drm/drm_crtc: Introduce sharpness strength property

2025-10-30T13:38:04Z

Introduce a new crtc property "SHARPNESS_STRENGTH" that allows the user to set the intensity so as to get the sharpness effect. The value of this property can be set from 0-255. It is useful in scenario when the output is blurry and user want to sharpen the pixels. User can increase/decrease the sharpness level depending on the content displayed. v2: Rename crtc property variable [Arun] Add modeset detail in uapi doc[Uma] v3: Fix build issue v4: Modify the subject line[Ankit] Signed-off-by: Nemesa Garg Reviewed-by: Ankit Nautiyal Tested-by: Adarsh G M Acked-by: Simona Vetter Link: https://invent.kde.org/plasma/kwin/-/merge_requests/7689 Link: https://patch.msgid.link/20251028120747.3027332-2-ankit.k.nautiyal@intel.com Signed-off-by: Jani Nikula

drm: add clone mode check for CRTC

2025-01-07T23:39:58Z

Add a common helper to check if the given CRTC state is in clone mode. This can be used by drivers to help detect if a CRTC is being shared by multiple encoders Signed-off-by: Jessica Zhang Reviewed-by: Abhinav Kumar Reviewed-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20241216-concurrent-wb-v4-1-fe220297a7f0@quicinc.com Signed-off-by: Dmitry Baryshkov

drm: Rename drm_plane_check_pixel_format() to drm_plane_has_format()

2024-06-24T14:08:33Z

Rename drm_plane_check_pixel_format() to drm_plane_has_format() and change the return type accordingly. Allows one to write more natural code. Also matches drm_any_plane_has_format() better.

drm: prefer DRM_MODE_FMT/ARG over drm_mode_debug_printmodeline()

2024-04-15T13:22:50Z

We have DRM_MODE_FMT and DRM_MODE_ARG() macros to allow unified debug printing of modes in any printk-formatted logging. Prefer them over drm_mode_debug_printmodeline(). This allows drm device specific logging of modes, in the right drm debug category, and inline with the rest of the logging instead of split to multiple lines.

drm: Remove drm_num_crtcs() helper

2024-02-28T11:18:07Z

The drm_num_crtcs() helper determines the number of CRTCs by iterating over the list of CRTCs that have been registered with the mode config. However, we already keep track of that number in the mode config's num_crtcs field, so we can simply retrieve the value from that and remove the extra helper function.

drm/crtc: fix uninitialized variable use

2023-12-08T14:47:39Z

Commit 3823119b9c2b ("drm/crtc: Fix uninit-value bug in drm_mode_setcrtc") was supposed to fix use of an uninitialized variable, but introduced another. num_connectors is only initialized if crtc_req->count_connectors > 0, but it's used regardless. Fix it.
