| skiboot-5.1.0-beta2 |
| =================== |
| |
| skiboot-5.1.0-beta2 was released on August 14th, 2015. |
| |
| skiboot-5.1.0-beta2 is the second beta release of skiboot 5.1, which will |
| become a new stable release, replacing skiboot-5.0 (released April 14th 2015) |
| |
| Skiboot 5.1.0-beta2 contains all fixes from skiboot-5.0 stable branch up to |
| skiboot-5.0.5 and everything from 5.1.0-beta1. |
| |
| New Features |
| ^^^^^^^^^^^^ |
| |
| Over skiboot-5.1.0-beta1, the following features have been added: |
| |
| - opal-api: Add OPAL call to handle abnormal reboots. |
| OPAL_CEC_REBOOT2 |
| Currently it will support two reboot types (0). normal reboot, that |
| will behave similar to that of opal_cec_reboot() call, and |
| (1). platform error reboot. |
| |
| Long term, this is designed to replace OPAL_CEC_REBOOT. |
| |
| Bug fixes |
| ^^^^^^^^^ |
| Over skiboot-5.1.0-beta1, the following bugs have been fixed: |
| |
| - external/opal-prd: Only map each PRD range once |
| |
| - could eventually lead to failing to map PRD ranges |
| - On skiboot crash, don't try to print symbol when we didn't find one |
| |
| - makes backtrace prettier |
| - On skiboot crash, dump hssr0 and hsrr1 registers correctly. |
| - Better support old and biarch compilers |
| |
| - test "new" compiler flags before using them |
| - Specify -mabi=elfv1 if supported (which means it's needed) |
| - fix boot-coverage-report makefile target |
| - ipmi: Fix the opal_ipmi_recv() call to handle the error path |
| |
| - Could make kernel a sad panda when in continues with other IPMI commands |
| - IPMI: truncate SELs at 2kb |
| |
| - it's the limit of the astbmc. We think. |
| - IPMI/SEL/PEL: |
| |
| - As per PEL spec, we should log events with severity >= 0x22 and "service |
| action flag" is "on". But in our case, all logs OPAL originagted logs |
| are makred as report externally. |
| We now only report logs with severity >= 0x22 |
| - IPMI: fixes to eSEL logging |
| - hw/phb3: Change reserved PE to 255 |
| |
| - Currently, we have reserved PE#0 to which all RIDs are mapped prior |
| to PE assignment request from kernel. The last M64 BAR is configured |
| to have shared mode. So we have to cut off the first M64 segment, |
| which corresponds to reserved PE#0 in kernel. If the first BAR |
| (for example PF's IOV BAR) requires huge alignment in kernel, we |
| have to waste huge M64 space to accommodate the alignment. If we |
| have reserved PE#256, the waste of M64 space will be avoided. |
| |
| Other changes |
| ^^^^^^^^^^^^^ |
| - unified version numbers for bundled utilities |
| - external/boot_test/boot_test.sh |
| |
| - better usable for automated boot testing |
