Glad to see this happen. :)
After this patch landed, some code pieces in i915 which are specifically
for disabling dynamic PDP update via LRIs under 32 bit PPGTT could also
be removed.
For example, gen8_preallocate_top_level_pdp() in i915_gem_gtt.c
Thanks,
Zhi.

Configurations like virtualized environments may support only 48 bit
ppGTT without supporting 32 bit ppGTT. Support this by disconnecting
the relationship of the two feature bits.
Did the gvt patches land in dinq? After that, I say we just kill the
module parameter, and so make the choice of GTT mode much easier to follow.
Have we ever asked a user to debug a problem by changing GTT modes in
the last 5 years?
