Is there scheduled a fix for the Intel 660P firmware?

[MLill]

I'm trying to passthrough (kvm/qemu vfio-pci passthrough) an Intel 660P 2TB drive. This fails the sanity check with the following error:

Error starting domain: internal error: qemu unexpectedly closed the monitor: 2019-02-21 10:08:25.261+0000: Domain id=1 is tainted: host-cpu

After reading about the issue here: https://patchwork.kernel.org/patch/10707761/

It seems to me that this could be fixed with a firmware update.

Is this something that is being looked at, at the moment?

Best regards.

Here is the output from the script: https://hastebin.com/asicatirot (also attaced as .txt file, but hastebin is more convenient).

The problem is: QEMU can't initialize the nvme drive for passthrough due to bugged firmware, as per the kernel mail discussion linked. I am wondering if this is getting fixed, so that I can use the disk with PCI-passthrough.

CPU is i9-7960x with 64GB DDR4. Operating system is Fedora 29 with all the latest patches.

Running OS off Samsung 960 Pro nvme, and using pci-passthrough with another Samsung 960 (no problems with Samsungs). As soon as I add the Intel 660p to the VM config, the VM fails to start.

Hi MLill,

Greetings from Intel® SSD Support Group.

Please accept our apologies for our belated reply, we needed to investigate about your inquiry; today, we can share the following details with you:

We have reached our business unit (BU) and according to BU updates, we were not able to replicate the issue that you are seeing. It will be extremely helpful, if you can provide a log for the issue (lspci -vvv).

On the other hand, it seems that a workaround has been applied based on the information available here: https://bugzilla.kernel.org/show_bug.cgi?id=202055 you might want to take a look on this website.

Looking forward to hearing from you.

Have a nice day.
