[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 * Possibly perform synthetic testing with crafted C structures. [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]. [1] https://wiki.ubuntu.com/StableReleaseUpdates#Other_safe_cases [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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dmidecode/+bug/1986852/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
