From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eric Auger Subject: [RFC v8 2/7] KVM: Add devid in kvm_kernel_irq_routing_entry Date: Fri, 22 Jul 2016 13:46:35 +0000 Message-ID: <1469195200-6498-3-git-send-email-eric.auger@redhat.com> References: <1469195200-6498-1-git-send-email-eric.auger@redhat.com> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: QUOTED-PRINTABLE Return-path: In-Reply-To: <1469195200-6498-1-git-send-email-eric.auger@redhat.com> Sender: kvm-owner@vger.kernel.org To: eric.auger@redhat.com, eric.auger.pro@gmail.com, marc.zyngier@arm.com, christoffer.dall@linaro.org, andre.przywara@arm.com Cc: drjones@redhat.com, kvmarm@lists.cs.columbia.edu, kvm@vger.kernel.org, pbonzini@redhat.com, rkrcmar@redhat.com List-Id: kvmarm@lists.cs.columbia.edu Enhance kvm_kernel_irq_routing_entry to transport the device id field, devid. A new flags field makes possible to indicate the devid is valid. Those additions are used for ARM GICv3 ITS MSI injection. The original struct msi_msg msi field is replaced by a new custom structure that embeds the new fields.
