Title:
[Bionic] ACPI / PPTT: use ACPI ID whenever
ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Bionic:
Fix Released
Bug description:
[Impact]
Currently, we use the ACPI processor ID only for the leaf/processor nodes as
the specification states it must match the value of the ACPI processor ID field
in the processor’s entry in the MADT.
However, if a PPTT structure represents a processors group, it matches
a processor container UID in the namespace and the
ACPI_PPTT_ACPI_PROCESSOR_ID_VALID flag indicates whether the ACPI
processor ID is valid.
Let's use UID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set to be
consistent instead of using table offset as it's currently done for
non-leaf nodes.

[Kernel-packages] [Bug 1797200] Re: [Bionic] ACPI / PPTT: use ACPI ID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
bionic' to 'verification-done-bionic'. If the problem still exists,
change the tag 'verification-needed-bionic' to 'verification-failed-
bionic'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!
