get_plane_params(9)

🌸 NAME 🌸

okay so bestie, this is get_plane_params(9) from the Kernel API Manual, and it’s literally here to Get plane related params for chroma vs. luma depending on the chroma flag. that’s the whole vibe. ✨

and then there’s this iconic separator line, kept exactly as it appears:

✨ SYNOPSIS ✨

the function signature is this exact thing, no cap:

void get_plane_params (const struct
dml2_core_calcs_calculate_alternate_params *p , unsigned int plane_idx ,
bool chroma , struct plane_params *out );

🎀 ARGUMENTS 🎀

ngl, all four of these are listed as -- undescribed -- in the source, so I’m not inventing lore. periodt. 🙈

• p — undescribed 💜
• plane_idx — undescribed 💜
• chroma — undescribed 💜
• out — undescribed 💜
