Providing a partial reconfiguration (PR) bitstream to a cloud service provider for PR configuration of an accelerator device

A method comprising:

• verifying, by one or more processors, a base bitstream of an accelerator device, the base bitstream published by a cloud service provider (CSP);
• generating a partial reconfiguration (PR) bitstream based on the base bitstream, the PR bitstream to fit within at least one PR region of PR boundary setups of the accelerator device;
• inspecting accelerator device attestation received from a secure device manager (SDM) of the accelerator device;
• and
• responsive to successful inspection of the accelerator device attestation, providing the PR bitstream to the CSP for PR reconfiguration of the accelerator device.

A non-transitory machine readable storage medium comprising instructions that, when executed, cause at least one processor to at least:

• verify, by the at least one processor, a base bitstream of an accelerator device, the base bitstream published by a cloud service provider (CSP);
• generate a partial reconfiguration (PR) bitstream based on the base bitstream, the PR bitstream to fit within at least one PR region of PR boundary setups of the accelerator device;
• inspect accelerator device attestation received from a secure device manager (SDM) of the accelerator device;
• and
• responsive to successful inspection of the accelerator device attestation, provide the PR bitstream to the CSP for PR reconfiguration of the accelerator device.
