    QuestionQuestion

    Results from lshw show two unclaimed devices. A memory controller and a SMBus. Information on those is scarce, I can’t figure out what they are. Some older posts mentioning them have to do with faulty audio, but I don’t have any issue whatsoever (yet – I’ve installed Ubuntu only 2 days ago).

    id:    memory
    description:    Memory controller
    product:    Sunrise Point-H PMC
    vendor:     Intel Corporation
    physical id:    
    1f.2
    bus info:   
    pci@0000:00:1f.2
    version:    31
    width:  32 bits
    clock:  33MHz (30.3ns)
    configuration:  
    latency =   0
    resources:  
    memory  :   dd12c000-dd12ffff
    
    id: serial
    description:    SMBus
    product:    Sunrise Point-H SMBus
    vendor:     Intel Corporation
    physical id:    
    1f.4
    bus info:   
    pci@0000:00:1f.4
    version:    31
    width:  64 bits
    clock:  33MHz
    configuration:  
    latency =   0
    resources:  
    memory  :   dd132000-dd1320ff
    ioport  :   f040(size=32)
    

    OS: Ubuntu 16.04.3 LTS 64 bits
    Processor: i7-6700HQ
    Laptop model: Dell XPS-15 (9550)
    Additional information: In the Additional Drivers tab from Software & Updates, I have:

    Device unknown

    My question is: Should I care? And if so, how can I resolve these unclaimed devices issues?

    How to interpret lshw’s output

    lshw displays nodes with attributes in a tree-like structure (that can
    be in indented plain text form, HTML, XML or graphically displayed in
    the GUI). Each node has its individual status: it be CLAIMED
    (potentially usable) or UNCLAIMED (no driver has been detected for
    this node), ENABLED (this device is supported and can be used) or
    DISABLED (this device is supported but has been disabled):

    • a node is marked as CLAIMED if a driver (usually a kernel module or a driver within the monolithic kernel) has been loaded for it
    • a node is marked as UNCLAIMED if no specific support for it has been loaded (or lshw has been unable to identify the driver)
    • a node is marked as ENABLED if a driver has been loaded for it and is fully functional
    • a node is marked as DISABLED if the node has been disabled by a configuration, some hardware failure, etc.
    • PMC is a Memory controller. The one in the image is probably related but there is no module you have to use.

    • The SMBus has though. Details from a skylark sunrise system:

      Device: 00:1f.4
      Class:  SMBus
      Vendor: Intel Corporation
      Device: Sunrise Point-H SMBus
      SVendor:        CLEVO/KAPOK Computer
      SDevice:        Sunrise Point-H SMBus
      Rev:    31
      Driver: i801_smbus
      

      See if you have i801_smbus and if you can load the module into the kernel if that fixes this one.

    • See if i801_smbus is blacklisted in /etc/modprobe.d/blacklist.conf

    • If so try to load it and see if that fixes the unclaimed (don’t uncomment the blacklisting before you are sure it works).
