ENUM DMUB_ABM_ACE_CURVE_TYPE(9)

💅 enum dmub_abm_ace_curve_type(9)

okay so this is a page from the Kernel API Manual and it's literally just an enum, bestie — a tiny one. Two constants, both vibing in the dmub_cmd.h header file. That's the whole tea. 🫶

---

✨ NAME ✨

enum dmub_abm_ace_curve_type — it's giving "ACE curve type." That's it, that's the description, no notes. 💅

---

🌸 SYNOPSIS 🌸

enum dmub_abm_ace_curve_type {
    ABM_ACE_CURVE_TYPE__SW ,
    ABM_ACE_CURVE_TYPE__SW_IF

};

look at her. two whole members. main character energy for a two-member enum, honestly. ✨

---

🎀 Constants 🎀

• ABM_ACE_CURVE_TYPE__SW — so the manpage literally just says -- undescribed -- for this one 😭 no cap, that's the entire entry. The docs did not come through. iykyk.
• ABM_ACE_CURVE_TYPE__SW_IF — and same situation here, bestie: -- undescribed --. two for two. the header file is the only one who actually knows, fr fr. 💀

lowkey iconic that they shipped a manpage where both constants are described as "undescribed". the audacity. the confidence. we stan a mysterious queen. 👑

like… that's a lot of siblings. this enum is the quiet one at the family reunion and honestly? relatable. 🧚

friendly reminder bestie: both constants are officially -- undescribed -- in this page, so if you need actual semantics, the header ./drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h is where the truth lives. don't @ me, i'm just the messenger 💖

and that's the page!! sign-off time: this beauty comes from ./drivers/gpu/drm/amd/display/... and the date stamp on it is October 2026, filed under enum dmub_ab...e_curve_type(9) — yes the title is truncated with ellipses in the footer, she's mysterious like that 💜 slay, go read a struct or something 🌈✨🎀
