I Got Into GSoC!
Wow, it’s really happening :D
After some warm-up and work put on, I got accepted into the 2023 Google Summer of Code program with the X.Org organization.
What I’m Going to Do
The title of my project is “Increasing Code Coverage on the DRM Code”. The DRM subsystem is the standard way to interact with complex graphics devices.
It provides many global helpers for use inside the drivers. As these helpers are used by many drivers on the DRM subsystem, testing those functions for asserting that no regressions are made is crucial for kernel development.
Many units test were written for those helpers with the KUnit framework. But there is still much work to do. Running the Gcov code covering
analysis tool, we see that just one file has 100% of code
coverage. Knowing this, I will create more tests for the
drm-format-helper.c. This file handles color format conversion.
Currently, the conversion functions can’t handle planar formats. Instead
of having the color information packed in a single plane, those have their
information separated into multiple planes. I pretend to add support for it by
This Summer, I will be mentored by:
What I’m Doing Right Now
During this community bonding period, I’m reserving time to review patches on
dri-devel mailing list and read more about the DRM.
These are my reviews:
In parallel, I’m trying to add support for the NV12 format to the VKMS driver. This would be nice for testing userspace programs that contain framebuffers with video. This is turning out to be bigger than I thought, as I need to add support for planar formats there and make the format conversion in software. Stay tuned for blog posts on that too ;).
See ya! :)
