      如题,在一般的ubuntu内核中,可以选择fully preemptible kernel(Real-Time)模式以是的某些程序能够最高效运行ccd78a10-fbac-4e6c-9ca4-9e4146d9eb24-9c319a5bf7ac3cf37f537295c568d80.jpg
      但是在官方提供的额kernel 5.10.110中,没有该模式的选择5fb719b1-35b0-4383-8c34-52ce824268e5-5d853ef0a097980a94cec21d97e9471.jpg

          去年同样操作过,没问题,今年买了两台新的CM5,发现运行软件一直警告,无法解决
          详细对比了去年和今年版本的差异,发现去年系统版本是

          Linux coolpi 5.10.110 #2 SMP Sun Dec 22 10:43:41 CST 2023 aarch64 aarch64 aarch64 GNu/Linux
          

          而新机器的版本是

          Linux coolpi 5.10.110 #2 SMP Sun Dec 22 10:43:41 CST 2024 aarch64 aarch64 aarch64 GNu/Linux
          

          有新老版本的差异,在尝试各种方式安装kernel无果,尝试备份老机器后,还原到新机器中也无法开机后,重刷了2023版本的系统,重装系统后运行正常。
          最后,需要请教一下,新老版本在preemption model上有无差别?
