[PATCH v3 -tip 0/5] kvm: Use rcuwait for vcpu blocking

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

 



The following is an updated revision of the kvm vcpu to rcuwait conversion[0],
following the work on completions using simple waitqueues.

Changes from v2:
  - new patch 3 which adds prepare_to_rcuwait and finish_rcu helpers.
  - fixed broken sleep and tracepoint semantics in patch 4. (Marc and Paolo)
  
This has only been run tested on x86 but compile tested on mips, powerpc
and arm32. 

This series applies on top of current -tip.
