skiboot-5.4.11 was released on Wednesday Dec 4th, 2019. It replaces skiboot-5.4.10 as the current stable release in the 5.4.x series.

Over skiboot-5.4.10, we have below bug fix to support inband ipmi interface:

  • FSP/IPMI: Handle FSP reset reload FSP IPMI driver serializes ipmi messages. It sends message to FSP and waits for response before sending new message. It works fine as long as we get response from FSP on time.

    If we have inflight ipmi message during FSP R/R, we will not get resonse from FSP. So if we initiate inband FSP R/R then all subsequent inband ipmi message gets blocked.

    • ipmitool mc reset cold

    • <FSP R/R complete>

    • ipmitool <any command> <– gets blocked

    This patch clears inflight ipmi messages after FSP R/R complete.
