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] Signed-off-by: Nemesa Garg --- drivers/gpu/drm/drm_atomic_uapi.c | 4 ++++ drivers/gpu/drm/drm_crtc.c | 35 +++++++++++++++++++++++++++++++ include/drm/drm_crtc.h | 17 +++++++++++++++ 3 files changed, 56 insertions(+) diff --git a/drivers/gpu/drm/drm_atomic_uapi.c b/drivers/gpu/drm/drm_atomic_uapi.c index 370dc676e3aa..b482bc2b5d0a 100644 --- a/drivers/gpu/drm/drm_atomic_uapi.c +++ b/drivers/gpu/drm/drm_atomic_uapi.c @@ -417,6 +417,8 @@ static int drm_atomic_crtc_set_property(struct drm_crtc *crtc, set_out_fence_for_crtc(state->state, crtc, fence_ptr); } else if (property == crtc->scaling_filter_property) { state->scaling_filter = val; + } else if (property == crtc->sharpness_strength_property) { + state->sharpness_strength = val; } else if (crtc->funcs->atomic_set_property) { return crtc->funcs->atomic_set_property(crtc, state, property, val); } else { @@ -454,6 +456,8 @@ drm_atomic_crtc_get_property(struct drm_crtc *crtc, *val = 0; else if (property == crtc->scaling_filter_property) *val = state->scaling_filter; + else if (property == crtc->sharpness_strength_property) + *val = state->sharpness_strength; else if (crtc->funcs->atomic_get_property) return crtc->funcs->atomic_get_property(crtc, state, property, val); else { diff --git a/drivers/gpu/drm/drm_crtc.c b/drivers/gpu/drm/drm_crtc.c index 3488ff067c69..c4a267fa3402 100644 --- a/drivers/gpu/drm/drm_crtc.c +++ b/drivers/gpu/drm/drm_crtc.c @@ -229,6 +229,25 @@ struct dma_fence *drm_crtc_create_fence(struct drm_crtc *crtc) * Driver's default scaling filter * Nearest Neighbor: * Nearest Neighbor scaling filter + * SHARPNESS_STRENGTH: + * Atomic property for setting the sharpness strength/intensity by userspace. + * + * The value of this property is set as an integer value ranging + * from 0 - 255 where: + * + * 0 means feature is disabled. + * + * 1 means minimum sharpness. + * + * 255 means maximum sharpness. + * + * User can gradually increase or decrease the sharpness level and can + * set the optimum value depending on content and this value will be + * passed to kernel through the Uapi. + * The setting of this property does not require modeset. + * The sharpness effect takes place post blending on the final composed output. + * If the feature is disabled, the content remains same without any sharpening effect + * and when this feature is applied, it enhances the clarity of the content. */ __printf(6, 0) @@ -939,3 +958,19 @@ int drm_crtc_create_scaling_filter_property(struct drm_crtc *crtc, return 0; } EXPORT_SYMBOL(drm_crtc_create_scaling_filter_property); + +int drm_crtc_create_sharpness_strength_property(struct drm_crtc *crtc) +{ + struct drm_device *dev = crtc->dev; + struct drm_property *prop = + drm_property_create_range(dev, 0, "SHARPNESS_STRENGTH", 0, 255); + + if (!prop) + return -ENOMEM; + + crtc->sharpness_strength_property = prop; + drm_object_attach_property(&crtc->base, prop, 0); + + return 0; +} +EXPORT_SYMBOL(drm_crtc_create_sharpness_strength_property); diff --git a/include/drm/drm_crtc.h b/include/drm/drm_crtc.h index 8b48a1974da3..37a879350b4e 100644 --- a/include/drm/drm_crtc.h +++ b/include/drm/drm_crtc.h @@ -317,6 +317,16 @@ struct drm_crtc_state { */ enum drm_scaling_filter scaling_filter; + /** + * @sharpness_strength + * + * Used by the user to set the sharpness intensity. + * The value ranges from 0-255. + * Any value greater than 0 means enabling the featuring + * along with setting the value for sharpness. + */ + u8 sharpness_strength; + /** * @event: * @@ -1088,6 +1098,12 @@ struct drm_crtc { */ struct drm_property *scaling_filter_property; + /** + * @sharpness_strength_prop: property to apply + * the intensity of the sharpness requested. + */ + struct drm_property *sharpness_strength_property; + /** * @state: * @@ -1324,4 +1340,5 @@ static inline struct drm_crtc *drm_crtc_find(struct drm_device *dev, int drm_crtc_create_scaling_filter_property(struct drm_crtc *crtc, unsigned int supported_filters); +int drm_crtc_create_sharpness_strength_property(struct drm_crtc *crtc); #endif /* __DRM_CRTC_H__ */
