✨ vsp1_isp_job_run(9) ✨

okay so this is a page straight out of the Kernel API Manual, and it's literally about making a buffer transfer job actually go 🏃‍♀️💨 buckle up bestie

🌸 NAME 🌸

vsp1_isp_job_run — Run a buffer transfer job 🎬

🦋 SYNOPSIS 🦋

int vsp1_isp_job_run (struct device *dev , struct vsp1_isp_job_desc *job
);

🎀 ARGUMENTS 🎀

  • dev — The VSP1 struct device, aka the hardware babe we're talking to 💻
  • job — The job to be run, like the actual thing you're yeeting at it 📨

💖 DESCRIPTION 💖

So here's the vibe: this function runs the display list that's chillin' inside the job description your caller handed over. ✨

lowkey important: the job must have been prepared with a call to vsp1_isp_job_prepare, and the job's display list shall be valid. no cutting corners bestie 🙈

Jobs can only be run on VSPX instances that have been started — like, the party has to actually be happening first 🎉

If you try to run a job after the VSPX has been stopped, you get -EINVAL back, and the caller is responsible for releasing the job resources with vsp1_isp_job_release. no take-backs, that's on you 💅

But when a job does run successfully? chef's kiss 👑 all the resources acquired by vsp1_isp_job_prepare get released by this function, and the caller doesn't have to do a single extra thing. literally no further action required. main character energy fr fr 🫶

⭐ RETURN ⭐

0 on success, or a negative error code on failure 😭 (we love a binary-ish outcome ngl)
