◆ resolveFlatSegment()
| void gem5::GPUDynInst::resolveFlatSegment | ( | const VectorMask & | mask | ) |
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/ ROCm_Compiler_SDK/ROCm-Native-ISA.html#flat-scratch
