[PATCH 05/12] pcie, aer: fix report of multiple errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The flag AER_MULTI_ERROR_VALID_FLAG in info->flag does mean that the
root port receives multiple error messages.  Error messages can be
posted from different devices, so it does not mean that each reported
device has multiple errors.

If there are multiple error devices and the root port has valid error
source ID, it would be nice to report which device is the error source
reported first.

v2: Revice reported first message
