(Possibly) stupid question:
Since, AIUI, the in-guest GPU driver is XenGT aware could it not allocate a
contiguous range of pages at start of day to use as GPU PTs? Or even just N
contiguous regions, e.g. i think the "8K" refers to pages, which is 16 2M
allocations, which is a far more manageable number of ranges to track than
8096 individual pages.
