* gralloc: Sort usage flagsDan Stoza2015-06-031-17/+16
| | | | | | | | Sorts the usage flags in increasing order so it's easier to see where the gaps are. Bug: 21609491 Change-Id: I98af3c67be84c6c5137767f3cd7a8bd63dfb5c03

* gralloc: Add foreign buffer usage flagDan Stoza2015-05-291-0/+11
| | | | | | | | | | | | | | | | | Adds GRALLOC_USAGE_FOREIGN_BUFFERS, which a consumer may set as a usage flag if it intends to attach buffers that it has not detached from the BufferQueue. It provides a hint to the producer (who may query the consumer usage bits) that it may receive a buffer from another BufferQueue, so that it can exit during initialization, hopefully with a meaningful error message, if such buffers are not supported. Also adds GRALLOC_USAGE_ALLOC_MASK, which is applied to usage bits before calling alloc on the gralloc module, and prevents the module from seeing GRALLOC_USAGE_FOREIGN_BUFFERS, since that usage flag is of no use while allocating buffers.

* gralloc: add GRALLOC_USAGE_CURSOR flagGreg Hackmann2014-07-231-0/+3
| | | | | | | | | | | | | | On many devices, hardware cursors have stricter layout constraints than other overlays. GRALLOC_USAGE_CURSOR indicates a buffer may be used as a cursor; byte order and padding should be chosen accordingly. GRALLOC_USAGE_CURSOR must not cause allocation failure. If the requested properties (dimensions, format, other usage flags, etc.) aren't compatible with the device's cursor hardware, the implementation must allocate the buffer anyway, acting as if GRALLOC_USAGE_CURSOR were not specified.

* gralloc: Add asynchronous lock/unlock APIFrancis Hart2014-05-121-1/+50
| | | | | | | | | | | The existing API exposed to clients for software lock/unlock forces the gralloc implementation to complete these operations synchronously. This change adds new entry points for lock/unlock functionality that is suited for use with Android's explicit synchronisation concept. This provides scope for the gralloc module to internally optimise the work it must do for lock/unlock and to hide this cost from the client. Change-Id: If4b1bb5490ab2b20d796214a7da8a96427cfe52d

* Add reprocess method, redefine gralloc ZSL usage flagEino-Ville Talvala2012-09-011-1/+3
| | | | | | | | | - Camera2: Add allocate_reprocess_stream_from_stream for ZSL usecases - Gralloc: Make GRALLOC_USAGE_HW_CAMERA_ZSL be simply GRALLOC_USAGE_HW_CAMERA_READ | GRALLOC_USAGE_HW_CAMERA_WRITE - Gralloc: Add GRALLOC_USAGE_HW_CAMERA_MASK Change-Id: Icd8ac1f786e3adb6a422f27f03a5a4cb04a815cc
* Camera2: Use HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINEDEino-Ville Talvala2012-08-281-0/+2
| | | | | | | | | | | | | | | | | | Align camera2's management of platform-opaque formats with rest of framework. Instead of using CAMERA2_PIXEL_FORMAT_OPAQUE, use HAL_PIXEL_FORMAT_IMPLEMENTATION_DEFINED as the format for both the camera HAL and for gralloc, and depend on the gralloc usage flags to let the gralloc module select the appropriate real format for specific stream endpoints. Add a new gralloc usage for ZSL mode, where the camera service will hold a streaming circular buffer of opaque full-resolution images during camera preview. Since this is an opaque format that needs to be optimized for 30fps operation, need gralloc to be aware of this use case. Bug: 6243944 Change-Id: If7f2516649381ce9bcffe4e319b63cbc068f643f
* Add camera gralloc usage flags.Eino-Ville Talvala2012-07-161-1/+5
| | | | | | | | | | | GRALLOC_USAGE_HW_CAMERA_WRITE is for camera outputs in the new camera HAL. GRALLOC_USAGE_HW_CAMERA_READ is for sending previously captured camera data back into the camera pipeline for further processing. For example, for converting a raw sensor image into YUV or JPEG data.

* fix[2222341] Soft reset while going back from camcorder settingsMathias Agopian2009-10-301-2/+14
| | | | | add a way to convert a mapped "pushbuffer" buffer to a gralloc handle which then can be safely used by surfaceflinger
* Android side of the fix for [2121211] Sholes has stutter during animationsMathias Agopian2009-09-171-1/+12
| | | | a new method, compostionComplete() is added to the framebuffer hal, it is used by surfaceflinger to signal the driver that the composition is complete, BEFORE it releases its client. This gives a chance to the driver to perfrom the proper synchronization.

* lock will now return the vaddr of the buffer. map/umap are gone.Mathias Agopian2009-05-041-23/+39
| | | | | | - make sure to return an error if a buffer is locked twice or unlocked while not locked. - added registerBuffer() and unregisterBuffer() to the gralloc module so that we can do some cleanup when a buffer is no longer needed. this became necessary after we removed map/unmap so we have a place to unmap buffers without the need of a kernel module. - change the constants for GRALLOC_USAGE_SW_{READ|WRITE}_NEVER to 0, so that NOT specifying them means "NEVER".
* Integrate from //sandbox/mathias/donut/...@145728Mathias Agopian2009-04-101-0/+284
SurfaceFlinger rework for new EGL driver model support.
