Hello everyone. I was busy with the Linux kernel for most of the week. Let’s go over everything.
MicroBlocks Updates
MicroBlocks dev branch recently broke the MicroBlocks Zephyr Port. I sent a patch to the Discord channel, and it has been fixed.
Devicetree Compiler
A lot of work this week was focused on the device tree compiler. I have been working on adding support for path references in devicetree overlays. In the initial patch, some parts of the initial patch series can be sent as independent patches. So last week mostly involved getting those merged.
setprop namelen variants
Previously, all the setprop variants calculated length of property length from strlen. However, devicetree __fixups__ contains information regarding the position of a property to resolve, and thus cannot use these normal variants. Additionally, it is not allowed to use heap memory in many places in the devicetree compiler and related tools, and thus, there was a need for setprop_namelen_* variants of functions similar to how these exist for getprop_namelen_*.
The patch series has been merged now.
Clang format config
While working on the devicetree compiler code, I was using the clang-format config from the Linux kernel. As suggested by David Gibson, I sent a patch to add the clang-format config which has now been merged.
Path Reference support in Devicetree overlays
Since the related patch for setprop namelen variants has been merged, I have been working on version 2 of the path reference support patch. Since it is not allowed to use dynamic allocation, I have been able to get things working with adjusting offsets while growing. I still need to fix some tests and add new ones, but I should be able to post the patches this week.
BeagleBoard Rust Imager
As per the suggestion in the issue, I have been experimenting with moving around the configuration screen flow. A prototype can be found here. I have not yet finalized whether this should be merged.
Ending Thoughts
This was it for this week. Hopefully, this helps bring transparency regarding where the development efforts are concentrated, and how the community can help. Look forward to next update.
