Last week I wrote about the interesting HIPSPV back-end for LLVM to take AMD HIP code -- which generally starts off as NVIDIA CUDA code to begin with before the HIP-ification -- and to be able to output that from the LLVM compiler stack as the SPIR-V intermediate representation used across OpenCL and Vulkan drivers. The goal with this is to be able to take AMD HIP code and ultimately be able to run it on Intel graphics processors but potentially other vendors/drivers too given the vendor-neutral SPIR-V. More of that HIPSPV work is now hitting mainline LLVM...

With Linux 5.17 FUSE is expanding the DAX support to allow per-inode control as well...
