Hi,
According to Takahiro's suggestion and discussion, I made a patchset to
update the EFI capsule-on-disk, so that it does not use UpdateCapsule()
EFI API and reset after completing the capsule-on-disk.
The reset after completing the capsule-on-disk is stated in the UEFI
specification 2.9, section 8.5.5 "Delivery of Capsules via file on Mass
Storage device" as below,
In all cases that a capsule is identified for processing the system is
restarted after capsule processing is completed.
Note that this feature is enabled by CONFIG_EFI_RESET_AFTER_CAPSULE_ON_DISK.
If you want to keep the current firmware runs after capsule-on-disk (e.g.
for debugging), you can configure it disabled.
Thank you,
