Another resource that is being set for an enclave is memory. User space memory regions, that need to be backed by contiguous memory regions, are associated with the enclave. One solution for allocating / reserving contiguous memory regions, that is used for integration, is hugetlbfs. The user space process that is associated with the enclave passes to the driver these memory regions. The enclave memory regions need to be from the same NUMA node as the enclave CPUs. Add ioctl command logic for setting user space memory region for an enclave. Signed-off-by: Alexandru Vasile <lexnv@xxxxxxxxxx> Signed-off-by: Andra Paraschiv <andraprs@xxxxxxxxxx>
