Subject: [PATCH v3 04/12] iommu/arm-smmu-v3: Enhance domain_alloc_user() to allocate PASID capable domain
Date: Thu, 17 Oct 2024 14:01:29 +0000 [thread overview]
Message-ID: <20241017140137.6028-5-vasant.hegde@amd.com> (raw)
In-Reply-To: <20241017140137.6028-1-vasant.hegde@amd.com>
Core layer is modified to call domain_alloc_user() to allocate PASID
capable domain. Enhance arm_smmu_domain_alloc_user() to allocate
PASID capable domain based on the 'flags' parameter.
