es um ein Problem mit dem sich mein Kollege Ahmad Fatoum beschäftigt hat. Wie so oft beginnt die Geschichte mit einer Aufgabe, die eigentlich™ in fünf Minuten erledigt sein sollte, driftet aber rasant ab in eine Fehlersuche in den Untiefen der Systemprogrammierung. Es geht um Caches, Adressbereiche, Spekulative Ausführung von Code, um Funktionierbits und auch um Nicht-Funktionier-Bits.


Pengutronix Kernel Contributions in 2021

2022 has started, and although Corona had a huge impact on our workflow, the Pengutronix team again made quite some contributions to the Linux kernel. The last kernel release in 2020 was 5.10, the last one in 2021 was 5.15, so let's have a look at what happened in between.

"FOSDEM is a free event for software developers to meet, share ideas and collaborate. Every year, thousands of developers of free and open source software from all over the world gather at the event in Brussels. In 2021, they will gather online." -- FOSDEM


15 Years of i.MX in Mainline Linux

Today it has been 15 years since we mainlined support for Freescale/NXP's i.MX architecture in the Linux kernel! That was one small step for [a] man, one giant leap for (industrial Linux users') mankind :-) Here is some background about why it happened and what you might want to learn from history for your next embedded Linux project.


What Kernel Should I Use (Embedded Edition)

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.



First i.MX 8M Patches posted for Mainline

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).


Pengutronix Contributions to v4.10

Here is a short report about Pengutronix' contributions to the 4.10 kernel. It mainly contains more improvements for the i.MX6 graphics and video subsystem, Etnaviv, Marvell Orion and Altera SoCFPGA.
