Subject: [Qemu-devel] [PATCH v2 0/2] mttcg: Handle exception and flags in atomic execution
Date: Fri, 10 Feb 2017 13:45:23 -0500	[thread overview]
Message-ID: <20170210184525.10966-1-bobby.prani@gmail.com> (raw)

The previous version, though ideal, needs more work to enable calling
start_exclusive() from cpu_exec() and also does not properly handle
exception from atomic context. Exceptions in atomic context will not
call exclusive_end() and would go to the outer most loop causing a deadlock.

The following patches allow proper handling of flags set and
exceptions from the atomic exectuion context.

Alex, please fold/squash them as you feel necessary.

Pranith Kumar (2):
  tcg: Save cpu flags in atomic execution
  tcg: Set jmp_env to handle exceptions from atomic execution
