(Naveen/Chaitanya) v7: Retain the unsupported modifiers, userspace should have no impact, return pointer to blob instead of blob_id(Ville) Signed-off-by: Arun R Murthy Reviewed-by: Chaitanya Kumar Borah Tested-by: Naveen Kumar Reviewed-by: Ville Syrjälä --- drivers/gpu/drm/drm_plane.c | 44 +++++++++++++++++++++++++++++++------------- 1 file changed, 31 insertions(+), 13 deletions(-) diff --git a/drivers/gpu/drm/drm_plane.c b/drivers/gpu/drm/drm_plane.c index fe181c1002171acc68d3054c2d178f9b9f501fe2..5cd3956caf414fa72432f9d23fa289ec266408ce 100644 --- a/drivers/gpu/drm/drm_plane.c +++ b/drivers/gpu/drm/drm_plane.c @@ -193,9 +193,13 @@ modifiers_ptr(struct drm_format_modifier_blob *blob) return (struct drm_format_modifier *)(((char *)blob) + blob->modifiers_offset); } -static int create_in_format_blob(struct drm_device *dev, struct drm_plane *plane) +static struct drm_property_blob *create_in_format_blob(struct drm_device *dev, + struct drm_plane *plane, + bool (*format_mod_supported) + (struct drm_plane *plane, + u32 format, + u64 modifier)) { - const struct drm_mode_config *config = &dev->mode_config; struct drm_property_blob *blob; struct drm_format_modifier *mod; size_t blob_size, formats_size, modifiers_size; @@ -221,7 +225,7 @@ static int create_in_format_blob(struct drm_device *dev, struct drm_plane *plane blob = drm_property_create_blob(dev, blob_size, NULL); if (IS_ERR(blob)) - return -1; + return PTR_ERR(blob); blob_data = blob->data; blob_data->version = FORMAT_BLOB_CURRENT; @@ -237,10 +241,10 @@ static int create_in_format_blob(struct drm_device *dev, struct drm_plane *plane mod = modifiers_ptr(blob_data); for (i = 0; i < plane->modifier_count; i++) { for (j = 0; j < plane->format_count; j++) { - if (!plane->funcs->format_mod_supported || - plane->funcs->format_mod_supported(plane, - plane->format_types[j], - plane->modifiers[i])) { + if (!format_mod_supported || + format_mod_supported(plane, + plane->format_types[j], + plane->modifiers[i])) { mod->formats |= 1ULL << j; } } @@ -251,10 +255,7 @@ static int create_in_format_blob(struct drm_device *dev, struct drm_plane *plane mod++; } - drm_object_attach_property(&plane->base, config->modifiers_property, - blob->base.id); - - return 0; + return blob; } /** @@ -366,6 +367,7 @@ static int __drm_universal_plane_init(struct drm_device *dev, const char *name, va_list ap) { struct drm_mode_config *config = &dev->mode_config; + struct drm_property_blob *blob; static const uint64_t default_modifiers[] = { DRM_FORMAT_MOD_LINEAR, }; @@ -477,8 +479,24 @@ static int __drm_universal_plane_init(struct drm_device *dev, drm_plane_create_hotspot_properties(plane); } - if (format_modifier_count) - create_in_format_blob(dev, plane); + if (format_modifier_count) { + blob = create_in_format_blob(dev, plane, + plane->funcs->format_mod_supported); + if (!IS_ERR(blob)) + drm_object_attach_property(&plane->base, + config->modifiers_property, + blob->base.id); + } + + if (plane->funcs->format_mod_supported_async) { + blob = create_in_format_blob(dev, plane, + plane->funcs->format_mod_supported_async); + if (!IS_ERR(blob)) + drm_object_attach_property(&plane->base, + config->async_modifiers_property, + blob->base.id); + } + return 0; }
