FreeBSD lacks video acceleration for Broadcom's VideoCore hardware which is on
ARM64 architecture, which is for Raspberry Pi's, BeagleBoards and other Small
Board Computers (SBC's). For reference, SBC's don't use Radeon, Intel and
Nvidia GPU's.

NetBSD has 2D drivers which works for VideoCoreIV and VideoCoreVI. FreeBSD
needs to import that, and be aware of the lack of 3D acceleration on it.

VC4 is the driver which handles 2D acceleration on both VideoCoreIV and
VideoCoreVI. VC4 also handles 3D acceleration for only VideoCoreIV. V3D handles
3D acceleration only for VideoCoreVI. These drivers come from the Raspberry Pi
project. NetBSD has imported the VC4 driver.

https://pkgsrc.se/misc/raspberrypi-userland isn't the kernel modules, but it's
from their ports system of programs which use VideoCore drivers.

Thank you!
