ENUM DMUB_SHARED_STATE_FEATURE_ID(9)

✨ NAME ✨

enum dmub_shared_state_feature_id — bestie, it's literally just the List of shared state features 💅

(also hi, you're in the Kernel API Manual, section 9, welcome to the function-party 🎀)

---

🌸 SYNOPSIS 🌸

ok so here's the whole vibe, in code, exactly as it is:

enum dmub_shared_state_feature_id {
    DMUB_SHARED_SHARE_FEATURE__INVALID ,
    DMUB_SHARED_SHARE_FEATURE__IPS_FW ,
    DMUB_SHARED_SHARE_FEATURE__IPS_DRIVER ,
    DMUB_SHARED_SHARE_FEATURE__DEBUG_SETUP ,
    DMUB_SHARED_STATE_FEATURE__CURSOR_OFFLOAD_V1 ,
    DMUB_SHARED_STATE_FEATURE__LAST

};

no cap, that's the whole thing 🫶

---

🦋 Constants 🦋

so these are the members of the enum, and bestie i have to be so fr with you: the source doc gives no description for any of them. like, -- undescribed -- energy for every single one 😭 i'm not gonna make stuff up, so here they are with their honest little blank labels:

• DMUB_SHARED_SHARE_FEATURE__INVALID — no description given (-- undescribed --) 🙈
• DMUB_SHARED_SHARE_FEATURE__IPS_FW — no description given (-- undescribed --) 🙈
• DMUB_SHARED_SHARE_FEATURE__IPS_DRIVER — no description given (-- undescribed --) 🙈
• DMUB_SHARED_SHARE_FEATURE__DEBUG_SETUP — no description given (-- undescribed --) 🙈
• DMUB_SHARED_STATE_FEATURE__CURSOR_OFFLOAD_V1 — no description given (-- undescribed --) 🙈
• DMUB_SHARED_STATE_FEATURE__LAST — no description given (-- undescribed --) 🙈

yes, the first four say SHARE and the last two say STATE — that is genuinely how they're spelled in the source, and we do not "fix" it, we respect the bit 🫡 icons only

ok that's the whole page, go read the header file bestie, it's giving lore 🌈

sign-off time 🎀 this one's from ./drivers/gpu/drm/amd/display/... — the source path is literally truncated with ... in the footer, iconic honestly 💀 — dated October 2026, and the page is enum dmub_s...e_feature_id(9) (also truncated, love that for us). mwah 💋
