[Qemu-devel] [PATCH v1 0/6] make memory listener prepared for rcu style

[Liu Ping Fan]

From: Liu Ping Fan <address@hidden>

This series aim to make mmio dispatch lockless.

Based on Paolo's tree git://github.com/bonzini/qemu.git, branch iommu
For seqlock and rcu, I think Paolo will post them out later.

rfcv1->v1:
  use seqlock to protect reader against writer (thanks to Paolo's suggestion)
  concenter the root of each AddressSpaceDispatch to ease switching to next

Liu Ping Fan (6):
  mem: change variable to macro
  mem: make global dispatch table ready for rcu
  mem: fold tcg listener's logic into core memory listener
  mem: concenter the root of each AddressSpaceDispatch
  mem: make dispatch path satify rcu style
  mem: change tcg code to rcu style
