g2d_wait_finish(9)

💅 g2d_wait_finish(9) — from the Kernel API Manual 💅

🌸 NAME 🌸

g2d_wait_finish — bestie, this is literally the “wait for the G2D engine to finish the current runqueue node” function. That’s the vibe. ✨

🦋 SYNOPSIS 🦋

void g2d_wait_finish (struct g2d_data *g2d , struct drm_file *file );

🎀 ARGUMENTS 🎀

• g2d — the G2D state object, iconic little struct, literally carrying the engine’s whole situation 💖
• file — if it’s not zero, only wait when the current runqueue node belongs to the DRM file. That’s the condition, periodt 🫶

🔥 DESCRIPTION 🔥

Okay so here’s the tea: should the engine not become idle after a 100ms timeout, a hardware reset is issued. That’s it — 100ms, then boom, hardware reset. 💀
