Hi This project is what I have been looking for (secure boot + watchdog), but I have a hard time grasping why it works.
The UEFI spec states[1]: "The watchdog timer is only used during boot services. On successful completion of EFI_BOOT_SERVICES.ExitBootServices() the watchdog timer is disabled." So the boot looke something like this (AFAIU): 1. efibootguard starts 2. efibootguard initializes the watchdog 3. LoadImage() 4. StartImage() 5. Linux starts and calls ExitBootServices() Why isn't UEFI disabling the watchdog initialized by efibootguard when ExitBootServices() is called? [1] UEFI Spec 2.6, EFI_BOOT_SERVICES.SetWatchdogTimer(): Best regards Kristian Klausen -- You received this message because you are subscribed to the Google Groups "EFI Boot Guard" group.
