Subject: [RFC PATCH v2 06/19] iommu: Pass struct iommu_iotlb_gather to ->unmap() and ->iotlb_sync()
Date: Thu, 11 Jul 2019 18:19:14 +0100 [thread overview]
Message-ID: <20190711171927.28803-7-will@kernel.org> (raw)
In-Reply-To: <20190711171927.28803-1-will@kernel.org>
To allow IOMMU drivers to batch up TLB flushing operations and postpone
them until ->iotlb_sync() is called, extend the prototypes for the
->unmap() and ->iotlb_sync() IOMMU ops callbacks to take a pointer to
the current iommu_iotlb_gather structure.
All affected IOMMU drivers are updated, but there should be no
functional change since the extra parameter is ignored for now.
