Open Source Summit and 2018 Linux Plumbers Conference

Open Source Summit: Innovation, Allies, and Open Development
August was an exciting month for Linux and open source, with the release of Linux kernel 4.18, a new ebook offering practical advice for enterprise open source, and the formation of the Academy Software Foundation. And, to cap it off, we ended the month with a successful Open Source Summit event highlighting open source innovation at every level and featuring keynote presentations from Linus Torvalds, Van Jones, Jim Zemlin, Jennifer Cloer, and many others.
In his welcoming address in Vancouver, The Linux Foundation’s Executive Director, Jim Zemlin, explained that The Foundation’s job is to create engines of innovation and enable the gears of those engines to spin faster.

LSS/OSS NA 2018 [Ed: Microsoft bought a keynote from the Linux Foundation. Yesterday the Foundation linked to 3 Microsoft promotional things. One was a month old, the other 3 months old. Makes one wonder if some Microsoft people now have editorial control at there too.]
There was a talk on security in Zephyr and Fuchsia. While the focus of the conference is Linux, there's a growing interest in running Linux in conjunction with processors running other operating systems. Zephyr is an open source RTOS targeted at processors with a smaller footprint than Linux. Most of the security improvements have been adding features to take advantage of the MMU/MPU. One of those features was userspace support, which is always a bit of a surprise to hear as a new feature. Fuchsia is Google's new microkernel operating system. There's some argument that microkernels offer more security than Linux since more parts can run in userspace. Much of the talk was about the resource and namespace model. There's been a good deal of work put into this but it was noted much of this is still likely to be reworked.

Someone from Microsoft talked about Azure Sphere. Azure Sphere is Microsoft's attempt at an IoT based microprocessor that runs Linux. The real challenge is that the device has 4MB. The talk focused on what kinds of optimizations they had to do to get it to run in that space. There's been similar attempts before but 4MB is still incredibly impressive. I'll be keeping an eye out when the patches go upstream (and maybe buy a device).

Devicetree Microconference Accepted into 2018 Linux Plumbers Conference
We are pleased to announce the the Devicetree Microconference has been accepted into the 2018 Linux Plumbers Conference!
[...]
Additional possible issues to be discussed may include potential changes to the Flattened Device Tree (FDT) format, reducing the Devicetree memory and storage size in the Linux kernel, creating new architecture to provide solutions to current problems, updating the Devicetree Specification, and using devicetrees in constrained contexts.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
