The project uses a real-time kernel, the linux kernel with the PREEMPT_RT patch. So, he needs to have some parameters as:

  • cpufreq.default_governor=performance: Use the performance governor by default (more details here).
  • hugepagesz=1G: Uses 1 giga-bytes for HugeTLB pages (more details here).
  • intel_pstate=disable: Disables the intel_pstate as the default scaling driver for supported processors (more details here).
  • isolcpus=nohz,domain,managed_irq: See the Scheduling and priorization section.
  • no_debug_object: Disables object debugging.
  • nosoftlockup: Disable the soft-lockup detector (more details here).
  • processors.max_cstate=1 and intel_idle.max_cstate=1: Discards of all the idle states deeper than idle state 1, for the acpi_idle and intel_idle drivers, respectively (more details here).
  • cpufreq.default_governor=performance: Use the performance governor by default (more details here).
  • hugepagesz=1G: Uses 1 giga-bytes for HugeTLB pages (more details here)rcu_nocbs: See the Scheduling and priorization section.
  • rcu_nocb_poll: Make the kthreads poll for callbacks.
  • rcutree.kthread_prio=10: Set the SCHED_FIFO priority of the RCU per-CPU kthreads.
  • skew_tick=1: Helps to smooth jitter on systems with latency-sensitive applications running.
  • tsc=reliable: Disables clocksource verification at runtime, as well as the stability checks done at bootup.
