Hi,
I am not sure if this is the correct mailing list to ask about Driver Component Framework, so if I am mistaken, I would appreciate it if anyone can correct me to the right direction.
I have a quick question on using driver component framework and a strange crash I am seeing when I use component framework.
There is then component framework currently being used for typec connector, as below https://elixir.bootlin.com/linux/latest/source/drivers/usb/typec/port-mapper... We add component for usb port to link it with typec connector, as below https://elixir.bootlin.com/linux/latest/source/drivers/usb/core/port.c#L622 https://elixir.bootlin.com/linux/latest/source/drivers/usb/core/port.c#L568
We are trying to do something similar for usb4 port, add component to link to typec connector. I have attached a patch to this email for reference. However, this change causes a crash in kernel for some devices. The crash is too early in the kernel that it is not giving any logs at all. This crash is somehow fixed when we change usb4 config from =y (built-in) to =m (loadable module). So, I am curious if there are some aspects in the component framework that depends on whether the device with a component added is a built-in or loadable module.
If anyone has seen a similar issue or have an idea on what is happening, can you share your thoughts on what might be the issue and how the crash can be avoided? Thank you very much!
