This patch series primarily adds support for a new netlink ABI in the Intel On Demand driver for performing attestation of the hardware state. Attestation patches Patch 1: The attestation mailbox command requires that the message size register be set along with the package size. Adds that support. Patch 2: The attestation command will need to write the SPDM message and read the response. The current mailbox flow handles reads and writes separately. Combines the two flows. Patch 3: Patch 4 will create a separate c file for the netlink interface. Add a separate header file now. No functional changes. This mostly just makes it easier to see the changes in Patch 4. Patch 4: Adds attestation support to the driver and provides a netlink interface to perform the service. Other changes Patch 5: Adds support to read the in-band BIOS lock. If set, On Demand controls are not available in the driver. Patch 6: Adds a new attribute to allow reading the most current metering state. Patch 7: Fixes for the intel_sdsi tool Patch 8: Adds support to the intel_sdsi tool to read the current meter state. David E.
