Agenda
Discussion topics
CC/AJB: Had a chat about the various aspects of memory sharing
SS: 3 key areas to left
VirtIO with QEMU
need a smaller QEMU with just Xen and VirtIO at 50Kb instead of 20Mb
AJB: hopefully the single binary will help with that
Unprivileged VirtIO (i.e. limited memory view)
this is where QNX wins because it’s almost impossible to safety certify a Linux Dom0 vs QNX’s privileged micro-kernel model
multiple ways on doing this. Could Argo play a role
VM to VM comms
VirtIO is too complex and still not safety certifiable
Lack of hypervisor in OpenAMP could be a problem for Argo
AJB: should bring CC in next time we talk to @Bill Mills re OpenAMP
