drm_sched_j...dependencies(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_sched_job_add_implicit_dependencies(9) — like, the Kernel API Manual girlies finally got one 🎀

okay so bestie, welcome to the Kernel API Manual entry for drm_sched_j...dependencies(9) — yes the header is abbreviated, no I don't know why, and yes we're gonna get through this together. grab a strawberry drink 🍓 and let's go.

✨ NAME ✨

drm_sched_job_add_implicit_dependencies — adds implicit dependencies as job dependencies 🫶

🌸 SYNOPSIS 🌸

int drm_sched_job_add_implicit_dependencies (struct drm_sched_job *job ,
struct drm_gem_object *obj , bool write );

🦋 ARGUMENTS 🦋

  • job — the scheduler job you're adding the dependencies to. main character energy, it's receiving the deps 💖
  • obj — the gem object you're adding new dependencies from.
  • write — whether the job might write the object. and if it might? then we need to depend on shared fences in the reservation object. no cap, that's the whole bit 🔥

💜 DESCRIPTION 💜

This should be called after drm_gem_lock_reservations on your array of GEM objects used in the job, but before updating the reservations with your own fences.

like — order matters, bestie. before. not after. the way that sequencing is literally the entire vibe check 😭✨

⭐ RETURN ⭐

0 on success, or an error on failing to expand the array. that's it, that's the return 💀

like that's a whole squad and every single one of them is invited 🧚💅

ok that's the page!! it lives in ./drivers/gpu/drm/scheduler, it's dated October 2026, and the footer spells it drm_sched_j...dependencies(9) — abbreviated again, iconic behaviour honestly. go add those implicit deps, bestie, you're gonna slay 🌈✨💖
