As both hub devices share a FuVliUsbhubDeviceClass instance we cannot 'hijack'
the vfuncs depending on object type. This allows the downstream hub to proxy to
the upstream hub where a GPIOB reset can be performed.
We can have multiple FuVliPdDevice objects registered with the daemon, but they
will all share the FuVliPdDeviceClass instance. If one device requries a
silicon workaround, do not 'hijack' the vfunc for all devices of this type.
This means we do the right thing when updating both the one that requires the
workaround, and the 'normal' one.
The USB 2.0 controller is used as a 'backup' in case the USB 3.0 firmware fails
to start. Set USB 3 hubs as a greater priority so that the USB 2 ones do not
not get added if the USB 3 firmware is working.
This is nice in theory, until you need to look at the bootloader status of the
parent, or of a different device entirely. Handle this in plugins for the few
cases we care about and stop setting or clearing IS_BOOTLOADER manually just to
get the vfuncs to be run.
Note: I do not think we want to use cleanup() for attaching devices not in
bootloader states -- as cleanup is only run at the end of the composite update.
Doing this unconditionally means we accidentally 'bleed' one device mode into
another in a non-obvious way. For instance, a device might have two operating
modes with different GUIDs. If firmware is supplied for both modes in the same
cabinet archive then we might accidentally match the 'wrong' firmware when
the daemon has observed a mode switch and added the counterpart GUIDs.
We only really need the counterpart GUIDs when switching between Jabra, 8bitdo
and DFU devices where the DFU bootloader VID:PID is not manually tagged with
`CounterpartGuid` in a quirk file. In the general case lets keep it simple to
avoid difficult to find bugs.
The cleanup action for the FuVliUsbhubPdDevice is correct, but was not
conditionalized in the composite cleanup, which meant we would reboot twice
for a normal USB hub update.
Move the parent reboot into the right place, although this does mean we might
reboot twice in the rare event of scheduing a FuVliUsbhubPdDevice *and*
FuVliUsbhubDevice update in the same transaction -- but resetting the device
state between updates is arguably correct anyway...
Sometimes we only want to add the instance ID to get the quirk matches, and it
is confusing to see the "fake" IDs in the 'fwupdmgr get-devices' output.
This works around a silicon errata which makes the existing 0xB0 chip reset
non-functional.
ALso, as VL10x and VL103 are so different now, use different `->attach()` and
`->detach()` implementations for code sanity.
Based on a patch by Sherlock Chu <SherlockChu@via-labs.com>, many thanks.
I misunderstood the original specification, and it seems even USB-hub-less
devices have the same header location as their "write-through" counterparts.
The logic was wrong; we should have been using command 0xB0 for attach back to
FW mode for both VL10x and VL103. Using a generic reset on VL103 always reset
the device back into bootloader mode as the ROM signatures were being written
by command 0xC0.
As now attach and detach have different code paths, there's no point having a
`FuVliDevice->reset()` vfunc, and so we can make everything a little simpler at
the same time.
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.
