Trying Out AMDGPU DRM-Next Ahead Of Linux 4.20~5.0
In most of the OpenGL Linux gaming tests, there weren't any performance changes to note with the kernels tested.
Total War: Thrones of Britannia with the Radeon RX Vega 64 sees a nice performance improvement with DRM-Next ahead of Linux 4.20~5.0.
The VKMark performance also saw a large improvement with DRM-Next on the RX Vega 64... Granted this is just a synthetic Vulkan test at least now the Vega GPU is performing much faster than the Polaris card.
The most likely explanation in the few tests seeing performance improvements on DRM-Next is thanks to the GPUVM optimizations merged this cycle, but there were also the seemingly never-ending power management tuning and other work too. Regardless, the next kernel cycle is looking to be a big one for open-source Radeon users given all the ongoing feature work.
