skiboot-6.0.14
|
|
==============
|
|
|
|
skiboot 6.0.14 was released on Tuesday November 27th, 2018. 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: ::
