Hi Claudiu,

So, I applied your patches on current -next and did the above.

During LinkUp the card (Renesas USB3 host controller) got correctly
re-initialized. Same for physical unplug/plug.

Thank you for testing this series!


I don't know nothing about PCI, but I wondered about one thing: after
removal (both physically and via I2C), the card was still present in
/sys/bus/pci/devices. Is that expected?

I currently can't reproduce this on my side. Do you remember if you executed the below command before your test:

echo performance > /sys/module/pcie_aspm/parameters/policy

?

Thank you,
Claudiu
