From 59e71ee746a37fe077b73cecf189de1d27efd6eb Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 29 Aug 2016 10:27:55 +0200 Subject: drm: Extract drm_property.[hc] This just contains the base property classes and all the code to handle blobs. I think for any kind of standardized/shared properties it's better to have separate files - this is fairly big already as-is. v2: resurrect misplaced hunk (Daniel Stone) Cc: Daniel Stone Reviewed-by: Archit Taneja Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20160829082757.17913-7-daniel.vetter@ffwll.ch --- include/drm/drm_crtc.h | 88 +-------------------------------- include/drm/drm_property.h | 120 +++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 121 insertions(+), 87 deletions(-) create mode 100644 include/drm/drm_property.h (limited to 'include/drm') diff --git a/include/drm/drm_crtc.h b/include/drm/drm_crtc.h index 63f03490e987..3d33c90da9e5 100644 --- a/include/drm/drm_crtc.h +++ b/include/drm/drm_crtc.h @@ -41,6 +41,7 @@ #include #include #include +#include struct drm_device; struct drm_mode_set; @@ -82,33 +83,6 @@ struct drm_tile_group { u8 group_data[8]; }; -struct drm_property_blob { - struct drm_mode_object base; - struct drm_device *dev; - struct list_head head_global; - struct list_head head_file; - size_t length; - unsigned char data[]; -}; - -struct drm_property_enum { - uint64_t value; - struct list_head head; - char name[DRM_PROP_NAME_LEN]; -}; - -struct drm_property { - struct list_head head; - struct drm_mode_object base; - uint32_t flags; - char name[DRM_PROP_NAME_LEN]; - uint32_t num_values; - uint64_t *values; - struct drm_device *dev; - - struct list_head enum_list; -}; - struct drm_crtc; struct drm_encoder; struct drm_pending_vblank_event; @@ -2026,15 +2000,9 @@ struct drm_mode_config { #define obj_to_crtc(x) container_of(x, struct drm_crtc, base) #define obj_to_mode(x) container_of(x, struct drm_display_mode, base) #define obj_to_fb(x) container_of(x, struct drm_framebuffer, base) -#define obj_to_property(x) container_of(x, struct drm_property, base) #define obj_to_blob(x) container_of(x, struct drm_property_blob, base) #define obj_to_plane(x) container_of(x, struct drm_plane, base) -struct drm_prop_enum_list { - int type; - char *name; -}; - extern __printf(6, 7) int drm_crtc_init_with_planes(struct drm_device *dev, struct drm_crtc *crtc, @@ -2107,52 +2075,6 @@ extern void drm_mode_config_init(struct drm_device *dev); extern void drm_mode_config_reset(struct drm_device *dev); extern void drm_mode_config_cleanup(struct drm_device *dev); -static inline bool drm_property_type_is(struct drm_property *property, - uint32_t type) -{ - /* instanceof for props.. handles extended type vs original types: */ - if (property->flags & DRM_MODE_PROP_EXTENDED_TYPE) - return (property->flags & DRM_MODE_PROP_EXTENDED_TYPE) == type; - return property->flags & type; -} - -extern struct drm_property *drm_property_create(struct drm_device *dev, int flags, - const char *name, int num_values); -extern struct drm_property *drm_property_create_enum(struct drm_device *dev, int flags, - const char *name, - const struct drm_prop_enum_list *props, - int num_values); -struct drm_property *drm_property_create_bitmask(struct drm_device *dev, - int flags, const char *name, - const struct drm_prop_enum_list *props, - int num_props, - uint64_t supported_bits); -struct drm_property *drm_property_create_range(struct drm_device *dev, int flags, - const char *name, - uint64_t min, uint64_t max); -struct drm_property *drm_property_create_signed_range(struct drm_device *dev, - int flags, const char *name, - int64_t min, int64_t max); -struct drm_property *drm_property_create_object(struct drm_device *dev, - int flags, const char *name, uint32_t type); -struct drm_property *drm_property_create_bool(struct drm_device *dev, int flags, - const char *name); -struct drm_property_blob *drm_property_create_blob(struct drm_device *dev, - size_t length, - const void *data); -struct drm_property_blob *drm_property_lookup_blob(struct drm_device *dev, - uint32_t id); -int drm_property_replace_global_blob(struct drm_device *dev, - struct drm_property_blob **replace, - size_t length, - const void *data, - struct drm_mode_object *obj_holds_id, - struct drm_property *prop_holds_id); -struct drm_property_blob *drm_property_reference_blob(struct drm_property_blob *blob); -void drm_property_unreference_blob(struct drm_property_blob *blob); -extern void drm_property_destroy(struct drm_device *dev, struct drm_property *property); -extern int drm_property_add_enum(struct drm_property *property, int index, - uint64_t value, const char *name); extern int drm_mode_crtc_set_gamma_size(struct drm_crtc *crtc, int gamma_size); @@ -2202,14 +2124,6 @@ static inline struct drm_crtc *drm_crtc_find(struct drm_device *dev, return mo ?
