STRUCT HWTSTAMP_PROVIDER(9)

💖 struct hwtstamp_provider — the hwtstamp provider object 💖

okay so bestie, welcome to the struct hwtstamp_provider(9) page — this is from the Kernel API Manual, and it's literally the little object that represents a hwtstamp provider. it's giving "small struct, big job" energy ngl 🎀

✨ SYNOPSIS ✨

here's the whole thing laid out, exactly as it lives in the kernel:

struct hwtstamp_provider {
    struct rcu_head rcu_head;
    enum hwtstamp_source source;
    struct phy_device *phydev;
    struct hwtstamp_provider_desc desc;
 };

look at her. four members. no notes. 🫶

🌸 Members 🌸

• rcu_head — the RCU callback that gets used to free the struct. yes, she has a whole lifecycle, we love a self-cleaning queen 💅
• source — the source of the hwtstamp provider (it's an enum hwtstamp_source, so iconic of her).
• phydev — a pointer to the phydev source, and it's specifically for when a PTP is coming from phylib. so if that's your situation? this is your girl 🔥
• desc — the hwtstamp provider description. it's a struct hwtstamp_provider_desc and it does exactly what it says on the tin, no cap.

🦋 SEE ALSO 🦋

• Kernel file ./include/linux/net_tstamp.h — go read it, iykyk
• struct hwtstamp_provider_desc(9)
• struct kernel_hwtstamp_config(9)

those two structs are her besties fr fr, go say hi 💜
