igc_phy_hw_reset(9)

💖 NAME 💖

okay bestie, meet igc_phy_hw_reset(9) — it’s the Kernel API Manual entry for a PHY hardware reset, and it’s lowkey doing important reset choreography 🫶

✨ SYNOPSIS ✨

s32 igc_phy_hw_reset (struct igc_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. That’s the whole arg list, bestie: one pointer, main character energy.

🌸 DESCRIPTION 🌸

okay so here’s the vibe: first, verify the reset block is not blocking us from resetting. Then acquire the semaphore (if necessary), and read/set/write the device control reset bit in the PHY. Wait the appropriate delay time for the device to reset, and release the semaphore (if necessary). That’s the routine — check, semaphore if needed, reset bit read/set/write, delay, release semaphore if needed. slay ✨
