This patch series aims at fixing some of the AER error handling issues
we have.
Currently we have the following issues:
1. Confusing message in aer_print_error()
2. aer_err_info not being initialized completely in DPC path before
we print the AER logs
3. A bug [1] in clearing of AER registers in the native AER path
[1] https://lore.kernel.org/linux-pci/20151229155822.GA17321@localhost/
The patch series fixes the above things.
PATCH 1:
- Fixes the first issue
- This patch is independent of other patches and can be applied
seperately
PATCH 2 - 3:
- Fixes the second issue
- Patch 3 is depended on Patch 2 in the series
PATCH 4
- Fixes the bug in clearing of AER registers which leades to
AER message spew [1]
PATCH 5:
- Adds extra information (devctl register) in AER error logs.
- Patch 5 depends on Patch 4 of the series
Thanks,
Naveen Naidu
