PM961 NVMe PCIe Samsung SSD not supported? [Solved in Porteus 4.0]

Please reproduce your error on a second machine before posting, and check the error by running without saved changes or extra modules (See FAQ No. 13, "How to report a bug"). For unstable Porteus versions (alpha, beta, rc) please use the relevant thread in our "Development" section.

PM961 NVMe PCIe Samsung SSD not supported? [Solved in Porteus 4.0]

Post#1 by rych » 03 Nov 2017, 03:49

A M.2 PCIe NVMe SSD host system disk is not seen by Porteus 3.2.2 64. At all. Not in GParted, not anywhere.

Specifically, a new machine that we got is Dell Optiplex 7450 AIO, featuring a novel PM961 NVMe Samsung SSD disk. In Bios, under devices, it is listed not as a SATA disk but as a "M.2 PCIe SSD".

Although an expected development in disk drive design (SSD didn't need to be enclosed in SATA after all), I think it's too novel for porteus (linux?) to handle. Some help please.

could be like this?: https://bbs.archlinux.org/viewtopic.php?id=204629
their solution seems to be something to do with switching SATA operations from RAID to AHCI in BIOS ..

Thanks, @ncmprhnsbl

In my case SATA is already set to AHCI. There is only one SATA device per se, it's a DVD drive. The problem disk is not listed as SATA, but a PCIe. Maybe it does still use SATA bus, I wonder. Anyhow, I'm only seeing AHCI in Bios. I should add that Windows boots on the same machine just fine, from the disk in question.

The linked Dell thread suggests to add
the following kernel argument at boot time:
nvme_load=YES
Could I do it during porteus boot somewhere?

i guess you could try it either on the APPEND line(syslinux/porteus.cfg) or for EFI in the refind.conf on the add_options line..
depending on which you're using..

No, adding nvme_load=YES to APPEND had no apparent effect: it didn't discover any new disks or devices.

The only mention of the word "Samsung" I've seen so far is in the /tmp/psinfo.txt generated with psinfo:

Code: Select all

...
LSPCI OUTPUT:
...
01:00.0 Non-Volatile memory controller [0108]: Samsung Electronics Co Ltd Device [144d:a804]
	Subsystem: Samsung Electronics Co Ltd Device [144d:a801]
Is this giving me a hope? It's a PCI and a NVM, now it only needs to find the SSD disk connected through it :)

...have found in http://www.samsung.com/semiconductor/gl ... aper-0.pdf a mention of a driver, nvme-kmp-default-1.17_3.0.76_0.11-0.x86.64.rpm. Should I try and install it? I thought these things are supposed to be in the kernel?

... have tried to set in BIOS, SATA operation to Disabled -- didn't work, and the disk is not even listed in BIOS anymore. So I'm confused, is a PCIe NVM disk still a SATA disk?

Switched it back to AHCI, and added nvme_load="YES" nvd_load="YES" in porteus.cfg -- no effect

don't know if this helps any: https://wiki.archlinux.org/index.php/So ... rives/NVMe
what kernel version do you have? >3.3 right? anything show in /dev/nvme* ?

Thank you, @ncmprhnsbl , for staying with me on this

Kernel version: 4.9.0-porteus
none of /dev/nvme* or any other promising /dev/* that I could see

It's interesting that BIOS can see this device yet porteus can't. Perhaps there is more to it,it's a new machine from Dell. I'll try to find where to post on their forum.

Hi rych,

nvme driver must be compiled directly into Porteus kernel or loaded from initrd before the search for .sgn file is performed.
This is something for brokenman to look after in next release.

Thanks
Please add [Solved] to your thread title if the solution was found.

The installer of Slackware 14.2 does not support NVMe boot devices (the new type of SSD hard drives with a M.2 PCI-express interface)
https://alien.slackbook.org/blog/build- ... slackware/
I found interesting fix for Slackware-current - look at this post
Probably, this fix may be applicable for Porteus.

For extracting initrd.xz I used this script extract_initramfs.sh

Thanks fanthom and Spasibo Blaze. Your messages give hope that it's doable and might be fixed in Porteus-4.0 by @brokenman? I'll wait. (In the meantime I guess I should make a RAM disk because there is 8GB of RAM. Otherwise writing-reading off my USB drive all the time is too slow)

I've updated the kernel and included the driver. I will upload the latest tomorrow evening.

Thank you, @brokenman, I look forward to trying it. Is it going to appear in http://dl.porteus.org/x86_64/Porteus-v3.2.2/kernel/ or elsewhere - I can't find it?
