💅 dce_v8_0_check_latency_hiding — kernel API manual, section 9 🎀

okay so bestie, we're in the Kernel API Manual (section 9, the kernel-functions girlies) and today's main character is dce_v8_0_check_latency_hiding. no cap, it's a whole vibe.

✨ NAME ✨

dce_v8_0_check_latency_hiding — check latency hiding 🦋

🌸 SYNOPSIS 🌸

bool dce_v8_0_check_latency_hiding (struct dce8_wm_params *wm );

🎀 ARGUMENTS 🎀

• wm — the watermark calculation data. that's it, that's the whole argument. she's the passport, she's the ~vibes~, she's everything the function needs to do her little check 💖

👑 DESCRIPTION 👑

so, what does she actually do? she checks latency hiding — and before you ask, yes, this is the CIK flavor of that check. (CIK, iykyk. 💅)

she's the one who gets pulled in for display watermark bandwidth calculations — that whole pipeline where the display is like "bestie do I have enough bandwidth" and this function is the vibe check that answers.

and her answer is literally just a bool, which is so iconic of her:

• returns true if the display fits ✅
• returns false if it doesn't ❌

that's the entire personality. no side quests, no drama, just a yes or a no and she's out. periodt. 💀

fr fr though — true = display fits, false = display does not fit. do not mix these up, bestie, the whole bandwidth calculation is gonna be looking at you funny. 😭
