Unified extensible firmware interface (UEFI) capsule-based update of firmware logo image

1. A computing device, comprising:

one or more processors; and

at least one non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by the one or more processors, cause the computing device to:

receive, at a firmware logo image updater executing on the computing device, a Unified Extensible Firmware Interface (UEFI) capsule, the UEFI capsule comprising a firmware logo image;

store the UEFI capsule in a UEFI system partition of a non-volatile storage device to maintain the firmware logo image in the UEFI capsule during a first reboot of the computing device for display during a subsequent reboot of the computing device;

detect the first reboot of the computing device;

in response to detecting the first reboot of the computing device, execute a firmware comprising a logo update firmware management protocol (FMP);

retrieve, using the logo update FMP, the UEFI capsule stored in the UEFI system partition of the non-volatile storage device;

update, using the logo update FMP, a firmware logo image volume with the firmware logo image stored in the UEFI capsule to generate an updated firmware logo image; and

display, during the subsequent reboot of the computing device, the updated firmware logo image on a display screen connected to the computing device.

2. The computing device of claim 1 , wherein the firmware logo image volume is cryptographically signed separately from a remainder of the firmware comprising the firmware logo image volume.

3. The computing device of claim 1 , wherein the UEFI capsule further comprises a globally unique identifier (GUID) and wherein the firmware logo image updater is configured to authenticate the UEFI capsule based on the GUID.

4. The computing device of claim 1 , wherein the firmware logo image updater is configured to receive the UEFI capsule from a firmware update server.

5. A non-transitory computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by a computing device, cause the computing device to:

receive, at a firmware logo image updater executing on the computing device, a Unified Extensible Firmware Interface (UEFI) capsule, the UEFI capsule comprising a firmware logo image;

store the UEFI capsule in a UEFI system partition of a non-volatile storage device to maintain the firmware logo image in the UEFI capsule during a first reboot of the computing device for display during a subsequent reboot of the computing device;

detect the first reboot of the computing device;

in response to detecting the first reboot of the computing device, execute a firmware comprising a logo update firmware management protocol (FMP);

retrieve, using the logo update FMP, the UEFI capsule stored in the UEFI system partition of the non-volatile storage device;

update, using the logo update FMP, a firmware logo image volume with the firmware logo image stored in the UEFI capsule to generate an updated firmware logo image; and

display, during the subsequent reboot of the computing device, the updated firmware logo image on a display screen connected to the computing device.

6. The non-transitory computer-readable storage medium of claim 5 , wherein the firmware logo image volume is cryptographically signed separately from a remainder of the firmware comprising the firmware logo image volume.

7. The non-transitory computer-readable storage medium of claim 5 , wherein the UEFI capsule further comprises a globally unique identifier (GUID) and wherein the firmware logo image updater is configured to authenticate the UEFI capsule based on the GUID.

8. The non-transitory computer-readable storage medium of claim 5 , wherein the firmware logo image updater is configured to receive the UEFI capsule from a firmware update server.

9. A computer-implemented method, comprising:

receiving, at a firmware logo image updater executing on a computing device, a Unified Extensible Firmware Interface (UEFI) capsule, the UEFI capsule comprising a firmware logo image;

storing the UEFI capsule in a UEFI system partition of a non-volatile storage device to maintain the firmware logo image in the UEFI capsule during a first reboot of the computing device for display during a subsequent reboot of the computing device;

detecting the first reboot of the computing device;

in response to detecting the first reboot of the computing device, executing a firmware comprising a logo update firmware management protocol (FMP);

retrieving, using the logo update FMP, the UEFI capsule stored in the UEFI system partition of the non-volatile storage device:

updating, using the logo update FMP, a firmware logo image volume with the firmware logo image stored in the UEFI capsule to generate an updated firmware logo image; and

displaying, during the subsequent reboot of the computing device, the updated firmware logo image on a display screen connected to the computing device.

10. The non-transitory computer-readable storage medium of claim 9 , wherein the firmware logo image volume is cryptographically signed separately from a remainder of the firmware comprising the firmware logo image volume.

11. The non-transitory computer-readable storage medium of claim 9 , wherein the UEFI capsule further comprises a globally unique identifier (GUID) and wherein the firmware logo image updater is configured to authenticate the UEFI capsule based on the GUID.

12. The non-transitory computer-readable storage medium of claim 9 , wherein the firmware logo image updater is configured to receive the UEFI capsule from a firmware update server.
