I tried asking the linux-pci mail list but got no response, so I thought I should really ask a more powerpc centric audience. I am working with a Freescale P2020 based embedded system that includes an IDT PCIe switch with x1 PCIe lanes to custom PCIe devices on a backplane. I was hoping to use the AER driver to get more info about any PCIe errors that may occur between the IDT switch and the PCIe devices. The embedded system uses a board support package currently based on Gentoo Linux with kernel 3.0.4. I guess the first question is does the 3.0.4 kernel support PCIe AER driver on powerpc? I found one related old post from 2010 but the behavior I observe is different than what is described in this post: http://thread.gmane.org/gmane.linux.kernel.pci/9685/focus=9709 My assumption is that if the AER driver is working properly, I should see some kernel log entries that include "... service driver aer loaded" which come from pcie_port_probe_service() in drivers/pci/pcie/portdrv_core.c. Is that a correct assumption? Here is a summary of what I see: In drivers/pci/pcie/aer/aerdrv.c: - aer_service_init() gets call at boot and appears to be successful returning 0 - aer_probe() never gets called In drivers/pci/pcie/portdrv_core.c: - pcie_port_service_register() gets called from aer_service_init() at boot, as expected it shows service name "aer" and returns 0 - pcie_port_probe_service() never gets called, I assume this would likely cause aer_probe() to get called - pcie_port_device_register() gets called for many of the PCIe devices in the system and completes successfully for many cases where service=0x02 (AER) is included I end up with many devices in "/sys/bus/pci_express/devices" with names that end in "2" indicating that they are successfully associated with the AER service. There is also a directory /sys/bus/pci_express/drivers which contains an "aer" entry. # ls /sys/bus/pci_express/devices 0000:01:00.0:pcie18 0000:02:11.0:pcie22 0000:02:14.0:pcie28 0000:05:00.0:pcie12 0000:06:05.0:pcie28 0000:06:0d.0:pcie22 0000:02:08.0:pcie22 0000:02:11.0:pcie28 0000:02:15.0:pcie22 0000:05:00.0:pcie18 0000:06:07.0:pcie22 0000:06:0d.0:pcie28 0000:02:08.0:pcie28 0000:02:12.0:pcie22 0000:02:15.0:pcie28 0000:06:01.0:pcie22 0000:06:07.0:pcie28 0000:06:0f.0:pcie22 0000:02:0c.0:pcie22 0000:02:12.0:pcie28 0000:02:16.0:pcie22 0000:06:01.0:pcie28 0000:06:09.0:pcie22 0000:06:0f.0:pcie28 0000:02:0c.0:pcie28 0000:02:13.0:pcie22 0000:02:16.0:pcie28 0000:06:03.0:pcie22 0000:06:09.0:pcie28 0000:07:00.0:pcie18 0000:02:10.0:pcie22 0000:02:13.0:pcie28 0000:02:17.0:pcie22 0000:06:03.0:pcie28 0000:06:0b.0:pcie22 0000:08:01.0:pcie22 0000:02:10.0:pcie28 0000:02:14.0:pcie22 0000:02:17.0:pcie28 0000:06:05.0:pcie22 0000:06:0b.0:pcie28 0000:08:02.0:pcie22 # ls /sys/bus/pci_express/drivers/aer bind uevent unbind Any idea why pcie_port_probe_service() is never called?
