Subject: [PATCH 0/3] migration dirty bitmap support ARMv7
Date: Mon, 14 Apr 2014 18:24:04 -0700 [thread overview]
Message-ID: <534C8A34.4090606@samsung.com> (raw)
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.

headers for migration dirtybitmap support
initial write protect of VM address space and on dirty log read
hooks to interface with QEMU for initial write protect, dirty log read
