[PATCH 0/3] migration dirty bitmap support ARMv7

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch set supports migration dirty bitmap support implementation for
arm-kvm.  Spliting of pmd's to pte's as suggested is implemented on demand
when migration is started. 

I tested it on 4-way SMP ARMv7, with SMP guests.
2GB VMs with dirty shared memory segments upto 1.8 GB 
and relatively fast update rates 16Mb/5mS. 

Next course of action would be rmap support which 
scales much better on bigger systems. Although one
think that confused me, x86 migrations were sometimes
10 to 15 times slower, I think it must be something 
wrong with my configuration.
