Relaxed virtual memory in Armv8-A (extended version)

Autor: Simner, Ben, Armstrong, Alasdair, Pichon-Pharabod, Jean, Pulte, Christopher, Grisenthwaite, Richard, Sewell, Peter

Virtual memory is an essential mechanism for enforcing security boundaries, but its relaxed-memory concurrency semantics has not previously been investigated in detail. The concurrent systems code managing virtual memory has been left on an entirely

Architecture specifications such as Armv8-A and RISC-V are the ultimate foundation for software verification and the correctness criteria for hardware verification. They should define the allowed sequential and relaxed-memory concurrency behaviour of
