ENUM DRM_PANEL_ORIENTATION(9)

💅 NAME 💅

Okay bestie, welcome to the <enum drm_panel_orientation> page from the Kernel API Manual — this is the one that gives you panel_orientation info for &drm_display_info, and we are going to make it make sense, fr fr. ✨

🎀 SYNOPSIS 🎀

enum drm_panel_orientation {
    DRM_MODE_PANEL_ORIENTATION_UNKNOWN ,
    DRM_MODE_PANEL_ORIENTATION_NORMAL ,
    DRM_MODE_PANEL_ORIENTATION_BOTTOM_UP ,
    DRM_MODE_PANEL_ORIENTATION_LEFT_UP ,
    DRM_MODE_PANEL_ORIENTATION_RIGHT_UP

};

🌸 Constants 🌸

• DRM_MODE_PANEL_ORIENTATION_UNKNOWN — the drm driver has not provided any panel orientation information (normal for non panels). In this case, the "panel orientation" connector prop will not be attached. 💀
• DRM_MODE_PANEL_ORIENTATION_NORMAL — the top side of the panel matches the top side of the device’s casing. Slay, no rotation drama. 💅
• DRM_MODE_PANEL_ORIENTATION_BOTTOM_UP — the top side of the panel matches the bottom side of the device’s casing, iow the panel is mounted upside-down. 🙈
• DRM_MODE_PANEL_ORIENTATION_LEFT_UP — the left side of the panel matches the top side of the device’s casing. Iconic sideways moment. 🦋
• DRM_MODE_PANEL_ORIENTATION_RIGHT_UP — the right side of the panel matches the top side of the device’s casing. Another sideways queen. 👑

🫶 Description 🫶

This enum is used to track the (LCD) panel orientation. There are no separate #defines for the uapi! 👀 That part is important, bestie — do not go looking for extra #define besties that aren’t there. 💖
