drm/amdgpu: Fix function header names in amdgpu_connectors.c

2025-11-24T09:29:55+00:00

commit 38ab33dbea594700c8d6cc81eec0a54e95d3eb2f upstream. Align the function headers for `amdgpu_max_hdmi_pixel_clock` and `amdgpu_connector_dvi_mode_valid` with the function implementations so they match the expected kdoc style. Fixes the below: drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c:1199: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst * Returns the maximum supported HDMI (TMDS) pixel clock in KHz. drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c:1212: warning: This comment starts with '/**', but isn't a kernel-doc comment.

drm/amdgpu: Respect max pixel clock for HDMI and DVI-D (v2)

2025-11-24T09:29:31+00:00

[ Upstream commit 585b2f685c56c5095cc22c7202bf74d8e9a73cdd ] Update the legacy (non-DC) display code to respect the maximum pixel clock for HDMI and DVI-D. Reject modes that would require a higher pixel clock than can be supported. Also update the maximum supported HDMI clock value depending on the ASIC type. For reference, see the DC code: check max_hdmi_pixel_clock in dce*_resource.c v2: Fix maximum clocks for DVI-D and DVI/HDMI adapters.

drm/amdgpu: Remove unnecessary include statements for drm_crtc_helper.h

2023-01-18T08:25:30+00:00

Several source files include drm_crtc_helper.h without needing it or only to get its transitive include statements; leading to unnecessary compile-time dependencies. Directly include required headers and drop drm_crtc_helper.h where possible. v2: * keep includes sorted in amdgpu_device.c (Sam) Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Acked-by: Jani Nikula Acked-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20230116131235.18917-4-tzimmermann@suse.de

drm/amdgpu: Retry DDC probing on DVI on failure if we got an HPD interrupt

2023-01-05T16:42:09+00:00

HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. Rescheduling the hotplug work for a second when we run into an HPD signal with a failing DDC probe usually gives enough time for the rest of the connector's pins to make contact, and fixes this issue.

drm/amdgpu: Partially revert "drm/amdgpu: update drm_display_info correctly when the edid is read"

2022-11-23T15:31:31+00:00

This partially reverts 20543be93ca45968f344261c1a997177e51bd7e1. Calling drm_connector_update_edid_property() in amdgpu_connector_free_edid() causes a noticeable pause in the system every 10 seconds on polled outputs so revert this part of the change.

drm: Rename dp/ to display/

2022-04-25T09:17:45+00:00

Rename dp/ to display/ to account for additional display-related helpers, such as HDMI. Update all related include statements. No functional changes. Various drivers, such as i915 and amdgpu, use similar naming scheme by putting code for video-output standards into a local display/ directory. The new directory's name is aligned with this convention. v2: * update commit message (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Lyude Paul Reviewed-by: Javier Martinez Canillas Reviewed-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-3-tzimmermann@suse.de
