Add policies for Atomic Display Framework · 7004789d

Greg Hackmann authored 11 years ago


ADF is a modern replacement for fbdev.

ADF's device nodes (/dev/adf[X]), interface nodes
(/dev/adf-interface[X].[Y]), and overlay engine nodes
(/dev/adf-overlay-engine[X].[Y]) are collectively used in similar
contexts as fbdev nodes.  Vendor HW composers (via SurfaceFlinger) and
healthd will need to send R/W ioctls to these nodes to prepare and
update the display.

Ordinary apps should not talk to ADF directly.
