ixgbe_read_sr_area_size(9)

okay bestie, welcome to the Kernel API Manual page for ixgbe_read_sr_area_size(9) 💅✨ no cap, this one is lowkey iconic: it pulls an area size out of a Shadow RAM word and hands it over in bytes. slay.

🎀 NAME 🎀

ixgbe_read_sr_area_size — read an area size from a Shadow RAM word 🦋

✨ SYNOPSIS ✨

int ixgbe_read_sr_area_size (struct ixgbe_hw *hw , u16 offset , u32
       *size );

🌸 ARGUMENTS 🌸

• hw — pointer to the HW structure, aka the main character of this hardware saga 👑
• offset — the word offset of the Shadow RAM to read 🔍
• size — size value read from the Shadow RAM 🎀

💖 DESCRIPTION 💖

So here’s the vibe check: this function reads the given Shadow RAM word and converts it into an area size value specified in bytes ✨. It’s giving “I trust you, bestie” because it assumes the offset you pass in is a valid area size word — so don’t come in here with a random offset and expect magic, okay? 😭

Each area size word is specified in 4KB sector units, and this function reports the size in bytes. That byte-sized result is intended for flat NVM reads 💅 — highkey the whole point, fr fr.

🔥 RETURN 🔥

the exit code of the operation. periodt. 💀

okay that’s the whole page, bestie 🌈. The footer is doing its cute little sign-off with source/version ./drivers/net/ethernet/intel/i... and date October 2026 — and yes, the title ixgbe_read_sr_area_size(9) is right there at the end too 💜✨.
