ice_update_recipe_lkup_idx(9)

💅 ice_update_recipe_lkup_idx — the kernel API manual, bestie edition ✨

okay so this page lives in the Kernel API Manual, and the star of the show is ice_update_recipe_lkup_idx(9). buckle up, we're updating a default recipe based on the lkup_idx 🎀

✨ NAME ✨

ice_update_recipe_lkup_idx — update a default recipe based on the lkup_idx 💖

---

🌸 SYNOPSIS 🌸

int ice_update_recipe_lkup_idx (struct ice_hw *hw , struct
       ice_update_recipe_lkup_idx_params *params );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW struct, literally the hardware vibes you're handing over 💫
• params — the parameters used to update the default recipe, iykyk 🫶

---

💜 DESCRIPTION 💜

okay so here's the tea: this function only supports updating default recipes. and it only supports updating a single recipe based on the lkup_idx, one at a time. no multitasking, no overachieving, one at a time periodt 💅

the way it works is a read-modify-write operation, and honestly? iconic. here's the sequence:

1. first, get the current recipe contents based on the recipe's ID 🔍
2. then modify the field vector index and mask if it's valid at the lkup_idx ✅
3. finally, use the add recipe AQ to update the pre-existing recipe with the modifications 🔥

that's it, that's the whole flow. ate and left no crumbs 👑

💀 reminder bestie: default recipes only, one lkup_idx per call. don't come for me if you try to be ambitious 🙈
