Release v1.99.4

Release v1.99.4

I released a tag v1.99.4 as our next development milestone towards
v2.0.  There are 209 commits between v1.99.4 and v1.99.3, plus the
usual many more commits in sub-repositories we manage.

Big changes in this tag:
    * Upgrade from Yocto 2.2 to Yocto 2.1.
        - This was a major change in Yocto/Bitbake.  They upgraded
          all bitbake scripts from python2 to python3.
    * Power9 systems use OpenFSI and compiled application for processor
      control instead of shell scripts.
    * Elimination of "debug mode" in favor of systemd targets:
        - External FSI control for Cronus is done by systemd targets.
        - Automatic reboot of the host can be disabled independently
          by systemd targets.  This leaves the system in quiesce state
          when the host-watchdog fail or checkstop detection occurs.
    * LED management is refactored out of 'skeleton' and old
      /org/openbmc interfaces are removed.
    * Soft power-off should be supported.
        - This allows the host OS to gracefully shutdown on a power-off
          request.
    * Inventory:
        - All local EEPROM and host-IPMI based inventory is migrated to new
          /xyz/openbmc_project interfaces.
        - Fan presence should be reported to inventory.
    * P8/P9 eSEL IPMI commands create /xyz/openbmc_project error events.
    * Error events allow associations to inventory items for suggested
      hardware replacement actions.
        - Triggering fault LED actions as a side-effect should be coming
          in v1.99.5.
    * Support BMC reboot while Host is kept running.
        - The systemd target support for this was completed, but some
          systems may still have trouble successfully coming out of a
          reboot.

This should have read:

    * Upgrade to Yocto 2.2 from Yocto 2.1.

A few points and queries:

Building OpenBMC on "small" systems (e.g. systems with less than 8GiB
of RAM) may fail, as we hit a libstdc++ bug as a result of the upgrade:

As a note, pdbg has been "moved" to the debug tarball and is no-longer
available on the system out-of-the-box.

Patrick: Do you have a link to documentation of these targets? Ideally
these announcements would also provide these pointers.

Again, is there documentation?

Cheers,

This was posted to the mailing list recently.

Matt Spinler, can you put a commit into openbmc/docs to permanently
document?

https://github.com/openbmc/phosphor-dbus-interfaces is the starting
point for all dbus interfaces now. State-management is pretty well
documented: https://github.com/openbmc/phosphor-dbus-interfaces/tree/master/xyz/openbmc_project/State

Your specific question about soft power-off, this is the default now for
the host object.  If you want to simply pull power (hard power-off) you
operate on the chassis object.

As I reviewed some commits still in Gerrit today, I realized this might
not be as complete as I thought it was.  Look for this to be fully baked
in v1.99.5.
