i40e_read_nvm_word_srctl(9)

💅 i40e_read_nvm_word_srctl 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil function from the i40e driver fam and it's literally just here to read a single 16-bit word out of Shadow RAM. tiny job, big main character energy 🎀

---

✨ NAME ✨

i40e_read_nvm_word_srctl — reads Shadow RAM via the SRCTL register 🦋

---

🌸 SYNOPSIS 🌸

int i40e_read_nvm_word_srctl (struct i40e_hw *hw , u16 offset , u16
*data );

no cap, that's the whole signature. three args, one int coming back at you 💖

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. it's giving "here's the hardware context, pls use it wisely" 👑
• offset — offset of the Shadow RAM word to read, and the valid range is 0x000000 – 0x001FFF (yes, keep it in there, don't go wandering 🫶)
• data — the word read from the Shadow RAM. this is where the answer lands, bestie 💫

---

🔥 DESCRIPTION 🔥

Reads one 16 bit word from the Shadow RAM using the GLNVM_SRCTL register. that's it, that's the vibe — one word, one register, zero drama 🧚
