DAXCTL-LIST(1)

✨ NAME ✨

okay so bestie, meet daxctl-list — the DAXCTL-LIST(1) page from the daxctl Manual 🫶. Its whole vibe is: dump the platform Device-DAX regions, devices, and attributes in json. It’s giving “list everything” energy, and honestly? Slay. ✨

🌸 SYNOPSIS 🌸

daxctl list [<options>]

So it walks all the device-dax-regions in the system and lists all device instances along with some of their major attributes. No cap.

You can specify options to limit the output to objects of a certain class, and the classes are regions or devices. By default, daxctl list with no options is equivalent to:

daxctl list --devices

🦋 EXAMPLE 🦋

# daxctl list --regions --devices

{
  "id":1,
  "devices":[
    {
      "chardev":"dax1.0",
      "size":3233808384
    }
  ]
}

look at that little json moment 💖

💅 OPTIONS 💅

• -r, --region= — okay so a device-dax region is a contiguous range of memory that hosts one or more /dev/daxX.Y devices, where X is the region id and Y is the device instance id. The keyword all can be specified to carry out the operation on every region in the system. 🎀
• -d, --dev= — Specify a dax device name, <region id>.<instance id> tuple, or keyword all to filter the listing. For example, to list the first device instance in region1:

# daxctl list --dev=1.0

{
  "chardev":"dax1.0",
  "size":3233808384
}

• -D, --devices — Include device-dax instance info in the listing. This one is the default, bestie. 👑
• -M, --mappings — Include device-dax instance mappings info in the listing. 🗺️
• -R, --regions — Include region info in the listing. 🌈
• -i, --idle — Include idle (not enabled / zero-sized) devices in the listing. 💤
• -u, --human — By default, daxctl list will output machine-friendly raw-integer data. Instead, with this flag, numbers representing storage size will be formatted as human readable strings with units, other fields are converted to hexadecimal strings. Example:

# daxctl list
{
  "chardev":"dax1.0",
  "size":32828817408
}

# daxctl list --human
{
  "chardev":"dax1.0",
  "size":"30.57 GiB (32.83 GB)"
}
