* HWC 1.5: Add per-layer damage regionDan Stoza2015-02-251-3/+24
| | | | | | | | | | | This adds an array of rects to hwc_layer_1_t that define which portions of that layer's source buffer have been modified. If there are a non-zero number of rects, then any portion of the source buffer not touched by one of the rects may safely be assumed to not have been modified. If no rects are defined, then the whole source buffer must be assumed to have been modified. Change-Id: Id5efafee74602ed7d76609180e334ed203c23f7e

* hwcomposer: Allow display configuration selectionDan Stoza2014-07-141-11/+54
| | | | | | | | | Adds two functions to the HWC interface: one for querying the current display configuration, and one for setting a new configuration. This will enable DisplayManager to change the mode on demand. Bug: 14320401 Change-Id: I556c509192b877b38b2103a78f937b3687f35546

| * hwcomposer: Add function pointer for setPowerMode() callbackPrashant Malani2014-06-121-12/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The blank HWC call is being replaced by a setPowerMode() call. This incorporates all of the blank functionality, but provides added support for display low power modes, if they are available in hardware. Currently there are three supported modes: - HWC_POWER_MODE_OFF : Turn screen off. - HWC_POWER_MODE_DOZE : Put screen in low power mode. - HWC_POWER_MODE_NORMAL : Turn screen on, and exit low power mode (if display was previously in low power mode). Where applicable, the device driver is expected to retain and restore the low power mode state of the display during entry and exit from suspend, respectively.

* | hwcomposer: Correct padding for 32/64-bitDan Stoza2014-06-041-3/+12
|/ | | | | | | | | The size of hwc_layer_1_t varies depending on whether we're building for a 32- or 64-bit target. This change splits the padding into two sections so that we can add more fields without changing the overall size on either bitness. Change-Id: Ib7c960a9feb0061586dc6398211d7d3dc012d573
* Described restrictions for common HAL object methods.Stewart Miles2014-05-121-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inheritance of HAL object is performed by composing a child structure of a single parent structure located at offset 0 followed by new data members and function pointers in the child structure. For example, struct child { struct parent common; int a_data_member; void (*a_method)(struct child *c, int v); }; HAL code assumes this layout when accessing child structures given a pointer to a parent structure such that users write code like the following... void child_method(struct *parent, int v) { struct child * c = (struct child*)parent; // do stuff with c } Code above will break if a member is added before "common" in "struct child". This change adds comments that describe the restriction on the location of parent HAL objects within a derived HAL object. HAL objects that already have comments that describe the required location of parent objects are not modified. Change-Id: Ibe4300275286ef275b2097534c84f1029d761d87

| | | | | | | | Ensure none of the HAL structs change size over time. Issues might arise when making changes without taking the different pointer sizes for specific architectures into account. Change-Id: I63f00004a23f09b2f46df01e7c69296766a5d03f

* Add HWC_DISPLAY_VIRTUAL and adjust display count constantsJesse Hall2013-08-161-10/+10
| | | | | | | | Both surfaceflinger and HWC implementations have been defining these themselves, making future changes more difficult. Better to define them centrally, where they can be updated easily. Change-Id: I793158b858c84b2470b05f9ea77cc5a0c7e247f1

* Simplify and clean up legacy decisionsJesse Hall2012-08-221-59/+47
| | | | | | | | | | | | | | | | | | | | During the HWC 0.x evolution, some fields were left optional or organized strangely to avoid breaking backwards compatibility. Since we're breaking it in the transition to HWC 1.0 anyway, we can clean these up a little. * The current callbacks are now registered immediately after the device is opened and guaranteed to be present, so the implementation can rely on them being present. * The hwc_methods_t structure is gone, with its two methods folded into the main hwc_composer_device_1_t. * All methods and callbacks are now required except dump(). New methods and callbacks we add in the future will still be optional for backwards compatibility. Change-Id: I5d58774a5144016993c12df3dd6ad2a5d746bee9

* Simplify prepare and set semantics (comments only)Jesse Hall2012-08-071-16/+12
| | | | | | | | | | | | | | | Documentation updated for semantic changes vs. HWC 0.x: * Prepare won't be called with NULL pointers. This used to be used to disable hardware composition, though that wasn't documented. Now we'll call prepare with non-NULL pointers but the layer list will have zero layers. * Set won't be called with NULL pointers. This used to cause the display to turn off; that is now done by calling the blank() method, which is no longer optional. Change-Id: I9c69dc34f64e499a5ba5f8729836e7c216f8c733

* split hwcomposer.hMathias Agopian2012-05-131-112/+2
| | | | | | | | | | | | hwcomposer_defs.h now contains enums, which are essentially names. This won't change when we rev the h/w composer API (new ones will be added instead). we do this to avoid having to abstract all these constants in higher level APIs; instead hwcomposer_defs.h can be included without exposing the hwcomposer's data structures (which are a lot more fragile wrt. backward compatibility) Change-Id: Ifb514f64de02a599fdd2d31c188327209ccb0ffc
