AMD users should immediately switch to the latest Linux 5.11 kernel

The latest release of the Linux kernel features some impressive performance enhancements for AMD hardware.

Released over the valentine’s day weekend, Linux kernel 5.11 fixed a major performance regression that impacted the AMD Zen architecture. Thanks to the fix, Zen-based processors such as Ryzen and EPYC have been benchmarked as being faster out of the box than on previous kernels. Also debuting in the release is support for AMD “Van Gogh” and “Dimgrey Cavefish” GPUs.

Anybody with a before/after benchmark? I will see if I can make one :smiley:

    nice, when Intel users are asked to update their shit its only to decrease the performance...

  • I half expected a new exploit or what not.. but it's performance boost

  • @caracal oh hi floppa <3

    no thats nvidia users lol

  • Reading the title I expected a vulnerability. Instead, it's about a performance boost. Awesome news.

  • I can't believe it , before the upgrade my Ryzen 9 3900 max GHZ was alwayse stuck at 3.9 GHZ , now after the upgrade it can even reach 5.6 GHZ !

    Is that a joke or what ?

    any steps how to update ?

    apt dist-upgrade
    shows no update and is in older version yet.

  • Well upgrading broke lxd and zfs for me so i have to pass this :(

  • Sounds... intriguing. Waiting for some benchmarks first :P

    Likely the kernel you're installing doesn't include the ZFS module while your distro-built one has it added in.

    You'll need to install your distributions equivalent of a zfs-dkms package to get the module running. It may need to be a newer version of zfs-dkms to support a kernel that high though, I remember there being a PPA for Ubuntu but don't have the link to hand and not sure if other distributions have similar

    @saibal said: Did Physics go on a vacation?

    yes

    i'll try longer compile, but if it needs to scale up to 5ghz for a bit and back down in a minute it does not seem like it uses much more, and it scales back down very aggressively when not needed

    I understand. I've just uploaded an image for you guys to get an idea what Ryzens are capable of :)

    @marvel

    Interesting news (for some) - but please do not word the title in a way that makes many think there is a vulnerability that needs immediate attention when in fact it's just about some performance boost.

    As for the boost, thanks no, I won't play the funny linux lottery. I'm shocked sometimes when I see how linux bazaar development works out and how unreliable its result is. Unless one has a rather basic system upgrading ones distro or kernel risks to basically but a lottery.

    Could you compare geekbench 5?

    That would interest me as well. Is it worth it to risk a rock-solid battle hardned 4.19 kernel for those juicy extra % if the host remains on ancient tech?

    Once nodes are done it's either that, "moar cores" or graphite which seems to have died off lately.

    (As a side note and as a personal opinion - no ARM is not the future. Intel once thought x86 is the next best thing after sliced bread but come AMD...people really think they will just sit on their asses and wait for ARM to take over? hah.)

    That is why you should ignore "immediately switch" instructions that are for a performance benefit. Let other people gamma test it first...

    Different for updates purely for actively exploited or easily exploitable (so will be actively exploited in no time at all) security issues though.

    no way my pc can be that fast...

  • Waiting for reports of CPUs bursting in flames. :)

  • I'm surprised more people aren't running Clear Linux OS. Especially, since they optimize for Intel which helps all those old machines run better, but the optimization they do often help AMD big core stuff as well.

    It is somewhat surprising to see people surprised you need current software to work with current hardware.
