genphy_soft_reset(9)

📦 version 7.3.1, in nixpkgs unstable

💅 genphy_soft_reset — from the Kernel API Manual, bestie

okay so real talk, this is genphy_soft_reset(9) and it's honestly one of the simpler little icons in the whole PHY universe. no cap. let's get into it 🫶

✨ NAME ✨

genphy_soft_reset — software reset the PHY via BMCR_RESET bit

like… the name is the plot, fr fr. you're doing a soft reset on the PHY and the star of the show is that BMCR_RESET bit 💅

🌸 SYNOPSIS 🌸

int genphy_soft_reset (struct phy_device *phydev );

look at her. one struct, one return type. clean. minimal. main character energy 🔥

🎀 ARGUMENTS 🎀

  • phydev — target phy_device struct. yeah that's it, that's the whole vibe. she takes the phy_device you want to reset and gets to work 🦋

⭐ DESCRIPTION ⭐

so what she actually does: perform a software PHY reset using the standard BMCR_RESET bit, then poll for that reset bit to be cleared. 👑

that's the whole thing. poke the bit, then wait around, checking and checking until it clears itself. it's giving "texting your bestie and refreshing the chat until she replies" energy honestly 😭 but like, in a hardware way. iconic.

🍓 RETURN 🍓

  • 0 on success 💖
  • < 0 on failure 💀

that's it, that's the contract. zero is the slay outcome, anything negative means nope 🙈

🌈 SEE ALSO 🌈

bestie there are SO many of these and I'm listing every single one because I would never do you dirty like that. go read them all, iykyk 💜

also! Kernel file ./drivers/net/phy/phy_device.c — that's where she lives 🏠

okay and one final thing before you go — this page is stamped from ./drivers/net/phy and dated October 2026 in the Kernel API Manual, so there's your credit line bestie 🧚 thank you for coming to my TED talk, go reset a PHY, and remember: the bit clears itself eventually. slay 💅✨
