1.. _skiboot-5.10.4: 2 3============== 4skiboot-5.10.4 5============== 6 7skiboot 5.10.4 was released on Wednesday April 4th, 2018. It replaces 8:ref:`skiboot-5.10.3` as the current stable release in the 5.10.x series. 9 10It is recommended that 5.10.3 be used instead of any previous 5.10.x version 11due to the bug fixes and debugging enhancements in it. 12 13Over :ref:`skiboot-5.10.3`, we have one bug fix: 14 15- xive: disable store EOI support 16 17 Hardware has limitations which would require to put a sync after each 18 store EOI to make sure the MMIO operations that change the ESB state 19 are ordered. This is a killer for performance and the PHBs do not 20 support the sync. So remove the store EOI for the moment, until 21 hardware is improved. 22 23 Also, while we are at changing the XIVE source flags, let's fix the 24 settings for the PHB4s which should follow these rules : 25 26 - SHIFT_BUG for DD10 27 - STORE_EOI for DD20 and if enabled 28 - TRIGGER_PAGE for DDx0 and if not STORE_EOI 29
