All,
I am new to this mailing list. I got AER driver working for my platform with a pcie root complex driver. However one of my customer is using AHCI over PCI and I find that the driver currently doesn't provide error handler and ignore pci errors. Is this intentional? Could someone provide some input on this? I had to add code to enable error bits (PCI_COMMAND) and call pci_enable_pcie_error_reporting () to enable error reporting to the driver to test the AER driver. But curious why this is currently not supported in the driver. If there is any patch to address, please provide me a link.
Thanks
