ice_init_all_ctrlq(9)

💅 NAME 💅

okay so this page is ice_init_all_ctrlq(9) from the Kernel API Manual, and it's lowkey the main initialization routine for all control queues. periodt. 💖

✨ SYNOPSIS ✨

here's the signature bestie, keep it exact:

int ice_init_all_ctrlq (struct ice_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure. that's the whole vibe. 🫶

🌸 DESCRIPTION 🌸

okay so before you call this function, the driver MUST* set these fields in cq->structure for all control queues:

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

like, no cap: these are the prerequisites. set them up first, then come through. ✨

⚠️ NOTE ⚠️

heads up bestie: this function does not initialize the controlq locks. not me expecting it to, because it won't. 💀
