Many of these older generation "Windows on Snapdragon" laptops unfortunately did not use fast NVMe storage however, only slow eMMC and eUFS (Universal Flash Storage), the latter currently being unsupported by OpenBSD.
This is commit is plumbing work fixing GPIO support, which indirectly makes the keyboard work. I don't have any boot logs for the machine, but as I understand they have standard Microsoft-compatible HID keyboards/touchpads that work with OpenBSD's existing drivers.
And, to your point, if it was reverse engineered, that's more reason to comment, not less, because (a) memory is fleeting (b) if I wanted to contribute, I could read along about how Zen Master OpenBSD Reverser found those so I could go find more
However, that specific device doesn’t have good support. Would take some developer time to do so… (and not sure if that will happen)
