It is the new stable +release of skiboot, taking over from the 5.4 release, first released on +November 11th 2016. + +skiboot-5.5.0 contains all bug fixes as of :ref:`skiboot-5.4.3` +and :ref:`skiboot-5.1.19` (the currently maintained stable releases). + +For how the skiboot stable releases work, see :ref:`stable-rules` for details. + +This release is a good level set of POWER9 support for bringup activities. +If you are doing bringup, it is strongly suggested you continue to follow +skiboot master. + +After skiboot 5.5.0, we move to a regular six week release cycle, +similar to op-build, but slightly offset to allow for a short stabilisation +period. Expected release dates and contents are tracked using GitHub milestone +and issues: https://github.com/open-power/skiboot/milestones + +Changes in skiboot-5.5.0 +------------------------ + +See changes in the release candidates: + +- :ref:`skiboot-5.5.0-rc1` +- :ref:`skiboot-5.5.0-rc2` +- :ref:`skiboot-5.5.0-rc3` + +Changes since skiboot-5.5.0-rc3 +------------------------------- + +- hdat: parse processor attached i2c devices + + Adds basic parsing for i2c devices that are attached to the processor + I2C interfaces. This is mainly VPD SEEPROMs. +- libflash/blocklevel: Add blocklevel_smart_erase() + + With recent changes to flash drivers in linux not all erase blocks are + 4K anymore. While most level of the pflash/gard tool stacks were written + to not mind, it turns out there are bugs which means not 4K erase block + backing stores aren't handled all that well. Part of the problem is the + FFS layout that is 4K aligned and with larger block sizes pflash and the + gard tool don't check if their erase commands are erase block aligned - + which they are usually not with 64K erase blocks. + + This patch aims to add common functionality to blocklevel so that (at + least) pflash and the gard tool don't need to worry about the problem + anymore. +- external/pflash: Use blocklevel_smart_erase() +- external/gard: Use blocklevel_smart_erase() +- libstb/create-container: Add full container build and sign with imprint keys + + This adds support for writing all the public key and signature fields to the + container header, and for dumping the prefix and software headers so they may + may be signed, and for signing those headers with the imprint keys. +- asm: do not set SDR1 on POWER9. This register does not exist in ISAv3. + +Testing: + +- mambo: Allow setting the Linux command line from the environment + + For automated testing it's helpful to be able to set the Linux command + line via an environment variable. +- mambo: Add util function for breaking on console output + + +Contributors +------------ + +Processed 408 csets from 31 developers + +3 employers found + +A total of 24073 lines added, 16759 removed (delta 7314) + +Extending the analysis done for the last few releases, we can see our trends +in code review across versions: + +======== ====== ======= ======= ====== ======== +Release csets Ack Reviews Tested Reported +======== ====== ======= ======= ====== ======== +5.0 329 15 20 1 0 +5.1 372 13 38 1 4 +5.2-rc1 334 20 34 6 11 +5.3-rc1 302 36 53 4 5 +5.4.0 361 16 28 1 9 +5.5.0 408 11 48 14 10 +======== ====== ======= ======= ====== ======== + +I am absolutely *thrilled* as to the uptick of reviews and tested-by occuring +over our 5.4.0 release.
