skiboot-6.0.17
|
|
==============
|
|
|
|
skiboot 6.0.17 was released on Wednesday February 20th, 2019. It replaces
|
|
:ref:`skiboot-6.0.16` as the current stable release in the 6.0.x series.
|
|
|
|
It is recommended that 6.0.17 be used instead of any previous 6.0.x version
|
|
due to the bug fixes it contains.
|
|
|
|
Bug fixes included in this release are:
|
|
|
|
- core/opal: Print PIR value in exit path, which is useful for debugging.
|
|
- core/ipmi: Improve error message
|
|
- hdata: Fix dtc warnings
|
|
|
|
Fix dtc warnings related to mcbist node ::
|
|
|
|
Warning (reg_format): "reg" property in /xscom@623fc00000000/mcbist@1 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)
|
|
Warning (reg_format): "reg" property in /xscom@623fc00000000/mcbist@2 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)
|
|
Warning (reg_format): "reg" property in /xscom@603fc00000000/mcbist@1 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)
|
|
Warning (reg_format): "reg" property in /xscom@603fc00000000/mcbist@2 has invalid length (4 bytes) (#address-cells == 1, #size-cells == 1)
|
|
|
|
Ideally we should add proper xscom range here... but we are not getting that
|
|
information in HDAT today. Lets fix warning until we get proper data in HDAT.
|
|
- 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.
|
|
- firmware-versions: Add test case for parsing VERSION
|
|
|
|
Also make it possible to use with afl-lop/afl-fuzz just to help make
|
|
*sure* we're all good.
|
|
|
|
Additionally, if we hit a entry in VERSION that is larger than our
|
|
buffer size, we skip over it gracefully rather than overwriting the
|
|
stack. This is only a problem if VERSION isn't trusted, which as of
|
|
4b8cc05a94513816d43fb8bd6178896b430af08f it is verified as part of
|
|
Secure Boot.
|
|
- core/cpu: HID update race
|
|
|
|
If the per-core HID register is updated concurrently by multiple
|
|
threads, updates can get lost. This has been observed during fast
|
|
reboot where the HILE bit does not get cleared on all cores, which
|
|
can cause machine check exception interrupts to crash.
|
|
|
|
Fix this by only updating HID on thread0.
|
|
- cpufeatures: Always advertise POWER8NVL as DD2
|
|
|
|
Despite the major version of PVR being 1 (0x004c0100) for POWER8NVL,
|
|
these chips are functionally equalent to P8/P8E DD2 levels.
|
|
|
|
This advertises POWER8NVL as DD2. As the result, skiboot adds
|
|
ibm,powerpc-cpu-features/processor-control-facility for such CPUs and
|
|
the linux kernel can use hypervisor doorbell messages to wake secondary
|
|
threads; otherwise "KVM: CPU %d seems to be stuck" would appear because
|
|
of missing LPCR_PECEDH.
