It is the fourth +release candidate of skiboot 5.10, which will become the new stable release +of skiboot following the 5.9 release, first released October 31st 2017. + +skiboot v5.10-rc4 contains all bug fixes as of :ref:`skiboot-5.9.8` +and :ref:`skiboot-5.4.9` (the currently maintained stable releases). There +may be more 5.9.x stable releases, it will depend on demand. + +For how the skiboot stable releases work, see :ref:`stable-rules` for details. + +The current plan is to cut the final 5.10 in February, with skiboot 5.10 +being for all POWER8 and POWER9 platforms in op-build v1.21. +This release will be targeted to early POWER9 systems. + +Over skiboot-5.10-rc3, we have the following changes: + +- core: Fix mismatched names between reserved memory nodes & properties + + OPAL exposes reserved memory regions through the device tree in both new + (nodes) and old (properties) formats. + + However, the names used for these don't match - we use a generated cell + address for the nodes, but the plain region name for the properties. + + This fixes a warning from FWTS +- sensor-groups: occ: Add support to disable/enable sensor group + + This patch adds a new opal call to enable/disable a sensor group. This + call is used to select the sensor groups that needs to be copied to + main memory by OCC at runtime. +- sensors: occ: Add energy counters + + Export the accumulated power values as energy sensors. The accumulator + field of power sensors are used for representing energy counters which + can be exported as energy counters in Linux hwmon interface. +- sensors: Support reading u64 sensor values + + This patch adds support to read u64 sensor values. This also adds + changes to the core and the backend implementation code to make this + API as the base call. Host can use this new API to read sensors + upto 64bits. + + This adds a list to store the pointer to the kernel u32 buffer, for + older kernels making async sensor u32 reads. +- dt: add /cpus/ibm,powerpc-cpu-features device tree bindings + + This is a new CPU feature advertising interface that is fine-grained, + extensible, aware of privilege levels, and gives control of features + to all levels of the stack (firmware, hypervisor, and OS). + + The design and binding specification is described in detail in doc/. +- phb3/phb4/p7ioc: Document supported TCE sizes in DT + + Add a new property, "ibm,supported-tce-sizes", to advertise to Linux how + big the available TCE sizes are. Each value is a bit shift, from + smallest to largest. +- phb4: Fix TCE page size + + The page sizes for TCEs on P9 were inaccurate and just copied from PHB3, + so correct them. +- Revert "pci: Shared slot state synchronisation for hot reset" + + An issue was found in shared slot reset where the system can be stuck in + an infinite loop, pull the code out until there's a proper fix. + + This reverts commit 1172a6c57ff3c66f6361e572a1790cbcc0e5ff37. +- hdata/iohub: Use only wildcard slots for pluggables + + We don't want to cause a VID:DID check against pluggable devices, as + they may use multiple devids. + + Narrow the condition under which VID:DID is listed in the dt, so that + we'll end up creating a wildcard slot for these instead. +- increase log verbosity in debug builds +- Add -debug to version on DEBUG builds +- cpu_wait_job: Correctly report time spent waiting for job |
