Subject: [PATCH 6/7] KVM: nSVM: do not reload pause filter fields from VMCB
Date: Fri, 15 May 2020 13:41:43 -0400 [thread overview]
Message-ID: <20200515174144.1727-7-pbonzini@redhat.com> (raw)
In-Reply-To: <20200515174144.1727-1-pbonzini@redhat.com>
These fields do not change from VMRUN to VMEXIT; there is no need
to reload them on nested VMEXIT.
