List features of NVMe drive (like hdparm -I for non-NVME)

With a non-NVMe drive, I can run: # hdparm -I /dev/whatever | grep TRIM Data Set Management TRIM supported (limit 8 block) Deterministic read data after TRIM With a Samsung 960 EVO 1TB NVMe drive (PCI Express), I get: # hdparm -I /dev/nvme0n1 /dev/nvme0n1: HDIO_DRIVE_CMD(identify) failed: Inappropriate ioctl for device I can run # smartctl --all /dev/nvme0n1 And get some information about the drive, but nothing about TRIM type. I installed nvme-cli, and ran nvme get-feature -f 0 to -f 0xe and got some features from the drive, but nothing about TRIM type. Is there a way in Linux to query an NVME device, to list what type of TRIM it supports? Is there a way in Linux to query an NVMe device, to get a list of anything else hdparm -I would show if it weren't an NVMe, that smartctl and nvme don't seem to cover?
