Subject: [PATCH 0/2] iommu/amd: Correctly Align Multiple MSI IRQs
Date: Fri,  6 Oct 2017 13:34:10 +0200	[thread overview]
Message-ID: <1507289652-30166-1-git-send-email-joro@8bytes.org> (raw)

Hi,

Thomas made me recently aware of the fact that the IRQ
remapping code in the AMD IOMMU driver does not enforce the
required alignment of IRQ indexes for multiple MSI IRQs.

This patch-set adds the correct alignment for these IRQs.

Regards,

	Joerg
