Hi,
I have a Lenovo Thinkpad t420s on which I've installed coreboot. However, the USB 3.0 port is not active and the controller is not listed under lspci.
Under the original Lenovo bios, the xhci device was at pci address 0d:00.0 behind bridge 00:1c.4.
It looks like the t420s devicetree.cb is set up for the xhci controller to be behind 00:1c.6. I changed that to 00:1c.4 and that got the xhci pci device to show up as 03:00.0. Strangely, booting into linux, it shows 001c.3 as the bridge to 03:00.0. Additionally, plugged in USB devices were not detected.
Here's where it gets weird. I had a mouse plugged in, and I was looking in sysfs. cat /sys/devices/pci0000:00/0000:00:1c.3/0000:03:00.0/enable 0 So the xhci pci device is disabled. I ran `lspci -vvnn` a few times in quick sucession - I was looking to see if it showed disabled - and the mouse lit up!
Plugging in a USB Flash drive, it was again not detected. The lspci trigger worked. Later, promptly switching USB devices resulted in the new USB device still being detected.
Is "PCH: PCIe map 1c.4 -> 1c.3" the remapping from the device tree 1c.4 to the 1c.3 that I see?
Below I've included the cbmem -c output and a snippet from an old lenovo BIOS dmesg w/ the pci address.
Does anyone have an idea of what is going on, or what I should investigate next? A total guess, but could poking the PCI device with lspci turn it on so that it may detect an attached device and then stay active? Maybe something with power management? Again, I'm just guessing. Any suggestions are appreciated.
Thanks, Jason

Hi Jason,

Hi,
I have a Lenovo Thinkpad t420s on which I've installed coreboot. However, the USB 3.0 port is not active and the controller is not listed under lspci.
Under the original Lenovo bios, the xhci device was at pci address 0d:00.0 behind bridge 00:1c.4.
It looks like the t420s devicetree.cb is set up for the xhci controller to be behind 00:1c.6. I changed that to 00:1c.4 and that got the xhci pci device to show up as 03:00.0. Strangely, booting into linux, it shows 001c.3 as the bridge to 03:00.0. Additionally, plugged in USB devices were not detected.
Note that the mainboard has pcie_port_coalesce set in the devicetree, so it can be wrong to just see the BDF address to know which port the XHCI device is connected to.
However, lspci also shows the port, it'll show `PCI Express Root Port X` where X is actually the port number (PCI function number + 1). The function number in the device tree is based on this port number.
Here's where it gets weird. I had a mouse plugged in, and I was looking in sysfs. cat /sys/devices/pci0000:00/0000:00:1c.3/0000:03:00.0/enable 0 So the xhci pci device is disabled. I ran `lspci -vvnn` a few times in quick sucession - I was looking to see if it showed disabled - and the mouse lit up!
Plugging in a USB Flash drive, it was again not detected. The lspci trigger worked. Later, promptly switching USB devices resulted in the new USB device still being detected.
Is "PCH: PCIe map 1c.4 -> 1c.3" the remapping from the device tree 1c.4 to the 1c.3 that I see?
Below I've included the cbmem -c output and a snippet from an old lenovo BIOS dmesg w/ the pci address.
Does anyone have an idea of what is going on, or what I should investigate next? A total guess, but could poking the PCI device with lspci turn it on so that it may detect an attached device and then stay active? Maybe something with power management? Again, I'm just guessing. Any suggestions are appreciated.
Thanks, Jason

lspci says PCI Express Root Port 5 which matched my devicetree modification.

Playing around a little more, I discovered the USB 3.0 port works normally when the laptop is plugged in. When on battery, the USB port doesn't detect device insertion in Linux. Booting with an inserted flash drive, Seabios detects and offers the device as a boot option.
Comparing lspci for battery vs. plugged in,

Disabling d3cold_allow on the xhci controller also seems to help device insertion when on battery. echo 0 > /sys/devices/pci0000:00/0000:00:1c.3/0000:03:00.0/d3cold_allowed It doesn't change the lspci output, but device insertion is again detected.
My understanding is d3cold requires some out of band signalling to awaken a device.
Looking at page 100 of these schematics: https://drive.google.com/file/d/0B6IqcVTk0jpYZ0ZvWVd3T1lFVHc/view
"If Wakeup function from D3 cold is required, VCC3_AUX should be applied from system." (Label next to it is VCC3_AUX_USB)
Also from page 100, it looks like VCC3_AUX_USB_ON controls VCC3_AUX_USB.
page 68 VCC3_AUX_USB_ON is pin 13, PGPIO3, of Thinker-1? The chip is labeled BU77700KVT-GP, which google doesn't really have an answer for.
Anyone have any ideas what this chip may be? Any other ideas or suggestions on what to investigate?
Regards, Jason
