Compile a Linux module for current (5.25) batocera?

Hello, I have a dual Wii Classic Controller to PC USB Adapter which isn't quite supported (I posted the gory details on reddit). I suspect it's a Linux issu...

Hi 3615ulla ,
Good job !
And maybe you can help me :
I have 2 Playstation2 controllers with a USB adapter.
I can't use them for Batocera because the hid-sony driver doesn't map PS2 buttons correctly since kernel 4.10.
The solution by Silver-X is here:
https://www.linuxquestions.org/questions/linux-games-33/playstation2-controller-with-usb-adapter-need-help-getting-additional-buttons-to-work-4175643583/
It works with my Zorin OS but I'm not sure I have the skills for Batocera.
I'll try, but if you can guide me, it will be easier for me ;-)
See you soon
Lionel

Hey Lionel, sorry I just checked my account this morning, oops! :-)

Exactly what is the USB converter you have? The one I bought from Liksang (a couple of years ago at least) might be PS1 only. What does lsusb give you?

So looking through the thread you linked, basically what these people did is to take the 4.9 working hid-sony module and compile it with a more up to date version of the kernel (4.10). The module source code for hid-sony.c and hid-sony.h is in this zip that was linked in the thread: https://sites.google.com/site/panicus/Sony-HID-Downgrader.zip

You could follow my steps after overwriting the current hid-sony.c / hid-sony.h in your kernel_source/drivers/hid/ with the ones from this zip.

if after "make -j4 linux-rebuild" you have a file called output/target/lib/modules/5.4.16/kernel/drivers/hid/hid-sony.ko, you're all set to try it out!

No idea whether this will work or not. The proper way would be to diff the .c / .h files and try and understand where the bug was introduced.

Let me know if the overwrite method helps or not.

Cheers :-)

Hi 3615ulla !

lsusb gives this :
Bus 002 Device 005: ID 054c:0268 Sony Corp. Batoh Device / PlayStation 3 Controller

I will try to compile this night ;-)

See you soon,
Lionel

PS : 3615ulla is from french minitel ?

Hey Lionel,

the nickname is from a 90s French song. I don't know if you know it, but it made me smile ear to ear when it first came out... a few years ago, was it? ;-)

I just had a look at the manufacturer id / device ID you gave me: https://wiki.gentoo.org/wiki/Sony_DualShock -- Says DualShock 3 / Sixaxis ? Is your USB converter pretending to be a DualShock 3? Very strange!

But that "sixaxis" thing made me think...

I did a diff between the two files and they're not that different, but there's a missing static u8 sixaxis_rdesc[] in the new one... I think the code may have been reorganised at some point and some buttons from the Sixaxis fell through the cracks.

Let me know if you do manage to compile the old module, I'm a lot more optimistic than I was this morning.

Bonne nuit man, bon confinement :-)

Thanks a lot for your help 3615ulla (I love it : "C'est toi que je t'aime (Vachement beaucoup)" 1992, Les Inconnus ;-))

So... I think I did wrong:
Since I don't know how to use Docker, I did this:
git clone https://github.com/batocera-linux/batocera.linux.git cd batocera.linux git submodule init git submodule update make O=$PWD/output/x86_64 BR2_EXTERNAL=$PWD -C $PWD/buildroot batocera-x86_64_defconfig

After about 12 hours (!), the compilation was stopped by an error: Failed to download "kodi-superrepo-repositories 0.7.04".

And on the other hand, when do I have to overwrite the hid-sony sources ?

Bon courage également pendant ce confinement ! 😉

Hey Lionel,

I think you forgot to checkout the 5.25_fixes branch, check my instructions above ;-)

git clone https://github.com/batocera-linux/batocera.linux
cd batocera.linux
git checkout 5.25_fixes
make clean
make batocera-x86_64_defconfig
make -j4 linux

Here's a link to one I compiled for you, let me know if it at least works so you don't have to struggle on for another 12 hours :-)

Hi 3615ulla,
After git clone https://github.com/batocera-linux/batocera.linux
and
cd batocera.linux
git checkout 5.25_fixes gives an error : unknown git file
For instancegit checkout master is OK
but make clean gives Makefile:18: *** "docker not found!"
same result formake batocera-x86_64_defconfig gives Makefile:18: *** "docker not found!"

😓

3615ulla

Oh no!

It looks like that branch I was using is now gone or was merged back. Shame a batocera-5.25 tag wasn't created...

Anyway, the first line when I do git log --oneline is:

b0652e6842 (HEAD -> 5.25_fixes, origin/5.25_fixes) Merge pull request #1355 from Genetik57/cleaning-batocera_conf

Does that help at all? Sorry, I don't know git, only super basic usage 😓

Hi 3615ulla,

Hurrah !!! After hours and hours of reading and translating (I’m not very good in English…) of Docker, Git and Linux compilation and after some trials and errors, I finally managed to use my old PS2 controllers with Batocera :-))
I will open another post to explain my procedure but what I can already say is that there is no need to find a Git branch with the kernel used in Batocera : I chose “Custom kernel” and typed “5.4.16” in make linux-menuconfig !

In any way, thank-you very much 3615ulla
Lionel

My issue is solved 😀

3615ulla

Sorry Lionel, just saw this!

I was hoping my message to the general board about the 5.25 github tag would’ve gotten an answer, but it didn’t / hasn’t yet (there’s always hope). https://forum.batocera.org/d/3705-git-tag-for-batocera-525

So you managed to sort yourself out and even wrote a tutorial? That’s amazing! Did you see the last few steps of what I wrote about overlayfs to make your changes “stick”? Hope this helped.

By the way, I got this one for my Gamecube controllers: https://www.aliexpress.com/item/4000562126493.html – It’s arrived but I haven’t had a chance to test it yet with Batocera. I see more trouble in my future..

Have fun and remember Batocera IS the game ;-)

Yes you’re right, it’s necessary to run the script batocera-save-overlay to make the new module persistent on every reboot. Thanks 🙂
Here, my tutorial :

EDIT : Scott Shumate just proposed a patch to LKLM here : https://lkml.org/lkml/2020/5/13/1323

Cheers @3615ulla
👍 👍 👍

hey 3615ulla thank you for making this thread. I have the same Wii adapter and it’s hard to find any info. Would message you if I could as I’m not using Batocera. I am trying to get this adapter working for 2 controllers in Ubuntu. They are acting just as you described initially. They are loaded with hid-generic even after having the system load hid-sjoy at boot. Is that a problem? Maybe I can just tell hid-generic to treat the device ID as 2 controllers and not 1. That’s all you had to do in hid-sjoy.c, right? Do you still have the changes you made to that file?

I’m using fighsticks (nothing actually analog) so the hid-quirks stuff won’t be an issue.

3615ulla

Sorry @barnw0l, I dropped the ball on this, didn’t I?

All I was able to do was to dig my kernel source with the changes I talked about (check the differences with the .bak original files included in the zip): https://www.dropbox.com/s/lvvgxip8v1sfv6l/my_hid.zip?dl=0

EDIT Reading your post again, you mentioned not using Batocera. You should be all set with the zip above and I also updated my first (or second) message to show where what goes where a bit better.

Let me know how you’re getting on and if you get a chance to put it all back together, do let me know. The multiple lockdowns we’ve gone through have left me a lot dumber than I used to remember I was :-)

~~I haven’t tried any of this on a recent version of Batocera though. I was waiting for a replacement computer to play with and… I got distracted with other things.~~

~~@liOnux33 wrote a tutorial which may also be useful: https://forum.batocera.org/d/3796-tuto-make-your-ps2-controller-works-completely-with-a-cheap-usb-adaptor~~

Stay safe mate!

for future generations:

Just sat down at this finally, and didn’t take much time. Some searching related to 3615ulla ’s files brought me to this solution. All Ubuntu needed to see this as two controllers was adding the following to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub:

usbhid.quirks=0×0925:0×03e8:0×040

Apparently it’s a typical Linux “quirk” when two controllers are using one USB.

Cheers!

Thanks so much @3615ulla I should be able to sort this out now, next crack at it
