[Xen-devel] Granting huge memory regions?

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

Hey,

for some research we are currently looking into mapping big memory 
regions to PV guests. With big I mean 100s to 1000s of mega bytes. Using 
one grant for each 4K page seems to be expensive although we got it 
working so far.
Is there another mechanism we could look into? Is changing the 
granularity to huge pages promising? What would we need to do roughly to 
support it?
Thanks,

Simon
