It replaces +:ref:`skiboot-6.0.13` as the current stable release in the 6.0.x series. + +It is recommended that 6.0.14 be used instead of any previous 6.0.x version +due to the bug fixes it contains. + +Bug fixes included in this release are: + +- libflash: Don't merge ECC-protected ranges + + Libflash currently merges contiguous ECC-protected ranges, but doesn't + check that the ECC bytes at the end of the first and start of the second + range actually match sanely. More importantly, if blocklevel_read() is + called with a position at the start of a partition that is contained + somewhere within a region that has been merged it will update the + position assuming ECC wasn't being accounted for. This results in the + position being somewhere well after the actual start of the partition + which is incorrect. + + For now, remove the code merging ranges. This means more ranges must be + held and checked however it prevents incorrectly reading ECC-correct + regions like below: :: + + [ 174.334119453,7] FLASH: CAPP partition has ECC + [ 174.437349574,3] ECC: uncorrectable error: ffffffffffffffff ff + [ 174.437426306,3] FLASH: failed to read the first 0x1000 from CAPP partition, rc 14 + [ 174.439919343,3] CAPP: Error loading ucode lid. index=201d1 + +- ipmi: Reduce ipmi_queue_msg_sync() polling loop time to 10ms. + + On a plain boot with hiomap, this reduces the time spent in OPAL + by ~170ms on p9dsu. This is due to hiomap (currently) using + synchronous IPMI messages. + + It will also *significantly* reduce latency on runtime flash + operations with hiomap, as we'll spend typically 10-20ms in OPAL + rather than 100-200ms. It's not an ideal solution to that, but + it's a quick and obvious win for jitter. + +- opal-prd: Fix opal-prd crash + + Crash log without this patch: :: + + opal-prd[2864]: unhandled signal 11 at 0000000000029320 nip 00000 00102012830 lr 0000000102016890 code 1 |
