Title:
Add processor support from SMBIOS 3.6.0 in Jammy and Noble
Status in dmidecode package in Ubuntu:
Fix Released
Status in dmidecode source package in Jammy:
In Progress
Status in dmidecode source package in Noble:
Fix Committed
Bug description:
[Impact]
* Add processor support from SMBIOS 3.6.0 in Jammy and Noble
to enable new hardware in LTS release per SRU policy [1].
* Backport of 1 relatively simple patch from dmidecode 3.6
in Oracular to dmidecode 3.3 in Jammy and dmidecode 3.5 in Noble
[Test Plan]
* Check no regressions on current systems with SMBIOS < 3.6,
i.e., no output changes in text and binary form.
$ sudo dmidecode > old.txt 2>&1
$ sudo dmidecode --dump-bin old.bin
$ apt install dmidecode # modified package
$ sudo dmidecode > new.txt 2>&1
$ sudo dmidecode --dump-bin new.bin
$ cmp old.txt new.txt; echo $?
0
$ cmp old.bin new.bin; echo $?
0
* Check for expected output on new systems with SMBIOS >= 3.6.
$ diff old.txt new.txt
1) Run "sudo dmidecode -t4"
2) Observe that the "Thread Enabled" field is being reported
[1] https://canonical-sru-docs.readthedocs-
hosted.com/en/latest/reference/requirements/#other-safe-cases
[Where problems could occur]
* The patch adds support for new bits/codes/strings,
so there are no changes expected for the old spec support.
* The new field (Thread Enabled) is added in a specific condition
and should not impact systems without support to it.
* If the current dmidecode is being used on systems that support
the new bits, users will see a different output, and this might
break some text parsers if they are strictly programmed. Using the
binary output is recommended in these cases.

dmidecode: Add processor support from SMBIOS 3.6.0
SMBIOS 3.6.0 adds the following to the Processor Information
structure (type 4):
* 9 socket types
* 1 processor family
* 1 field (Thread Enabled)
