Note that this message is not about removing drivers, but about removing entries from /boot/device.hints (GENERIC.hints) (unless we intend to remove support for hinted devices entirely from isa(4)?). Was there a user report that motivated mentioning atkbdc here, or was that just based on past memory? I'd be really surprised if ACPI was failing to enumerate the keyboard controller and its resources at this point. It is debatable if we should make disabling ACPI work out of the box (which is what most of /boot/device.hints does) vs stripping more entries ouf of device.hints on amd64 (in particular, atkbdc, psm, the uarts, atrtc, and attimer). If we remove syscons that also removes the sc0 hint. It's less clear to me if we want to ban hinted ISA devices entirely. That pretty much breaks !ACPI booting which can matter for some custom appliance systems that use home-grown firmware that may not include a full DSDT. It's fine if we require those downstreams to ship a modified device.hints. I'm less convinced it's useful to require them to also patch isa(4) to support hinted children? -- John Baldwin
