[edk2] [PATCH] MdeModulePkg CapsuleApp: Add -NR (no-reset) option support
Posted by Star Zeng 7 years ago
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=388

Add -NR (no-reset) option support, once the option is specified,
no reset will be trigger for the capsule with flag
CAPSULE_FLAGS_PERSIST_ACROSS_RESET and no CAPSULE_FLAGS_INITIATE_RESET.

Posted by Yao, Jiewen 7 years ago
I feel a little confused on "but no CAPSULE_FLAGS_INITIATE_RESET".

> +  Print(L"  -NR: No reset will be trigger for the capsule with flag\n");
> +  Print(L"       CAPSULE_FLAGS_PERSIST_ACROSS_RESET but no CAPSULE_FLAGS_INITIATE_RESET.\n");


Do you mean "No impact to CAPSULE_FLAGS_INITIATE_RESET", because this flag is consumed by Capsule driver, but not this APP?

If so, we can update the help info to make it clear?

Posted by Zeng, Star 7 years ago
Yes, right.

How about to like below?

  Print(L"  -NR: No reset will be triggered for the capsule\n");
  Print(L"       with CAPSULE_FLAGS_PERSIST_ACROSS_RESET and without CAPSULE_FLAGS_INITIATE_RESET.\n");

Thanks,
Star
