💖 ice_read_sr_word(9) 💖

okay so bestie, welcome to the Kernel API Manual page for ice_read_sr_word(9) — yes, the (9) is the kernel-section moment, and this whole page is about reading a Shadow RAM word. let’s get into it ✨

---

✨ NAME ✨

ice_read_sr_word — Reads Shadow RAM word 🫶

🌸 SYNOPSIS 🌸

int ice_read_sr_word (struct ice_hw *hw , u16 offset , u16 *data );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. iconic hardware pointer behavior
• offset — offset of the Shadow RAM word to read (0x000000 - 0x001FFF). that’s the range, bestie
• data — word read from the Shadow RAM. the word ends up here

🦋 DESCRIPTION 🦋

okay so this Reads one 16 bit word from the Shadow RAM using ice_read_flat_nvm. that’s the whole assignment. 💅

the NVM lock is acquired and released internally by ice_read_flat_nvm around the FW read, so this function must be called without the lock held. do not show up with your own lock, bestie 😭

🚨 important: call this function without the lock held — the NVM lock is acquired and released internally by ice_read_flat_nvm around the FW read. no cap.

⭐ RETURN ⭐

zero on success, or a negative error code on failure. that’s the return situation, periodt. 💖
