More than one person has asked about 'why call fu_plugin_update() for a
reinstall or downgrade' and I didn't have a very good answer.
The plugin API is not officially stable, and we should fix things to be
less confusing. Use the same verbs as the FuDevice vfuncs instead.
The benefit of using the proxy device is that we can 'use' the proxy
device for device access, but 'report' the progress on the passed
FuDevice instance.
This means the front-end reports the device status correctly when
updating composite devices that us proxies.
The comment always said we should move it to the daemon if another
plugin started doing this, and that is now.
There are now multiple plugins using drm_dp_aux_dev interface which
may potentially be combined with an amdgpu. Prevent exercising this
interface with any plugin using DP aux unless a new enough kernel is
installed.
Until gi-docgen is declared stable support either of them.
This effectively means that hand builds and CI builds will use
gi-docgen, but distro builds use gtk-doc-tools.
Unloading the GModule means that any GTypes registered by that plugin cannot be
queried.
Other plugins could unintentionally call methods like G_OBJECT_TYPE_NAME()
which makes the daemon explode. There's no need to actually close the module,
and so we're just making life diffult for ourselves for no good reason.

There is a lot of code in fwupd that just assigns a shared object type to
a FuPlugin, and then for each device on that plugin assigns that same shared
object to each FuDevice.
Rather than proxy several kinds of information stores over two different levels
of abstraction create a 'context' which contains the shared *system* state
between the daemon, the plugins and the daemon.
This will allow us to hold other per-machine state in the future, for instance
the system battery level or AC state.
We already have two things managing the UPDATABLE_HIDDEN->UPDATABLE transition,
and we're about to add a third.
Add a 'stackable' inhibit-style API so we do not accidentally mark a device as
updatable when it should remain hidden.
Keeping *internal* API and ABI compatibility makes working with an already
complex codebase more mentally demanding than it needs to be.
Remember: plugins should be in-tree and upstream! If your out of tree plugin
stops working then it should be upstream.
The public-facing libfwupd will remain API and ABI stable for obvious reasons.
Rather than trying to guess typos, force each plugin to register the quirk
keys it supports, so we can show a sensible warning if required at startup on
the console.
The best way of not getting something wrong is to not require it in the first
place...
All plugins now use DeviceInstanceId-style quirk matches and we can just drop
the prefix in all files. We were treating HwId=, Guid= and DeviceInstanceId= in
exactly the same way -- they're just converted to GUIDs when building the silo!
If the user explicitly specifies the device-id then we do not do the front-end
filtering. If the device detaches without being able to attach then the hardware
could be left in the bootloader state.
See https://github.com/fwupd/fwupd/issues/2926#issuecomment-784234180
There are now two 'backends' of device plug/unplug events, and there is about
to become three. Rather than just adding two more vfuncs for every backend type
define common ones that all providers can use.
Also fix up the existing in-tree plugins to use the new vfunc names and filter
on the correct GType.
The end year is legally and functionally redundant, and more importantly causes
cherry-pick conflicts when trying to maintain old branches. Use git for history.
That giant uint64_t isn't looking so big now, and we'll want to add even more
to it in the future. Split out some private flags that are never useful to the
client, although the #defines will have to remain until we break API again.
The Thunderbolt plugin wasn't actually working properly for
`DelayedActivation` because Thunderbolt devices weren't actually registered.
This only affected ChromeOS.

For instance, we can tell the user that UEFI UpdateCapsule is disabled in the
system firmware, or that efivarfs is not mounted. This is much better than
creating "dummy" devices which are really just hacks around the problem because
no better API existed. THe dummy devices cause as many problems as they solve.
Plugins have to set FWUPD_PLUGIN_FLAG_USER_WARNING if a warning should be shown
to the user, and only one warning will be shown of each failure type.
It is expected that GUI clients like gnome-software and gnome-firmware would use
this API to notify the user the localized message for why firmware updates are
not being shown.
Fixes https://github.com/fwupd/fwupd/issues/2456
This would also help, for example, to go back to the nonfree firmware when the
alternate firmware did not work as well as hoped. It would also allow flashing
the firmware using an SPI programmer if everything went very wrong indeed.
