STRUCT IONIC_HWSTAMP_REGS(9)

🦋 struct ionic_hwstamp_regs(9) — the Kernel API Manual page bestie, but make it cute

okay so picture this: you're deep in the Kernel API Manual and you hit struct ionic_hwstamp_regs and you're like "what even is this" — don't worry, I got you 💖 this whole page is literally just one tiny struct holding the hardware's current timestamp registers. two u32s. that's the entire vibe. lowkey iconic for how small it is ✨

---

🌸 NAME 🌸

struct ionic_hwstamp_regs — Hardware current timestamp registers, no cap 🕰️✨

---

💜 SYNOPSIS 💜

struct ionic_hwstamp_regs {
    u32 tick_low;
    u32 tick_high;
 };

that's it. that's the whole struct. she's compact, she's efficient, she's serving minimalism 🎀

🫶 Members 🫶

• tick_low — the low 32 bits of the hardware timestamp. the bottom half, the little spoon, the first half of the story 🍓
• tick_high — the high 32 bits of the hardware timestamp. the top half, the other shoe, the part you gotta glue onto tick_low to get the full number 🌈

ngl bestie, the way these two combine into ONE timestamp is giving main character energy — but the page doesn't tell us how, so I'm not gonna invent it 💅

👑 SEE ALSO 👑

and now, the moment you've all been waiting for… the entire friend group 😭 the page points at the kernel file ./drivers/net/ethernet/pensando/ionic/ionic_if.h, and then it just keeps going. like, going going. grab a snack, bestie 🍓 everyone's invited:

and that's the page!! short struct, long SEE ALSO, absolutely balanced ✨

sign-off time 🎀 this one comes from the source at ./drivers/net/ethernet/pensand... (yes it's literally truncated like that in the footer, bestie, blame the terminal width 😭) and it's dated October 2026. go forth and read your timestamp registers responsibly 🦋💖
