Abstract
Examples relate to firmware-based provisioning of hardware resources. In some of the examples, firmware discovers and takes ownership of a hardware resource. At this stage, the firmware performs a test to verify the hardware resource. The firmware then assigns the hardware resource to an OS instance. At this stage, the firmware can suspend assigning further hardware resources to the OS instance in response to a satisfied notification from the OS instance.
Claims15
A system for firmware-based provisioning of hardware resources, comprising:
- a hardware resource;
- an OS instance operatively connected to the hardware resource;
- firmware operatively connected to the hardware resource, the firmware to:
- discover and take ownership of the hardware resource;
- perform a test to verify the hardware resource;
- assign the hardware resource to the OS instance;
- and
- in response to a release notification, add the hardware resource to a resource pool for allocation to other OS instances.
A method for firmware-based provisioning of hardware resources, comprising:
- discovering, by firmware, and taking ownership of a hardware resource;
- performing, by the firmware, a test to verify the hardware resource;
- assigning, by the firmware, the hardware resource to an OS instance of a plurality of OS instances;
- adding, by the firmware, the hardware resource to a resource pool for allocation to other OS instances in response to a release notification;
- and
- revoking, by the firmware, access to the hardware resource by the OS instance.
A non-transitory machine-readable storage medium encoded with instructions executable by a processor for firmware-based provisioning of hardware resources, the machine-readable storage medium comprising instructions to:
- discover, by firmware, and take ownership of a hardware resource;
- perform, by the firmware, a test to verify the hardware resource;
- assign, by the firmware, the hardware resource to an OS instance of a plurality of OS instances that are distributed across a plurality of server computing devices;
- and
- suspend, by the firmware, assigning further hardware resources to the OS instance in response to a satisfied notification from the OS instance.
