Linux Finally Breathes Life Into HD 7870 XT With AMDGPU Tweaks

Valve/Phoronix coverage notes that Timur Kristóf pushed patches to the AMDGPU driver to fix how harvested GCN 1.0 GPUs, like the Radeon HD 7870 XT (Tahiti LE), are handled by the Linux kernel. The updates address TCC cache configuration issues, enabling proper operation and out-of-the-box RADV Vulkan support for a card that historically didn’t work with open-source drivers, effectively reviving the HD 7870 XT on Linux nearly 14 years after its launch.
