dce8_dram_bandwidth(9)

💖 NAME 💖

okay so this is dce8_dram_bandwidth from the Kernel API Manual, and the name is literally dce8_dram_bandwidth - get the dram bandwidth. that's the whole mission, bestie: it gets the dram bandwidth. periodt. 💅✨

✨ SYNOPSIS ✨

here's the signature — copy it exactly, no freestyling:

u32 dce8_dram_bandwidth (struct dce8_wm_params *wm );

🎀 ARGUMENTS 🎀

• wm — watermark calculation data. that's the one argument, and it's giving watermark calculation data energy 🫶

🦋 DESCRIPTION 🦋

okay so this one calculates the raw dram bandwidth (CIK). yes, that's the vibe. it's used for display watermark bandwidth calculations 🌸 and then it Returns the dram bandwidth in MBytes/s. slay, honestly 🔥
