Thomas Tai 2af8641b2a PCI/AER: Add TLP header information to tracepoint ... When a PCIe AER error occurs, the TLP header information is printed in the kernel message but it is missing from the tracepoint. A userspace program can use this information in the tracepoint to better analyze problems. To enable the tracepoint: echo 1 > /sys/kernel/debug/tracing/events/ras/aer_event/enable Example tracepoint output: $ cat /sys/kernel/debug/tracing/trace aer_event: 0000:01:00.0 PCIe Bus Error: severity=Uncorrected, non-fatal, Completer Abort TLP Header={0x0,0x1,0x2,0x3} Signed-off-by: Thomas Tai <thomas.tai@oracle.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Steven Rostedt (VMware) <rostedt@goodmis.org>		2018-05-10 08:34:52 -05:00
