💖 pvr_kccb_send_cmd_powered 💖

okay bestie, welcome to the Kernel API Manual entry for pvr_kccb_send_cmd_powered — yes that's a mouthful, yes we're gonna get through it together, and yes it's lowkey iconic 🎀

✨ NAME ✨

pvr_kccb_send_cmd_powered — send a command to the KCCB, with a PM ref held. that's the whole vibe. you're sending a command and you're keeping a power-management reference alive while you do it 🫶

🌸 SYNOPSIS 🌸

int pvr_kccb_send_cmd_powered (struct pvr_device *pvr_dev , struct
       rogue_fwif_kccb_cmd *cmd , u32 *kccb_slot );

literally just three args, she's not complicated 💅

🦋 ARGUMENTS 🦋

  • pvr_dev — the device pointer. like, the device. your main character 🎀
  • cmd — the command you wanna send. the message. the moment. ✨
  • kccb_slot — address where the KCCB slot for this command gets stashed. and guess what? she may be NULL. no slot storage, no problem 💀

⭐ RETURN ⭐

here's the vibe check on what you get back:

  • Zero on success 🎉 (slay, it worked)
  • -EBUSY if there's a timeout while waiting for a free KCCB slot 😭 (no slot for you, bestie — the queue said "not right now")

ngl bestie, if you're gonna call this one, remember the PM ref is held for you — that's the whole point of the _powered suffix. don't leave her hanging 🙈
