Subject: [PATCH v5 12/17] irqdomain: Add IRQ_DOMAIN_FLAG_MSI_REMAP value
Date: Wed, 4 Jan 2017 13:32:21 +0000 [thread overview]
Message-ID: <1483536746-2725-13-git-send-email-eric.auger@redhat.com> (raw)
In-Reply-To: <1483536746-2725-1-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.
