Define missing VirtIO drivers necessary for AGLCooperate with IC-EG, IVI-EG and SAT to define which devices are necessary virtual AGL and assign priority.None

2-2
Design and implement missing VirtIO frontend driver of high priority devices for AGLBased on the priority defined in task 2-1, design and implement the high prioritized VirtIO frontend (including define virtio driver interface) Task 2-1

follow-up actions: propose the specification to OASIS and implementation to Linux Kernel


3
Design and implement VirtIO I/F complied device driver used in native environmentImplement reference physical device driver complied with VirtiO I/F defined in task 2-2 to extend VirtIO use to native environment (as a common device interface)Task 2-2

virtio-gpu 3D zero-copy

Avoid copying textures (other buffers?) between device VM and driver VM:

  • previous attempt was to eglimport textures from drivers VM
  • new attempt can be host allocation as crosvm is doing, but need to implement this in scope of pre-defined VRAM for security reasons
None

We would like to get Linaro & ARM's opinion whether to start discussion about Trustzone virtualization support in AGL (we would be grateful if you can take the lead of this activity)

7
Design and implement reference VirtIO backend on OSS HV (KVM or Xen) Implement backend for VirtIO devices selected in the task 2-1Task 2-2

Huge workload (may be not an appropriate for AGL Virt-EG's scope) => voluntary work in KVM & Xen community maybe better
