pvr_ccb_init(9)

💅 pvr_ccb_init(9) — Initialise a CCB 💅

Okay so welcome to the Kernel API Manual, bestie — this is the page for pvr_ccb_init(9), and it is literally about initialising a CCB. Slay. Let's get into it. 🫶

---

✨ NAME ✨

pvr_ccb_init — Initialise a CCB

---

🌸 SYNOPSIS 🌸

The signature is giving main-character kernel energy:

int pvr_ccb_init (struct pvr_device *pvr_dev , struct pvr_ccb *pvr_ccb ,
       u32 num_cmds_log2 , size_t cmd_size );

---

🎀 ARGUMENTS 🎀

• pvr_dev — Device pointer. That's the device pointer, periodt.
• pvr_ccb — Pointer to CCB structure to initialise. The one you're setting up, bestie.
• num_cmds_log2 — Log2 of number of commands in this CCB. Yes, log2 — the exponent version.
• cmd_size — Command size for this CCB. Literally the command size for this CCB.

---

💖 RETURN 💖

Here's the return vibe check:

• Zero on success, or
• Any error code returned by pvr_fw_object_create_and_map.

Zero means you ate. Otherwise it's that error code from pvr_fw_object_create_and_map, no cap. 😭
