Subject: [patch 05/12] [PATCH] kvm-s390-ucontrol: disable in-kernel handling of SIE intercepts
Date: Thu, 01 Dec 2011 13:57:37 +0100 [thread overview]
Message-ID: <20111201130409.329920141@de.ibm.com> (raw)
In-Reply-To: 20111201125732.085553111@de.ibm.com
[-- Attachment #1: no-sie-intercepts-for-ucontrol.patch --]
[-- Type: text/plain, Size: 823 bytes --]
This patch disables in-kernel handling of SIE intercepts for user
controlled virtual machines. All intercepts are passed to userspace
via KVM_EXIT_SIE exit reason just like SIE intercepts that cannot be
handled in-kernel for regular KVM guests.
