Change Details

- Install patched `intelspi` - Add `hint.spigen.0.at="spibus0"` to `/boot/device.hints` - Boot on a MacBook with SPI input devices, use an external USB keyboard - `kldload intelspi spigen` - Try `spi -d r -c 256 -v`, observe all-zero output (not a timeout error!) - Install [[ https://github.com/DankBSD/base/commit/ce415a48c5ad49bd3147055a0547b82eb8ccbbee | WIP topcase driver ]] (currently just toggles SPI on via ACPI), kldload it - Try `spi -d r -c 256 -v` again, observe interesting data packets :) - The "proper" speed for these devices is 8MHz, but even the default 10MHz works fine for me. Try changing speeds with `spi -s ...`. Interestingly I've noticed that after going too low (e.g. 100KHz), going back up to 1MHz and up results in timeouts again. Fascinating.

Currently: buildkernel installkernel from [[ https://github.com/DankBSD/base | here ]], boot on a MacBook with SPI inputs, `kldload atopcase` (The input driver will be submitted here too eventually, but it's a bit early right now)
