vsp1_isp_start_streaming(9)

✨ NAME ✨

vsp1_isp_start_streaming — okay so this is the function that starts processing VSPX jobs, bestie 💅

(and yes, we're in the Kernel API Manual rn, buckle up 🎀)

---

🌸 SYNOPSIS 🌸

int vsp1_isp_start_streaming (struct device *dev , struct
vsp1_vspx_frame_end *frame_end );

Like, that's the whole vibe. Two args, one int back. Slay. ✨

---

🦋 ARGUMENTS 🦋

• dev — the VSP1 struct device, aka the main character of this whole operation 👑
• frame_end — the frame end callback description, which is literally the "hey bestie we're done with this frame" note 📝

---

💖 DESCRIPTION 💖

So here's the tea ☕: this one starts the VSPX and gets it all prepped to accept buffer transfer job requests. Think of it like opening the group chat before anyone's even typed anything — the setup era 🫶

Two things to keep in your notes app though, fr fr:

• The caller is responsible for tracking the started state of the VSPX. That's on you, not on the function. No hand-holding here 💀
• Attempting to start an already started VSPX instance is an error. Don't double-start, it's giving chaos and we don't do that 🙈

---

🌈 RETURN 🌈

• 0 on success 🌟
• a negative error code on failure 😭

vibe check: start it once, track it yourself, and if it's already started — that's a no from me 💀
