AMD --
AMD this week has quietly released an updated AMDGPU-PRO 17.40 hybrid driver targeting mining and GPGPU compute Linux customers.

The sole listed change with this AMDGPU-PRO 17.40 update is large page support for blockchain compute workloads. This is advertised as the "AMDGPU-PRO Beta Mining Driver 17.40" driver.

The release page mentions, "Introduces Large Page Support for Blockchain Compute Workloads. This driver is provided as a beta level support driver which should be considered "as is" and will not be supported with further updates, upgrades or bug fixes. This driver is not intended for graphics or gaming workloads."

While the driver has large page support, it requires also booting the kernel with e.g. "amdgpu.vm_fragment_size=9" for 2MB page support.

Those mining cryptocurrencies like Ethereum rely upon the AMDGPU-PRO driver when running on Radeon GPUs due to the newer ROCm OpenCL compute stack not yet fully working against upstream open-source components (e.g. the Linux kernel and LLVM) while the open-source Clover OpenCL stack isn't good enough for a majority of compute workloads. Hopefully in the months ahead ROCm will begin working on more upstream components.
