💖 NAME 💖

dm_arm_vblank_event_pre_programming - Prepare for programming ✨

okay bestie, you're in the Kernel API Manual and this is dm_arm_vbla..._programming(9) — the page for dm_arm_vblank_event_pre_programming. It's short, it's iconic, it gets the prep done. 👑

✨ SYNOPSIS ✨

void dm_arm_vblank_event_pre_programming (struct amdgpu_crtc *acrtc ,
       struct dm_crtc_state *acrtc_state , bool pflip_update , bool
       cursor_update );

🎀 ARGUMENTS 🎀

• acrtc — The amdgpu CRTC to prepare. 💅
• acrtc_state — The new CRTC state. fresh state, fresh vibes. ✨
• pflip_update — Whether a page flip is being programmed. 🔥
• cursor_update — Whether a cursor update is being programmed. 🖱️

🌸 DESCRIPTION 🌸

So here's the vibe: this function grabs a reference on the vblank counter if a page flip or cursor update is to be programmed. 🫶 Do this before programming, so the HW is not in any idle-optimized state (such as PSR). No cap, that's the whole point. 💖

bestie, the original says it straight: do this before programming so the HW is not in any idle-optimized state (such as PSR). so yeah — prep first, periodt. ⏰
