Sony publishes an official Linux driver for Playstation 5 DualSense controllers
Looking up who Roderick Colenbrander is (person who submitted the patch over at https://patchwork.kernel.org/project/linux-input/patch/20201...), it seems they are the "Director of Hardware & Systems Engineering" over at Sony. I'd expect them to spend time on more higher-level things, but seems here they either was involved with actually writing the driver, and/or are just the public face for the patch. Seems unusual though. Kudos if directors at Sony still get to write code, especially low-level code like this.Edit: Seems there is more details in a almost year old article on phoronix (https://www.phoronix.com/scan.php?page=news_item&px=Sony-HID...):> Roderick Colenbrander of Sony who serves as their Directory of Hardware & Systems Engineering, chimed in on the matter of adding this Gasia controller support (And, yes, this is the same Roderick Colenbrander who in his spare time serves as a Wine developer and if going back to the early 2000's was the NVClock NVIDIA overclocking tool developer as opposed to being some eager Sony employee):So seems Roderick is a true hacker! I've used both Wine and NVClock in the past so if you're around here, thanks for your work on all these things and upstreaming them as well! :)
