    Thank you all,

    I have pulled the newest `linux-next` changes and compiled it, my laptop
    boots well now! https://linux-hardware.org/?probe=271fabb7a4 , but it
    still prints some `WARNING` information at startup: https://linux-hardware.org/?probe=271fabb7a4&log=dmesg . May this output
    is useful for you maintainers.

    And, thank you all again.

    Hi Larry Wei, hi Ben,

    For context this is about https://bugs.debian.org/1103397, and which
    Ben did forward in https://lore.kernel.org/regressions/[email protected]/T/

    Going thorough the bugs I notice there was a related upstream
    discussion/patch relating to ae6012d72fa6 ("x86/pkeys: Ensure updated
    PKRU value is XRSTOR'd") in the following:

    https://lore.kernel.org/all/[email protected]/

    There were some followups, but discussion ended on 18.01.2025.

    Did this felt through the cracks?

    Regards,
    Salvatore

    Salvatore Bonaccorso,

    Yes, let's just consider it as good. But in fact, there are still many problems, such as the one mentioned above ( linux-hardware.org/?probe=271fabb7a4&log=dmesg ), and almost all laptops
    using Zhaoxin CPUs cannot adjust the backlight brightness, which is
    **VERY HARMFUL** to the eyes!

    Dear TonyWWang-oc,

    Yes, but actually, these graphics cards are your products, and neither
    C-960 nor C-1080 seem to be open source.The drivers provided on your
    official website do not seem to be used for Debian.I downloaded your
    drivers and extracted them, and I found that each file has the license content.Can I assume that these drivers are open source?

    Dear Larry,

    The graphics driver package contains both kernel-mode and user-mode
    components, where the kernel-mode components are open source, while
    graphics rendering tasks predominantly rely on user-mode implementations.

    BRs!

    Dear Larry,

    We are currently investigating the causes of the WARNING messages you mentioned in this log:
    [ 4.141284] ------------[ cut here ]------------
    [ 4.141285] alg: self-tests for sha1 using sha1-padlock-nano failed (rc=-22)
    [ 4.141302] WARNING: CPU: 2 PID: 657 at crypto/testmgr.c:5865 alg_test.cold+0xb7/0xe0

    Regarding the inability to adjust the laptop backlight brightness, we
    believe this issue is unlikely related to the CPU itself. It is
    recommended to contact the laptop manufacturer to confirm whether the
    device supports backlight brightness adjustment and inquire about
    specific configuration methods, such as installing specific EC
    controller drivers or updating graphics card drivers.

    BRs!
    TonyWWang-oc

    Looking at what has changed in linux-next, this appears to be the fix:

    commit d1e420772cd1eb0afe5858619c73ce36f3e781a1
    Author: Chang S. Bae <[email protected]>
    Date: Tue Apr 15 19:16:58 2025 -0700

    x86/pkeys: Simplify PKRU update in signal frame

    This is currently in the tip tree but won't go to Linus until after the
    6.15 release.

    As this fixes a regression on real CPUs, it should not need to wait for
    the next release cycle, right?


    Ben.

    Hi! Ben,

    It will be OK! I don't think there are many people using this type of
    machine, after all, they can't even adjust the backlight, and I don't
    think anyone likes to use this type of machine, and they also like to
    use it to install Debian. I am very happy that this issue can be fixed.
    For now, I just need to use the kernel I compiled myself.
    Thank you all.

    P.S. And I suspect that this change has been affecting all non-Intel and non-AMD machines for a long time, as there is no "non-free-firmware"
    suitable for them.

    Ben,

    I remember two years ago, it seemed like the backlight of this laptop
    could be adjusted. At that time, I installed Ubuntu on this laptop and
    there seemed to be a directory called "acpi_video" in the "/sys/class/backlight/" directory. However, at some point, this
    directory no longer existed. At that time, I was not very familiar with
    Linux distributions and didn't know how to report bugs.

    Regards,
