  Trigger a checkstop on unrecoverable MCE/HMI errors to inform BMC/OCC
  about the error.

Bug description:
  The current implementation of Machine Check handler and HMI handler in
  Linux, goes down kernel panic path for unrecoverable errors. On FSP
  based system FSP also gets notified about these errors which then
  forwards it to PRD (that runs on FSP) for error analysis and gard
  record creation.

  On OpenPower (BMC based system e.g. Habanero from TYAN) where PRD runs
  in Linux host, it never gets a chance to do error analysis at the time
  of Linux crash and no gard record is created for such errors. Since
  the faulty component never gets de-configured, the system is
  vulnerable to get hit by same HW error again.

  To fix this issue, a new OPAL call 'opal_cec_reboot2()' has been
  introduced to trigger a checkstop on BMC based system to inform
  BMC/OCC about this error, so that BMC can collect relevant data for
  error analysis and decide what component to de-configure before
  rebooting. Linux kernel should invoke this opal call for unrecoverable
  MCE and HMI instead before calling kernel panic so that OCC is
  informed about the error.

  The kernel changes has already been posted to upstream and are listed
  below:

[Kernel-packages] [Bug 1482343] Re: Trigger a checkstop on unrecoverable MCE/HMI errors to inform BMC/OCC about the error.

2015-10-26 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-
vivid' to 'verification-done-vivid'.

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!

Title:
  Trigger a checkstop on unrecoverable MCE/HMI errors to inform BMC/OCC
  about the error.

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Wily:
  Fix Released

Bug description:
  The current implementation of Machine Check handler and HMI handler in
  Linux, goes down kernel panic path for unrecoverable errors. On FSP
  based system FSP also gets notified about these errors which then
  forwards it to PRD (that runs on FSP) for error analysis and gard
  record creation.

  On OpenPower (BMC based system e.g. Habanero from TYAN) where PRD runs
  in Linux host, it never gets a chance to do error analysis at the time
  of Linux crash and no gard record is created for such errors. Since
  the faulty component never gets de-configured, the system is
  vulnerable to get hit by same HW error again.

  To fix this issue, a new OPAL call 'opal_cec_reboot2()' has been
  introduced to trigger a checkstop on BMC based system to inform
  BMC/OCC about this error, so that BMC can collect relevant data for
  error analysis and decide what component to de-configure before
  rebooting. Linux kernel should invoke this opal call for unrecoverable
  MCE and HMI instead before calling kernel panic so that OCC is
  informed about the error.

  The kernel changes has already been posted to upstream and are listed
  below:
