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.
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.
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.
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
Quite a few plugins use HID commands to communicate with the hardware. At the
mement we have ~6 implementations of SET_REPORT and are soon to add one more.
Move this into common code.
