AMD Readies "New Stuff" For Linux 6.6 Graphics Driver, AMDGPU DC For RISC-V
This is a big pull request of lots of AMDGPU/AMDKFD driver updates from working on more Instinct MI300 accelerator series bits to RDNA3 GPU fixes and other random improvements across the board. The pull request was simply summed up as "new stuff" for this cycle without any single, super-exciting feature added. Some readers though will be excited by the aspect of being able to build AMDGPU Display Code (DC) on RISC-V for AMD Radeon graphics display support with recent GPUs on RISC-V boards that have PCIe slots. Due to the floating point code and other bits within the DC space, the open-source AMDGPU driver hasn't always played well with non-x86_64 architectures that are less well tested by the developers. In any event like the work seen with AMDGPU on POWER9 and AArch64, it's good seeing DC building now on RISC-V.
