OSS + ELC EU 2026

Since v4.15 the kernel has support for the second version of the Raster Graphic Acceleration (RGA) IP core of Rockchip SoCs.
The newer RK3588 SoC additionally ships two RGA cores with version 3 and so I was tasked to extend the driver to support them.

7 months and 7 patch series versions later the driver was merged in Linux v7.2.

The talk walks through my journey to getting my first driver upstream. It shows where I had understood things the wrong way, where I've tried to do too much and where I've had to invest more work. Spiced up with some anecdotes about erroneous manuals, erratic hardware behavior and errors which only arise under load.

The talk is intended for beginners who are interested in doing mainline work. Besides showing the effort required and the frustrating moments, I want to encourage putting in the effort and showcase some of the nice solutions it has produced.
