Yesterday I committed apldcp(4) and apldrm(4). Together these drivers provide KMS (kernel mode setting) for the display subsystem on Apple M1/M2 machines. These drivers rely on up-to-date apple-boot firmware. If you're not using sysupgrade(4) to update, you'll need to run the following commands before booting a new kernel:
# fw_update # installboot sd0 The drivers still have some rough edges. I hope to iron those out in the coming weeks. Cheers, Mark
