Device
DeviceSubRequest describes a request for device provided in the claim.spec.devices.requests[].firstAvailable array. Each is typically a request for a single resource like a device, but can also ask for several identical devices. DeviceSubRequest is similar to ExactDeviceRequest, but doesn't expose the AdminAccess field as that one is only supported when requesting a specific device.

AllocationMode and its related fields define how devices are allocated to satisfy this subrequest. Supported values are:
DeviceClassName references a specific DeviceClass, which can define additional configuration and selectors to be inherited by this subrequest. A class is required. Which classes are available depends on the cluster. Administrators may use this to restrict which devices may get requested by only installing classes with selectors for permitted devices. If users are free to request anything without restrictions, then administrators can create an empty DeviceClass for users to reference.
Selectors define criteria which must be satisfied by a specific device in order for that device to be considered for this subrequest. All selectors must be satisfied for a device to be considered.
If specified, the request's tolerations. Tolerations for NoSchedule are required to allocate a device which has a taint with that effect. The same applies to NoExecute. In addition, should any of the allocated devices get tainted with NoExecute after allocation and that effect is not tolerated, then all pods consuming the ResourceClaim get deleted to evict them. The scheduler will not let new pods reserve the claim while it has these tainted devices. Once all pods are evicted, the claim will get deallocated. The maximum number of tolerations is 16. This is an alpha field and requires enabling the DRADeviceTaints feature gate.
