ENUM DC_CURSOR_COLOR_FORMAT(9)

💅 enum dc_cursor_color_format — DC cursor programming mode

ok so this is a page from the Kernel API Manual, and today's main character is enum dc_cursor_color_format 🎀 — genuinely one of those little enums that decides how your mouse pointer looks. no cap, it's giving "small but powerful."

---

✨ SYNOPSIS ✨

like, here's the whole squad, all six of them, and yes you get every single one:

enum dc_cursor_color_format {
    CURSOR_MODE_MONO ,
    CURSOR_MODE_COLOR_1BIT_AND ,
    CURSOR_MODE_COLOR_PRE_MULTIPLIED_ALPHA ,
    CURSOR_MODE_COLOR_UN_PRE_MULTIPLIED_ALPHA ,
    CURSOR_MODE_COLOR_64BIT_FP_PRE_MULTIPLIED ,
    CURSOR_MODE_COLOR_64BIT_FP_UN_PRE_MULTIPLIED

};

🌸 Constants 🌸

okay bestie, i have to be so honest with you rn — the source doc did us dirty and literally describes none of these. so here's the full roster, and none of them came with a description. i'm not gonna make anything up, that's not the vibe 💀

• CURSOR_MODE_MONO — -- undescribed -- 🙈
• CURSOR_MODE_COLOR_1BIT_AND — -- undescribed -- 🙈
• CURSOR_MODE_COLOR_PRE_MULTIPLIED_ALPHA — -- undescribed -- 🙈
• CURSOR_MODE_COLOR_UN_PRE_MULTIPLIED_ALPHA — -- undescribed -- 🙈
• CURSOR_MODE_COLOR_64BIT_FP_PRE_MULTIPLIED — -- undescribed -- 🙈
• CURSOR_MODE_COLOR_64BIT_FP_UN_PRE_MULTIPLIED — -- undescribed -- 🙈

like… the audacity. but we move 💅

🦋 Description 🦋

okay so what does it do — this enum is for programming the CURSOR_MODE register field. that's the whole job. icon behavior.

and the tea is: what that register should actually be programmed to depends on the OS requested cursor shape flags and what we stored in the cursor surface. so it's not a one-size-fits-all situation — the answer changes based on those two things. iykyk ✨

🔥 SEE ALSO 🔥

go look at these next, bestie, they're part of the same friend group:

• Kernel file ./drivers/gpu/drm/amd/display/dc/dc_hw_types.h
• struct dc_cursor_position(9)
• struct dc_crtc_timing(9)

🫶 so yeah, that's the whole page! this lil' beauty lives in ./drivers/gpu/drm/amd/display/dc, the version stamp says October 2026, and it's filed under enum dc_cursor_color_format(9) in the Kernel API Manual. slay, go program that cursor register. periodt. 👑🌈
