| skiboot-5.2.0 |
| ============= |
| |
| skiboot-5.2.0 was released on Wednesday March 16th, 2016. |
| |
| skiboot-5.2.0 is the first stable release of skiboot 5.2, the new stable |
| release of skiboot, which will take over from the 5.1.x series which was |
| first released August 17th, 2015. |
| |
| skiboot-5.2.0 contains all bug fixes as of skiboot-5.1.15. |
| |
| This is the second release that will follow the (now documented) Skiboot |
| stable rules - see :ref:`stable-rules`. |
| |
| Changes since rc2 |
| ----------------- |
| Over skiboot-5.2.0-rc2, the following fixes are included: |
| |
| - Include 'extract-gcov' in make clean. |
| - ipmi-sel: Fix esel event logger to handle early boot PANIC events |
| - IPMI: Enable synchronous eSEL logging option (for PANIC events) |
| - libflash/libffs: Reporting seeing all 0xFF bytes during init. |
| - ipmi-sel: Fix memory leak in error path |
| |
| Changes since rc1 |
| ----------------- |
| Over skiboot-5.2.0-rc1, we have the following changes: |
| |
| - Add Barreleye platform |
| |
| Generic |
| ^^^^^^^ |
| |
| - hw/p8-i2c: Speed up SMBUS_WRITE |
| - Fix early backtraces |
| |
| FSP Platforms |
| ^^^^^^^^^^^^^ |
| |
| - fsp-sensor: rework device tree for sensors |
| - platforms/firenze: Fix I2C clock source frequency |
| |
| Simics simulator |
| ^^^^^^^^^^^^^^^^ |
| |
| - Enable Simics UART console |
| |
| Mambo simulator |
| ^^^^^^^^^^^^^^^ |
| |
| - platforms/mambo: Add terminate callback |
| |
| - fix hang in multi-threaded mambo |
| - add multithreaded mambo tests |
| |
| IPMI |
| ^^^^ |
| |
| - hw/ipmi: fix event data 1 for System Firmware Progress sensor |
| - ipmi: Log exact NetFn value in OPAL logs |
| |
| AST BMC based platforms |
| ^^^^^^^^^^^^^^^^^^^^^^^ |
| |
| - hw/bt: allow BT driver to use different buffer size |
| |
| opal-prd utility |
| ^^^^^^^^^^^^^^^^ |
| |
| - opal-prd: Add debug output for firmware-driven OCC events |
| We indicate when we have a user-driven event, so add corresponding |
| outputs for firmware-driven ones too. |
| |
| getscom utility |
| ^^^^^^^^^^^^^^^ |
| |
| - Add Naples chip support |
| |
| New Features |
| ^^^^^^^^^^^^ |
| Over skiboot-5.1, the following features have been added: |
| |
| - Naples (P8', i.e. P8 with NVLINK) processor support, including NVLINK. |
| - Improvements in gard, libflash/pflash and opal-prd utilities |
| |
| - increased testing |
| - increased usability |
| - systemd scripts for opal-prd |
| - pflash can now use the /dev/mtd device to access BMC flash rather than |
| accessing it directly. 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 |
| ^^^^^^^^^^^^^^^^^^ |
| |
| - 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) |
