[PATCH 00/22] [uq/master] Patch queue, part II

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

 



This second round of patches focus on issues in cpus.c, primarily signal
related. The highlights are

 - Add missing KVM_RUN continuation after I/O exits
 - Fix for timer signal race in KVM entry code under !CONFIG_IOTHREAD
   (based on Stefan's findings)
 - MCE signal processing under !CONFIG_IOTHREAD
 - Prevent abortion on multiple VCPU kicks
 - Fixed synchronous (ie. VCPU-issued) reset request processing

Topics remaining for a third round are cleanups and refactorings of the
KVM VCPU entry/exit path, MCE rework, and a few assorted cleanups. But I
will wait at least until these bits here are ready for an upstream
merge.
