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.


Thank you,
Federico Reghenzani
