phy_modify_paged_changed(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

phy_modify_paged_changed — bestie, it's the function for modifying a paged register ✨ (yes that's the whole vibe, it does exactly what it says on the tin 🎀)

This one lives in the Kernel API Manual, so like… kernel-level stuff, no cap 👑

🦋 SYNOPSIS 🦋

int phy_modify_paged_changed (struct phy_device *phydev , int page , u32
regnum , u16 mask , u16 set );

Like, that's the whole call signature, copy it exactly or the compiler will simply end you 😭

🌸 ARGUMENTS 🌸

  • phydev — a pointer to a struct phy_device (literally the star of the show, the phy in question 🫶)
  • page — the page for the phy (yep, pages within the phy, she's paged 📄)
  • regnum — register number (which register we're messing with 🔢)
  • mask — bit mask of bits to clear (these bits? cleared. gone. bye 💀)
  • set — bit mask of bits to set (these bits? set. iconic 👑)

✨ DESCRIPTION ✨

okay so here's the tea ☕ — this function returns:

  • a negative errno if something went wrong 😬
  • 0 if there was no change (nothing happened, anticlimactic honestly)
  • 1 in case of change 🔥 (slay, something actually moved)

That's it. That's the whole description. Short king behavior ngl 💜

fr fr if you're checking the return value, 0 and 1 are both "no error" — don't go treating 0 as failure, that's a vibe check you'd fail 🙈

And the whole friend group, in order, no gatekeeping:

That's the whole page bestie, go forth and modify those paged registers 💖✨
