| Contact: linux-coco@lists.linux.dev |
| Description: (RO) Report the number of remaining updates. TDX maintains a |
| log about each TDX module that has been loaded. This log has |
| a finite size, which limits the number of TDX module updates |
| that can be performed. |
| |
| After each successful update, the number reduces by one. Once it |
| reaches zero, further updates will fail until next reboot. The |
| number is always zero if the P-SEAMLDR doesn't support updates. |

| See Intel Trust Domain Extensions - SEAM Loader (SEAMLDR) |
| Interface Specification, Chapter "SEAMLDR_INFO" and Chapter |
| "SEAMLDR.INSTALL" for more information. |
