I have been contracting for the Linux Foundation for two years now, going onto the third, and it dawned on me that I have never done a retrospective or yearly report. This is useful for looking back on the year’s worth of accomplishments, both to understand how much I have evolved and to look for areas that I would like to improve upon going forward. I have struggled with imposter syndrome for as long as I have been involved with the kernel community, so looking back to give credit where credit is due for particular solutions is a good way to try and combat that.

This year, I had 132 commits accepted and merged into mainline. They can be viewed on the web or by running the following command in an up-to-date Linux repository locally using the following command:
$ git log \
--author='Nathan Chancellor' \
--oneline \
--since-as-filter='Jan 1, 2022' \
--until='Jan 1, 2023' \

You will notice that I spend a lot of time fixing warnings, which have been a higher priority ever since CONFIG_WERROR was introduced last year. allmodconfig enables CONFIG_WERROR, which is a common testing target for developers and continuous integration, so it is important to keep this working. As a direct result of that work and the work of others such as Arnd Bergmann, we were able to stop disabling CONFIG_WERROR for arm64 allmodconfig and x86_64 allmodconfig this year, which gives us leverage when things break. Linus himself has voiced displeasure when things break with clang (example) but that can only happen when the build with clang continues to work. Additionally, ever since GCC’s -Wmaybe-uninitialized was globally disabled for a normal kernel build in 5.7, clang’s -Wuninitialized and -Wsometimes-uninitialized have become a constant nuisance since developers will introduce them inadvertently and not realize it because GCC never told them about it. Some developers have started integrating clang testing into their workflows to help catch these, such as the netdev folks, who I regularly see tell contributors their patch has errors with clang, but it is a slow process; until then, we’ll be fixing them ourselves to keep the builds green.
There are a few different commits that I am particularly proud of due to how they tested me and forced me to dig deeper for an answer:
-
a8a4f0467d70 ("drm/i915: Fix CFI violations in gt_sysfs"): This one was particularly wild becuase it seemed so simple at first. I booted up my test Intel desktop, saw the failure, debugged for a bit, wrote the patch, and was so confident it was right that I considered not even testing the patch before sending it. I learned very quickly that is never a good idea since my patch was broken in its current state. As I read the code and started to fully understand what was going on, I started to worry I was not going to be able to fix it but at the end of the day, I am surrounded by people who know more than I do that I can ask for help and I have started to write development journals so that I am sure I understand the problem before starting a solution. This one was fun to have people review and test because it was so large but I am thankful for all the review that I did get, since it helped warp the patch into something that is worthwhile. -
52c9f93a9c48 ("arm64: Do not include __READ_ONCE() block in assembly files"): This one was fun to debug because I got to the point ofgit diffing preprocessed assembly files :) Debugging header include issues is probably one of my least favorite things but this was high priority because the commit that introduced this breakage was a part of the Spectre-BHB fixes, which were going to be rapidly backported to the stable trees and potentially break downstream consumers of Clang’s LTO, like Android. I felt really good once I had gotten the commit message written because it felt like it was going to make a real, tangible impact somewhere. -
e9c281928c24 ("kbuild: Make $(LLVM) more flexible"): While I cannot claim credit for the implementation of this commit, I am proud of this commit because it is addressing a core Linux kernel developer concern that was brought up to us, which allows them to continue to test with LLVM. It is very important to listen to developers and maintainers when they complain about our project because they are the ones we have to get buy in from. Our project could collapse if maintainers decide they do not want to put up with the idiosyncracies of building the kernel with LLVM or even worse, refuse to let the kernel be built with LLVM, likeld.gold. That is an obvious extreme that is unlikely at this point, especially when core maintainers have openly accepted our approach to maintaining LLVM support, but it is important to remember that since the kernel and LLVM are always evolving, we have to be present and responsive at all times.
It is important to keep in mind that sending patches is only part of the development process. The others are reporting problems and testing and reviewing solutions to those problems. The kernel keeps track of these through particular tags: Reported-by, Reviewed-by, and Tested-by. In 2022, I provided those tags on 188 patches. The break down of patches that contained:
Reported-by: 48Reviewed-by: 91Tested-by: 84

As a direct result of this, I appeared in the top testers in the 5.19 development cycle and 6.1 development cycle.
LLVM
I am far from a large LLVM contributor but I do have occasional patches there as part of this work. This year, I had 4 patches to LLVM, which were all just reverts of patches that caused issue for us, which I was a little bit more aggressive about this year due to our use of LLVM ToT in continuous integration.
LLVM contributions in 2022 (GitHub)
74bace2dfe57 ("Revert "[AArch64] Improve codegen for shifted mask op"")
23c50432fb25 ("Revert "[AArch64]SME2 Outer Product and Accumulate instructions"")
4e0008dcbe9f ("Revert "[InstCombine] try to narrow shifted bswap-of-zext"")
22eb1dae3fb2 ("Revert "[AArch64] Adds SUBS and ADDS instructions to the MIPeepholeOpt."")
Tooling
We have a few different repositories in our GitHub organization that we use for testing and development, which I call “tooling”. Tooling is very important for repetitive tasks or tasks where you want to take the human out of the equation so that mistakes are less likely, such as a bisect. Additionally, there are some other repositories that we rely on, like TuxMake, that I consistently contribute to.
A common theme this year is moving more and more infrastructure to Python where possible, as it gives us more flexibility in writing scripts that can do complicated things without worrying about how we are handling input, because we actually have types and data structures in Python, unlike shell. In particular, moving boot-utils to Python has increased what we are able to do with it, such as passing along a folder from the host to the VM.
Like previously, I have included the git log output with direct links to commits, along with a web link to browse the history there.

Behind the scenes
There are always things that require time but do not always show tangible results. There are three things that I think fall under this category:
- Issue tracker management: Keeping a clean and accurate issue tracker is critical for few reason.
- It gives a good high level overview of the “health” of the project. We want our issue tracker to be an accurate representation of how much help we need (since we always need it…)
- It helps assign priority to certain issues. If we have a lot of open but resolved issues, it can be hard to decide what needs to be worked on next.
- The issue tracker is a wonderful historical reference. We use the issue tracker to keep track of mailing list posts and such so it is important that those links are as acccurate as possible and have as much information as possible in case we have to look back five years later to wonder why we did something the way that we did.
- Mailing list reading: We are not Cc’d on every issue related to
clang, even though sometimes it is the compiler’s problem or a known difference between the toolchains that we have already figured out. By monitoring the mailing list for certain phrases, we can provide assistance without being initially notified, which developers do appreciate. - Hardware testing: Every linux-next release, I built and boot kernels on a variety of hardware to test for issues, as some problems only show up on bare metal or with a full distribution. I now have a script to drive a full distribution QEMU on a variety of architectures to make some of that testing and debugging easier but bare metal is always an important testing target, since that is where the kernel will run the majority of the time.
Special thanks
Special thanks to Google and the Linux Foundation for sponsoring my work. I am in a very fortunate position thanks to the work of many great and suppportive folks at those organizations and I look forward to continuing to contribute under this umbrella for 2023!
