Daniel Barlow	f1b7780537	speed up kernel build ... by having two separate derivations for patching the kernel source tree and building it, we have to copy said source trees from one store location to another which takes non-neglible time on spinning rust (literally minutes on my machine). Replace with a single derivation that can do more things on one tree in-place	2022-10-19 17:34:22 +01:00
Daniel Barlow	3ef30056c4	trim down the qemu kernel config ... just retain the options we need to pass the tests	2022-10-18 22:28:07 +01:00
Daniel Barlow	77922c875b	add per-device overlay ... presently this is used to reference the appropriate kernel and (if needed) openwrt source trees, but I would not be surprised if we find other uses	2022-10-15 18:55:33 +01:00
