💅 dpu_core_pe...c_release_bw(9) — Kernel API Manual ✨

okay bestie, welcome to the dpu_core_pe...c_release_bw(9) page from the Kernel API Manual. This one is short, sweet, and lowkey iconic. 🎀

🎀 NAME

dpu_core_perf_crtc_release_bw — literally “request zero bandwidth.” That’s the whole assignment, no cap. 💅

✨ SYNOPSIS

void dpu_core_perf_crtc_release_bw (struct drm_crtc *crtc );

🫶 ARGUMENTS

• crtc — a pointer to a crtc. That’s it. That’s the argument. 🦋

💖 DESCRIPTION

So here’s the vibe: the function checks a state variable for the crtc. If all pending commit requests are done — meaning no more bandwidth is needed — it’s time to release bandwidth request. Periodt. ✨

Like, it’s giving “wrap up the bandwidth request once the commits are finished,” and honestly? We love a tidy function. 💜
