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.
