Hello Takahiro
when I select EFI_CAPSULE_ON_DISK_EARLY this implies EFI_SETUP_EARLY.
With EFI_SETUP_EARLY I cannot use PREBOOT to add a disk via the host command. So I do not see how the feature could be tested on the sandbox.
I have noticed this issue. In sandbox test case, a disk will be attached via "host bind" command, and so EFI_SETUP_EARLY is simply unusable. Instead, the trick is that the current python script performs
if not capsule_early: # need to run uefi command to initiate capsule handling output = u_boot_console.run_command( 'env print -e -all Capsule0000')
after rebooting U-Boot. So at least temporarily you have to turn off EFI_CAPSULE_ON_DISK_EARLY, and do the similar thing in PREBOOT.
I think we will have to enable dynamic binding of block devices to overcome this mutual blocking of features.
I'm not sure yet how the scenario looks like here, but as far as "dynamic binding" is concerned, I have submitted the patch of this exact feature to support plug-in/removable devices (like usb stick and cd-rom) more than two years ago. https://lists.denx.de/pipermail/u-boot/2018-November/346740.html
What are your ideas?
Or simply, we'd better move efi_obj_list_init() backward just before efi_launch_capsules() in main_loop() if it is feasible.
