Linux 6.19's Significant ~30% Performance Boost For Old AMD Radeon GPUs

It took no time at all to find the AMDGPU kernel driver providing immediate and significant performance benefits over the Radeon driver default. The Radeon driver doesn't see too much new feature activity in recent years and just continues existing and seeing seldom fixes and maintenance work within the mainline kernel. Running this GCN 1.0 Southern Islands graphics card on the AMDGPU driver provided a very nice performance gain for this aging graphics card.
With the same RadeonSI Gallium3D driver and simply moving to Linux 6.19 with AMDGPU by default can provide some meaningful performance gains for those still using the Radeon HD 7000 series and similar GCN 1.0/1.1 graphics processors.
