[PATCH 0/8] Intel On Demand: Add netlink interface for SPDM attestation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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

Patch 7: Fixes for the intel_sdsi tool

Patch 8: Adds support to the intel_sdsi tool to read the current meter
