6skiboot v5.10-rc4 was released on Wednesday February 21st 2018. It is the fourth
7release candidate of skiboot 5.10, which will become the new stable release
8of skiboot following the 5.9 release, first released October 31st 2017.
9
10skiboot v5.10-rc4 contains all bug fixes as of :ref:`skiboot-5.9.8`
11and :ref:`skiboot-5.4.9` (the currently maintained stable releases). There
12may be more 5.9.x stable releases, it will depend on demand.
13
14For how the skiboot stable releases work, see :ref:`stable-rules` for details.
15
16The current plan is to cut the final 5.10 in February, with skiboot 5.10
17being for all POWER8 and POWER9 platforms in op-build v1.21.
18This release will be targeted to early POWER9 systems.
19
20Over skiboot-5.10-rc3, we have the following changes:
21
22- core: Fix mismatched names between reserved memory nodes & properties
23
24  OPAL exposes reserved memory regions through the device tree in both new
25  (nodes) and old (properties) formats.
26
27  However, the names used for these don't match - we use a generated cell
28  address for the nodes, but the plain region name for the properties.
29
30  This fixes a warning from FWTS
31- sensor-groups: occ: Add support to disable/enable sensor group
32
33  This patch adds a new opal call to enable/disable a sensor group. This
34  call is used to select the sensor groups that needs to be copied to
35  main memory by OCC at runtime.
36- sensors: occ: Add energy counters
37
38  Export the accumulated power values as energy sensors. The accumulator
39  field of power sensors are used for representing energy counters which
40  can be exported as energy counters in Linux hwmon interface.
41- sensors: Support reading u64 sensor values
42
43  This patch adds support to read u64 sensor values. This also adds
44  changes to the core and the backend implementation code to make this
45  API as the base call. Host can use this new API to read sensors
46  upto 64bits.
47
48  This adds a list to store the pointer to the kernel u32 buffer, for
49  older kernels making async sensor u32 reads.
50- dt: add /cpus/ibm,powerpc-cpu-features device tree bindings
51
52  This is a new CPU feature advertising interface that is fine-grained,
53  extensible, aware of privilege levels, and gives control of features
54  to all levels of the stack (firmware, hypervisor, and OS).
55
56  The design and binding specification is described in detail in doc/.
57- phb3/phb4/p7ioc: Document supported TCE sizes in DT
58
59  Add a new property, "ibm,supported-tce-sizes", to advertise to Linux how
60  big the available TCE sizes are.  Each value is a bit shift, from
61  smallest to largest.
62- phb4: Fix TCE page size
63
64  The page sizes for TCEs on P9 were inaccurate and just copied from PHB3,
65  so correct them.
66- Revert "pci: Shared slot state synchronisation for hot reset"
67
68  An issue was found in shared slot reset where the system can be stuck in
69  an infinite loop, pull the code out until there's a proper fix.
70
71  This reverts commit 1172a6c57ff3c66f6361e572a1790cbcc0e5ff37.
72- hdata/iohub: Use only wildcard slots for pluggables
73
74  We don't want to cause a VID:DID check against pluggable devices, as
75  they may use multiple devids.
76
77  Narrow the condition under which VID:DID is listed in the dt, so that
78  we'll end up creating a wildcard slot for these instead.
79- increase log verbosity in debug builds
80- Add -debug to version on DEBUG builds
81- cpu_wait_job: Correctly report time spent waiting for job
