drm/edid: Parse AMD Vendor-Specific Data Block

2026-04-03T17:45:49+00:00

Parse the AMD VSDB v3 from CTA extension blocks and store the result in struct drm_amd_vsdb_info, a new field of drm_display_info. This includes replay mode, panel type, and luminance ranges. Signed-off-by: Chenyu Chen Reviewed-by: Mario Limonciello (AMD) Signed-off-by: Alex Deucher

drm/display: hdmi: Use drm_output_color_format instead of hdmi_colorspace

2026-03-24T12:54:35+00:00

The hdmi_colorspace enum was defined to represent the colorspace value of the HDMI infoframes. It was later used by some HDMI drivers to express the output format they should be setting up. During the introduction of the HDMI helpers, it then was used to represent it in the drm_connector_hdmi_state structure. However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_* defines, and now with the drm_output_color_format enum. Let's consolidate around drm_output_color_format in drm_connector_hdmi_state to facilitate the current effort to provide a global output format selection mechanism.

drm/connector: Remove DRM_COLOR_FORMAT defines

2026-03-24T12:54:35+00:00

Now that all users of DRM_COLOR_FORMAT_* defines have been converted to the new enum, we can get rid of those defines. Acked-by: Jani Nikula Reviewed-by: Dmitry Baryshkov Link: https://lore.kernel.org/r/20260305-drm-rework-color-formats-v3-13-f3935f6db579@kernel.org Signed-off-by: Maxime Ripard

drm/connector: Introduce drm_output_color_format enum

2026-03-24T12:54:28+00:00

The EDID parsing code initially introduced the DRM_COLOR_FORMAT_* defines to represent the sink capabilities. Since a given sink could support multiple formats, it was first defined as a bitmask. However, the core and drivers have since leveraged those defines to represent both the supported formats but also the current format being used. Considering the latter case, the more natural, and consistent, thing to do would be to create an enum of all the possible formats, and then list the supported formats using a bitmask of the individual enum values. Let's create a new enum following that pattern, drm_output_color_format, while maintaining the DRM_COLOR_FORMAT_* compatibility to make the transition easier.

drm/connector: Add a new 'panel_type' property

2026-01-27T18:57:24+00:00

If the driver can make an assertion whether a connected panel is an OLED panel or not then it can attach a property to the connector that userspace can use as a hint for color schemes.

drm/display: hdmi_state_helper: split InfoFrame functions per type

2026-01-19T11:11:46+00:00

Havign a single set of InfoFrame callbacks doesn't provide enough information to the DRM framework about the InfoFrame types that are actually supported. Also it's not really future-proof: it provides a way to program only a single Vendor-Specific frame, however we might need to support multiple VSIs at the same time (e.g. HDMI vs HDMI Forum VSIs). Provide separate sets of callbacks, one per the InfoFrame type.

drm/connector: make clear_infoframe callback mandatory for HDMI connectors

2026-01-19T11:10:35+00:00

We already require both hdmi_write_infoframe and hdmi_clear_infoframe for bridges implementing DRM_BRIDGE_OP_HDMI. It makes sense to require the clear_infoframes callback for HDMI connectors utilizing drmm_connector_hdmi_init().
