Abstract

See full text

Embodiments herein describe partitioning an acceleration device based on the needs of each user application executing in a host. In one embodiment, a flexible queue provisioning method allows the acceleration device to be dynamically partitioned by pushing the configuration through a control command queue to the device by management software running in a trusted zone. The new configuration is parsed and verified by trusted firmware, which, then, creates isolated IO command queues on the acceleration device. These IO command queues can be directly mapped to a user application, VM, or other PCIe devices. In one embodiment, each IO command queue exposes only the compute resource assigned by the trusted firmware in the acceleration device.
