Subject: [Xen-devel] [PATCH v2 0/4] x86/nvmx: fixes for interrupt injection
Date: Wed, 25 Mar 2020 11:19:06 +0100
Message-ID: <20200325101910.29168-1-roger.pau@citrix.com> (raw)

Hello,

osstest identified a regression caused by my earlier attempt to fix
interrupt injection when using nested VMX. This series aims to fix the
regression, and should unblock several osstest branches.

The following report is from osstest with this series applied:

http://logs.test-lab.xenproject.org/osstest/logs/148979/

Note the last patch (4/4) is the one that actually fixes the issue. Xen
will always use the Ack on exit feature so patches 2/4 and 3/4 don't
change the functionality when running a nested Xen, as it always
requires SVI to be updated.

Thanks, Roger.
