Hi Anatoly,
I haven't looked through your patchset yet but quick question. As far as I
understand, currently EAL remaps virtual addresses to make VA layout matches PA
layout. I'm not sure my expression is 100% correct.
By your comment above, do you mean VA space for all available physical memory
will always be contiguous?
I have been curious about why VA space is fragmented in DPDK.
Thanks,
Yongseok
