Subject: [PATCH v7 1/3] aerdrv: Trace Event for AER
Date: Tue, 04 Dec 2012 14:03:05 -0700 [thread overview]
Message-ID: <20121204210305.4515.91100.stgit@grignak.americas.hpqcorp.net> (raw)
This header file will define a new trace event that will be triggered when
a AER event occurs. The following data will be provided to the trace
event.
char * dev_name - The name of the slot where the device resides
([domain:]bus:device.function).
u32 status - Either the correctable or uncorrectable register
indicating what error or errors have been see.
u8 severity - error severity 0:NONFATAL 1:FATAL 2:CORRECTED
The trace event will also provide a trace string that may look like:
"0000:05:00.0 PCIe Bus Error:severity=Uncorrected (Non-Fatal), Poisoned
TLP"
v1-v2 Move header from include/ras/aer_event.h to
include/trace/events/ras.h
v3-v4 Cleaned up comments and commit header
v4-v5 More cleanup remove () from if statement in print.
Renamed string define to be more specific.
v5-v6 change TRACE_SYSTEM define to be ras and not aer.
