💅 dce_v6_0_average_bandwidth_vs_dram_bandwidth_for_display(9) 💅

okay so welcome to the Kernel API Manual, bestie 🎀 — today's main character is dce_v6_0_average_bandwidth_vs_dram_bandwidth_for_display, which is honestly a whole mouthful but we're gonna get through it together, i promise.

✨ NAME ✨

dce_v6_0_average_bandwidth_vs_dram_bandwidth_for_display — check average and available dram bandwidth 👑

🌸 SYNOPSIS 🌸

bool dce_v6_0_average_bandwidth_vs_dram_bandwidth_for_display (struct
       dce6_wm_params *wm );

🦋 ARGUMENTS 🦋

• wm — the watermark calculation data, like literally all of it. she's carrying the whole vibe check for the math ✨

💖 DESCRIPTION 💖

okay so here's the tea 🍓 — this function checks if the display average bandwidth actually fits in the display dram bandwidth (that's CIK, for the record). she's used for display watermark bandwidth calculations, no cap.

the returns are giving very binary icon behavior:

• returns true if the display fits 💚
• returns false if not 💀

that's it. that's the whole plot. and honestly? she ate. periodt. 🫶

ngl this is one of those little boolean gatekeepers that everything downstream depends on, so like… respect her 🌈
