💖 pvr_stream_process(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for pvr_stream_process — yes that's the manual name, we're not copy-pasting the header line, we're folding it in like a cute little intro. slay.

✨ NAME ✨

pvr_stream_process — literally builds an FW structure from a stream. that's the whole vibe. 🦋

---

🧚 SYNOPSIS 🧚

int pvr_stream_process (struct pvr_device *pvr_dev , const struct
       pvr_stream_cmd_defs *cmd_defs , void *stream , u32 stream_size , void
       *dest_out );

like, that's the signature, no cap. don't touch it, it's iconic exactly as-is. 👑

🌸 ARGUMENTS 🌸

• pvr_dev — the device pointer. your fave device, pointing right at you. 🫶
• cmd_defs — the stream definition. it's giving "the blueprint". 🎀
• stream — pointer to the command stream. the actual stream bestie. 💅
• stream_size — size of the command stream, in bytes. units matter, periodt.
• dest_out — pointer to the destination buffer. where the output goes to live its best life. ✨

💜 DESCRIPTION 💜

so here's the tea: the caller is responsible for freeing the output structure. that's you. you're the caller. no take-backs, no "not me", you free it. 🙈

• -ENOMEM on out of memory — the vibes ran out of RAM, it happens. 💀
• -EINVAL on malformed stream — the stream is not passing the vibe check. 😭
