skiboot-5.1.13 was released on Wed January 27th, 2016.

skiboot-5.1.13 is the 14th stable release of 5.1, it follows skiboot-5.1.12 (which was released December 4th, 2015). This release contains bug fixes.


  • core/device.c: Sort nodes with name@unit names by unit

    • This gives predictable device tree ordering to the payload (usually petitboot)

    • This means that utilities such as “lspci” will always return the same ordering.

  • Add OPAL_CONSOLE_FLUSH to the OPAL API uart consoles only flush output when polled. The Linux kernel calls these pollers frequently, except when in a panic state. As such, panic messages are not fully printed unless the system is configured to reboot after panic.

    This patch adds a new call to the OPAL API to flush the buffer. If the system has a uart console (i.e. BMC machines), it will incrementally flush the buffer, returning if there is more to be flushed or not. If the system has a different console, the function will have no effect. This will allow the Linux kernel to ensure that panic message have been fully printed out.


  • hmi: Identify the phb upon CAPI malfunction alert Previously, any error on a CAPI adapter would assume PHB0. This could cause issues on Firestone machines.

gard utility

  • Fix displaying ‘cleared’ gard records When a garded component is replaced hostboot detects this and updates the gard partition.

    Previously, there was ambiguity on if the gard record ID or the whole gard record needed to be erased. This fix makes gard and hostboot agree.

firestone platform

  • fix spacing in slot name The other SlotN names have no space.
