Package: ndctl
Version: 71.1-1
Severity: serious
For Debian 11.5 32 bit, I got below info:
apt-cache search ndctl
libndctl-dev - Development files for libndctl
libndctl6 - Utility library for managing the libnvdimm subsystem
ndctl - Utility for managing the nvdimm subsystem
It is same to what I got from Debian 11.5 64 bit:
apt-cache search ndctl
libndctl-dev - Development files for libndctl
libndctl6 - Utility library for managing the libnvdimm subsystem
ndctl - Utility for managing the nvdimm subsystem
>From https://lists.debian.org/debian-devel/2016/12/msg00330.html,
>https://lists.debian.org/debian-devel/2016/12/msg00343.html, NVDIMM will be
>fully supported once OS has the package ndctl.
But I found that Debian 11.5 32 bit vm couldn’t recognize the NVDIMM device:
#cat /etc/debian_version
11.5
#uname -m
i686
# dmesg | grep -i bios-e820 | grep persistent
[ 0.000000] BIOS-e820: [mem 0x0000000240000000-0x000000043fffffff]
persistent (type 7)
# lsmod | grep -i pmem
# lsmod | grep -i nvdimm
The NVDIMM device has been added to Debian 11.5 32bit VM, and it appears in
BIOS-e820 table, but no NVDIMM modules were loaded and no PMem device is listed
For Debian 11.5 64 bit vm, I got below info:
# cat /etc/debian_version
11.5
# uname -m
x86_64
#dmesg | grep -i bios-e820 | grep persistent
[ 0.000000] BIOS-e820: [mem 0x0000000240000000-0x000000043fffffff]
persistent (type 7)
# lsmod | grep -i pmem
dax_pmem_compat 16384 0
device_dax 20480 1 dax_pmem_compat
nd_pmem 24576 0
dax_pmem_core 16384 1 dax_pmem_compat
nd_btt 28672 1 nd_pmem
libnvdimm 200704 5
dax_pmem_core,nd_btt,nd_pmem,dax_pmem_compat,nfit
# lsmod | grep -i nvdimm
libnvdimm 200704 5
dax_pmem_core,nd_btt,nd_pmem,dax_pmem_compat,nfit
So I’d like to confirm whether Debian 11.x 32 bit support NVDIMM or not. Your
reply would be appreciated.
Best regards,
Winnie Yue

So... as this report was framed as a question, and there's no follow-up
after Dan's explanation, I assume this is either solved or no longer
relevant. Please holler if anything...
