Do you mean changing "if ((host->native_aer || pcie_ports_native) && aer)" into "if (pcie_aer_is_native(dev) && aer)" ?
I thought changing into "if (pcie_aer_is_native(dev))" before.
One another doubt. Not every pci device support aer. When dev->aer_cap is NULL and root->aer_cap is not NULL in aer_root_reset(), pcie_aer_is_native() will return false and OS cannot operate root register. It's different from just using "(host->native_aer || pcie_ports_native)".
Or we can change "if ((host->native_aer || pcie_ports_native) && aer)" into "if (pcie_aer_is_native(root))". But in this way, argument NULL pointer check should be added in pcie_aer_is_native().
Looking into it again, I think it is better to leave it as it is. Please ignore my comment.
Thanks! Is there anything else to improve and what's next for
the patch v3 ?
