Hi, the diff below adds DT_FA_PROFILE and DT_FA_STATIC defines for arm64 to skip the probe context frames.
Here is how a typical arm64 stack trace looks with and without diff: dt_pcb_ring_get+0x130 dt_prov_profile_enter+0x90 hardclock+0x1b0 agtimer_intr+0xa4 ampintc_irq_handler+0x1c0 arm_cpu_irq+0x34 handle_el1h_irq+0x70 sched_idle+0x294 <-- Diff skips everything above this sched_idle+0x294 proc_trampoline+0x14 ok?
