Solve three memory leaks related to PatchCache A Patch can be fairly large, holding bitmap data, but is also frequently leaked which adds to the severity. The feature is used in many important processes such as Home, SystemUI and Chrome. The following leaks are solved: 1. The Patch itself was not always freed. PatchCache::removeDeferred() can mark patches to be cared for by PatchCache::clearGarbage(). But mCache.remove() would only destroy the container and the pointer, not the Patch object itself. 2. The vertices stored in the Patch at Patch::createMesh() would always leak. The empty/default destructor in Patch would not properly destroy "vertices" since it's just a pointer. 3. A BufferBlock that's added to the mFreeBlocks in PatchCache could leak. The leak happened when a patch later needed the entire free block, because the object was removed from the list but never deleted in PatchCache::setupMesh().

Fix graphics corruption caused by HWUI caches Some caches(PatchCache, TextureCache, PathCache) for HWUI uses deferred removal for their cache entries even though actual resource objects are immediately freed by ResourceCache. For this reason, the uniqueness of a resource address in the caches is not guaranteed in specific cases. (Because malloc() can return the same address when malloc() and free() called very frequently.) So it can be possible the cache have two cache entries for two different resources but the same memory address. (Of course one of the resources is already freed.) It also can be possible mGarbage vector in PatchCache has duplicated addresses and this can lead to duplicated free blocks in the free block list and graphics corruption. (Deferred removal was implmeneted based on an assumption of unique resource addresses.) So this patch makes sure resource objects are freed after the resources are removed from the caches to guarantee the uniqueness of a resource address and prevent graphics corruption.

Refcount 9-patches and properly handle GC events This change adds refcounting of Res_png_9patch instances, the native data structure used to represent 9-patches. The Dalvik NinePatch class now holds a native pointer instead of a Dalvik byte[]. This pointer is used whenever we need to draw the 9-patch (software or hardware.) Since we are now tracking garbage collection of NinePatch objects libhwui's PatchCache must keep a list of free blocks in the VBO used to store the meshes. This change also removes unnecessary instances tracking from GLES20DisplayList. Bitmaps and 9-patches are refcounted at the native level and do not need to be tracked by the Dalvik layer.

Pack preloaded framework assets in a texture atlas 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
