Subject: [RFC/PATCH 21/22] KVM: s390: Add KVM HPAGE capability
Date: Mon, 6 Nov 2017 23:29:59 +0100 [thread overview]
Message-ID: <1510007400-42493-22-git-send-email-frankja@linux.vnet.ibm.com> (raw)
In-Reply-To: <1510007400-42493-1-git-send-email-frankja@linux.vnet.ibm.com>
KVM huge page backing support can not be easily tested under
s390. Currently testing is only possible after most of the guest has
already been set up.
To indicate, that KVM has huge page backing support, we add the
KVM_CAP_S390_HPAGE capability. This does not mean, that transparent
huge pages are supported.
