Great success! :) My attempts on my Xiaomi Air 13: =2D Stock build time: ~50 minutes. =2D Custom kernel, starting from nothing: 5-10 minutes. It works, but the mousepad and the sound are missing. I can't figure which component is missing. Does anyone know if there is any reliable way to know the kernel config I need for that? =2D Custom kernel, starting from Linux-libre and removing components: 40 minutes. It works, but I don't understand why it's still so long to build. I've removed almost all devices I didn't need from the "device section", but this is clearly not the bottleneck.
