  • [gentoo-user] I915 mobile firmware

    From Peter Humphrey@21:1/5 to All on Tue Nov 15 18:10:01 2022
    Hello list,

    My new laptop shows this from /proc/cpuinfo:

    8
    processor : 0
    vendor_id : GenuineIntel
    cpu family : 6
    model : 154
    model name : 12th Gen Intel(R) Core(TM) i7-12700H
    stepping : 3
    microcode : 0x421
    8

    I've been hunting around to find which modules I need to load from sys-kernel/ linux-firmware, and it isn't at all clear.

    Some sources say that the processor is a mobile complement to Alder Lake 11th gen, but I also see it as just Tiger Lake. The web seems full of helpful information, but not quite helpful enough for me. :-(

    Regards,
    Peter.

    Install lshw - might give more info.

    Boot off of an install, ubuntu, sysrescue or other live USB and
    investigate dmesg.

    And lsusb, lspci,..(I think they're both readily available)

    I've been hunting around to find which modules I need to load from sys-kernel/ linux-firmware, and it isn't at all clear.

    Some sources say that the processor is a mobile complement to Alder Lake
    11th gen, but I also see it as just Tiger Lake. The web seems full of
    helpful information, but not quite helpful enough for me. :-(

    Intel's website mentions this 12th Gen CPU was *formerly* known as Alder Lake, was released in Q1 2022, but does not make it clear what it is now named as:

    https://www.intel.co.uk/content/www/uk/en/products/sku/132228/intel-core-i712700h-processor-24m-cache-up-to-4-70-ghz/specifications.html

    So, I'd be inclined to take their word for it. This Wikipedia lists the processor as a mobile Alder Lake:

    https://en.wikipedia.org/wiki/Alder_Lake#Alder_Lake-H

    The Tiger Lake processors are 11th Gen and their model numbering start with 11***.

    This page also confirms your family and model number as per cpuinfo use the Golden Cove (P-cores) microarchitecture:

    https://en.wikichip.org/wiki/intel/microarchitectures/alder_lake#CPUID

    sys-apps/dmidecode will provide additional information to determine the specifics of what the MoBo firmware reports.

    Lee 😎

    lsusb won't offer much info on a CPU ...

    lscpu should be more appropriate.
