ENUM MALI_C55_AEXP_HIST_PLANE_MODE(9)

💅 NAME 💅

enum mali_c55_aexp_hist_plane_mode — the mode for the AEXP Histograms ✨

okay so real talk, bestie, we're deep in the Kernel API Manual right now and this is the enum that tells the AEXP histogram hardware how to slice up your colour planes. it's giving "small enum, big responsibility" energy and honestly? iconic. 🎀

🌸 SYNOPSIS 🌸

enum mali_c55_aexp_hist_plane_mode {
    MALI_C55_AEXP_HIST_COMBINED ,
    MALI_C55_AEXP_HIST_SEPARATE ,
    MALI_C55_AEXP_HIST_FOCUS_00 ,
    MALI_C55_AEXP_HIST_FOCUS_01 ,
    MALI_C55_AEXP_HIST_FOCUS_10 ,
    MALI_C55_AEXP_HIST_FOCUS_11

};

✨ CONSTANTS ✨

• MALI_C55_AEXP_HIST_COMBINED — every colour plane gets squished into one single 1024-bin histogram. all together now, fr fr. 🫶
• MALI_C55_AEXP_HIST_SEPARATE — each colour plane gets its own 256-bin histogram, and the bin width is 16. separate but equal, we love to see it. 💖
• MALI_C55_AEXP_HIST_FOCUS_00 — the top left plane goes in the first bank, and the rest go in the second bank. main character plane energy. 👑
• MALI_C55_AEXP_HIST_FOCUS_01 — the top right plane in the first bank, rest in second bank. yes queen, get that spotlight. ⭐
• MALI_C55_AEXP_HIST_FOCUS_10 — the bottom left plane in the first bank, rest in second bank. lowkey the underrated one. 🦋
• MALI_C55_AEXP_HIST_FOCUS_11 — the bottom right plane in the first bank, rest in second bank. saving the best for last, periodt. 🔥

📖 DESCRIPTION 📖

so in the "focus" modes, the statistics get collected into two 512-bin histograms with a bin width of 8. one single colour plane lives in the first histogram, and the remainder get combined into the second one. that's the whole vibe check.

and the four focus options? they literally just represent which of the four positions in a bayer pattern is the focused plane. that's it, that's the lore. iykyk. 🙈
