Review request for Default. Repository: gem5 Description ------- Changeset 11683:e48e281afdd8 --------------------------- gpu-compute: support in-order data delivery in GM pipe this patch adds an ordered response buffer to the GM pipeline to ensure in-order data delivery. the buffer is implemented as a stl ordered map, which sorts the request in program order by using their sequence ID. when requests return to the GM pipeline they are marked as done. only the oldest request may be serviced from the ordered buffer, and only if is marked as done. the FIFO response buffers are kept and used in OoO delivery mode Diffs ----- src/gpu-compute/GPU.py 220fa4099b9a91526b8a1828f27cf1a9f3c15837 src/gpu-compute/compute_unit.cc 220fa4099b9a91526b8a1828f27cf1a9f3c15837 src/gpu-compute/global_memory_pipeline.hh 220fa4099b9a91526b8a1828f27cf1a9f3c15837 src/gpu-compute/global_memory_pipeline.cc 220fa4099b9a91526b8a1828f27cf1a9f3c15837 configs/example/apu_se.py 220fa4099b9a91526b8a1828f27cf1a9f3c15837 src/arch/hsail/insts/decl.hh 220fa4099b9a91526b8a1828f27cf1a9f3c15837 src/arch/hsail/insts/mem_impl.hh 220fa4099b9a91526b8a1828f27cf1a9f3c15837 src/arch/hsail/insts/pseudo_inst.cc 220fa4099b9a91526b8a1828f27cf1a9f3c15837 Diff: http://reviews.gem5.org/r/3658/diff/ Testing ------- Thanks, Tony Gutierrez _______________________________________________ gem5-dev mailing list [email protected] http://m5sim.org/mailman/listinfo/gem5-dev
