Trying to explain why ICL thunderbolt isn't updatable doesn't help
people. It just causes fwupdmgr and fwupdtool to show the device
front and center with a confusing message.
Instead don't populate the message and by the default device filter
it will be hidden.
See #2212 for background.
This allows delaying the activation of Thunderbolt firmware until
shutdown/reboot or when the dock is unplugged.
This functionality requires features in the kernel:
https://lore.kernel.org/linux-usb/20200622143035.25327-1-mario.limonciello@dell.com/T/#t
Matrix of cases to support:
* Distro Old Linux kernel (doesn't support authenticate on disconnect)
- WD19TB: Should have `skips-restart` flag set
No flush or activate features called in `thunderbolt` plugin.
`dell_dock` plugin will activate at end of composite update
- All other devices: Shouldn't have flags set
Should authenticate in Thunderbolt plugin.
`1 > nvm_authenticate`
* Distro New Linux kernel (supports authenticate on disconnect)
- WD19TB: Should have `usable-during-update` flag set but not `skips-restart`
Should flush image to SPI in `thunderbolt` plugin
`2 > nvm_authenticate_on_disconnect`
Should configure TBT device for authenticate on disconnect
`1 > nvm_authenticate_on_disconnect`
`dell_dock` plugin will configure dock for authenticate on disconnect
- All other devices: Shouldn't have flags set
Should authenticate in `thunderbolt` plugin.
`1 > nvm_authenticate`
* ChromeOS (supports authenticate on disconnect)
- `thunerbolt.conf` will have `DelayedActivation=true`.
- WD19TB: Should have `usable-during-update` flag set but not `skips-restart`
Should flush image to SPI in `thunderbolt` plugin
`2 > nvm_authenticate_on_disconnect`
Should configure device for authenticate on disconnect
`1 > nvm_authenticate_on_disconnect`
`dell_dock` plugin will configure dock for authenticate on disconnect
- All other devices: Should have both `usable-during-update` and `skips-restart` set
Should flush image to SPI in `thunderbolt` plugin
`2 > nvm_authenticate`
Will activate upon logout/shutdown/reboot
`1 > nvm_authenticate`
This flag is used internally by plugins to indicate that they will
skip the phase of firmware installation that power cycles a device.
It is intended to be set by quirks or other environment settings.
Thunderbolt images brought in from the SPI don't have a FARB header.
Thunderbolt update images do.
So these two types of images need to be handled separately from the
firmware parser.
The kernel interface for force power doesn't support tracking the state
of the device, and so this had to be tracked by fwupd.
Unfortunately due to system and thunderbolt controller firmware behavior
on some systems the thunderbolt controller /still/ didn't return even
when force power state was accurately tracked.
The device model for the uevent related to the device removal being ignored
doesn't really fit into the current fwupd architecture anymore either.
Lastly this is a very legacy feature at this point. Thunderbolt3 controllers
distributed in the last 3 years all operate in 'native' mode meaning that
they will always be powered and use runtime power management.
USB4 controllers won't have a concept of being force powered.
USB4 reimers will have this concept, but the state will be tracked by the
kernel and obfuscated from userspace.
So with all that said, tear out all of the force power related code.
Remove it's references to it's own GUdevclient and instead use
FuUdevDevice.
Some intentional casualties of the move:
* Plugin metadata around native and safe mode dropped.
- These haven't been useful in debugging anything and aren't relevant
on new hardware
* Extra GUID for 2 host controllers in same system dropped
- Although this was normally static information BIOS operations like
turning off PCI-E SD card reader or LAN controller changed things.
* The NVM version is parsed directly instead of through gudev to prevent
cached data breaking change events.
Remaining TODO:
* Force power w/ thunderbolt-power doesn't work
