It is *important* that you use --mtd if your + BMC may otherwise know how to interact with its own flash. +- support for Micron N25Q256Ax and N25Qx256Ax NOR flash. +- support for Winbond W25Q256BV NOR flash +- support for an emulated ("fake") RTC clock, useful in simulators + and during bringup +- Explicit 1:1 mapping in ranges properties have been added to PCI + bridges. This allows a neat trick with offb and VGA ports that should + probably not be told to young children. +- Added support to read the V2 format of the OCC-OPAL memory region, + which supports Workload Optimized Frequency (WOF) + +Changes in behavior: +- Assigning OPAL IDs to PHBs is now fixed and based on the chip id and PHB + index on that chip. On POWER7, we continue to use allocated numbers. +- We now query the BMC for BT capabilities rather than making assumptions + +Removed support: +- p5ioc2 is no longer supported. + This affects a grand total of two POWER7 systems in the world. +NOTE: It is planned that skiboot-5.2 will be the last release supporting +POWER7 machines. + +Bugs fixed: +- PHB3: Fix unexpected ER (all) on errinjct by PCI config +- hw/bt: timeout messages when BT interface isn't functional +- On Habanero, Slot3 should have been "Slot 3". +- We now completely flush the console buffer before power down and reboot +- For chips with ibm,occ-functional-state set to false, we don't wait + for the OCC to start. This caused needless delay in booting on simulators + which did not simulate OCCs. +- Change OCC reset order to always reset slave OCCs first. +- slw: Remove overwrites for EX_PM_CORE_ECO_VRET and EX_PM_CORE_PFET_VRET + (these were already initialized in hostboot) +- p8-i2c: send stop bit on timeouts. + Some devices can otherwise leave the bus in a held state. + +Other improvements include: +- many fixes of compiler and static analysis warnings +- increased unit test coverage +- Unit test of "boot debian jessie installer" +- ability to plug in other simulators to run existing tests (e.g. simulator for + non pegasus p8) +- Support using (patched) Qemu with PowerNV platform support for running + unit tests. +- increased support for running with sparse +- We now build with -fstack-protector-strong if supported by the compiler +- We now build with -Werror for -Wformat +- pflash is now built as part of travis-ci and for Coverity Scan. +- There is now a RPM SPEC file that can be used as the basis for packaging + skiboot and associated utilities. + +Contributors +------------ + +We have had a number of improvements in workflow over skiboot-5.1.0. Looking +back, we have roughly the same number of changesets (372 for 5.1.0, 334 for +5.2.0-rc1 - even closer for 5.1.0-beta1) which indicates a relatively stable +rate of development. + +Complete statistics are included below (generated by gitdm), but I'd like to +draw attention to a couple of stats: + +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 + +Overall, it looks like we're on the right trajectory for increasing the number +of eyeballs looking at code before it heads in tree, especially around testing. +Largely, this increase in Tested-by can be attributed to encouraging the +existing test teams to start commenting on the patches themselves. + +Anyway, here's the full stats from skiboot 5.1.0 to 5.2.0-rc1: + +Processed 334 csets from 27 developers +2 employers found +A total of 46172 lines added, 23274 removed (delta 22898) + +Developers with the most changesets +Stewart Smith 146 (43.7%) +Cyril Bur 52 (15.6%) +Benjamin Herrenschmidt 15 (4.5%) +Joel Stanley 12 (3.6%) +Gavin Shan 12 (3.6%) +Alistair Popple 10 (3.0%) +Vasant Hegde 10 (3.0%) +Michael Neuling 10 (3.0%) +Russell Currey 9 (2.7%) +Cédric Le Goater 8 (2.4%) +Jeremy Kerr 8 (2.4%) +Samuel Mendoza-Jonas 6 (1.8%) +Neelesh Gupta 6 (1.8%) +Shilpasri G Bhat 4 (1.2%) +Oliver O'Halloran 4 (1.2%) +Mahesh Salgaonkar 4 (1.2%) +Vipin K Parashar 3 (0.9%) +Daniel Axtens 3 (0.9%) +Andrew Donnellan 2 (0.6%) +Philippe Bergheaud 2 (0.6%) +Ananth N Mavinakayanahalli 2 (0.6%) +Vaibhav Jain 1 (0.3%) +Sam Mendoza-Jonas 1 (0.3%) +Adriana Kobylak 1 (0.3%) +Shreyas B.
