STRUCT GSC_PIX_MAX(9)

💅 struct gsc_pix_max(9) — the Kernel API Manual, but make it cute

okay so bestie, welcome to struct gsc_pix_max(9) — this is the page about image pixel size limits in various IP configurations. that's it, that's the vibe. it's the little struct that tells you how big a picture is allowed to get depending on which blocks of the pipeline are switched on. slay. 🎀

✨ SYNOPSIS ✨

here's the whole glow-up, exactly as declared:

struct gsc_pix_max {
    u16 org_scaler_bypass_w;
    u16 org_scaler_bypass_h;
    u16 org_scaler_input_w;
    u16 org_scaler_input_h;
    u16 real_rot_dis_w;
    u16 real_rot_dis_h;
    u16 real_rot_en_w;
    u16 real_rot_en_h;
    u16 target_rot_dis_w;
    u16 target_rot_dis_h;
    u16 target_rot_en_w;
    u16 target_rot_en_h;
 };

twelve u16s and every single one of them is a max-pixel budget for a different configuration. no cap, it's giving "spreadsheet of limits but make it hardware." 💀

🌸 Members 🌸

okay so let's go through the cast, one icon at a time:

• org_scaler_bypass_w — max pixel width when the scaler is disabled 🚫
• org_scaler_bypass_h — max pixel height when the scaler is disabled 🚫
• org_scaler_input_w — max pixel width when the scaler is enabled ✅
• org_scaler_input_h — max pixel height when the scaler is enabled ✅
• real_rot_dis_w — max pixel src cropped height with the rotator is off 🌀

ngl bestie, yes, the _w one says "height" — that's literally what the page says, so i'm not gonna gaslight you and change it. iykyk. 👀

• real_rot_dis_h — max pixel src cropped width with the rotator is off 🌀
• real_rot_en_w — max pixel src cropped width with the rotator is on 🔄
• real_rot_en_h — max pixel src cropped height with the rotator is on 🔄
• target_rot_dis_w — max pixel dst scaled width with the rotator is off 🎯
• target_rot_dis_h — max pixel dst scaled height with the rotator is off 🎯
• target_rot_en_w — max pixel dst scaled width with the rotator is on 🎯
• target_rot_en_h — max pixel dst scaled height with the rotator is on 🎯

periodt. twelve members, twelve limits, zero skips. you're so welcome. 💖

🧚 a lil heads-up: this struct only describes the limits, it doesn't enforce anything by itself — that's somebody else's main character energy.
