| skiboot-5.5.0 |
| ============= |
| |
| skiboot-5.5.0 was released on Friday April 7th 2017. 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 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 |

| I am absolutely *thrilled* as to the uptick of reviews and tested-by occuring |
| over our 5.4.0 release. Although we are not yet back up to 5.3 era levels for |
| review, we're much closer. For tested-by, we've set a new record, which is |
| excellent! |
