STRUCT DC_PROBE_LATENCIES(9)

🌸 NAME 🌸

okay bestie, welcome to the dc_probe_latencies(9) page in the Kernel API Manual — this is struct dc_probe_latencies, and it is literally min/max/avg memory latency in ns. that's the whole vibe: three latency numbers, all hanging out in nanoseconds. ✨

🦋 SYNOPSIS 🦋

       struct dc_probe_latencies {
           uint32_t max_latency_ns;
           uint32_t avg_latency_ns;
           uint32_t min_latency_ns;
        };

🎀 Members 🎀

• max_latency_ns — the maximum latency in nanoseconds. the ceiling, the top number, the "how long did this take" final boss. 😭
• avg_latency_ns — the average latency in nanoseconds. the middle child, doing middle-child things. 🫶
• min_latency_ns — the minimum latency in nanoseconds. the speedy lil bestie, the floor, the "ate and left no crumbs" number. 💅
