This change will allow it to use pkcon over remote-shells (ssh) or
to use it witout a running GUI desktop environment in the background.
Should fix https://github.com/fwupd/fwupd/issues/2429
If we wait for the child of a composite device to reappear and *then* go on to
update the replugged parent in the same transaction then we still use the old
GUsbDevice as the add event is still pending when we quit the replug loop.
Just schedule an idle action to quit the loop to allow the child *and* parent
to be added on replug.
Fixes https://github.com/fwupd/fwupd/issues/2376
Use one of the errors mapping to FWUPD_UPDATE_STATE_FAILED_TRANSIENT to avoid
uploading a failure report for something the user has to fix, i.e. update the
distro shim package.
Conceptually we were trying to stuff subtly different actions into one vfunc:
* Read firmware from the device to update the verification checksums
* Read a firmware blob from the device for debugging
For the first action we might want to mask out the sections of the flash with
serial numbers (so the verification hashes match the ones published on the LVFS)
and for the second we want just a raw ROM file from the hardware with no
pre-processing that we can compare against an external SPI dumper.
Split out ->dump_firmware to get the raw blob, and allow plugins to also
implement ->read_firmware() if they have to mask out specific offsets or remove
specific images from the FuFirmware container.
In the common case when masking is not required, fall back to using a 'binary'
FuFirmware automatically to make most plugins simpler.
At the moment there are commands to convert one file format to another, but not
to 'merge' or alter them. Some firmware files are containers which can store
multiple images, each with optional id, idx and addresses.
This would allow us to, for instance, create a DfuSe file with two different
raw files that are flashed to different addresses on the SPI flash. It would
also allow us to create very small complicated container formats for fuzzing.
This can be used by writing a `firmware.builder.xml` file like:
<?xml version="1.0" encoding="UTF-8"?>
<firmware gtype="FuBcm57xxFirmware">
<version>1.2.3</version>
<image>
<version>4.5.6</version>
<id>header</id>
<idx>456</idx>
<addr>0x456</addr>
<filename>header.bin</filename>
</image>
<image>
<version>7.8.9</version>
<id>payload</id>
<idx>789</idx>
<addr>0x789</addr>
<data>aGVsbG8=</data>
</image>
</firmware>
...and then using something like:
# fwupdtool firmware-convert firmware.builder.xml firmware.dfu builder dfu
For containers with multiple images it is sometimes very helpful to know what
file they've been loaded from. This would also allow us to 'explode' the
firmware container into seporate image files on disk.
