Is there any documentation describing the usage of empty capsule to set
the image acceptance state?
I actually don't know about documentation. I was talking to Ilias to make
sure that documentation is up2date because there are missing couple of
things there.
Sughosh should have more to say here about A/B update.
I am testing A/B update and if you setup oemflags to 0x8000 then capsules
are not automatically accepted and waiting for acceptance capsule to be
passed.
When I tested it I found out that they are not process that's why I created
this patch.
The path you tried to modify is only executed by "efidebug capsule update"
or more specifically via the runtime service, UPDATE_CAPSULE.
But this API is NOT officially supported in the current capsule implementation
(at least, in my initial intention).
The only way to invoke capsule updates is to reboot the system.
If you want to test A/B update, please do the reboot.
I realized that to get full flow you need to use capsule update on disk to get
all functionalities. But it is very impractical. Actually I would expect via
efidebug you should be able to perform all steps as capsule update performs when
you do reboot.
I would also understand that via efidebug you are not able to apply any capsule
but I don't think it is right that you can apply just update capsules but not
empty capsules. I would understand none or all but not something in the middle.
The A/B update functionality requires using the capsule-on-disk
functionality for performing the updates. This is also mentioned in
the fwu_updates.rst document. You should be able to apply empty
capsules even with the 'efidebug disk-update' command.
Yes this is working fine.
ZynqMP> efidebug capsule disk-update
#####
Applying capsule capsule1.bin succeeded.

Applying capsule capsule2.bin succeeded.
Reboot after firmware update.
I tested it also with empty capsules which are also process properly.
I have never
used the 'efidebug capsule update' command, so I'm not sure if that is
supported. Like Takahiro mentioned, if you place the capsules(genuine
or empty) under the /EFI/UpdateCapsule/ directory, the update should
happen automatically, since the fwu update feature also enables the
EFI_CAPSULE_ON_DISK_EARLY config.
Yes that's work fine on production systems.
But from my point of view there shouldn't be really a problem to also apply
empty capsule via efidebug capsule update to be able to see that steps and
changes in mdata structure without performing reset.
Again I have no issue with code which is using capsule-on-disk feature but I
think that pretty much all these steps which are done automatically should be
possible to do through steps to see them. That's what you can do with bootm
start and simply stepping through it.
I am testing 2 images per bank and I can simply load other partition by simple
commands
tftpboot 0x100000 192.168.0.105:capsule1.bin && efidebug capsule update -v
0x100000
tftpboot 0x100000 192.168.0.105:capsule2.bin && efidebug capsule update -v
0x100000
And then perform reset to them. I would expect that the same should work also
for empty capsules. I am not able to get in this to trial state but I expect
this is simply because I am not creating TrialStateCtr variable by hand.
Take a look at log below.
Thanks,
Michal
