Linux 5.8 Bringing Some Performance Boosts For AMD Renoir Graphics

Over the weekend I began running some benchmarks of the Linux 5.8 development kernel on the Lenovo Flex 5 laptop with Ryzen 5 4500U. One of the standouts so far for from this Linux 5.8 testing compared to the stable 5.6/5.7 kernel series is better Radeon graphics performance with the Renoir laptop.
