Subject: [PATCH 0/5] Introduce device_iommu_maped() function
Date: Tue, 4 Dec 2018 18:24:59 +0100 [thread overview]
Message-ID: <20181204172504.19708-1-joro@8bytes.org> (raw)
Hi,
here is a patch-set to replace the dev->iommu_group checks
in the source tree by a proper function call. The pointer
checks mostly happen to check whether a device is managed my
an IOMMU. For that purpose a pointer check is not very
descriptable, so replace it by a function call that make its
purpose readable.
This also starts to remove direct access to the
dev->iommu_group pointer outside of iommu-code. This is
another move towards consolidating the various
iommu-related pointers in 'struct device' into one pointer
only.
Please review.
Thanks,
Joerg
