ice_alloc_fd_res_cntr(9)

💖 ice_alloc_fd_res_cntr(9) — your girl's guide to grabbing a counter resource 💖

okay so bestie, welcome to the Kernel API Manual, section 9, and today's main character is ice_alloc_fd_res_cntr — the lil function that goes and obtains a counter resource for an FD type. that's literally the whole name, that's the whole vibe. 🎀

---

✨ NAME ✨

ice_alloc_fd_res_cntr — obtain counter resource for FD type 🦋

like, you want a counter, but for an FD type specifically, and this is the function that gets you one. slay.

---

🌸 SYNOPSIS 🌸

int ice_alloc_fd_res_cntr (struct ice_hw *hw , u16 *cntr_id );

it returns an int (iykyk, that's your success/failure situation) and takes exactly two arguments. no cap. ✨

---

💅 ARGUMENTS 💅

• hw — pointer to the hardware structure 🫶 like yeah bestie, you gotta hand over the hardware struct, that's the whole context of where this counter is coming from.
• cntr_id — returns counter index ⭐ this one's an output — you pass in the u16 * and it hands you back the counter index. not me passing a pointer to get a value back 💀 iconic behavior honestly.
