   PAL
      Platform Adaptation Layer

      PAL is the layer of Graphene that implements a narrow Drawbridge-like ABI
      interface (with function names starting with the `Dk` prefix)

      Whenever Graphene requires a service from the host platform (memory
      allocation, thread management and synchronization, file system and network
      stacks, etc.), it calls the corresponding PAL functionality. The PAL ABI
      is host-platform agnostic and is backed by the host-platform specific PAL,
      for example, the Linux-SGX PAL.

   SGX
      Software Guard Extensions is a set of instructions on Intel processors.
