1.4.0
Changes:
- Added SMT support by properly differentiating between cores and CPUs.
I.e. switched from qc_num_cpu_* to qc_num_core_* attributes in layers
CEC, LPAR, ZVM_HYPERVISOR and KVM_HYPERVISOR.
NOTE: qc_num_cpu_* attributes remain to be valid in these cases to
preserve backwards compatibility for now. This will be removed in
one of the next releases! It is recommended to switch to the new
attributes _now_ and test with CONFIG_V1_COMPATIBILITY disabled!
- Added new attributes qc_num_threads_cp and qc_num_threads_ifl to layers
CEC, LPAR and ZVM_HYPERVISOR.
- Deprecated attribute qc_mobility_eligible (remains valid for now) and
replaced with qc_mobility_enabled to match z/VM terminology. Likewise
switched QC_LAYER_TYPE_ZVM_CPU_POOL to QC_LAYER_TYPE_ZVM_RESOURCE_POOL.
- Moved build customization defines (e.g. CONFIG_V1_COMPATIBILITY) to
query_capacity.h.
- Don't build with textual hypfs per default anymore due to unrecoverable
issues (see section 'Bug fixes'). Since all Linux distributions ship
with debugfs (providing binary hypfs support), overriding textual hypfs,
for years, this change will hardly ever be noticable. Enable define
CONFIG_TEXTUAL_HYPFS in query_capacity.h to revert.
Note that textual hypfs support will be removed in a future release.

Bug fixes:
- Added an exception to consistency check to ignore inconsistencies between
textual hypfs and STHYI for attributes qc_num_cp_total and
qc_num_ifl_total in the LPAR layer.
Background: Textual hypfs cannot tell whether a core is configured or
not. It therefore reports all cores as configured, which can
be wrong.
