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:
Incomplete
Status in dmidecode source package in Noble:
Incomplete
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
