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?


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?


Kind regards,
