skiboot-5.9.3
|

|
|
=============
|

|
|
|
||
|
|
skiboot 5.9.3 was released on Wednesday November 22nd, 2017. It replaces
|
||
|
|
:ref:`skiboot-5.9.2` as the current stable release in the 5.9.x series.
|
||
|
|
|
||
|
|
Over :ref:`skiboot-5.9.2`, we have one NPU2/NVLink2 fix that causes the
|
||
|
|
machine to crash hard in the event of hardware error rather than crash
|
||
|
|
mysteriously later on whenever the NVLink2 links are used.
|
||
|
|
|
||
|
|
That fix is:
|
||
|
|
|
||
|
|
- npu2: hw-procedures: Add check_credits procedure
|
||
|
|
|
||
|
|
As an immediate mitigator for a current hardware glitch, add a procedure
|
||
|
|
that can be used to validate NTL credit values. This will be called as a
|
||
|
|
safeguard to check that link training succeeded.
|
||
|
|
|
||
|
|
Assert that things are exactly as we expect, because if they aren't, the
|
||
|
|
system will experience a catastrophic failure shortly after the start of
|
||
|
|
link traffic.
