I'm working on testing AER with module "aer_inject", but with my hardware, the module stops at
pos_cap_err = pci_find_ext_capability(dev, PCI_EXT_CAP_ID_ERR);
or
rp_pos_cap_err = pci_find_ext_capability(rpdev, PCI_EXT_CAP_ID_ERR);
On my hardware, "lspci -t && lspci -vvv" prints info as below:
localhost ljf # lspci -t && lspci -vvv

Only 02:00.0 and 03:00.0 have the Advanced Error Reporting capability, the corresponding root ports (00:1c.0 and 00:1c.1) don't have the Advanced Error Reporting capability, so the aer_inject can not going on.
I'm looking for hardware which support the aer injections, please help me.

CentOS 6.2: need help getting aer_inject to work
Thanks for starting your own thread. Not sure if [url=https://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=35693&forum=45]this thread[/url] adds anything, but here it is for completeness.
This seems to be a rather esoteric topic, and you have seemingly provided both more and less than we need to know. I do find
[code]$ locate aer_inject
/lib/modules/2.6.32-131.21.1.el6.i686/kernel/drivers/pci/pcie/aer/aer_inject.ko

[/code]but am clueless as to what it is supposed to do. A google on [url=http://www.google.com/search?q=aer_inject&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:unofficial&client=firefox-a]aer_inject[/url] is not terribly informative, but does find references to a userland tool aer-inject:[code]

You need to provide a bit more background about your issue, or just wait in the hope that someone knowledgeable about this happens by. I'm not that someone. :-)
