RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description fuguangzhe 2019-01-10 03:17:02 UTC 
Description of problem:
I use dmidecode tool to check AEP info in rhel7.6 GA
The value is 0x1F in MemoryType (offset 0x12h) 
The memory device type is defined in SMBIOS V3.2 Specification as below:
...
1Fh  Logical non-volatile device 
it seems that dmidecode doesn't support it in v3.1
this is the new item in SMBIOS V3.2.


shell>> dmidecode -t 17
...
Tyoe: <OUT OF SPEC>
...
Version-Release number of selected component (if applicable):
RHEL-7.6-20181010.0-Server-x86_64-dvd1.iso
kernel version:kernel-3.10.0-957.el7.x86_64
dmidecode: dmidecode-3.1-2.el7.x86_64

How reproducible:
shell>> dmidecode -t 17
...
Tyoe: <OUT OF SPEC>
...



Actual results:

shell>> dmidecode -t 17
...
Tyoe: <OUT OF SPEC>
...
Expected results:

shell>> dmidecode -t 17
...
Tyoe: Logical non-volatile device
...

commit 74dfb854b8199ddb0a27e89296fa565f4706cb9d
Author: Jean Delvare <jdelvare>
Date:   Wed Jan 16 09:04:55 2019 +0100

    dmidecode: Add "Logical non-volatile device" to the memory device types
    
    When adding support for non-volative memory, we forgot to add
    "Logical non-volatile device" to the list of memory types. This
    causes NVDIMM modules to show up as <OUT OF SPEC>. Fix the problem
    by adding the missing enumerated value.

Hi, Yutzuting

Could you help me dump the bin file? I could use this bin file to debug it.

Thanks.

Hi, fuguangzhe

It's too late to fix this bug on rhel7.7, so this bug will be deferred to rhel7.8.

Thanks.
Comment 6 lijiang 2019-02-22 08:31:47 UTC 
Here is a scratch build package(dmidecode-3.2-3.el7.x86_64.rpm) and i did a test as below, it can work well.

Scratch build: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=20324584

This is a scratch build package for rhel7.7. This package is only used for test.
Once i get all acks, it will be rebuilt for release.

I confirmed the fix has been included in RHEL7.7.
Comment 18 Jeff Bastian 2019-06-26 18:37:51 UTC 
Fuguangzhe and Adrian, thank you for testing!  (See comment 10 and comment 14.)

I don't have access to a system with AEP NVDIMM hardware, but I was able to test and verify with the attached AEP.dmi dump file.
