    Thanks a lot. Running this with Kwin-LowLatency on Gentoo and it feels great.

    FYI -
    Each of the tests is specifically designed to trigger a code path in the Linux kernel. Unlike most other benchmarks/performance tests, their purpose is not to simulate a real-life workload. github.com/mfleming/adrestia

    Has the AMD/schedutil issue been fixed?

    Any chance to get the tunables:
    /proc/sys/kernel/hrtimer_granularity_us
    /proc/sys/kernel/hrtimeout_min_us
    back?

    They were excellent for fine-tuning.

      They're still there. I'm guessing you just applied muqss? They're part of the -ck patchset.

      I switched "back" to -ck now.
      Amazing!

    Stable on 5.1.15. The new BMQ scheduler shows quicker perf benchmarks but the ck patchset is much more ideal for desktop usage. Thanks!

    Anyone else seeing boot time RCU stalls with 5.1.15-ck1? Seems to happen about once every four boots.

      By the way there's no stack trace for the stalls.

      In the end this was fixed by adding "nothreadirqs" to the kernel command line.

      P.S. Thanks for the great work CK :)

      Thanks. That's why I made threaded IRQs not a default configuration since it's not guaranteed to work everywhere.

    ck1: KSysguard shows 2 cores at 100% when idle, htop shows 2-3% average on all 4 cores but load average of 5.5.
    Is this expected behaviour?

      Nothing said. Tracked it down to a SSD failure.

    When compiling kernel, load goes up to 12 on AMD Ryzen 5 2500U and opening new apps is extremely slow
