Changes in v7:
- Dropped Rockchip Root port reset patch due to reported issues. But the series
  works on other platforms as tested by others.

Are you referring to

## On EP side:
# echo 0 > /sys/kernel/config/pci_ep/controllers/a40000000.pcie-ep/start && \
  sleep 0.1 && echo 1 > /sys/kernel/config/pci_ep/controllers/a40000000.pcie-ep/start

Then running pcitest only having 7 / 16 tests passed ?

If so, isn't that a problem also for qcom?

No, tests are passing on my setup after link up.

There is no chance that the patch:
"misc: pci_endpoint_test: Add AER error handlers"
improves things in this regard?

Or will it simply avoid the "AER: device recovery failed" print?

Yes, as mentioned in the commit message, it just avoids the AER recovery failure
message.

I also realized that Endpoint state is not saved in all the code paths. So the
pci_endpoint_test driver has to save/restore the state also. But it is still not
clear why that didn't help you.

Can you share the snapshot of the entire config space before and after reset
using 'lspci -xxxx -s "0000:01:00"'?
