Bug: 22676664

If a task is queued on a worker thread that is busy
processing a task AND a trim memory signal comes along
prior to the initial task being completed then the
tasks that were queued prior to the exit request will
never be processed.

This is bad, as when those futures are used later on, such
as in trying to delete them from the cache, they will block
waiting for the orphaned task to be finished.

Simple fix is to just never stop the worker threads. Increase
RAM usage slightly as we won't reclaim that stack space, but
this cost is fairly small

ebd52610cfeff6e557fde284a7e1efc5e6438285 11-Dec-2014 John Reck <jreck@google.com> Don't preload textures for AssetAtlas

Bug: 18317479

RenderNode::prepareSubTree calls prefetchAndMarkInUse
on every bitmapResoruce in the DisplayList. However,
this resulted in textures being uploaded for bitmaps
that would be drawn from the AssetAtlas instead.

To fix this we teach TextureCache about the AssetAtlas
so that calls to TextureCache return the Texture from
AssetAtlas if it exists. Thus usage of AssetAtlas
is now purely to allow for further optimizations via
draw merging instead of a requirement to get
any benefit at all.

70735bd5ddd6ba3063d5537f510324cb2515aba6 29-Aug-2014 Fred Fettinger <fred.fettinger@motorola.com> hwui: Caches: use mBoundTextures only for GL_TEXTURE_2D

bug:17441218

GLConsumer uses glBindTexture() directly instead of going through
Caches::bindTexture(). This can cause libhwui to draw with the wrong
texture bound in the following case which involves 2 TextureViews:

Frame 1:
GLConsumer::updateTexImage() calls glBindTexture(GL_TEXTURE_EXTERNAL_OES, 1)
HWUI renders TextureView A:
calls Caches::bindTexture(GL_TEXTURE_EXTERNAL_OES, 1) and draws

Frame 2:
GLConsumer::updateTexImage() calls glBindTexture(GL_TEXTURE_EXTERNAL_OES, 1)
GLConsumer::updateTexImage() calls glBindTexture(GL_TEXTURE_EXTERNAL_OES, 2)
HWUI renders TextureView A:
calls Caches::bindTexture(GL_TEXTURE_EXTERNAL_OES, 1) and draws
HWUI renders TextureView B:
calls Caches::bindTexture(GL_TEXTURE_EXTERNAL_OES, 2) and draws

In this case, HWUI will incorrectly draw TextureView A using texture 2 on
frame 2, because mBoundTextures[0]=1, even though the texture currently
bound to GL_TEXTURE_EXTERNAL_OES is 2.

Since GLConsumer is always used with a target of GL_TEXTURE_EXTERNAL_OES,
work around this problem by having mBoundTextures[] store only the
textures bound to the target GL_TEXTURE_2D. This is the common case
where the extra performance is needed. Since it's legal to have
different textures bound to GL_TEXTURE_2D and GL_TEXTURE_EXTERNAL_OES
on one texture unit, Caches::bindTexture() does not need to clear
mBoundTextures[mTextureUnit] when target != GL_TEXTURE_2D.

17035b0211a3c9d45ea46a99217a6acbe76e8fbe 03-Sep-2014 John Reck <jreck@google.com> Have destroy call freePrefetchedLayers

Bug: 17208461

There's a potential race condition between HardwareRenderer.destroy()
being called (which calls destroyCanvasAndSurface()) and the renderer
being finalized (which is what calls freePrefetchedLayers), during which
time it's possible we get a TRIM_MEMORY_COMPLETE and destroy the EGL
context.

Fix this race condition by moving stopDrawing() and freePrefetchedLayers()
into destroyCanvasAndSurface() where they should have been in the first
place.

Also, if we hit the assertion failure, dump the current state of
Caches to try and provide more context for the failure.

Quite a few things going on in this commit:

- Enable bitmap strikes by default in Paint objects.

The SkPaint parameter that enables bitmap strikes was not previously
included in DEFAULT_PAINT_FLAGS. This effectively disabled bitmap
fonts. Oops! It's for the best, though, as additional work was needed
in Skia to make bitmap fonts work anyway.

- Complain if TEXTURE_BORDER_SIZE is not 1.

Our glyph cache code does not currently handle any value other than 1
here, including zero. I've added a little C preprocessor check to
prevent future engineers (including especially future-me) from
thinking that they can change this value without updating the related
code.

- Add GL_RGBA support to hwui's FontRenderer and friends

This also happened to involve some refactoring for convenience and
cleanliness.

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.

3b748a44c6bd2ea05fe16839caf73dbe50bd7ae9 18-Apr-2013 Romain Guy <romainguy@google.com> 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.

cf51a4199835e9604aa4c8b3854306f8fbabbf33 09-Apr-2013 Romain Guy <romainguy@google.com> Introduce PixelBuffer API to enable PBOs

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.

bug:8037003

A recursive drawDisplayList call is now entirely deferred before
playing back to the screen and issuing GL commands. This way, the
entire stream can be inspected, optimized, and batch work (such as
uploading textures) before issuing commands.

Additionally, this fixes an issue where operations draw could move
across restores corresponding to saveLayer(alpha). Those and other
similar cases (such as complex clipping, requiring the stencil) are
now treated as batching barriers, with the operations that change
renderer state in a way that's difficult to defer are just re-issued
at flush time.

6a2d17f71342f981c9df1dc5beff33e30eb3ae2b 30-Sep-2012 Chet Haase <chet@google.com> Fix texture corruption

When memory gets low on a device, activities flush everything they can.
Hardware-accelerated activites, such as Launcher, flush GL resources and destroy
the GL context. However, some resources were still hanging around, due to deferred
destruction policies (we don't delete layers until the DisplayLists they are in
are finalized, to ensure we don't deref deleted objects). This meant that we were
referring to obsolete GL data in these objects. in particular, it meant that we might
come around later, after a new GL context was created, and delete a texture object
that was incorrect. We use the layer's "texture id" to refer to the texture underlying the
layer. But if there's a new GL context, then this texture ID is no longer valid, and
we may be deleting the texture that a different object (layer, icon, whatever) is referring
to, because the driver may return that same ID under the new GL context.

The fix is to more aggressively delete things that we know will not be used again
when the GL context is destroyed. In particular, we delete all resources being used
by all DisplayLists at GL context destruction time.

This change improves execution of display lists, particularly on
tiled renderers. The goal is to disable the scissor test as
often as possible. Drawing commands are rarely clipped by View
bounds so most of them can be drawn without doing a scissor test.

The speed improvements scale with the number of views and drawing
commands.

This change will be beneficial to Launcher to avoid hiccups when

in the layers pool instead of being destroyed right away. This
favors memory reuse over allocations.
