💅 ice_init_ctrlq(9) — Kernel API Manual vibes only ✨

okay so bestie, welcome to ice_init_ctrlq(9), the main initialization routine for any control Queue. she's the one who sets the whole thing up. the queen bee. the main character of control queue setup 🐝👑

✨ NAME ✨

ice_init_ctrlq — the main initialization routine for any control Queue. like, THE entry point. no cap 💖

🎀 SYNOPSIS 🎀

int ice_init_ctrlq (struct ice_hw *hw , enum ice_ctl_q q_type );

🌸 ARGUMENTS 🌸

  • hw — pointer to the hardware structure. literally handing her the hardware, she'll take it from there 🫶
  • q_type — the specific Control queue type. which flavor of ctrlq are we initializing today, bestie? 🦋

💜 DESCRIPTION 💜

okay so here's the tea, and this part is non-negotiable fr fr: prior to calling this function, the driver *MUST* set the following fields in the cq->structure:

  • cq->num_sq_entries
  • cq->num_rq_entries
  • cq->rq_buf_size
  • cq->sq_buf_size

like, all four. no skipping. if you roll up to this function without those filled in, that's on you, not her 💀 set your fields first, then call. periodt ✨

🔥 NOTE 🔥

heads up bestie: this function does not initialize the controlq locks. nope. not her job. she's leaving that to someone else 🫥 so don't come for her when the locks aren't ready, iykyk
