struct wlr_dmabuf_v1_buffer ¶
struct wlr_dmabuf_v1_buffer { struct wlr_buffer base; struct wl_resource *resource; struct wlr_dmabuf_attributes attributes; struct wl_listener release; };
wlr_dmabuf_v1_buffer_from_buffer_resource() ¶
struct wlr_dmabuf_v1_buffer *wlr_dmabuf_v1_buffer_from_buffer_resource(struct wl_resource *buffer_resource);
Returns the struct wlr_dmabuf_buffer if the given resource was created via the linux-dmabuf buffer protocol.
wlr_dmabuf_v1_resource_is_buffer() ¶
bool wlr_dmabuf_v1_resource_is_buffer(struct wl_resource *buffer_resource);
Returns true if the given resource was created via the linux-dmabuf buffer protocol, false otherwise
struct wlr_linux_dmabuf_feedback_v1 ¶
struct wlr_linux_dmabuf_feedback_v1 { dev_t main_device; size_t tranches_len; const struct wlr_linux_dmabuf_feedback_v1_tranche *tranches; };
struct wlr_linux_dmabuf_feedback_v1_tranche ¶
struct wlr_linux_dmabuf_feedback_v1_tranche { dev_t target_device; uint32_t flags; const struct wlr_drm_format_set *formats; };
struct wlr_linux_dmabuf_v1 ¶
struct wlr_linux_dmabuf_v1 { struct wl_global *global; struct wlr_renderer *renderer; struct { struct wl_signal destroy; } events; struct wlr_linux_dmabuf_feedback_v1_compiled *default_feedback; struct wl_list surfaces; struct wl_listener display_destroy; struct wl_listener renderer_destroy; };
the protocol interface
wlr_linux_dmabuf_v1_create() ¶
struct wlr_linux_dmabuf_v1 *wlr_linux_dmabuf_v1_create(struct wl_display *display, struct wlr_renderer *renderer);
Create linux-dmabuf interface.
wlr_linux_dmabuf_v1_set_surface_feedback() ¶
bool wlr_linux_dmabuf_v1_set_surface_feedback(struct wlr_linux_dmabuf_v1 *linux_dmabuf, struct wlr_surface *surface, const struct wlr_linux_dmabuf_feedback_v1 *feedback);
Set a surface's DMA-BUF feedback.
Passing a NULL feedback resets it to the default feedback.
