skiboot-5.1.10 was released on Friday November 13th, 2015.

skiboot-5.1.10 is the 11th stable release of 5.1, it follows skiboot-5.1.9 (which was released October 30th, 2015).

Skiboot 5.1.10 contains all fixes from skiboot-5.1.9 and is a minor bug fix release.

Over skiboot-5.1.9, we have the following change:

IBM FSP machines

  • FSP: Handle Delayed Power Off initiated CEC shutdown with FSP in Reset/Reload

    In a scenario where the DPO has been initiated, but the FSP then went into reset before the CEC power down came in, OPAL may not give up the link since it may never see the PSI interrupt. So, if we are in dpo_pending and an FSP reset is detected via the DISR, give up the PSI link voluntarily.


  • sensor: add a compatible property OPAL needs an extra compatible property “ibm,opal-sensor” to make module autoload work smoothly in Linux for ibmpowernv driver.

  • console: Completely flush output buffer before power down and reboot Completely flush the output buffer of the console driver before power down and reboot. Implements the flushing function for uart consoles, which includes the astbmc and rhesus platforms.

    This fixes an issue where some console output is sometimes lost before power down or reboot in uart consoles. If this issue is also prevalent in other console types then it can be fixed later by adding a .flush to that driver’s con_ops.
