[Xen-devel] [PATCH 0 of 4] Mem event handling improvements

[Andres Lagar-Cavilla <andres@xxxxxxxxxxxxxxxx>]

Several improvements to the mem event interface are included in this 
series. Most notably:

- The ability to trigger resume actions in the hypervisor via an
  event channel kick, as opposed to a domctl. Less locking and more
  batching.

- Improvements to the management of the mem event ring. Improvements 
  on return codes, vcpu pause semantics, and handling of corner 
  cases.
