The TDM provides functions for managing display server.

Required Header

#include <hal-tdm.h>

Overview

The TDM functions provides an abstraction interface for display server including:

Display server interface to user like getting display capabilities, size, format.
Display control interface like display mode setting, dpms, capture.

For more information on the TDM features and the macros, see HAL TDM programming guides and tutorials.

Possible composition types for the given window.

Since:: HAL_MODULE_TDM 1.0

Enumerator:

HAL_TDM_HWC_WIN_COMPOSITION_NONE	The composition type for an invisible window. The value by default. The backend ignores windows of this type.
HAL_TDM_HWC_WIN_COMPOSITION_CLIENT	The composition type for an window to be compsoited by the client. When the client sets this composition type, the backend MUST NOT modify this composition type into other types. When the backend changes TDM_HWC_WIN_COMPOSITION_DEVICE or TDM_HWC_WIN_COMPOSITION_CURSOR to this composition type at the time of tdm_hwc_validate and tdm_hwc_get_changed_composition_types, the client has to composite this window with gl or other drawing operations.
HAL_TDM_HWC_WIN_COMPOSITION_DEVICE	The composition type for an window to be set to the hw overlay. The client sets this composition type to the visible windows before requesting the tdm_hwc_validate. Nomally, the backend leave it if the backend sets the window to the hw overlay. If the backend does not set the window to the hw overlay at the time of tdm_hwc_validate, the backend changes the composition type of the window into TDM_HWC_WIN_COMPOSITION_CLIENT.
HAL_TDM_HWC_WIN_COMPOSITION_CURSOR	The composition type for an window to be set to the cursor hw overlay. The client sets this composition type to the cursor window before requesting the tdm_hwc_validate. If the backend does not support the cursor hw overlay, the backend can change the comopsition type into the TDM_HWC_WIN_COMPOSITION_CLIENT.
HAL_TDM_HWC_WIN_COMPOSITION_VIDEO	The composition type for an window to be set to the video hw overlay. The client sets this composition type to the video window before requesting the tdm_hwc_validate. If the backend does not support the video hw overlay, the backend can change the comopsition type into the TDM_HWC_WIN_COMPOSITION_CLIENT. Normally, this VIDEO window displays under the primary hw overlayer of the output.

enum hal_tdm_hwc_window_constraint

HWC's composition mode for specific buffer.

Since:: HAL_MODULE_TDM 1.0

Enumerator:

HAL_TDM_HWC_WIN_CONSTRAINT_BUFFER_QUEUE

If the client needs to render to the specific buffer for compositing with TDM_HWC_WIN_COMPOSITION_DEVICE, the backend needs to set TDM_HWC_WIN_CONSTRAINT_BUFFER_QUEUE to hwc_window until the hwc_window is not TDM_HWC_WIN_COMPOSITION_DEVICE. The client gets the tbm_surface_queue_h through the tdm_hwc_window_acquire_buffer_queue. It will render the frames on the buffers which gets from the tbm_surface_queue_h.
