Re: [RFC] How implement Secure Data Path ?

[Benjamin Gaignard]

I think now I have an answer to my question.

I will back come in a couple of weeks with a generic dmabuf allocator.
The feature set of this should be:
- allow to have per device specificone  allocator
- ioctl for buffer allocation and exporting dmabuf file descriptor on /dev/foo
- generic API to be able to call buffer securing module which is
platform specific.
- ioctl and kernel API to set/get dmabuf secure status

Sumit had already done a draft of this kind of dmabuf allocator with
his cenalloc [1]
I think I will start from that.
