skiboot-6.2-rc2
|
||
|
|
===============
|
||
|
|
|
||
|
|
skiboot v6.2-rc2 was released on Thursday November 29th 2018. It is the second
|
||
|
|
release candidate of skiboot 6.2, which will become the new stable release
|
||
|
|
of skiboot following the 6.1 release, first released July 11th 2018.
|
||
|
|
|
||
|
|
Skiboot 6.2 will mark the basis for op-build v2.2.
|
||
|
|
|
||
|
|
skiboot v6.2-rc2 contains all bug fixes as of :ref:`skiboot-6.0.14`,
|
||
|
|
and :ref:`skiboot-5.4.10` (the currently maintained
|
||
|
|
stable releases).
|
||
|
|
|
||
|
|
For how the skiboot stable releases work, see :ref:`stable-rules` for details.
|
||
|
|
|
||
|
|
Over :ref:`skiboot-6.2-rc1`, we have the following changes:
|
||
|
|
|
||
|
|
- npu2-opencapi: Log extra information on link training failure
|
||
|
|
- npu2-opencapi: Detect if link trained in degraded mode
|
||
|
|
- platform/firenze: Fix branch-to-null crash
|
||
|
|
|
||
|
|
When the bus alloc and free methods were removed we missed a case in the
|
||
|
|
Firenze platform slot code that relied on the the bus-specific method to
|
||
|
|
the bus pointer in the request structure. This results in a
|
||
|
|
branch-to-null during boot and a crash. This patch fixes it by
|
||
|
|
initialising it manually here.
|
||
|
|
- 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
|
||
|
|
|
||
|
|
- libflash: Restore blocklevel tests
|
||
|
|
|
||
|
|
This fell out in f58be46 "libflash/test: Rewrite Makefile.check to
|
||
|
|
improve scalability". Add it back in as test-blocklevel.
|
||
|
|
- Warn on long OPAL calls
|
||
|
|
|
||
|
|
Measure entry/exit time for OPAL calls and warn appropriately if the
|
||
|
|
calls take too long (>100ms gets us a DEBUG log, > 1000ms gets us a
|
||
|
|
warning).
|
||
|
|
|
||
|
|
CI, testing, and utilities
|
||
|
|
--------------------------
|
||
|
|
|
||
|
|
- travis: Coverity fixed their SSL cert
|
||
|
|
- opal-ci: Use ubuntu:rolling for Ubuntu latest image
|
||
|
|
- ffspart: Add test for eraseblock size
|
||
|
|
- ffspart: Add toc test
|
||
|
|
- hdata/test: workaround dtc bugs
|
||
|
|
|
||
|
|
In dtc v1.4.5 to at least v1.4.7 there have been a few bugs introduced
|
||
|
|
that change the layout of what's produced in the dts. In order to be
|
||
|
|
immune from them, we should use the (provided) dtdiff utility, but we
|
||
|
|
also need to run the dts we're diffing against through a dtb cycle in
|
||
|
|
order to ensure we get the same format as what the hdat_to_dt to dts
|
||
|
|
conversion will.
|
||
|
|
|
||
|
|
This fixes a bunch of unit test failures on the version of dtc shipped
|
||
|
|
with recent Linux distros such as Fedora 29.
