drm_sched_job_arm(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to drm_sched_job_arm(9) from the Kernel API Manual ✨ this one is short but it's lowkey the "arm the job" moment, and you cannot skip it. no cap. 💅

🌸 NAME 🌸

drm_sched_job_arm — arm a scheduler job for execution 🎀

✨ SYNOPSIS ✨

void drm_sched_job_arm (struct drm_sched_job *job );

🦋 ARGUMENTS 🦋

  • job — the scheduler job to arm. that's the whole assignment, bestie. 🫶

💖 DESCRIPTION 💖

This arms a scheduler job for execution. like, actually arms it — glow-up complete. ✨ Specifically, it initializes the drm_sched_job.s_fence of job, so that it can be attached to struct dma_resv or other places that need to track the completion of this job. 🎀

It also initializes sequence numbers, which are fundamental for fence ordering. order matters, iykyk. 🧚

For locking considerations, refer to the drm_sched_entity_push_job documentation. 🔐

🚨 bestie, listen: once this function was called, you must submit job with drm_sched_entity_push_job. not "maybe", not "later", not "when I feel like it". must. periodt. 💀

This can only be called if drm_sched_job_init succeeded. if init didn't succeed, this is not the move. 🙈
