The length of the DMA window is given + by the third and fourth cells. + +Note that these are merely examples and real-world use-cases may use different +definitions to represent their individual needs. Always refer to the specific +IOMMU binding for the exact meaning of the cells that make up the specifier. + + +IOMMU master node: +================== + +Devices that access memory through an IOMMU are called masters. A device can +have multiple master interfaces (to one or more IOMMU devices). + +Required properties: +-------------------- +- iommus: A list of phandle and IOMMU specifier pairs that describe the IOMMU + master interfaces of the device. One entry in the list describes one master + interface of the device. + +When an "iommus" property is specified in a device tree node, the IOMMU will +be used for address translation. If a "dma-ranges" property exists in the +device's parent node it will be ignored. An exception to this rule is if the +referenced IOMMU is disabled, in which case the "dma-ranges" property of the +parent shall take effect. Note that merely disabling a device tree node does +not guarantee that the IOMMU is really disabled since the hardware may not +have a means to turn off translation. But it is invalid in such cases to +disable the IOMMU's device tree node in the first place because it would +prevent any driver from properly setting up the translations. + +Optional properties: +-------------------- +- pasid-num-bits: Some masters support multiple address spaces for DMA, by + tagging DMA transactions with an address space identifier. By default, + this is 0, which means that the device only has one address space. + +- dma-can-stall: When present, the master can wait for a transaction to + complete for an indefinite amount of time. Upon translation fault some + IOMMUs, instead of aborting the translation immediately, may first + notify the driver and keep the transaction in flight. This allows the OS + to inspect the fault and, for example, make physical pages resident + before updating the mappings and completing the transaction. Such IOMMU + accepts a limited number of simultaneous stalled transactions before + having to either put back-pressure on the master, or abort new faulting + transactions. + + Firmware has to opt-in stalling, because most buses and masters don't + support it. In particular it isn't compatible with PCI, where + transactions have to complete before a time limit. More generally it + won't work in systems and masters that haven't been designed for + stalling. For example the OS, in order to handle a stalled transaction, + may attempt to retrieve pages from secondary storage in a stalled + domain, leading to a deadlock. + + +Notes: +====== + +One possible extension to the above is to use an "iommus" property along with +a "dma-ranges" property in a bus device node (such as PCI host bridges). This +can be useful to describe how children on the bus relate to the IOMMU if they +are not explicitly listed in the device tree (e.g. PCI devices). However, the +requirements of that use-case haven't been fully determined yet. Implementing +this is therefore not recommended without further discussion and extension of +this binding. + + +Examples: +========= + +Single-master IOMMU: +-------------------- + + iommu { + #iommu-cells = <0>; + }; + + master { + iommus = <&{/iommu}>; + }; + +Multiple-master IOMMU with fixed associations: +---------------------------------------------- + + /* multiple-master IOMMU */ + iommu { + /* + * Masters are statically associated with this IOMMU and share + * the same address translations because the IOMMU does not + * have sufficient information to distinguish between masters. + * + * Consequently address translation is always on or off for + * all masters at any given point in time. + */ + #iommu-cells = <0>; + }; + + /* static association with IOMMU */ + master@1 { + reg = <1>; + iommus = <&{/iommu}>; + }; + + /* static association with IOMMU */ + master@2 { + reg = <2>; + iommus = <&{/iommu}>; + }; + +Multiple-master IOMMU: +---------------------- + + iommu { + /* the specifier represents the ID of the master */ + #iommu-cells = <1>; + }; + + master@1 { + /* device has master ID 42 in the IOMMU */ + iommus = <&{/iommu} 42>; + }; + + master@2 { + /* device has master IDs 23 and 24 in the IOMMU */ + iommus = <&{/iommu} 23>, <&{/iommu} 24>; + }; + +Multiple-master IOMMU with configurable DMA window: +--------------------------------------------------- + + / { + iommu { + /* + * One cell for the master ID and one cell for the + * address of the DMA window.
