Computer scientist René Rebe has managed to pair a RISC-V processor with an off-the-shelf gaming GPU for the first time. Using the latest desktop-level development board from SiFive, the HiFive Unmatched, Rebe patched the Linux kernel to support an AMD Radeon RX 6700 XT. Although functionality is limited, the achievement is another milestone for the RISC-V architecture. It was recently rumored that Intel may have made an offer to purchase SiFive. This goes to show how the 64-bit platform has potential beyond microcontrollers or low-powered devices.
It took him ten hours to add support for the AMD Radeon RX 6700 XT graphics card and Mesa Gallium 21.1.5 driver to the Linux system. Not only allows Radeon RX 6700 XT to display Linux GUI, it even renders 3D graphics in hardware acceleration mode and decodes video. This is the first time someone has tried to use a RISC-V processor to work with a high-performance GPU, and it was quite successful.
