Linux support for M.2 / NVMe devices on RAID configured controllers?

Getting more and more reports of Linux not seeing M.2 and NVMe devices. Always caused by it being on a controller configured in RAID mode instead of AHCI. Dell, Lenovo, others now. Latest checked was 4.8.14 and still doesn't work.

Does anyone know if 4.9 will address this serious issue that is growing? What exactly is the issue, is it just some table needs to be updated? I find a lot of linux not working on hardware only doesn't work because the device id isn't added to some table, why have a table when you know the type of device it is, the generics work fine, windows always works with them for this reason, any special features items may need to be in a table but not generic devices.

Thank for any Info.

You'd have to show some example and maybe we could look at it.

As with all devices they tend to be only tested with windows at the factory. As to why others are having issues I can't say. Guesses include goofy uefi, lack of support for controller, possible pal issues, possible timing issues or bios reading of devices or other problems.

Any new update on linux support nvme raid0

hi, I also want to know if currently linux could support nvme raid 0 with intel raid controller configured in bios.
I have a p50 with dual nvme disk, and currently i can only use mdadm to create software raid 0 on nvme.
