* Tegra Hypervisor manager (tegra_hv)
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "nvidia,tegra-hv".
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- server-to-peers: Array of guest IDs of the peers this guest is server to.
|
||
|
|
Note that if you use loopbacks at least your guest ID should be included.
|
||
|
|
|
||
|
|
Required sub-node:
|
||
|
|
- queues: configuration about this guest
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- #address-cells: Should be <1>
|
||
|
|
- #size-cells: Should be <0>
|
||
|
|
|
||
|
|
Any other sub-nodes contain each ivc channel configuration; Properties
|
||
|
|
required are:
|
||
|
|
- reg: ID of the channel (single cell address)
|
||
|
|
- peers: Tupple of guest IDs this channel pertains to. If none of them is
|
||
|
|
the running guest's ID, then the ivc channel entry is ignored.
|
||
|
|
- nframes: Number of queue entries
|
||
|
|
- frame-size: Size of each frame in bytes. Note that it's good practice to
|
||
|
|
keep this aligned to 16.
|
||
|
