Constraints
You cannot perform memory tests while other tests that allocate and use memory within the region are performing. However,
you can perform the Read tests concurrently with other processes. You cannot run multiple memory tests at the same time as
they may collide within the memory spaces.
Memory tests cannot test all the memory, and without cache flushes, memory tests may not get out of the caches. The SDI
must ensure the memory accessed is accessing the physical memory. This check slows down the tests.
