skiboot-5.1.0-beta1
===================
skiboot-5.1.0-beta1 was released on July 21st, 2015.
skiboot-5.1.0-beta1 is the first beta release of skiboot 5.1, which will
become a new stable release, replacing skiboot-5.0 (released April 14th 2015)
Skiboot 5.1-beta1 contains all fixes from skiboot-5.0 stable branch up to
skiboot-5.0.5.
New features
^^^^^^^^^^^^
Over skiboot-5.0, the following features have been added:
* Centaur i2c support
* Add Naples chip (CPU, PHB, LPC serial interrupts) support
* Added qemu platform
* improvements to FSI error handling
* improvements in chip TOD failover (some only on FSP systems)
* Set Relative Priority Register (RPR) to recommended value
* this affects thread priority in SMT modes
* greatly reduce memory consumption by CPU stacks for non-present CPUs
* Previously we would reserve enough memory for max PIR for each CPU type.
* This fix frees up 77MB of RAM on a typical P8 system.
* increased OPAL API documentation
* Asynchronous preloading of resources from FSP/flash
* improves boot time on some systems
* Basic Garrison platform support
* Add Mambo platform (P8 Functional Simulator, systemsim)
* includes fake NVRAM, RTC
* Support building with GCOV, increasing memory for skiboot binary to 2MB
* includes boot code coverage testing
* Increased skiboot HEAP size.
* We are not aware of any system where you would run out, but on large
systems it was getting closer than we liked.
* add boot_tests.sh for helping automate boot testing on FSP and BMC machines
* Versioning of pflash and gard utilities to help Linux (or other OS)
distributions with packaging.
* OCC throttle status messages to host
* CAPP timebase sync ("ibm,capp-timebase-sync" in DT to indicate CAPP timebase
was synced by OPAL)
New features for FSP based machines
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* in-band IPMI support
* ethernet adaptor location codes
* add DIMM frequency information to device tree
* improvements in FSP error log code paths
* fix some boot time memory leaks
* harmless to end user
New features for AMI BMC based machines
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* PCIe power workaround for K80
* Added support for Macronix 128Mbit flash chips
* Initial PRD support for Firestone platform
* improved reliability when BMC reboots
Bug Fixes
^^^^^^^^^
The following bugs have been fixed:
* Increase PHB3 timeout for electrical links coming up to 2 seconds.
* fixes issues with some Mellanox cards
* Hang in opal_reinit_cpus() that could prevent kdump from functioning
* PHB3: fix crash in phb3_init
* PHB3: fix crash with fenced PHB in phb3_init_hw()
* Fix bugs in hw/bt.c (interface for IPMI on BMC machines) that could possibly
lead to a crash (dereferencing invalid address, deadlock)
* ipmi/sel: fix use-after-free
* Bug fixes in EEH handling
* opal_pci_next_error() cleared OPAL_EVENT_PCI_ERROR unconditionally, possibly leading to missed errors.
FSP-specific bugs fixed:
^^^^^^^^^^^^^^^^^^^^^^^^
* (also fixed in skiboot-5.0.2) Fix race in firenze_get_slot_info() leading to
assert() with many PCI cards
With many PCI cards, we'd hit a race where calls to
firenze_add_pcidev_to_fsp_inventory would step on each other leading to
memory corruption and finally an assert() in the allocator being hit
during boot.
* PCIe power workaround for K80 cards
* /ibm,opal/led renamed to /ibm,opal/leds in Device Tree
* compatible change as no FSP based systems shipped with skiboot-5.0
General improvements:
^^^^^^^^^^^^^^^^^^^^^
* don't run pollers on non-boot CPUs in time_wait
* improvements to opal-prd, pflash, libflash
* including new blocklevel interface in libflash
* many minor fixes to issues found by static analysis
* improvements in FSP error log code paths
* code cleanup in memory allocator
* Don't expose individual nvram partitions in the device tree, just the whole
flash device.
* build improvements for building on ppc64el host
* improvements in cpu_relax() for idle threads, needed for GCOV on large
machines.
* Optimized memset() for POWER8, greatly reducing number of instructions
executed for boot, which helps boot time in simulators.
* Major improvements in hello_world kernel
* Bloat of huge 17 instruction test case reduced to 10.
* Disable bust_locks for general calls of abort()
* Should enable better error messages during abort() when other users of
LPC bus exist (e.g. flash)
