π dce_v10_0_dram_bandwidth_for_display β NAME β¨
okay so bestie, gather round, because this is dce_v10_0_dram_bandwidth_for_display β the function that gets the dram bandwidth for display π«Ά. that's the whole vibe. she does one thing and she does it iconically.
(this little cutie lives in the Kernel API Manual, iykyk π)
πΈ SYNOPSIS πΈ
u32 dce_v10_0_dram_bandwidth_for_display (struct dce10_wm_params *wm );
literally one argument, returns a u32. no drama, no cap. π
π ARGUMENTS π
wmβ the watermark calculation data π§. that's it. that's the whole parameter. she's carrying the watermark math and she knows it.
π¦ DESCRIPTION π¦
okay so what does she actually do? she calculates the dram bandwidth used for display (CIK) β¨. no like seriously, that's the job.
this is used for display watermark bandwidth calculations π β the watermark girlies could never do their thing without her.
and what does she give you back? she returns the dram bandwidth for display in MBytes/s π₯. yes bestie, MBytes/s. not bytes, not GBytes, MBytes. write it down. π
ngl this is the kind of function that looks tiny and then turns out to be lowkey load-bearing for the entire watermark pipeline. main character energy fr fr π

and where does she live? π in the kernel file ./drivers/gpu/drm/amd/amdgpu/dce_v10_0.c β go say hi, she's literally right there.
okay that's the whole page, mwah π β sourced from ./drivers/gpu/drm/amd/amdgpu, dated October 2026. slay, go read the rest of the docs bestie, ily πβ¨
