💅 be_cmd_crea...lt_pdu_queue — Kernel API Manual, section (9) 🎀

okay so bestie, welcome to the group chat where we talk about kernel API pages, and honestly? this one is a whole vibe. it's section 9 of the Kernel API Manual, and the full function name got a little bit truncated in the header (the way manpages do 😭) so let's just say it out loud properly, mkay? 🦋

✨ NAME ✨

be_cmd_create_default_pdu_queue — literally just creating a DEFQ for the adapter. that's it. that's the whole job. 💅

🌸 SYNOPSIS 🌸

int be_cmd_create_default_pdu_queue (struct be_ctrl_info *ctrl , struct
be_queue_info *cq , struct be_queue_info *dq , int length , int
entry_size , uint8_t is_header , uint8_t ulp_num );

🎀 ARGUMENTS 🎀

  • ctrl — a ptr to ctrl_info. yep, just a pointer. iconic.
  • cq — the Completion Queue, bestie. it completes things. 💖
  • dq — the Default Queue. the main character of this whole function ngl.
  • length — the ring size. how big the ring is. no cap.
  • entry_size — the size of each entry in the DEFQ. every entry gets its lil moment. ✨
  • is_header — Header or Data DEFQ. you gotta tell it which one, it's not a mind reader 🙈
  • ulp_num — Bind to which ULP. gotta pick your fave ULP fr fr.

🦋 DESCRIPTION 🦋

so what does this actually do? it creates an HDR/Data DEFQ for the ULP you passed in. that's the whole assignment. 🫶

and then the FW (firmware, iykyk) posts the Unsol PDU</>s on this queue. lowkey obsessed with how that works.

return values, bestie, pay attention: Success: 0, Failure: Non-Zero Value. so if you get 0 you ate and left no crumbs. anything else? something went wrong 💀
