| 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) |
