ice_is_64b_phy_reg_e82x(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

ice_is_64b_phy_reg_e82x — check if this is a 64bit PHY register. Okay so this is the Kernel API Manual page for that exact function, bestie, and it's lowkey doing one very specific little job.

🎀 SYNOPSIS 🎀

bool ice_is_64b_phy_reg_e82x (u16 low_addr , u16 *high_addr );

🦋 ARGUMENTS 🦋

  • low_addr — the low address to check. This is the address you're asking about, periodt.
  • high_addr — on return, contains the high address of the 64bit register. So it's an output situation, iykyk.

✨ DESCRIPTION ✨

Checks if the provided low address is one of the known 64bit PHY values represented as two 32bit registers. If it is, return the appropriate high register offset to use.

Like, the vibe is: you hand over low_addr, it checks whether that low address is one of the known 64bit PHY values that are represented as two 32bit registers. If yes, it gives you back the appropriate high register offset to use. Simple, iconic, no cap.
