Hi,
In the seL4 FAQ section it states:
"Multicore is presently supported on x64 and Arm v7 (32-bit) and v8 (64-bit). Verification of the multicore kernel is in progress (but presently as an unfunded background activity)."
Considering only seL4 ----------------------------- My interpretation of this is that given a single seL4 application running on a device, it is not possible to currently guarantee the protections seL4 provides if the application invokes multiple threads across more than 1 core. Is this correct?
Considering CAmkES ---------------------------- I would also like to know how CAmkES affects this. For example, looking at the vm_multi app for the exynos5422 in the camkes-arm-vm repository, what would the effect be of assigning unique CPU affinities to each of the VM components? Do the guarantees still hold in this situation?
Thanks,
