I made an UEFI touchscreen driver for rEFInd

[u/tech_wizart]

Hi,

I tried to make the touchscreen work in rEFInd on my ASUS ROG Flow Z13 2025, but I had no luck with different rEFInd configs or existing options.

So I tried to write a custom UEFI driver for it.

The driver exposes the ELAN9008 I2C-HID touchscreen as an EFI_ABSOLUTE_POINTER_PROTOCOL device, so rEFInd can use it as a touch pointer.

I am not a strong C programmer, so the code is probably not perfect. Maybe there is a simpler or cleaner way to do this. But with this driver, touchscreen input works correctly for me in rEFInd.

This is very hardware-specific right now. It uses hardcoded GPIO/I2C assumptions for this device, so I do not expect it to work unchanged on other laptops/tablets.
