Hi. Actually i want to know - why there is no GPU Swap support in Linux
based systems? It seems that the GPU works with graphical contexts in
the same fashion as CPU handle things. I mean there are page faults, GPU
have its own MMU, the memory used by GPU devices allocated via trivial
page_alloc mechanism. You would say that performance is a reason, but
there are some swap backends like zram: they use in-memory compression
instead of disk swapping. Moreover, i think there would be a GPU data
which could be swapped without significant drawbacks, because it
accessed very rare.
Thank you.
