/**
* Flat instructions may resolve to the private segment (scratch),
* which is backed by main memory and provides per-lane scratch
* memory. Flat addressing uses apertures - registers that specify
* the address range in the VA space where LDS/private memory is
* mapped. The value of which is set by the kernel mode driver.
* These apertures use addresses that are not used by x86 CPUs.
* When the address of a Flat operation falls into one of the
* apertures, the Flat operation is redirected to either LDS or
* to the private memory segment.
*
* For private memory the SW runtime will allocate some space in
* the VA space for each AQL queue. The base address of which is
* stored in scalar registers per the AMD GPU ABI. The amd_queue_t
* scratch_backing_memory_location provides the base address in
* memory for the queue's private segment. Various other fields
* loaded into register state during kernel launch specify per-WF
* and per-work-item offsets so that individual lanes may access
* their private segment allocation.
*
* For more details about flat addressing see:
* http://rocm-documentation.readthedocs.io/en/latest/
