KernelUploadRightsApplication

I, Emil Renner Berthing, apply for the Ubuntu Kernel Uploaders team membership, to get upload rights for the linux-* packages.

Who I am

I am a kernel engineer working on the Ubuntu Kernel Team at Canonical since June 2022. Since then I've taken over the Ubuntu kernels for RISC-V.

I received my master's degree in Mathematics with Computer Science from Aarhus University 2009.

My Ubuntu story

I've been running Linux since about year 2000 and building my own kernels shortly thereafter. In the beginning I was distro-hopping a lot until settling for Archlinux for a long time. However that was only on my personal computers. When I was asked to help install Linux for others it has always been Ubuntu when a different kind of simplicity was required. Later while working for a big web-hosting company I was also heavily involved in switching their whole fleet from Debian to Ubuntu. I was in the "base" team responsible for building a solid base for the web, mail, network and other teams to build on.

My involvement

At Canonical I've been exclusively focussing on the RISC-V kernels. Both keeping them all up to date as part of the SRU process, but also preparing the kernels for new releases. That is backporting, testing and applying upstream and out-of-tree patches to support various RISC-V platforms like the Allwinner D1 based boards (Nezha, LicheeRV), the StarFive JH71x0 based boards (Starlight, VisionFive 1 and 2) and Microchip's PolarFire SoC.

In parallel I'm also involved with the upstream RISC-V kernel community reviewing and upstreaming patches. In fact the patches for the JH7100 based boards we use in the starfive kernels are mostly my work from before I started at Canonical.

General feedback

I have sponsored a large number of packages prepared by Emil, they have all been prepared with care and attention to details. On corner cases where issues were spotted, Emil quickly learned from the feedback given and avoided the same issues in the future.

Although Emil has worked almost exclusively with RISC-V kernels, he has gathered above average packaging experience by working with almost all possible packaging work needed on the Kernel Team (e.g. new packages, backports, unusual derivative dependencies, etc). Therefore I believe this more than compensates for Emil lack of experience with other kernels apart from the RISC-V ones.

I'm +1 for granting Emil upload rights for kernel packages and I'm totally confident that he will continue producing packages with quality and following the SRU rules and procedures.

Areas of Improvement

My only suggestion is that when time permits, Emil could start investigating the current regression tests issues with the RISC-V kernels and possibly consider expanding the test coverage.

General feedback

Majority of packages I have sponsored from Esmil have been flawless. Esmil has a good feel for which changes should be contributed where, he doesn't blindly follow status quo, and instead contributes improvements to the unstable/generic/kteam-tools that make riscv kernel maintenance easier, but all other kernels too.

Specific Experiences of working together

See my name above

Areas of Improvement

Potentially need more experience with ESM, private kernels, dkms modules, and general .deb userspace packaging. This would help to gain experience for becoming Ubuntu Core Dev in the future.

As a sponsor, just copy the template below, fill it out and add it to this section.

Thadeu Cascardo

General feedback

I have reviewed Esmil kernel packages with only meta dependent packages. When preparing an underspin (where a base kernel has moved on further), Esmil did base on the wrong base, but was able to quickly understand the situation and fix it. I trust Esmil will avoid such situations in the future because he has done so in future uploads.

Specific Experiences of working together

As above, I uploaded riscv main and meta packages, including backports. He was able to fix an underspin that was done on an incorrect base.

Areas of Improvement

Esmil should build further experience with kernel uploads by doing some kernels with signed and lrm, and find out more corner cases and not be afraid to ask questions on how to proceed. Examples would be cases where dependent packages have followup patches on a security respin, or when variants are changing.
