Now devices can have multiple GUIDs and do not share platform IDs there is
really no point waiting to add the device.
This allows us to remove a whole lot of code for this now-unused functionality.
This started popping up in Arch CI:
../fwupd/plugins/uefi/fu-uefi-vars.c: In function ‘fu_uefi_vars_get_data’:
../fwupd/plugins/uefi/fu-uefi-vars.c:233:9: error: pointer targets in assignment from ‘gchar *’ {aka ‘char *’} to ‘guint8 *’ {aka ‘unsigned char *’} differ in signedness [-Werror=pointer-sign]
*data = g_steal_pointer (&data_tmp);
^
Until now, the unifying plugin was a 'special snowflake' and did things in very
different ways to the other plugins. Refactor each object to derive from either
FuUsbDevice or FuUdevDevice, and then remove LuDevice and the LuContext layers.
It wasn't hugely clear what the platform ID was actually meant to represent. In
some cases it was being used like a physical ID, in others it was a logical ID,
and in others it was both. In some cases it was even used as a sysfs path.
Clear up all the confusion by splitting the platform ID into two parts, an
optional *physical* ID to represent the electrical connection, and an optional
*logical* ID to disambiguate composite devices with the same physical ID.
Also create an explicit sysfs_path getter for FuUdevDevice to make this clear.
This allows WAIT_FOR_REPLUG to always work, rather than depending on the order
that the GUIDs were added, and that the kernel would always return the same
sysfs path (which it doesn't have to do, especially for hidraw devices).
As an example use case earlier development versions of a Thunderbolt module
may contain DROM corresponding to one model ID and transition to another
model ID. Even if lying about the GUIDs supported by the device via a
quirk the Thunderbolt validation will fail because the device isn't
intended for that system.
This should only be used during development.
The daemon creates a baseclass of either FuUsbDevice or FuUdevDevice when the
devices are added or coldplugged to match the quirk database and to find out
what plugin to run.
This is proxied to plugins, but they are given the GUsbDevice or GUdevDevice and
the FuDevice is just thrown away. Most plugins either use a FuUsbDevice or
superclassed version like FuNvmeDevice and so we re-create the FuDevice, re-probe
the hardware, re-query the quirk database and then return this to the daemon.
In some cases, plugins actually probe the hardware three times (!) by creating
a FuUsbDevice to get the quirks, so that the plugin knows what kind of
superclass to create, which then itself probes the hardware again.
Passing the temporary FuDevice to the plugins means that the simplest ones can
just fu_plugin_device_add() the passed in object, or create a superclass and
incorporate the actual GUsbDevice and all the GUIDs.
This breaks internal plugin API but speeds up startup substantially and deletes
a lot of code.
If another plugin causes a Synaptics MST device to be removed, it
also needs to be removed from the cache to prevent problems when
the device is re-probed.
1) Switch to daemon provided vfuncs for USB
2) Set quirks so that the plugin only runs when Realtek NIC shows up
3) Rely on the daemon to process all removals by parent tree
The setup() is the counterpart to probe(), the difference being the former needs
the device open and the latter does not.
This allows objects that derive from FuDevice, and use FuDeviceLocker to use
open() and close() without worrying about the performance implications of
probing the hardware, i.e. open() now simply opens a file or device.
These are GUIDs that are related to the main device, but should not be used for
quirk matching. For instance, we might want to list the GUIDs for a bootloader
mode, but we don't want to import all the quirks for the bootloader when in the
runtime mode.
This flag is intended for devices that the restart procedure will
be performed as part of a transactional update by an external
controller.
None of the currently supported devices need this flag.
This allows us to match non-DeviceID GUIDs, and also GUIDs we don't know how to
generate.
To make this fully useful, search for device quirks when GUIDs are added.
This was compiling and passing CI as the un-implemented legacy functionality
was still exported in the header.
Remove the prototypes for the missing symbols and fix up the plugin.
