Subject: [PATCH kernel v6 07/10] KVM: PPC: Pass kvm* to kvmppc_find_table()
Date: Thu, 2 Mar 2017 19:56:41 +1100 [thread overview]
Message-ID: <20170302085644.41828-8-aik@ozlabs.ru> (raw)
In-Reply-To: <20170302085644.41828-1-aik@ozlabs.ru>
The guest view TCE tables are per KVM anyway (not per VCPU) so pass kvm*
there. This will be used in the following patches where we will be
attaching VFIO containers to LIOBNs via ioctl() to KVM (rather than
to VCPU).
