Detailed Description
struct drm_display_info - runtime data about the connected sink
Describes a given display (e.g. CRT or flat panel) and its limitations. For fixed display sinks like built-in panels there's not much difference between this and &struct drm_connector. But for sinks with a real cable this structure is meant to describe all the things at the other end of the cable.
For sinks which provide an EDID this can be filled out by calling drm_add_edid_modes().
Member Data Documentation
◆ amd_vsdb
| struct drm_amd_vsdb_info drm_display_info::amd_vsdb |
@amd_vsdb: AMD-specific VSDB information.
◆ bpc
| unsigned int drm_display_info::bpc |
@bpc: Maximum bits per color channel. Used by HDMI and DP outputs.
◆ bus_flags
| u32 drm_display_info::bus_flags |
@bus_flags: Additional information (like pixel signal polarity) for the pixel data on the bus, using &enum drm_bus_flags values DRM_BUS_FLAGS_.
◆ bus_formats
| const u32* drm_display_info::bus_formats |
@bus_formats: Pixel data format on the wire, somewhat redundant with @color_formats. Array of size @num_bus_formats encoded using MEDIA_BUS_FMT_ defines shared with v4l and media drivers.
◆ cea_rev
| u8 drm_display_info::cea_rev |
@cea_rev: CEA revision of the HDMI sink.
◆ color_formats
| u32 drm_display_info::color_formats |
@color_formats: HDMI Color formats, selects between RGB and YCbCr modes. Uses a bitmask of DRM_OUTPUT_COLOR_FORMAT_ defines, which are not the same ones as used to describe the pixel format in framebuffers, and also don't match the formats in @bus_formats which are shared with v4l.
◆ dvi_dual
| bool drm_display_info::dvi_dual |
@dvi_dual: Dual-link DVI sink?
◆ edid_hdmi_rgb444_dc_modes
| u8 drm_display_info::edid_hdmi_rgb444_dc_modes |
@edid_hdmi_rgb444_dc_modes: Mask of supported hdmi deep color modes in RGB 4:4:4. Even more stuff redundant with @bus_formats.
◆ edid_hdmi_ycbcr444_dc_modes
| u8 drm_display_info::edid_hdmi_ycbcr444_dc_modes |
@edid_hdmi_ycbcr444_dc_modes: Mask of supported hdmi deep color modes in YCbCr 4:4:4. Even more stuff redundant with @bus_formats.
◆ has_audio
| bool drm_display_info::has_audio |
@has_audio: True if the sink supports audio.
This field shall be used instead of calling drm_detect_monitor_audio() when possible.
◆ has_hdmi_infoframe
| bool drm_display_info::has_hdmi_infoframe |
@has_hdmi_infoframe: Does the sink support the HDMI infoframe?
◆ hdmi
| struct drm_hdmi_info drm_display_info::hdmi |
@hdmi: advance features of a HDMI sink.
◆ hdr_sink_metadata
| struct hdr_sink_metadata drm_display_info::hdr_sink_metadata |
@hdr_sink_metadata: HDR Metadata Information read from sink
◆ height_mm
| unsigned int drm_display_info::height_mm |
@height_mm: Physical height in mm.
◆ is_hdmi
| bool drm_display_info::is_hdmi |
@is_hdmi: True if the sink is an HDMI device.
This field shall be used instead of calling drm_detect_hdmi_monitor() when possible.
◆ luminance_range
| struct drm_luminance_range_info drm_display_info::luminance_range |
@luminance_range: Luminance range supported by panel
◆ max_dsc_bpp
| u32 drm_display_info::max_dsc_bpp |
@max_dsc_bpp: Maximum DSC target bitrate, if it is set to 0 the monitor's default value is used instead.
◆ max_tmds_clock
| int drm_display_info::max_tmds_clock |
@max_tmds_clock: Maximum TMDS clock rate supported by the sink in kHz. 0 means undefined.
◆ monitor_range
| struct drm_monitor_range_info drm_display_info::monitor_range |
@monitor_range: Frequency range supported by monitor range descriptor
◆ mso_pixel_overlap
| u8 drm_display_info::mso_pixel_overlap |
@mso_pixel_overlap: eDP MSO segment pixel overlap, 0-8 pixels.
◆ mso_stream_count
| u8 drm_display_info::mso_stream_count |
@mso_stream_count: eDP Multi-SST Operation (MSO) stream count from the DisplayID VESA vendor block. 0 for conventional Single-Stream Transport (SST), or 2 or 4 MSO streams.
◆ non_desktop
| bool drm_display_info::non_desktop |
@non_desktop: Non desktop display (HMD).
◆ num_bus_formats
| unsigned int drm_display_info::num_bus_formats |
@num_bus_formats: Size of @bus_formats array.
◆ panel_orientation
| int drm_display_info::panel_orientation |
@panel_orientation: Read only connector property for built-in panels, indicating the orientation of the panel vs the device's casing. drm_connector_init() sets this to DRM_MODE_PANEL_ORIENTATION_UNKNOWN. When not UNKNOWN this gets used by the drm_fb_helpers to rotate the fb to compensate and gets exported as prop to userspace.
◆ quirks
| u32 drm_display_info::quirks |
@quirks: EDID based quirks. DRM core and drivers can query the @drm_edid_quirk quirks using drm_edid_has_quirk(), the rest of the quirks also tracked here are internal to EDID parsing.
◆ rgb_quant_range_selectable
| bool drm_display_info::rgb_quant_range_selectable |
@rgb_quant_range_selectable: Does the sink support selecting the RGB quantization range?
◆ source_physical_address
| u16 drm_display_info::source_physical_address |
@source_physical_address: Source Physical Address from HDMI Vendor-Specific Data Block, for CEC usage.
Defaults to CEC_PHYS_ADDR_INVALID (0xffff).
◆ subpixel_order
| enum subpixel_order drm_display_info::subpixel_order |
@subpixel_order: Subpixel order of LCD panels.
◆ vics
| u8* drm_display_info::vics |
@vics: Array of vics_len VICs. Internal to EDID parsing.
◆ vics_len
| int drm_display_info::vics_len |
@vics_len: Number of elements in vics. Internal to EDID parsing.
◆ width_mm
| unsigned int drm_display_info::width_mm |
@width_mm: Physical width in mm.
