drm_sched_jo...d_dependency(9)

💖 NAME 💖

okay so this is the Kernel API Manual page for drm_sched_job_add_dependency — the header up top is the truncated cutie drm_sched_jo...d_dependency(9), and the whole point is literally this: it adds the fence as a job dependency. 💅✨

🌸 SYNOPSIS 🌸

int drm_sched_job_add_dependency (struct drm_sched_job *job , struct
       dma_fence *fence );

🎀 ARGUMENTS 🎀

• job — the scheduler job you’re adding the dependencies to, bestie.
• fence — the dma_fence that gets added to the list of dependencies.

🦋 DESCRIPTION 🦋

Read this part carefully, okay? Note that fence is consumed in both the success and error cases. Both. Not just when it works. 😭💀

✨ RETURN ✨

• 0 on success
• or an error on failing to expand the array
