PCI-Express AER support in Driver.

[vipin240406]

I have developed a
PCI-Express Device driver for a end point device. I want to get
support of AER in my driver. I have checked device configuration space
AER is enabled there.

So please reply for following queries :

1. what steps I have to follow for this ?
2. Is this compulsory to define error handler ?
3. How can I test my driver that AER is working or not ?
4. I were try the same test case

A PCI Express device only
has one function, when kernel reads the ClassID from
the configuration space of the second function of the
device, the device might send an Unsupported Request
error message to the root port and set the bit in uncor-
rectable error status register.

for this device is changing the configuration space register
bits but driver is not sending any error messeges to Root Port performing any recovery why is it so ?

hello,

Were you able to find solution to test PCIe AER? If yes then please let me know how have you done that?

Thanks.
