Subject: [PATCH v3 02/18] iommu/vt-d: Add DEV-MSI support
Date: Tue, 15 Sep 2020 16:27:49 -0700
Message-ID: <160021246905.67751.1674517279122764758.stgit@djiang5-desk3.ch.intel.com> (raw)
In-Reply-To: <160021207013.67751.8220471499908137671.stgit@djiang5-desk3.ch.intel.com>

From: Megha Dey <megha.dey@intel.com>

Add required support in the interrupt remapping driver for devices
which generate dev-msi interrupts and use the intel remapping
domain as the parent domain.
