Verification done on jammy-proposed.

1) a system/hardware vendor tested and confirmed that:
   - systems with SMBIOS 3.5 report the new fields as expected;
   - systems with SMBIOS < 3.4 keep the old fields as expected.

2) I tested on several physical and virtual machines, and:
   - systems with SMBIOS < 3.4 keep the old fields as expected.
     (see details below and in next comment.)

Physical machines:
- Supermicro AS -2024US-TRT
- Dell PowerEdge R730xd
- HP ProLiant SL390s G7
- HP ProLiant DL360e Gen8
- HP ProLiant DL360 Gen9

Virtual machines:
- Multipass VM
- LXD VM
- OpenStack VM

cheers,

Title:
  Support SMBIOS 3.4 and 3.5 in Jammy for Hardware Enablement

Status in dmidecode package in Ubuntu:
  Fix Released
Status in dmidecode source package in Jammy:
  Fix Committed
Status in dmidecode source package in Kinetic:
  Fix Released

Bug description:
  [Impact]

   * Support the SMBIOS 3.4 and 3.5 specifications in Jammy
     to enable new hardware in LTS release per SRU policy [1].

   * Backport of 15 relatively simple patches from dmidecode 3.4
     in Kinetic to dmidecode 3.3 in Jammy (vs. 49 for full version).

   * Patches are detailed below.

  [Test Plan]

   * Check no regressions on current systems with SMBIOS < 3.4,
     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 >= 3.4.

     $ diff old.txt new.txt
     ...
     < # SMBIOS implementations newer than version 3.3.0 are not
     < # fully supported by this version of dmidecode.
     ...
     < Unknown Type
     <       Header and Data:
     ...
     > Firmware Inventory Information
     >       Firmware Component Name: BMC Firmware
     ...
     <       Type: <OUT OF SPEC>
     ---
     >       Type: DDR5
     ...
     <       Upgrade: <OUT OF SPEC>
     ---
     >       Upgrade: Socket LGA4677
     ...
     < Unknown Type
     <       Header and Data:
     ...
     > Firmware Inventory Information
     >       Firmware Component Name: BIOS Firmware

  [Where problems could occur]

   * Mostly the patches add support for new bits/codes/strings,
     so there's no changes expected for the old spec support,
     but some patches lightly change things a little bit (but
     only one should change a string, as far as I could tell).

   * So, theoretically, parsers that expect a very precise
     and constant format/string might have issues *in case*
     the changes introduced any. (But such tools maybe are
     already using the binary form anyway, for more detail.)

  [Other info]

    * No additional fixes upstream to the included patches.
      (The git repo's commits have the 'Fixes:' tag usage.)
      There's only 2 more commits after dmidecode-3-4 now.

  [Original Description]

  Backport the support for SMBIOS 3.4 and 3.5 specifications
  in Ubuntu Kinetic (dmidecode 3.4) to Jammy (dmidecode 3.3)
  to enable new hardware in the LTS release per SRU policy [1].

  [Patchset Details]

  Patches 1-8,10-11 are for SMBIOS 3.4;
  Patches 9,12-14 are for SMBIOS 3.5;
  Patch 15 updates supported version.

  01: SMBIOS 3.4: add new codes/strings for memory device type
  02: SMBIOS 3.4: add new codes/strings for processor socket
  03: SMBIOS 3.4: add new codes/strings for slot characteristics
  04: SMBIOS 3.4: add new codes/strings for memory device speed [string backward-compatible changes]
  05: SMBIOS 3.4: add new codes/strings for slot types [changes append '(U.2)' to 'PCI Express {2,3} SFF-8639' per spec]
  06: SMBIOS 3.4: add new codes/strings for processor characteristics
  07: SMBIOS 3.4: fix for patches 5-6
  08: SMBIOS 3.4: add support for ARM64 Processor ID field based on arch call [string backward-compatible changes]

  09: SMBIOS 3.5: add new codes/strings for processor socket
  10: SMBIOS 3.4* prep for patch 11 [string backward-compatible changes]
  11: SMBIOS 3.4* add new codes/strings for slot types [string backward-compatible changes]
  12: SMBIOS 3.5: add new codes/strings for manufacturing mode, pointing devices, onboard devices; introduce slot height
  13: SMBIOS 3.5: introduce firmware inventory information (characteristics, state, components
  14: SMBIOS 3.5: add new codes/strings for dmi types
  15: SMBIOS 3.5: set suppported smbios version to 3.5 (straight from 3.3)
