Hello planet !

Introducing myself


My name is Romain, I have been nominated to the status of  Debian Maintainer recently. I am part of the debian-kernel team (still a padawan) since few months, and, as a DM, I will co-maintain the package raspi3-firmware with Gunnar Wolf.

Current contributions

As a kernel and linux en enginner, I focus on embedded stuffs and kernel development. This is a summary of what I have done in the previous months.

Kernel team

As a contributor, I work a various things, I try to work where help is the more needed. I have wrote a python script for generating debian changelog in firmware-nonfree, I have bumped the package for new releases. I bump the linux kernel for new upstream releases, I help to close and resolve bugs, I backport new features when it makes sense for doing so, enable new hardware and recently I have added  new flavour for the RPI 1 and RPI Zero in armel ! (spoil)

Raspi3-firmware

I have recently added a new mode in the configuration file of the package that let you device what you would like to boot from the firmware. You can either boot a linux kernel directly, passing the adress of the initramfs to use, a baremetal application, or a second level bootloader like u-boot or barebox (personnally I prefer u-boot). From u-boot then, you can use extlinux and get a nice generated menu by uboot menu. I have also added the support for using the devicetree-blob of the RPI 1 and the RPI Zero W when the firmware boots the kernel directly. I am also participating for reducing lintian warnings, new upstream release and improvements in general.

U-Boot

I have recently sent a MR for enabling support for the RPI Zero W in uboot for armel and it was accepted (thanks to Vagrant). As I use U-Boot everyday on my boards, I will probably send others MR ;)

Raspberry Pi Zero

As written described above, I have added a flavour for enabling support for the RPI1 and RPI Zero in armel for Linux 4.19.x. Like the Raspberry PI 3, there are no official images for this, but you can use debos or vmdb2 for building a buster image for your PI Zero. I have personally tried it, at home. I was able to run an LXDE session, with llvmpipe (I am still investigating if vc4 in gallium works for this SoC or not, while it's working perfectly fine for the PI3, it fallback to llvmpipe on the PI Zero).

Raspberry Pi 3

As posted on planet recently by Gunnar, you can find an unofficial image for the PI 3 if you want to try it. On buster you will be able to run a kernel 4.19.x LTS with an excellent DRM/KMS support and Gallium support in mesa. I was able to run a LXDE session with VC4 gallium here !

Future work


I will try my best to get an excellent support for all Raspberry PI in Debian (with unofficial images at the beginning). Including kernel support, kernel bugs fixes or improvements, debos and/or vmdb2 recipes for generating buster images easily, and even graphical stack hacks :) . I will continue my work in the kernel-team, because there are a tons of things to do, and of courses as co-maintainer, maintain raspi3-firmware (that will be probably renamed to something more generic, *spoil*).

Add support for F2FS filesystem to GRUB and initramfs-tools

-
Hi there, For these like me who want to change their root filesystem to F2FS, I have enabled support for adding the F2FS module in the EFI signed image of grub in Debian (commit) . So the grub EFI image can load configuration, kernel images and initrd from a /boot that is formatted in F2FS (the upstream grub supports the filesystem since 2.04). Now that the kernel is loading it must be able to mount the rootfs. In Debian, a lot of features like some filesystems or some drivers are built as modules, this allow to be able to boot and work on a lot of different machines without have to build-in statically everything into the linux kernel image. This is why we use an initramfs , it offers a variety of cool features and detects magically some details for you like "load the brtfs module or your favorite emmc driver as module". If you want to use F2FS as your main filesystem on your rootfs, we need to add F2FS as base module into initramfs-tools (that handles all the scripts and...

RaspberryPi 3 desktop image running Debian Buster 10.2

Hi ! The Capitole Du Libre 2019 happened two weekend ago on 16th-17th November. I have helped the DebianFrance team on the Debian booth. It was a super event with a lot of cool and interesting people ! We promoted the Debian project and I have also presented a demo of a Raspberry PI 3 running a fresh debian 10.2 with a mainline linux kernel (for instance 4.19.x) with V3D or llvmpipe.  The different persons I met were very interested by the availability of the image, so I have decided to write a debos recipe from scratch for ARM64-based RaspberryPI. This is a desktop oriented image. It will start an lxde session automatically with the "pi" user. The root accound is locked but you can use sudo with the "pi" user. You can find the recipe here . You can build an image ready to flash with the following commands: $ git clone https://salsa.debian.org/raspi-team/image-specs.git $ cd image-specs/debos $ debos raspberrypi-desktop_arm64.yaml It should produ...

My Raspberry PI 4 4GB

Hi, I have received my Raspberry PI 4 4GB that has been funded by the Debian project. I would like to thank the DPL and Gunnar Wolf for this (who vouched for me). So today, I have unpacked the board and tested it with the default flashed noobs/raspbian, so I check that everything is working as expected (from the hw point of view, I already had bad suprises in the past with some evaluation boards). Interesting topics will come soon, mostly about booting a debian testing/sid on it , adding support to raspi-firmware and the linux kernel for enabling support for the pi 4 and some variants drivers for the bcm2711. See you !
