Public bug reported:
[Impact]
Applications, particularly those in the HPC domain (e.g. openmpi), can be
optimized for the processor and cache topology. However, the ARM CPU topology
isn't correctly exposed to userspace.
[Fix]
The ACPI 6.2 specification introduced a Processor Properties Topology Table
(PPTT). The linux kernel needs support for parsing this table, and exposing the
parsed topology to userspace. This is currently a work-in-progress upstream.
[Test Case]
TBD
[Regression Risk]
TBD
** Affects: linux (Ubuntu)
Importance: Undecided
Status: Incomplete
