STRUCT IDPF_PTP_DEV_TIMERS(9)

✨ struct idpf_ptp_dev_timers — system time & device time values 💖

okay so bestie, quick vibe check: this is a page from the Kernel API Manual, and it's all about a little struct called idpf_ptp_dev_timers 🕐✨ She's not complicated, she's not doing too much — she just holds two timestamps so the driver can talk about "when" in two different clocks at once. iconic behaviour honestly.

🌸 SYNOPSIS 🌸

struct idpf_ptp_dev_timers {
    u64 sys_time_ns;
    u64 dev_clk_time_ns;
 };

like... that's the whole thing. two u64 fields and a dream 💅

🎀 Members 🎀

• sys_time_ns — the system time value, expressed in nanoseconds ⏱️ that's your host's idea of now.
• dev_clk_time_ns — the device clock time value, also expressed in nanoseconds 🦋 that's the NIC's idea of now. and yes, they get to disagree, that's literally the whole point of keeping both.

ngl the _ns suffix is doing so much heavy lifting here — nanoseconds, bestie, not nanosleep 😭

mwah 💋 sending you off with the deets: this one lives in ./drivers/net/ethernet/intel/idpf, the date on it is October 2026, and the man page source tag is struct idpf_ptp_dev_timers(9). slay, go timestamp something 🌈⭐🫶
