get_sample(9)

💖 get_sample(9) — Kernel API Manual 💖

okay so bestie, welcome to the kernel API manual moment for get_sample — it's giving low-level sampling realness, and we're gonna read it together. 🫶✨

🌸 NAME 🌸

• get_sample — sample the CPU TSC and look for likely hardware latencies

✨ SYNOPSIS ✨

int get_sample (void );

🎀 ARGUMENTS 🎀

• void — no arguments

💅 DESCRIPTION 💅

okay so here's the vibe: get_sample is used to repeatedly capture the CPU TSC (or similar), looking for potential hardware-induced latency. Literally it's the little sampling gremlin checking for hardware latency chaos. 🧚🔥

bestie, important caveat: it's called with interrupts disabled. no cap, that part is not decorative. ⚠️

🦋 SEE ALSO 🦋

• Kernel file ./kernel/trace/trace_hwlat.c — also peep hwlat_mode_write(9) and init_tracefs(9)

mwah 💋 this cutie is filed under ./kernel/trace, dated October 2026, and it's page get_sample(9) — periodt. ✨👑🎀
