[Qemu-devel] [PATCH v2 0/9] RCUification of the memory API, part 2 |

Tue, 3 Feb 2015 13:52:19 +0100 |
Part 2 converts ram_list to RCU. It is enough of a base for Stefan's
work on thread-safe migration bitmaps. TCG folks, please review.
Parts 3 (posted today) and 3.5 (to be done) will separate removal and
reclamation of device data. Part 4 will switch KVM MMIO and PIO to
unlocked lookup and convert a single device to unlocked access.
v1->v2: add comment in cpu_reload_memory_map [Fam]
do not remove ram_list mutex [Fam]

Mike Day (4):
rcu: introduce RCU-enabled QLIST
