Not working on 12-inch MacBook Early 2015

[sporkl]

I recently tried to use this driver to get support for the built-in keyboard and touchpad on my 12-inch MacBook Early 2015. I have tried both the version available in the Arch User Repository (installed with yay), as well as cb22's version (installed manually). Neither have been successful at getting the keyboard and touchpad to respond.

I'm pretty new to Linux, so there is a fair chance that I did something wrong.

I don't know if this is helpful, but xinput list does display both the keyboard and the touchpad.

Thank you.

So this would be the MacBook8,1(cat /sys/class/dmi/id/product_name)? Is the applespi module loaded at all (lsmod | grep applespi)? And are the required pxa2xx modules loaded (lsmod | grep spi_pxa2xx)? What does dmesg | grep applespi show? And does libinput list-devices show any "Apple SPI ..." devices?

[sporkl]

Yes, this is the Macbook8,1. The applespi and pxa2xx modules are loaded. The output of dmesg | grep applespi is:

[    2.740531] applespi: loading out-of-tree module taints kernel.
[    2.797013] applespi: spi=device probe done: spi-APP000D:00

libinput list-devices shows Apple SPI Keyboard and Apple SPI Touchpad.

Interesting: what appears to be missing is the "applespi: modeswitch done" log message, which seems to indicate the SPI messages aren't being delivered properly. This sounds a lot like cb22#49, though that one so far has only appeared after doing a suspend/resume. But just make sure we're not running into a variant of cb22#71, can you add irqfixup to your kernel command line (either edit /boot/..../grub.cfg before rebooting, or edit the command line at the grub prompt during boot) and see if that helps?

Assuming the irqfixup doesn't help any, can you next try the following: reload the applespi module using

sudo rmmod applespi ; sudo modprobe applespi debug=0xd07

Then click some keys on the (laptop) keyboard, and finally show me the output of dmesg | applespi again.

irqfixup did not work. Apparently it was not found(?).

dmesg | grep applespi:

[    3.043395] applespi: loading out-of-tree module taints kernel.
[    3.100271] applespi: spi=device probe done: spi-APP000D:00
[  361.263544]  applespi_remove+0xcf/0x160 [applespi]

When running sudo rmmod applespi there was an error: rmmod: ERROR: Module applespi is in use. Trying to remove the modules that it depended on (led_class and crc16) would lead to a recursive "in use by"-- applespi is in use by led_class, led_class is in use by applespi. I used dkms to uninstall and reinstall applespi after rmmod and modprobe did not work.

Some other information that may or may not be helpful:

• I use Manjaro Linux running the Manjaro version of kernel 4.14
• The builtin keyboard on the laptop works fine in GRUB.

Wait, I just gave it another try. I used irqfixup incorrectly (I tried executing it as a command instead of using it as a boot parameter. As I said, I'm new to Linux). irqfixup did the trick.

Thank you very much for the help!
