|
||
| Skiboot 5.0 was released Friday 10th April 2015. | ||
|
|
||
| Changes in 5.0 (since rc3): | ||
|
|
||
| - Fix chip id for nx coprocessors. | ||

|
|
||
| - add support for cec_power_down on mambo | ||

| - set NX crb input queues to 842 only | ||
| - core: Catch attempts to branch through a NULL pointer | ||
| - plat/firestone: Add missing platform hooks | ||
| - plat/firestone: Add missing platform hooks | ||
| - elog: Don't call uninitialized platform elog_commit | ||
| - external/opal-prd: Use "official" switch-endian syscall | ||
| - hw/ipmi: Rework sensors and fix boot count sensor | ||
|
|
||
| Changes in rc1 (since 4.1.1): | ||
|
|
||
| General: | ||
|
|
||
| * big OPAL API documentation updates | ||
| We now document around 19 OPAL calls. There's still ~100 left to doc | ||
| though :) | ||
| * skiboot can load FreeBSD kernel payload (thanks to Nathan Whitehorn) | ||
| * You can now run sparse by setting C=1 when building | ||
| * PSI: Revert the timeout for PSI link recovery to architected value | ||
| now 30mins (prev 15) | ||
| * cpuidle: Add validated metrics for idle states | ||
| * core/flash: Add flash API | ||
| OPAL_FLASH_(READ|WRITE|ERASE) | ||
| * capi: Dynamically calculate which CAPP port to use | ||
| no longer hardwired to PHB0 | ||
| * vpd: Use slca parent-child relationship to create vpd tree | ||
| * opal: Do not overwrite same HMI event for multiple HMI errors. | ||
| Now Linux will get a HMI event for each HMI error | ||
| * HMI event v2 now includes information about checkstop | ||
| * HMI improvements, handle more conditions gracefully: | ||
|
|
||
| * TB residue error | ||
| * TFMR firmware control error | ||
| * TFMR parity | ||
| * TFMR HDEC parity error | ||
| * TFMR DEC parity error | ||
| * TFMR SPURR/PURR parity error | ||
| * TB residue and HDEC parity HMI errors on split core | ||
| * hostservices: Cache lids prior to first load request | ||
| * Warn when pollers are called with a lock held | ||
| and keep track of lock depth. | ||
|
|
||
| **NOTE:** This means we will get backtraces in skiboot msglog on FSP machines | ||
| This is a KNOWN ISSUE and is largely harmless. | ||
| There's still a couple that we haven't yet cleaned, these | ||
| messages can be thought of as a TODO list for developers. | ||
|
|
||
| * Don't run pollers in time_wait if lock held | ||
| * pci: Don't hang if we have only one CPU | ||
| * Detect recursive poller entry | ||
| * General cleanup | ||
| * Cleanup of opal.h so that we can have Linux and skiboot match | ||
| * add sparse annotations to opal.h | ||
| * Platform hooks for loading and preloading resources (LIDs) | ||
| This lays the groundwork for cutting 4-20 seconds off boot in a | ||
| future skiboot release. | ||
| * Fix potential race when clearing OCC interrupt status | ||
| * Add platform operation for reading sensors | ||
|
|
||
| * add support to read core and memory buffer temperatures | ||
|
|
||
| Mambo/POWER8 Functional Simulator: | ||
|
|
||
| * Replace is_mambo_chip() with a better quirks mechanism. | ||
| * Don't hang if we only have one CPU and PCI. | ||
|
|
||
| BMC systems: | ||
|
|
||
| * BMC can load payload from flash | ||
| * IPMI on BMC systems: graceful poweroff and reboot | ||
| * IPMI on BMC systems: watchdog timer support | ||
| * IPMI on BMC systems: PNOR locking | ||
| * Support for IPMI progress sensor | ||
| * IPMI boot count sensor | ||
| * capi: Rework microcode flash download and CAPP upload | ||
| load microcode on non-fsp systems | ||
| * NEW opal-prd userspace tool that handles PRD on non-FSP systems. | ||
| and OPAL PRD calls to support it. | ||
| * Improvements to opal-prd, libflash, and ipmi | ||
| * ECC support in libflash | ||
| * Load CAPI micro code, enabling CAPI on OpenPower systems. | ||
| * Dynamically calculate which CAPP port to use, don't hardcode to PHB0 | ||
| * memboot flash backend | ||
|
|
||
| POWER8 | ||
|
|
||
| * add nx-842 coproc support | ||
|
|
||
| FSP systems: | ||
|
|
||
| * Make abort() update sp attn area (like assert does) | ||
| On FSP systems this gives better error logs/dumps when abort() is hit | ||
| * FSP/LEDS: Many improvements and bug fixes | ||
| * LED support for FSP machines | ||
| Adds OPAL_LEDS_(GET|SET)_INDICATOR and device-tree bindings | ||
| * Refactor of fsp-rtc | ||
| * OCC loading fixes, including possible race condition where we would | ||
| fail to IPL. | ||
|
|
||
| POWER7 | ||
|
|
||
| * Fix unsupported return code of OPAL_(UN)REGISTER_DUMP_REGION on P7 | ||
| * occ: Don't do bad XSCOMs on P7 | ||
| The OCC interrupt register only exists on P8, accessing it on P7 causes | ||
| not only error logs but also causes PRD to eventually gard chips. | ||
| * cpu: Handle opal_reinit_cpus() more gracefully on P7 | ||
| no longer generate error logs | ||
| * libflash updates for openpower | ||
| * misc code cleanup | ||
| * add nx-842 coproc support |
