Hardware configuration reporting systems

One or more non-transitory machine readable media having instructions thereon which, in response to execution by one or more processing devices of an apparatus, cause the apparatus to:

• receive an indication of a request from arbiter logic, wherein:
• the one or more machine readable media is stored within an isolated memory to operate within a trusted execution environment (TEE) of a processing device, the processing device has the TEE and a non-trusted execution environment (non-TEE), and the arbiter logic is stored in the non-TEE, the processing device is to enter the TEE from the non-TEE in response to a particular interrupt, the TEE is executed from the isolated memory, the isolated memory is not accessible from the non-TEE, and the request represents a hardware configuration register;
• report an indicator of a value of the hardware configuration register represented by the request to the arbiter logic;
• and shut down hardware associated with the hardware configuration register based, at least in part, on the value of the hardware configuration register reported.

An apparatus for hardware configuration arbitration, comprising:

• arbiter logic to provide an indication of a request from an application to reporting logic of a TEE of a processing device, wherein:
• the processing device has the TEE and a non-TEE, the processing device is to enter the TEE from the non-TEE in response to a particular interrupt, the TEE is executed from an isolated memory not accessible from the non-TEE, the reporting logic is stored in the isolated memory, the arbiter logic is stored in the non-TEE, and the request represents a hardware configuration register;
• security logic to determine that an indicator, provided by the reporting logic in response to receipt of the indication of the request, of a value of the hardware configuration register represented by the request does not satisfy a stored security requirement;
• and
• action logic to shut down hardware associated with the hardware configuration register, at least in part in response to the determination that the stored security requirement is not satisfied.

One or more non-transitory machine readable media having instructions thereon which, in response to execution by one or more processing devices of an apparatus, cause the apparatus to:

• provide an indication of a request from an application to reporting logic of a trusted execution environment, TEE, of a processing device, wherein:
• the processing device has the TEE and a non-trusted execution environment, non-TEE,
• the application runs in the non-TEE,
• the processing device is to enter the TEE from the non-TEE in response to a particular interrupt,
• the TEE is executed from an isolated memory not accessible from the non-TEE,
• the reporting logic is stored in the isolated memory, and
• the request represents a hardware configuration register;
• determine that an indicator, provided by the reporting logic in response to receipt of the indication of the request, of a value of the hardware configuration register represented by the request does not satisfy a stored security requirement;
• and
• shut down hardware associated with the hardware configuration register at least in part in response to the determination that the stored security requirement is not satisfied.
