Playstation DualSense controller support using hid-playstation driver

scrig_potato

Hello all!

Using a DualSense controller paired via bluetooth works ok, but I have trouble using two controllers simultaneously (for example, using a DualShock 4 and DualSense at the same time). Buttons seem to become remapped, and one controller will start to control the other input, etc.

Linux kernel 5.12 introduced hid-playstation, which is a full implementation of the playstation controller driver (https://www.spinics.net/lists/linux-input/msg70842.html)

Batocera is running 5.15 now, yet I don’t see the hid-playstation driver in /modules/5.15.11/kernel/drivers/hid/

And when pairing a DualSense controller via bluetooth, it seems to use the generic hid drivers.

What needs to be done to have Batocera utilize the hid-playstation driver for the kernel we use?

Thanks to all for maintaining Batocera and providing this great software!

scrig_potato If it’s in the Linux kernel, then it wouldn’t have its own folder for loading extra drivers. I think that’s how that works.
At least, if the drivers weren’t included at all, then your controllers would cease to function.
More likely, this is a bug with SDL or the drivers themselves. Perhaps they conflict with each other and attempt to use the same input events? You can test for this with evtest: https://wiki.batocera.org/diagnose_joysticks_issues

I’m happy to report that this is now fixed in the latest batocera release.

As of around 34 (and I think the release before it) the playstation dualsense controller is nicely identified by the updated playstation drivers. I guess the upstream kernel change got picked up. Thanks to the team for the updates to the kernel!

The lights on the controller are slightly different (an additional whilte light above the microphone input) and dmesg now says:
