skiboot-5.10.4
|
|
==============
|
|
|
|
skiboot 5.10.4 was released on Wednesday April 4th, 2018. It replaces
|
|
:ref:`skiboot-5.10.3` as the current stable release in the 5.10.x series.
|
|
|
|
It is recommended that 5.10.3 be used instead of any previous 5.10.x version
|
|
due to the bug fixes and debugging enhancements in it.
|
|
|
|
Over :ref:`skiboot-5.10.3`, we have one bug fix:
|
|
|
|
- xive: disable store EOI support
|
|
|
|
Hardware has limitations which would require to put a sync after each
|
|
store EOI to make sure the MMIO operations that change the ESB state
|
|
are ordered. This is a killer for performance and the PHBs do not
|
|
support the sync. So remove the store EOI for the moment, until
|
|
hardware is improved.
|
|
|
|
Also, while we are at changing the XIVE source flags, let's fix the
|
|
settings for the PHB4s which should follow these rules :
|
|
|
|
- SHIFT_BUG for DD10
|
|
- STORE_EOI for DD20 and if enabled
|
|
- TRIGGER_PAGE for DDx0 and if not STORE_EOI
