💅 vsp1_isp_job_prepare(9) 💅

okay so real talk, bestie — we're in the Kernel API Manual today and the star of the show is vsp1_isp_job_prepare(9), which is a whole function in a whole kernel. grab a snack, this one's actually cute and short 🍓

✨ NAME ✨

vsp1_isp_job_prepare — prepare a new buffer transfer job 🎀 (yes that's it, that's the whole vibe, it prepares a job, slay)

🌸 SYNOPSIS 🌸

int vsp1_isp_job_prepare (struct device *dev , struct vsp1_isp_job_desc
*job );

like literally copy that exactly, no cap, the spacing and everything 💅

🦋 ARGUMENTS 🦋

  • dev — the VSP1 struct device 👑 this is the device bestie, the main character we're operating on
  • job — the job description 🎀 the actual thing you're setting up

💖 DESCRIPTION 💖

so what does it DO. okay. it prepares a new buffer transfer job by populating a display list — and that display list is gonna get executed later when someone calls vsp1_isp_job_run. it's giving "we're doing the prep work now, the performance comes later" ✨

⚠️ okay important one: all pending jobs must be released after you stop the streaming operations with a call to vsp1_isp_job_release. don't skip that part bestie, that's not optional, that's the rule 😭

and another thing, fr fr — in order for the VSPX to accept new jobs to prepare, the VSPX must have been started. like if it's not started it's just not gonna take them. no drama, just facts 🙈

🌈 RETURN 🌈

returns 0 on success or a negative error code on failure 💀 (classic kernel behaviour, love that for us)
