Try compiling "Linux driver for Dual Sense of PS5"

TL; DR I made a device driver module for the PS5 controller.

--The driver is by default, so enable it with make menuconfig! --The patch has a bug, so fix it manually!

Introduction

GIGAZINE had an article that looked interesting.

Sony officially provides Linux driver for PS5 DualSense

https://gigazine.net/news/20201226-sony-ps5-dualsense-linux-driver/

I applied all the above patches to Linux 5.10.2, which is the latest version at the time of writing the article on my Ubuntu 20.10, and executed the "bindeb-pkg" command to build the kernel, and the build succeeded. However, the kernel module of "hid-playstation" was not created and the driver could not be used.

Cheeks! !! Let's verify it. However, I don't have a PS5, so I checked if it could be compiled.

The Kernel is the same 5.10.2, and the working environment is ubuntu 20.10.

Download Kernel.

$ wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.2.tar.xz
$ tar xxvf linux*.tar.xz
$ cd linux*
$ mkdir build
$ cp /boot/config-`uname -r` build/.config

etc. Let's refer to https://gihyo.jp/admin/serial/01/ubuntu-recipe/0526?page=2 for this area.

Apply the patch

https://patchwork.kernel.org/project/linux-input/list/?series=404369

Download the patches (diffs) one by one from here and apply them with great care ...

Enable kernel settings

The default is OFF, so let's enable this.

Here, you have to enable it as shown below.

I tried compiling, but I get an error

Well, I compiled it, but I get an error.

I feel like the patch is buggy.

Hmmm, isn't it wrong here? "+" Is an obstacle.

Will result in a compile error. So you need to remove the "+" after applying the patch.

 #if IS_ENABLED(CONFIG_HID_PLAYSTATION)
 	{ HID_USB_DEVICE(USB_VENDOR_ID_SONY, USB_DEVICE_ID_SONY_PS5_CONTROLLER) },

If you make it again with this, you have successfully created hid-playstation.o!

The necessary ko is ready! However, I can't check the operation because there is nothing! !!

Summary: I made a module for the device driver for the PS5 controller.
