efa_com_cmd_exec(9)

📦 version 7.3.1, in nixpkgs unstable

💖 efa_com_cmd_exec (section 9) — the Kernel API Manual era 💖

okay so bestie, welcome to the efa_com_cmd_exec page, straight out of the Kernel API Manual 🎀 this one's giving "small function, big responsibilities" and honestly? iconic.

✨ NAME ✨

efa_com_cmd_exec — Execute admin command 👑

🌸 SYNOPSIS 🌸

int efa_com_cmd_exec (struct efa_com_admin_queue *aq , u8 opcode , u8
flags , void *payload , size_t payload_size , struct efa_admin_acq_entry
*comp , size_t comp_size );

like, that's the whole vibe right there 💅

🦋 ARGUMENTS 🦋

  • aq — the admin queue, bestie. that's her whole thing 💖
  • opcode — the opcode of the admin command. the "what are we even doing" of it all ✨
  • flags — the admin command header flags. little header accessories, we love to see it 🎀
  • payload — the payload of the admin command. the actual cargo 🚚
  • payload_size — how big that payload is, size-wise. no guessing 🧚
  • comp — the command completion return entry. this is where the tea gets delivered ☕
  • comp_size — the size of the command completion. okay so this one comes with lore: Submit an admin command and then wait until the device will return a completion. The completion will be copied into comp. like it literally submits, waits for the device, then copies the completion into comp. main character behaviour, no cap 🫶

💜 DESCRIPTION 💜

so what does it return? return - 0 on success, negative value on failure. that's it, that's the whole description, and honestly it ate 🔥

ngl bestie, negative value means things went sideways. keep an eye on that 🙈

⭐ SEE ALSO ⭐

like, go read the whole friend group, iykyk 💅✨

okay that's the page bestie, hope it slayed 🫶 and for the cute sign-off: this whole thing lives in ./drivers/infiniband/hw/efa, dated October 2026, and yes it's still efa_com_cmd_exec(9) at the bottom because we keep the brand consistent 💖🎀🌸
