This flag is used internally by plugins to indicate that they will
skip the phase of firmware installation that power cycles a device.
It is intended to be set by quirks or other environment settings.
If we say that the version format should be the same for the `version_lowest`
and the `version_bootloader` then it does not always make sense to set it at
the same time.
Moving the `version_format` to a standalone first-class property also means it
can be typically be set in the custom device `_init()` function, which means we
don't need to worry about *changing* ther version format as set by the USB and
UDev superclass helpers.
In 1de7cc we checked the version format when checking for update, but there are
many other places that are doing verfmt-insensitive comparisons. For instance,
the predicates in <requires> all fail if the device version format is plain.
his breaks updating some NVMe drives where the `ne` requirements are not
semantic versions.
To avoid trying to catch all the bugs in different places, and in case we have
a future verfmt that should be treated another way, refactor this out in to a
common function and deprecate the old function.
Some plugins have devices with more than one protocol. Logically the protocol
belongs to the device, not the plugin, and in the future we could use this to
further check firmware that's about to be deployed.
This is also not exported into libfwupd (yet?) as it's remains a debug-feature
only -- protocols are not actually required for devices to be added.
In many plugins we've wanted to use ->prepare_firmware() to parse the firmware
ahead of ->detach() and ->write_firmware() but this has the limitation that it
can only return a single blob of data.
For many devices, multiple binary blobs are required from one parsed image,
for instance providing signatures, config and data blobs that have to be pushed
to the device in different way.
This also means we parse the firmware *before* we ask the user to detach.
Break the internal FuDevice API to support these firmware types as they become
more popular.
This also allows us to move the Intel HEX and SREC parsing out of the dfu plugin
as they are used by a few plugins now, and resolving symbols between plugins
isn't exactly awesome.
This leads to madness, as some formats are supersets of the detected types,
e.g. 'intel-me' is detected as 'quad' and 'bcd' is detected as 'pair'.
Where the version format is defined in a specification or hardcoded in the
source use a hardcoded enum value, otherwise use a quirk override.
Additionally, warn if the version does not match the defined version format
EC23 is the last version that will be supported on board 4 SKUs with
base PD firmware versions 18+.
* If on EC23 already, don't mark the device as updatable anymore.
* Flashing EC24 or later when currently on EC 22 or less will potentially
cause bricked docks that can't enumerate, so prevent this scenario
during update path.
This behavior will prevent the dock from performing most resets until
it has been unplugged from a host system.
This significantly speeds up the perceived update duaration and prevents
data loss during update.
It's not confirmed whether EC23 or later EC will enable it.
* So only enable by a custom flag until this is confirmed.
* Custom flag will be dropped when included into stable EC release.
This functionality also relies upon the CAB file providing a message warning
user that the dock might not be usable after unplugging for up to 1 minute.
Some SKUs of board 4 and later have silicon that will not work with anything
but EC19 or later. So once flashed up to EC19 prohibit downgrades below that
to keep from bricking devices.
This is probably fall out from a previous code re-shuffling.
The EC version is already set elsewhere, and in many cases `self->ec_version`
is `NULL` at this time.
Board 4 was manufactured with package version 89.16.01.00 and this
will prevent properly upgrading between releases. Reset this version
to 00.00.00.00 if detected on this board.
Otherwise this would cause fwupd to sit in an endless loop when providing a bad
image.
This additional enum is only available in EC16, but since it doesn't break existing
API on older EC images, don't bump minimum requirement to EC16 yet.
The libxmlb library is much faster to query, and does not require the daemon
to parse the XML metadata at startup. It's a zero-copy mmap design that is more
modern and less clunky.
RSS has reduced from 3Mb (peak 3.61Mb) to 1Mb (peak 1.07Mb) and the startup
time has gone from 280ms to 250ms.
These are certainly bugs with one of the components, but if the situation
happens in the field the plugin needs to finish initialization to allow
upgrading to a fixed component.
We'll just fall back to the name in the quirk (Dell dock) in this case.
This plugin requires infrastructure introduced in fwupd 1.1.3
and can not be backported to earlier versions of fwupd.
It works together with the Synaptics and Thunderbolt plugins to
coordinate the proper flashing procedure for devices in this dock.
