✨ drm_sched_wqueue_start(9) — start scheduler submission ✨

Okay bestie, welcome to the drm_sched_wqueue_start page from the Kernel API Manual 💖 this one is short and sweet and honestly kind of a glow-up moment for your scheduler, so let's get into it.

🌸 NAME 🌸

drm_sched_wqueue_start — start scheduler submission 👑

🦋 SYNOPSIS 🦋

void drm_sched_wqueue_start (struct drm_gpu_scheduler *sched );

🎀 ARGUMENTS 🎀

• sched — the scheduler instance, aka the main character of this whole function 🫶

💅 DESCRIPTION 💅

So here's the tea: this function restarts the scheduler after drm_sched_wqueue_stop has stopped it. That's it, that's the vibe — you stopped it, now you're bringing it back. Iconic behavior honestly 💀✨

But listen, and this is the important part: this function is not necessary for 'conventional' startup. Nope, not even a little. Because the scheduler is already fully operational after drm_sched_init succeeded. So if you're out here calling this during a normal init flow, bestie… you don't need to 😭 it's giving extra.

Fr fr: only reach for this when you're un-stopping a scheduler that drm_sched_wqueue_stop put on pause. Conventional startup already ate with drm_sched_init. 👑
