Point the sysfs directory of bus->dev doesn't exist any more and its Pci_remove_bus_device(), it calls device_unregister(&bus->dev), but at this The sysfs directory of the device's subordinate bus (dev->subordinate) andĬonsequently, when pci_remove_bus() is called for dev->subordinate in Removed recursively along with all of its subdirectories. Pci_stop_dev() as it now causes the sysfs directory of the device to be Some investigation documented in kernel bug #65281 led me to theĬonclusion that the source of the problem is the device_del() in (Mika Westerberg sees them too in his tests). pci_stop_and_remove_bus_device+0x19/0x20 Hardware name: Acer Aspire S5-391/Venus, BIOS V1.02 WARNING: CPU: 3 PID: 76 at /scratch/rafael/work/linux-pm/fs/sysfs/group.c:214 sysfs_remove_group+0x59/0xe0() I'm seeing traces analogous to the one below in Thunderbolt testing: Version which he went at great lengths and pains to submit on aĪfter commit bcdde7e (sysfs: make _sysfs_remove_dir() recursive) x86: Booted up 16 nodes, 128 CPUsĬhange num_digits() to hpa's division-avoiding, cell-phone-typed

Interesting part is that I didn't find any traces of the relevant code inside android.c - so I think it is not related anyhow.Īlso, let us know where are you willing to continue this conversation. Observing dmesg log of android, these function are called when you attach usb host to the OTG port, but they are not when running ubuntu.
I was inspecting their code for a little and I think that sw_udc.c::sw_usb_device_enable function needs to be called and it is not.įrom usb_msg_center.c::insmod_device_driver

We just need to find out how to enable the UDC device. Anyway, I tried both ways and from my observation, the UDC device is not activated, so both cases are not working as a result of it.Īmery, I am not sure android.c needs to be rewritten, because from my observation it is mostly related to adb and custom mass storage implementation.

YuukiHogo, I know that UCD supports single gadget driver on top of it, but inside menuconfig you can preselect a driver (I tried putting serial or hid drivers instead of android) or compile it with no in-kernel driver and insmod one of the modules later (the injection procedure seems to be implemented). RobVanDerHoeven, USBC_OTG_SelectMode function is not called anywhere (and it is not system function as far as I know - so it is not important) g_serial gadget: interface 1 = acm0/e72a2f00 g_serial gadget: interface 0 = acm0/e72a2f00
