dm_crtc_high_irq_handler(9)

💖 NAME 💖

okay so bestie, this is the dm_crtc_high_irq_handler page from the Kernel API Manual ✨ and its whole vibe is Common OTG vblank/flip event handling 💅

✨ SYNOPSIS ✨

it's giving:

void dm_crtc_high_irq_handler (struct amdgpu_device *adev , struct amdgpu_crtc *acrtc );

🎀 ARGUMENTS 🎀

• adev — amdgpu device 🫶
• acrtc — the CRTC to service. Performs writeback completion, vblank event handling, CRC processing, VRR BTR updates and pageflip completion delivery. no cap, it's doing a lot 💅

🌸 DESCRIPTION 🌸

On DCN this is driven by VUPDATE_NO_LOCK (the register latch point) from dm_vupdate_high_irq; on DCE it is driven by VLINE0 at the start of vblank from dm_crtc_high_irq. that's the whole lore ✨
