ENUM DMUB_CMD_PANEL_CNTL_TYPE(9)

✨ enum dmub_cmd_panel_cntl_type(9) ✨

okay bestie, welcome to the Kernel API Manual page for enum dmub_cmd_panel_cntl_type(9) — yes, the manual name is literally Kernel API Manual, and this whole page is about a panel-control command enum. No cap, we're doing this 💅.

🌸 NAME 🌸

enum dmub_cmd_panel_cntl_type — panel control command. That's the name line, periodt: it's an enum for a panel control command.

🦋 SYNOPSIS 🦋

Here's the exact shape of the enum, bestie — the spaces before the commas and the blank line are part of the look, so don't come for me:

enum dmub_cmd_panel_cntl_type {
    DMUB_CMD__PANEL_CNTL_HW_INIT ,
    DMUB_CMD__PANEL_CNTL_QUERY_BACKLIGHT_INFO ,
    DMUB_CMD__PANEL_DEBUG_PWM_FREQ

};

🎀 Constants 🎀

Three constants, and the manpage is literally giving us -- undescribed -- for every single one. Not me being lazy — the docs are ghosting us 😭.

• DMUB_CMD__PANEL_CNTL_HW_INIT — -- undescribed --. That's it. That's the description. Iconic in a mysterious way 💀.
• DMUB_CMD__PANEL_CNTL_QUERY_BACKLIGHT_INFO — -- undescribed --. Same energy, no extra lore.
• DMUB_CMD__PANEL_DEBUG_PWM_FREQ — -- undescribed --. The manpage said "no thoughts, head empty" on this one too.

🌈 SEE ALSO 🌈

First up, the kernel file is ./drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h — that's the path the original page points at, iykyk. And here are all the SEE ALSO references, same names, same (9), no edits, no merging, no invented faves:

okay that's the whole page, bestie! mwah 💋 — source/version: ./drivers/gpu/drm/amd/display/... · date: October 2026 · and the footer also carries enum dmub_c...el_cntl_type(9), so that's the whole footer vibe. 🫶
