  • Ticket #16504 – Description

    initial v15  
    22installed Haiku R1/beta2 on my mini pc along with Windows and Linux. Haiku runs fine except a tiny boot glitch (https://discuss.haiku-os.org/t/r1-beta2-uefi-boot-issue/9915/7) and no audio.

    4 The bug report is about a different issue: the **cpu clock stucks at a single frequency**. Not only programs run slower than on Windows/Linux, also the cpu gets hot and the fan spins most of the time. The cpu seems switching never to 600/800 mhz when idle. (https://discuss.haiku-os.org/t/why-do-chess-engines-run-slow-on-haiku/9929/14)

     12Because of the missing cpufreq module, Haiku can't change neither to lower clocks (down to 800mhz) when idle, nor higher (up to 2.3ghz) under load. \\

     14The cpu J3455 runs the whole time at it's default frequency of 1.5ghz. Windows and Linux don't have this problem on the same real hardware.
