* Pack preloaded framework assets in a texture atlasRomain Guy2013-05-021-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the Android runtime starts, the system preloads a series of assets in the Zygote process. These assets are shared across all processes. Unfortunately, each one of these assets is later uploaded in its own OpenGL texture, once per process. This wastes memory and generates unnecessary OpenGL state changes. This CL introduces an asset server that provides an atlas to all processes. Note: bitmaps used by skia shaders are *not* sampled from the atlas. It's an uncommon use case and would require extra texture transforms in the GL shaders. WHAT IS THE ASSETS ATLAS The "assets atlas" is a single, shareable graphic buffer that contains all the system's preloaded bitmap drawables (this includes 9-patches.) The atlas is made of two distinct objects: the graphic buffer that contains the actual pixels and the map which indicates where each preloaded bitmap can be found in the atlas (essentially a pair of x and y coordinates.) HOW IS THE ASSETS ATLAS GENERATED Because we need to support a wide variety of devices and because it is easy to change the list of preloaded drawables, the atlas is generated at runtime, during the startup phase of the system process. There are several steps that lead to the atlas generation: 1. If the device is booting for the first time, or if the device was updated, we need to find the best atlas configuration. To do so, the atlas service tries a number of width, height and algorithm variations that allows us to pack as many assets as possible while using as little memory as possible. Once a best configuration is found, it gets written to disk in /data/system/framework_atlas 2. Given a best configuration (algorithm variant, dimensions and number of bitmaps that can be packed in the atlas), the atlas service packs all the preloaded bitmaps into a single graphic buffer object. 3. The packing is done using Skia in a temporary native bitmap. The Skia bitmap is then copied into the graphic buffer using OpenGL ES to benefit from texture swizzling. HOW PROCESSES USE THE ATLAS Whenever a process' hardware renderer initializes its EGL context, it queries the atlas service for the graphic buffer and the map. It is important to remember that both the context and the map will be valid for the lifetime of the hardware renderer (if the system process goes down, all apps get killed as well.) Every time the hardware renderer needs to render a bitmap, it first checks whether the bitmap can be found in the assets atlas. When the bitmap is part of the atlas, texture coordinates are remapped appropriately before rendering. Change-Id: I8eaecf53e7f6a33d90da3d0047c5ceec89ea3af0

| * Introduce PixelBuffer API to enable PBOsRomain Guy2013-04-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform asynchronous texture uploads to free up the CPU. This change does not enable the use of PBOs unless a specific property is set (Adreno drivers have issues with PBOs at the moment, Mali drivers work just fine.) This change also cleans up Font/FontRenderer a little bit and improves performance of drop shadows generations by using memcpy() instead of a manual byte-by-byte copy. On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance behaves like a simple byte array. The extra APIs introduced for PBOs (map/unmap and bind/unbind) are pretty much no-ops for CPU pixel buffers and won't introduce any significant overhead. This change also fixes a bug with text drop shadows: if the drop shadow is larger than the max texture size, the renderer would leave the GL context in a bad state and generate 0x501 errors. This change simply skips drop shadows if they are too large. Change-Id: I2700aadb0c6093431dc5dee3d587d689190c4e23

* | Phase 1 of refactoring SystemServer.Dan Morrill2013-04-041-5/+11
|/ | | | | | | | | | SystemServer is currently a monolithic class that brings up key system services. This change is the first phase of refactoring it to be more configurable. Specifically, it adds a set of on/off switches used to control startup of individual services. Future plans include finer grained controls and a more explicit and consistent startup sequence for these services. Change-Id: I7299f5ce7d7b74a34eb56dffb788366fbc058532

* Add TaskManager APIRomain Guy2013-03-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This API can be used to run arbitrary tasks on a pool of worker threads. The number of threads is calculated based on the number of CPU cores available. The API is made of 3 classes: TaskManager Creates and manages the worker threads. Task Describes the work to be done and the type of the output. A task contains a future used to wait for the worker thread to be done computing the result of the task. TaskProcessor The processor dispatches tasks to the TaskManager and is responsible for performing the computation required by each task. A processor will only be asked to process tasks sent to the manager through the processor. A typical use case: class MyTask: Task<MyType> class MyProcessor: TaskProcessor<MyType> TaskManager m = new TaskManager(); MyProcessor p = new MyProcessor(m); MyTask t = new MyTask(); p.add(t); // Waits until the result is available MyType result = t->getResult(); Change-Id: I1fe845ba4c49bb0e1b0627ab147f9a861c8e0749

Eventually, multiple complete canvas draw operations will be merged (into a single glDrawArrays call, for example) Reorders DisplayList draw operations when: -They can move backwards in the command stream to be after similar operations without violating draw ordering -The OpenGLRenderer is in a simple, replayable state (no complex clip, or filter/shadow etc) Also adds two system properties to control the deferral/reordering: "debug.hwui.disable_draw_defer" "debug.hwui.disable_draw_reorder" which can be set to "true" to control the display list manipulation Change-Id: I5e89f3cb0ea2d2afd3e15c64d7f32b8406777a32

| * Add a RenderBuffer object to store stencil buffers.Romain Guy2013-02-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug #7146141 This change is needed to add a render buffer cache to avoid creating and destroying stencil buffers on every frame. This change also allows the renderer to use a 1 bit or 4 bit stencil buffer whenever possible. Finally this change fixes a bug introduced by a previous CL which causes the stencil buffer to not be updated in certain conditions. The fix relies on a new optional parameter in drawColorRects() that can be used to avoid performing a quickReject on rectangles generated by the clip region.

* Enable changing properties of layer paintChet Haase2012-09-071-0/+1
| | | | | | | | | | | | Previously, to draw a layered view with a changed Paint object for the drawLayer operation, you'd have to invalidate the parent view, to get the native DisplayList to pick up the new Paint properties. This change adds API and functionality so that the developer can call setLayerPaint(), which does the proper invalidation (lightweight, doesn't cause redrawing the view).
