🎉Linaro is at #OSSummit! Come see us at booth G/S8 to learn more about ONELab, Linaro #LTS, our training services and more. Hope to see you there! #opensource

@pdp7 you need to pay attention Drew :-) don't blame you as I came a bit earlier and was doing my thing before this one started

let's catch up later...

@LinaroLtd @arm @linuxfoundation
It is always fun to hear Linus speak
The venue looks great too

The Linux Plumbers Conference is just in three days and I am looking forward to it. I see plenty of interesting topics, so the conference looks promising. If Devicetree is something of interest for you, please come visit "Devicetree Birds of Feather" session on Friday morning:
https://lpc.events/event/18/contributions/1783/

P.S. If you want to grab a beer or chat, find me in the halls or get in touch via email/fedi. I won't be attending OSSE, though. Only Plumbers.

If you are at the #ossummit in Vienna and you are an AOSP developer, then I would like to invite you to the AOSP Birds of a Feather meeting on Monday 16.09.24

Linux 6.12 To Support Arm's Permission Overlay Extension

The 64-bit ARM changes were submitted in advance for the now-open Linux 6.12 kernel merge window. There is work for Arm on the confidential computing side this cycle and other new features...
https://www.phoronix.com/news/Linux-6.12-ARM64-Changes

I’m happy to announce the Amlogic ARM64 Device Tree is now fully documented in linux-next, ready for v6.12!

Since the beginning of Device Tree on Linux, we documented how it should be written so drivers could know what to expect, it’s called “bindings”, it’s a sort of “contract” between Device Tree and drivers.

But those were written in human readable open text format, without any automated way to verify Device Tree files. There were numerous attempts, but ultimately Rob Herring leveraged JSON Schema [1] into “dtschema” [2] leading to this patch serie https://lore.kernel.org/all/20181005165848.3474-1-robh@kernel.org/.

Thus “dtschema” made it possible to write bindings in YAML and the developed scripts would convert Device Tree in YAML and run a validation with JSON Schema validation. This was merged in end of 2018 then conversion of the text files in YAML files started.

For reference, there were 3278 text bindings in Linux 4.20 git tree, in today’s Linux next for v6.12 only 1250 text files remains but there’s 4345 yaml files now! In addition to the transition to yaml bindings, new platforms were introduced using the new format.

Around one year ago, I upstreamed support for the Snapdragon 8 Gen 3, and it was fully documented from day 1, and most of the changes was yaml bindings change since the SoC was mainly an upgrade from the Snapdragon 8 Gen 2 I helped upstream 2 years ago.

Let’s go back to Amlogic, were I started converting the text file to yaml bindings in August 2019 (see [3]), and finally ended the transition early this month with the patch [4]. This makes the Amlogic ARM64 Device Trees join fully documented along other platforms like Samsung Exynos

If you want to know more about Device Tree validation, you can look at my @LinaroLtd colleague @krzk talk he did in this year's #EOSS in Seattle https://sched.co/1aBEf!

Thanks for reading !

@LinaroLtd we are at @linuxfoundation #OSSSummit, come and say hello to us at the booth G8 in Hall E to discuss Open Source Software on @arm

@lumag @LinaroLtd is at #OSSSUMMIT, do visit our booth to know about awesome work that @LinaroLtd does in open source world on ARM

Be sure to visit our stand at #OSSEU24, #ossummit we don't want to bring anything back.

Exciting News for Qualcomm Developers!

We’re thrilled to announce the first binary release of U-Boot for @qualcomm platforms! U-Boot now supports key functionalities like EFI booting, internal storage, USB, and even KVM support on select boards like the RB5.

Learn how to flash, build from source, and explore the deeper integration of U-Boot in the Qualcomm ecosystem.

The BUG is a feature...

Never thought I would say this... Realised it after I said it...

are there any Fedora folks here who might be up for packaging Alpine's package manager (apk-tools)? As part of @postmarketOS systemd support I'm going to be adding pmOS support to mkosi, but right now Arch Linux is the only distro with apk-tools packaged, having it in Fedora would help a _lot_ to simplify things for the systemd maintainers.
