Bjorn,
Can we extend this aerdriver to support AER from a root complex integrated
endpoint? Root complex event collector has the same job as root port in this
case.
It looks that both port driver and aer driver check
PCI_EXP_TYPE_ROOT_PORT/PCI_EXP_TYPE_UPSTREAM/PCI_EXP_TYPE_DOWNSTREAM only.
portdrv_pci.c:127, aerdrv.c:86
Is it just a simple addition of PCI_EXP_TYPE_RC_EC to above two places?
Is there any difference to recover a root complex integrated endpoint?
(compared with devices connected to root port).
Thanks.
