Hi all, I found this very old topic https://www.spinics.net/lists/linux-rt-users/msg05422.html is there any update on this? I want to disable the APIC timer in order to increase the determinism of my system, but I'm not sure if this is possible without editing the kernel source code. On my machine smp_apic_timer_interrupt takes 2-3 us, I know this is already low, but it's actually the only "frequent" latency that I have on the isolated cpu.
