drm_sched_select_entity(9)

💖 drm_sched_select_entity(9) 💖

okay bestie, welcome to the Kernel API Manual entry for drm_sched_select_entity — the function that selects the next entity to process. It’s giving tiny-but-iconic scheduler moment, and we’re covering every single deet, no cap ✨

🌸 NAME 🌸

drm_sched_select_entity — Select next entity to process 💅

✨ SYNOPSIS ✨

struct drm_sched_entity * drm_sched_select_entity (struct
drm_gpu_scheduler *sched );

🎀 ARGUMENTS 🎀

• sched — scheduler instance 🫶

🦋 DESCRIPTION 🦋

It returns an entity to process, or NULL if none are found. That’s the whole deal, bestie.

note time: we break out of the for-loop when entity is non-null, which can also be an error-pointer — this is what assures we don’t process lower priority run-queues. See comments in the respectively called functions for the full tea 💅
