Title:
  PSL traces reset after PERST for debug AFU image

Status in The Ubuntu-power-systems project:
  Fix Released
Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Released

  ---Problem Description---
  Presently the Trace Data on the PSL is lost when it encounters a PERST 
signal. This is usually a major inconvenience during EEH debugging as PSL 
traces are needed to investigate the EEH cause. To fix this we enable the NORST 
bit by default for debug afu images to prevent reset of AFU trace-data on a PCI 
link drop. For production AFU images this bit is always ignored and PSL gets 
reconfigured anyways thereby resetting the trace data. So setting this bit for 
non-debug images doesn't have any impact.

  Fix for this issue was merged to mainline kernel via commit:

  03ebb419b896 cxl: Enable NORST bit in PSL_DEBUG register for PSL9
   
  ---Additional Hardware Info---
  Flash GT+ adapter with 180323P1 Image 

   
  Machine Type = Boston-LC 
   
  ---Steps to Reproduce---
   1. Enable traces on the card with psl_trace_dump tool.
  2. Inject an EEH.
  3. Try to dump the traces from PSL via psl_trace_dump.
   
  ---uname output---
  4.15.0-12-generic
   
  ---Debugger---
  A debugger is not configured
   
  System Dump Info:
The system is not configured to capture a system dump.

[Kernel-packages] [Bug 1762462] Re: PSL traces reset after PERST for debug AFU image

2019-02-14 Thread Brad Figg
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  ---Problem Description---
  Presently the Trace Data on the PSL is lost when it encounters a PERST 
signal. This is usually a major inconvenience during EEH debugging as PSL 
traces are needed to investigate the EEH cause. To fix this we enable the NORST 
bit by default for debug afu images to prevent reset of AFU trace-data on a PCI 
link drop. For production AFU images this bit is always ignored and PSL gets 
reconfigured anyways thereby resetting the trace data. So setting this bit for 
non-debug images doesn't have any impact.

  Fix for this issue was merged to mainline kernel via commit:

  03ebb419b896 cxl: Enable NORST bit in PSL_DEBUG register for PSL9
   
  ---Additional Hardware Info---
  Flash GT+ adapter with 180323P1 Image 

   
  Machine Type = Boston-LC 
   
  ---Steps to Reproduce---
   1. Enable traces on the card with psl_trace_dump tool.
  2. Inject an EEH.
  3. Try to dump the traces from PSL via psl_trace_dump.
