KXG60ZNV256G not recognized

[Gerd Pokorra]

Dear Sir or Madam,

in a Laptop is a NVMe SSD from Toshiba with the type name KXG60ZNV256G 
that will not be recognized from Linux. I can load the module nvme but 
there is no /dev/nvme*. I tried it with the kernel version 4.18.16-300. 
The command 'nvme list' show no device.

Could you help or have an idea how to access the device?

Hi Gerd,

Can you please send the output of 'lspci -vvv' for the device in question?

Thanks a lot,

Hello Johannes,

I attached the whole output of 'lspci -vvv' as file lspci.out.

Please check your BIOS if the NVMe is in the AHCI remapped NVMe device mode?

Your dmesg should contain an entry like:
Found %d remapped NVMe devices.

Hello Johannes,

in the BIOS I see 'System Configuration' -> 'SATA Operation'

- Disabled

- AHCI

- RAID On


Currently it is set to 'RAID On'.

Yes the 'RAID On' would be the setting in question, but I have no idea
what consequences turning it off will have. E.g. wrecking an existing
Windows installation and so on.

Hello Johannes,

after setting it to 'Disabled' I see no hard disks of the laptop any 
more with linux and an existing Windows installation is wrecked.

Setting the BIOS to the 'Factory Defaults' bring the Windows 
Installation back. It will be hard to install an Linux on this Laptop.

Yes this is exactly what I expected TBH.

There's not really a lot we can do about without any specs for the AHCI
remapped NVMe thingy.

Lenovo used to have an different BIOS built for Linux on the Yoga series
some years ago if I remember correctly.

I'm not familiar with this product, but if it's like others, the 'AHCI'
'SATA Operation' mode is the one you'd want to select, not 'Disabled'.

Mario,

any idea how to turn off the Intel anti-competitive fake RAID mode
for NVMe for the Dell Presision 7730?

If you go into BIOS setup and choose SATA mode change from 
"RAID ON" to "AHCI".

I know it's an NVME disk, and you're changing SATA mode, but it adjusts
relevant settings on the PCH whether you were using a SATA disk or NVME.

Systems shipped with Linux have it set properly and it should persist
even when BIOS is reset to factory defaults.

Right, "RAID" mode has the PCH compbine multiple devices into one. AHCI
mode doesn't capture other devices behind the SATA controller, so the
NVMe device is visible.

Chris Hellwig,

I am aware there was a patch series submitted at one point for this
technology that was rejected. From your perspective is there (realistically) anything
that Intel can do here for the kernel?  The particular PCH functionality referred above
has been in the industry from Intel silicon for a while now, and is going to continue to
be a barrier to entry for anyone who purchases a machine "with Windows" and tries to
load Linux.

What we really need is Intel stopping to do amazingly stupid things like
this.  Hiding PCIe devices from their drivers is anti-competitive
behavior from a company controlling much of the PC market.

And at the very least we need a way to disable this behavior from the
OS.

My take on this is that the way this thing works and the things it does makes a lot more
sense in the Windows kernel driver model than it does for Linux.  I've heard there are
quantifiable tangible benefits to using this technology on Windows.

Given its been around now for at least 4 generations of Intel silicon (maybe more if
I'm miscounting), I really don't think its going to away from the PC market any time soon.

As such, I don't think that disdaining the technology will get Intel to change it.
So I'm hoping we can constructively come up with something that works in the confines
of its existence to make it a better experience at least.

At least on Dell I could offer a way to accomplish this with SMM today with a small kernel
patch, but it will require a reboot to be effective.

An idea of how it could look:
# cat /sys/platform/devices/dell-laptop/current-sata-mode
ahci [raid] needs-reboot
# echo ahci > /sys/platform/devices/dell-laptop/current-sata-mode
# cat /sys/platform/devices/dell-laptop/current-sata-mode
ahci raid [needs-reboot]
(reboot)
# cat /sys/platform/devices/dell-laptop/current-sata-mode
[ahci] raid needs-reboot

It's not pretty, but maybe it's an improvement?  At least on Dell systems the
distro installers could probe that sysfs node and warn people/fix it across a reboot cycle.

If the relevant Intel PCH registers that are affected were documented, I would think something
similar could be done by kernel PCH initialization code,  but the PCH might need to be reset after
writing them.  That could make the BIOS setting effectively ignored on Linux.
Keith, what do you think on this?

To the best of my knowledge, the hardware mode is working around a
software limitation that doesn't apply to Linux.

That might depend on if said software overcomes those limitations, but I'm
out of the loop to know if that's going to change any time soon, if ever.

I assumed Chritoph's comment was directed toward said software that runs
on the majority of the client PC market, leaving hardware vendors to
think up "creative" work-arounds to its quirks to the detriment of other
software environments. :(

Pre-boot settings like you already have are preferable, right? Otherwise
it's a little more difficult to use the NVMe as your boot drive.

I think the recommended Linux implementation would treat this like a host
bridge and expose the PCI device to the OS without changing any hardware
settings.

But as far as I know, the Intel group that owns this mode has not reached
out to the Linux enabling with hardware specs that we can make public.
The OEMS are probably in a better position to compel this to change than
I am.

The SMM thing I mentioned would basically just be modifying those pre-boot settings
so the next boot it could DTRT for Linux.

It's definitely just a band-aid to the problem.

When the patch series was submitted by Dan the last time (Fall 2016) the
conversation stalled with:

Christoph - are you looking for a whitepaper explaining this beyond the ACHI BAR
remapping documentation that was shared?
http://www.intel.com/content/www/us/en/chipsets/100-series-chipset-datasheet-vol-2.html

I think if we can have start with a list of actionable things needed for another
go at this and an acceptable design architecture before this thing is revisited again
to have a chance at solving it.  Are you amenable to a host bridge?

The thing that lives in the kernel now (aecec8b60422118b52e3347430ba9382e57d6d76)
really does a disservice to people trying to use Linux today:

You mean the PCH registers associated with this stuff?

So it is a one time setting?  If it was permanent it might at least
be useful for a little tool in the installer to offer that choice.
But either way it doesn't help to make the broken intel platforms to
just work.

See the last mail for the functionality that is currently broken and
which needs to work.  Preferably without changes in the NVMe driver
itself, as that is not the place to work around intentionally buggy
platforms.

Yes, we really need to ammend this message to tell people to complain
to Intel and their platform vendor for fucking up things this badly.

Hello,

in the BIOS I set 'System Configuration' -> 'SATA Operation' from

 ? 'RAID On' to 'AHCI'.

After that I installed Windows new. Then I installed Ubuntu 18.04.1 
Sever. The installation works fine. I get the Dual-Boot menu and was 
able to create a partition for Linux on the NVMe SSD. This is what the 
owner of the laptop requested me to do for him.

Thank you for your great support!!!

More correctly it works around a business model limitation that allows
Intel to sell an "integrated" fake raid driver.  Even more importantly
it works around that business model limitation in a completely gross
way, unlike the vmd solution to the same problem in another intel
division, which at least allows to recover from that workaround.

It affects everyone but Intel, that is vendors of non-Intel NVMe SSDs
that have no control on what windows driver is used for their devices,
and it includes any OS that does not have an Intel driver that knows
how to deal with the magic intel AHCI device, which is entirely Intel
private.

Even with the patches from Dan we can't properly use the NVMe device:

 - there is no support for MSI/MSI-X and thus no support for per-queue
   interrupts, thus severly limiting performance
 - there is no support for PCI ID based quirks, which we require
   to support various devices properly
 - there is no way to make SR-IOV work
 - there is no way to make PCI-level FLRs work, or to unbind the
   device in case of a fatal failure

All in all Intel is using their domniance of the CPU and shipset
business to harm various other parties.
