Information handling system with mechanism for reporting status of persistent memory firmware update
During a power-on self-test (POST), a basic input/output system (BIOS) retrieves an attribute value associated with the persistent memory device, and compares the attribute value to a default value. In response to the attribute value matching the default value, the BIOS may determine that a firmware management protocol was not executed during a previous POST. In response to the attribute value not matching the default value, the BIOS may compare the attribute value to a current firmware version of firmware within the persistent memory device.
1. A method comprising:
beginning, by a basic input/output system (BIOS), a power-on self-test (POST) of an information handling system; and
during the POST:
retrieving an attribute value associated with a persistent memory device;
comparing the attribute value to a default value;
in response to the attribute value matching the default value, determining that a firmware management protocol was not executed during a previous POST;
in response to the attribute value not matching the default value, comparing the attribute value to a current firmware version of firmware within the persistent memory device; and
in response to the attribute value matching the current firmware version, logging a firmware update successful message.
2. The method of claim 1 , further comprising:
during a previous POST:
executing a routine to stage a firmware update image for the persistent memory device in a memory controller of the information handling system;
determining whether the routine is successful; and
in response to the routine being successful, setting the attribute value to a staged firmware version, wherein the staged firmware version is associated with the firmware update image stored within the memory controller.
3. The method of claim 2 , further comprising:
during the previous POST:
in response to the routine not being successful, setting the attribute value to a pre-defined error code.
4. The method of claim 1 , further comprising:
providing the firmware update successful message on a display device of the information handling system, the firmware update successful message indicating that firmware of the persistent memory device was successfully updated.
5. The method of claim 1 , further comprising:
in response to the attribute value not matching the current firmware version, logging a firmware update failure message.
6. The method of claim 1 , further comprising:
detecting a cold reset of the information handling system prior to beginning the POST.
7. The method of claim 1 , wherein the persistent memory device is a persistent dual in-line memory module.
8. The method of claim 1 , wherein the attribute value is stored in a BIOS non-volatile random access memory.
9. An information handling system comprising:
a persistent memory device;
a memory controller to communicate with the persistent memory device; and
a basic input/output system (BIOS) that during a power-on self-test (POST) of the information handling system: retrieves an attribute value associated with the persistent memory device; compares the attribute value to a default value; in response to the attribute value matching the default value, determines that a firmware management protocol was not executed during a previous POST; in response to the attribute value not matching the default value, compares the attribute value to a current firmware version of firmware within the persistent memory device; and in response to the attribute value matching the current firmware version, logs a firmware update successful message.
10. The information handling system of claim 9 , wherein during a previous POST, the BIOS executes a routine to stage a firmware update image for the persistent memory device in the memory controller of the information handling system; determines whether the routine is successful; and in response to the routine being successful, sets the attribute value to a staged firmware version, wherein the staged firmware version is associated with the firmware update image stored within the memory controller.
11. The information handling system of claim 10 , wherein during the previous POST, the BIOS in response to the routine not being successful sets the attribute value to a pre-defined error code.
12. The information handling system of claim 9 , wherein the BIOS provides the firmware update successful message on a display device of the information handling system, the firmware update successful message indicating that firmware of the persistent memory device was successfully updated.
13. The information handling system of claim 9 , wherein the BIOS logs a firmware update failure message in response to the attribute value not matching the current firmware version.
14. The information handling system of claim 9 , wherein the BIOS detects a cold reset of the information handling system prior to beginning the POST.
15. The information handling system of claim 9 , wherein the persistent memory device is a persistent dual in-line memory module.
16. The information handling system of claim 9 , wherein the attribute value is stored in a BIOS non-volatile random access memory (NVRAM).
17. A method comprising:
setting an attribute value to a default value, the attribute value being associated with a persistent memory device of an information handling system;
executing a routine to stage a firmware update image for the persistent memory device in a memory controller of the information handling system;
determining whether the routine was successful;
in response to the routine being successful, setting the attribute value to a staged firmware version, wherein the staged firmware version is associated with the firmware update image stored within the memory controller;
detecting a cold reset of the information handling system;
after the cold reset of the information handling system, beginning, by a basic input/output system (BIOS), a power-on self-test (POST) of the information handling system; and
during the POST:
retrieving the attribute value;
comparing the attribute value to a default value;
in response to the attribute value matching the default value, determining that a firmware management protocol was not executed during a previous POST;
in response to the attribute value not matching the default value, comparing the attribute value to a current firmware version of firmware within the persistent memory device; and
in response to the attribute value matching the current firmware version, logging a firmware update successful message.
18. The method of claim 17 , further comprising:
providing the firmware update successful message on a display device of the information handling system, the firmware update successful message indicating that firmware of the persistent memory device was successfully updated.
19. The method of claim 17 , wherein the persistent memory device is a persistent dual in-line memory module.
20. The method of claim 17 , wherein the attribute value is stored in a BIOS non-volatile random access memory.
