Subject: [PATCH 4/6] hw/i386/intel_iommu: Fix index calculation in vtd_interrupt_remap_msi()
Date: Wed, 2 Aug 2023 15:57:21 +0200 [thread overview]
Message-ID: <20230802135723.178083-5-thuth@redhat.com> (raw)
In-Reply-To: <20230802135723.178083-1-thuth@redhat.com>
The values in "addr" are populated locally in this function in host
endian byte order, so we must not swap the index_l field here.
