Configuring hot-inserted device via management controller
An information handling system may include a processor, a basic input/output system (BIOS) configured to initialize the information handling system, and a management controller coupled to the processor and configured to provide out-of-band management of the information handling system. The BIOS may be configured to: subsequent to initialization of an operating system of the information handling system, receive a notification that an information handling resource has been hot-inserted into the information handling system; and delay processing of the information handling resource by the operating system until the management controller has performed a platform-specific configuration change to the information handling resource.
1. An information handling system comprising:
a processor;
a basic input/output system (BIOS) configured to initialize the information handling system; and
a management controller coupled to the processor and configured to provide out-of-band management of the information handling system;
wherein the BIOS is configured to:
subsequent to initialization of an operating system of the information handling system, receive a notification that an information handling resource has been hot-inserted into the information handling system, wherein the information handling resource is cryptographically protected; and
delay processing of the information handling resource by the operating system until the management controller has performed a platform-specific configuration change to the information handling resource that includes unlocking the information handling resource;
wherein the management controller is further configured to retrieve, from a remote information handling system, a cryptographic key usable to perform the unlocking.
2. The information handling system of claim 1 , wherein the BIOS is a Unified Extensible Firmware Interface (UEFI) BIOS.
3. The information handling system of claim 1 , wherein the information handling resource is a Peripheral Component Interconnect Express (PCIe) resource.
4. The information handling system of claim 1 , wherein the information handling resource is a storage resource.
5. The information handling system of claim 4 , wherein the storage resource is a Non-Volatile Memory Express (NVMe) storage resource having a storage controller included therein.
6. The information handling system of claim 5 , wherein the platform-specific configuration change includes changing a class code of the NVMe storage resource.
7. The information handling system of claim 1 , wherein the delaying includes delaying for a predetermined amount of time.
8. The information handling system of claim 1 , wherein the delaying includes delaying until the BIOS receives a system management interrupt from the management controller that the platform-specific configuration change has been completed.
9. An information handling system comprising:
a processor;
a basic input/output system (BIOS) configured to initialize the information handling system; and
a management controller coupled to the processor and configured to provide out-of-band management of the information handling system;
wherein the management controller is configured to:
subsequent to initialization of an operating system of the information handling system, receive a first notification that an information handling resource has been hot-inserted into the information handling system, wherein the information handling resource is cryptographically protected;
retrieve, from a remote information handling system, a cryptographic key usable to unlock the information handling resource;
perform a platform-specific configuration change to the information handling resource that includes unlocking the information handling resource; and
transmit a second notification to the operating system that the platform-specific configuration change has been completed.
10. The information handling system of claim 9 , wherein the BIOS is a Unified Extensible Firmware Interface (UEFI) BIOS.
11. The information handling system of claim 9 , wherein the information handling resource is a Peripheral Component Interconnect Express (PCIe) resource.
12. The information handling system of claim 9 , wherein the information handling resource is a storage resource.
13. The information handling system of claim 12 , wherein the storage resource is a Non-Volatile Memory Express (NVMe) storage resource having a storage controller included therein.
14. The information handling system of claim 13 , wherein the platform-specific configuration change includes changing a class code of the NVMe storage resource.
15. The information handling system of claim 13 , wherein the operating system is configured to initialize the NVMe storage resource prior to completion of the platform-specific configuration change, and wherein the NVMe storage resource is not usable for storage operations by the operating system until after the completion of the platform-specific configuration change.
16. The information handling system of claim 15 , wherein the second notification transmitted to the operating system comprises an asynchronous event request transmitted to a storage driver of the operating system.
