dce_v10_0_a..._for_display(9)
π NAME π
ok so we're looking at dce_v10_0_average_bandwidth_vs_dram_bandwidth_for_display β that's the one that checks the average bandwidth against the available dram bandwidth, bestie. it's a Kernel API Manual situation, and the whole vibe is "does this display fit or not."
β¨ SYNOPSIS β¨
bool dce_v10_0_average_bandwidth_vs_dram_bandwidth_for_display (struct
dce10_wm_params *wm );
like, it returns a bool and takes exactly one thing. that's it. that's the whole function. π
πΈ ARGUMENTS πΈ
wmβ the watermark calculation data. that's your whole input, girl. watermark math lives in here.
π¦ DESCRIPTION π¦
okay so picture this: the function checks if the display average bandwidth actually fits inside the display dram bandwidth (CIK). that's the whole job. π
it's used for the display watermark bandwidth calculations β so it's doing the "does this even fit" math behind the scenes.
and the result? returns true if the display fits, and false if not. no in-between, no "maybe", no "it's complicated." fr fr. π
