ice_create_all_ctrlq(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ice_create_all_ctrlq — the main initialization routine for all control queues 💖

okay so this is from the Kernel API Manual (section 9, kernel-space girlies know) and it's literally the glow-up routine for every single control queue at once. bestie, let's get into it ✨

🌸 SYNOPSIS 🌸

int ice_create_all_ctrlq (struct ice_hw *hw );

that's it. one function. one shot. one vibe check for the whole control queue situation 🫶

🎀 ARGUMENTS 🎀

  • hw — pointer to the hardware structure. that's your hardware bestie, the whole struct, the main character of this story 👑

✨ DESCRIPTION ✨

okay so listen up because this part is not a suggestion, it's a whole prerequisite era 💅

Prior to calling this function, the driver MUST set the following fields in the cq-> structure for all control queues:

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

yeah. all four. no skipping, no "I'll do it later," none of that 🙈 like I said, MUST — capital letters, italic, bold, the whole dramatic treatment.

So what does this function actually do? It creates all the control queue locks and then calls ice_init_all_ctrlq. cute little two-step. call it once during driver load — once, bestie, we're not doing that thing where you call it in a loop and act surprised 💀

If the driver needs to re-initialize control queues at run time, it should call ice_init_all_ctrlq instead. not this one. this one. is. for. load. time. periodt 🔥
