skiboot-6.0.19

skiboot 6.0.19 was released on Tuesday March 19th, 2019. It replaces skiboot-6.0.18 as the current stable release in the 6.0.x series.

It is recommended that 6.0.19 be used instead of any previous 6.0.x version due to the bug fixes it contains.

Bug fixes included in this release are:

• p9dsu: Undo slot label name changes

  During some code updates the slot labels were updated to reflect the phb layout, however expectations were that the slot labels be aligned with the riser card slots and not the system planar slots.

  [stewart: The tale of how we got here is long and varied and not at all clear. The first ESS systems went out with a skiboot v5.9.8 with additional SuperMicro patches. It was probably a slot table, but who knows, we don’t have the code so can’t check. It’s possible it was all coming in through HDAT instead). The op-build tree (thus the exact patches) shipped on systems that work correct seems to not be around anywhere anymore (if it ever was). It was only in skiboot v6.0 that a slot table made it in, and, of course, only having remote machines in random configs, including possibly with riser cards from Briggs&Stratton rather than the ones destined for this system, doesn’t make for verifying this at all. It also doesn’t help that consistently there is never any review on slot tables, and we’ve had things be wrong in the past. Combine this with not upstream Hostboot patches.]

• p9dsu: Fix slot labels for p9dsu2u

  Update the slot labels for the p9dsu2u tables.
