Page table stage 2 translation error
Posted: Wed Apr 24, 2019 1:18 am
Hello everyone,
I am using Erika v3 with Jailhouse as hypervisor. While trying to access a memory within Erika, i came across a problem. The error refers to a "fault on the stage 2 translation of an access for a stage 1 translation table walk.". So, the guest's page table is actually giving the fault. I want to find out how to retrieve the address of that table entry.
Another thing that i've noticed is that, even if i can access that memory, i cannot access another contiguous memory afterwards, as the system simply halts forever, while in Linux i can do it.
