NVIDIA Unlocks GPU System Processor (GSP) for Improved System Performance
In 2016, NVIDIA announced that the company is working on replacing its Fast Logic Controller processor codenamed Falcon with a new GPU System Processor (GSP) solution based on RISC-V Instruction Set Architecture (ISA). This novel RISC-V processor is codenamed NV-RISCV and has been used for an unknown period as GPU's controller core, coordinating everything in the massive pool of GPU cores. Today, NVIDIA has decided to open this NV-RISCV CPU to a broader spectrum of applications starting with 510.39 drivers. According to the NVIDIA documents, this is only available in the select GPUs for now, mainly data-centric Tesla accelerators.NVIDIA DocumentsSome GPUs include a GPU System Processor (GSP) which can be used to offload GPU initialization and management tasks. This processor is driven by the firmware file /lib/firmware/nvidia/510.39.01/gsp.bin. A few select products currently use GSP by default, and more products will take advantage of GSP in future driver releases.
Offloading tasks which were traditionally performed by the driver on the CPU can improve performance due to lower latency access to GPU hardware internals.
