Rob,

It is certainly analogous to the DRM access control interfaces, and I would expect that access to memory objects from the graphics stack would go through those interfaces (i.e. Xorg/EGL calls libdrm, calls DRM kernel ioctl, calls memory manger inside the kernel), but we need to make sure we have equivalent interfaces setup for non-graphics applications to make sure that all access control policy is honored.  So, in short, yes, there's a connection :-).

cheers,
Jesse

btw, the access control aspect of this sort of reminds me of the DRM
driver infrastructure, and authentication between direct rendering
client and x-server (or whoever the DRM master is)..

I wonder if there is, or should be, a connection..
