cxgb4_ptp_gettime(9)
π cxgb4_ptp_gettime β like, the Kernel API Manual page you didn't know you needed
okay bestie, buckle up π this one is from the Kernel API Manual, section 9, and it's genuinely so cute and simple. it's giving "small function, big main character energy." let's go β¨
πΈ NAME πΈ
cxgb4_ptp_gettime β reads the current time from the hardware clock π°οΈ
like yes, that's literally it. it reads the time. from the hardware. slay.
β¨ SYNOPSIS β¨
int cxgb4_ptp_gettime (struct ptp_clock_info *ptp , struct timespec64
*ts );
not me just pasting the signature exactly as-is because we do not mess with code in this house π
π¦ ARGUMENTS π¦
ptpβ the ptp clock structure π«Ά this is the clock boo you're pulling the time fromtsβ the timespec structure that's gonna hold the current time value β° it's the little container the answer gets tucked into
two args, no drama, iconic behaviour honestly.
π DESCRIPTION π
okay so here's the whole vibe: it reads the timecounter, then converts that into a struct timespec, and returns the correct value in ns πβ¨ that's the entire plot. no plot twists. no secret side quests. it reads time, converts it, hands it back to you in ns. periodt.
ngl it's lowkey the most chill function in the whole cxgb4_ptp family β no flags, no defaults, no environment variables, not one single warning. just a clean little time read π₯

tiny note bestie: this page doesn't list any return values beyond the int in the synopsis, so don't go making stuff up about what it returns on failure. we keep it factual in this group chat π

this lil masterpiece lives at ./drivers/net/ethernet/chelsio... (yes it's cutely truncated like that, that's canon), dated October 2026, and it's filed under cxgb4_ptp_gettime(9) in the Kernel API Manual. take care of her, she's iconic ππππ¦πΈ
