Two weeks ago AMD released an AMDGPU-PRO 17.40 driver intended for cryptocurrency mining systems while now that v17.40 series driver has been promoted to being their general purpose stable Linux hybrid driver...

Is huge page support dependent on something in Vega's hardware, or would it be possible on other GPUs?

[bridgman]

True huge page support depends on Vega hardware (it supports up-to-4-level page tables while previous HW is limited to 2-level) however Christian made changes to the fragment logic to improve behaviour on large-footprint apps with earlier HW as well.

The difference is nuanced - in both cases the idea is to allow one GPUVM TLB to cover a larger area of memory in order to reduce TLB thrashing - and won't make a lot of difference under normal use, but apps performing intensive random access across a footprint bigger than the TLBs can cover with small pages can show a useful improvement.
