class Smmu

Defined at line 44 of file ../../zircon/kernel/dev/iommu/arm_smmu/include/dev/arm_smmu/smmu.h

The implementation of an Iommu interface for an instance of an ARM SMMU

(version 2). Throughout this code, references (in the form of section and

table numbers) will be made to the public ARM documentation which can be

found in

"ARM System Memory Management Unit Architecture Specification"

"SMMU architecture version 2.0"

"ARM IHI 0062D.c (ID070116)"

zx::result<fbl::RefPtr<iommu::Iommu>> Create (const zbi_dcfg_arm_smmu_driver_t & config)

Create is used during kernel startup in order to create SMMU instances as

described to Zircon by the ZBI.

zx::result<fbl::RefPtr<iommu::Iommu>> Fetch (ktl::unique_ptr<const uint8_t[]> desc, size_t desc_len)

Fetch is used during zx_iommu_create syscalls. User mode is not allowed to

create arbitrary IOMMUs, they may only fetch references to instances which

were created during kernel startup.
