Subject: [RFC v4 11/16] irqdomain: Add IRQ_DOMAIN_FLAG_MSI_REMAP value
Date: Tue, 13 Dec 2016 20:30:29 +0000 [thread overview]
Message-ID: <1481661034-3088-12-git-send-email-eric.auger@redhat.com> (raw)
In-Reply-To: <1481661034-3088-1-git-send-email-eric.auger@redhat.com>
This new enum value aims at indicating whether the irq domain
implements MSI remapping. This property is useful to assess
the IRQ assignment safety at VFIO level.
