* Support RGBA fonts and bitmap fonts (and RGBA bitmap fonts)Victoria Lease2013-07-311-6/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Share Caches' index buffer with FontRendererRomain Guy2013-06-181-5/+0
| | | | | | | | | This reduces state changes when we draw 9patches and text together, which happens *a lot*. Also disable the NV profiling extension by default since it doesn't play nice with display lists deferrals. To enable it set debug.hwui.nv_profiling to true.

|\ | | | | | | | | * commit '55b883b0a960b37aa453253f3ccb614dd95c221c': Draw Operation merging
| * Draw Operation mergingChris Craik2013-04-151-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge simple bitmap draw operations and text operations to avoid issuing individual gl draws for each operation. Merging other ops to be done eventually. The methods are different - the bitmap merging generates a single mesh for reused, unclipped images (esp. repeated images in a listview) The text approach queries just defers the normal font rendering until the last drawText in the sequence that can share the same shader. Patches are sorted and merged, but don't yet have a multiDraw implementation. For now, the pretending-to-merge gives better sorting behavior by keeping similar patches together.

| * Introduce PixelBuffer API to enable PBOsRomain Guy2013-04-111-10/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Morrill2013-04-041-0/+4
|/ | | | | | | | | | 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

* Reduce number of glDraw calls when drawing textRomain Guy2013-03-191-33/+0
| | | | | | | | This change moves the mesh buffer from FontRenderer to CacheTexture to help reduce the number of texture binds and glDraw calls when drawing text that spans across multiple textures. Change-Id: I7de574d88313ca3672879ca878c253ff5f131fc1
* Minimize texture binds when drawing textRomain Guy2013-03-191-3/+27
| | | | | | | | | | | When several CacheTextures are used to draw text, sort the draw batches by texture ID to minimize state changes in the driver. This change also tweaks the font cache size and renames a property that was too long to be set using setprop. Change-Id: I0a36dfffe58c9e75dd7384592d3343c192d042b1

* Another optimization of glyph cache uploadsSangkyu Lee2012-11-281-1/+6
| | | | | | | | | | | | Previously, cache textures were updated whenever mCurrentCacheTexuture was changed. Since updating cache textures needs glTexSubImage2D call, frequent changing of mCurrentCacheTexture (which can easily happen when an app uses lots of unique glyphs even with precaching) caused many glTexSubImage2D calls and bad framerates. This patch optimized isssueDrawCommand function. Consequently, changing mCurrentCacheTexture doesn't cause glTexSubImage2D call any more and it will improve font rendering performance.

* Avoid thrashing the glyph cache during the precache phaseChet Haase2012-08-301-4/+5
| | | | | | | | | | | | | | | | | | | It is unlikely, but possible, to draw so many glyphs in a frame (especially of the glyphs are quite large) that the cache starts flushing itself to fit the later glyphs in. This causes unnecessary thrashing, because when we actually draw the frame, we will again need to flush to fit the earlier glyphs in, and then flush again to fit the later ones in. It is better to avoid thrashing the cache at the precache phase, and wait until we actually draw the glyphs that do not fit to do any eviction of the earlier glyphs. This change simply notes when we are in the preaching phase, and avoids flushing the cache when a glyph does not fit.

* Remove CacheTextureLine structure from FontRendererChet Haase2012-08-161-58/+30
| | | | | | | | | | | | | | | | | CacheTextureLine was useful before we were packing the glyph textures; it allowed simple packing of any particular texture according to how many lines there were in a texture, and how tall those lines were. Now that we are packing more efficiently (both horizontally and vertically in any given texture line), it is more efficient to have open space in every texture, removing the need for CacheTextureLine (which now gets in the way since it limits how much can be stored in each line). This change removes CacheTextureLine and just uses CacheTexture directly, allowing caching of glyphs anywhere in the open space of each texture. As before, the packing of these glyphs is determined by the CacheBlock structure, which is a linked list of open spaces in each CacheTexture. Change-Id: Id6f628170df0f676f8743ac7de76f2377fc6a012
* Optimize interactions with glyph cacheChet Haase2012-08-141-6/+74
| | | | | | | | | | | | | | | | | There are two fixes here: - precaching: instead of caching-then-drawing whenever there is a new glyph, we cache at DisplayList record time. Then when we finally draw that DisplayList, we just upload the affected texture(s) once, instead of once per change. This is a huge savings in upload time, especially when there are larger glyphs being used by the app. - packing: Previously, glyphs would line up horizontally on each cache line, leaving potentially tons of space vertically, especially when smaller glyphs got put into cache lines intended for large glyphs (which can happen when an app uses lots of unique glyphs, a common case with, for example, chinese/japanese/korean languages). The new approach packs glyphs vertically as well as horizontally to use the space more efficiently and provide space for more glyphs in these situations.

| * Add drop shadow for drawPosText in hwui renderer.Raph Levien2012-07-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for drop shadows (setShadowLayer) for drawPosText in the hwui renderer. In and of itself, it's not very important, but it's on the critical path for correct mark positioning, tracked as bug 5443796. The change itself is fairly straightforward - it basically just adds an extra "positions" argument to all draw and measure methods on the code path for drawing drop shadowed text, as well as to the cache key for cached shadow textures.

* Forget the name of a texture after freeingRomain Guy2012-05-141-2/+2
| | | | | | | | | | | | | | | | | Bug #6408362 FontRenderer allocates large font textures when more room is needed to store all the glyphs used by an application. Thse large textures are the first to be freed when memory needs to be reclaimed by the system. When freeing a texture, the renderer would however not set the texture name to an invalid name, leading future allocations to be performed on the same texture name. That name could have by then be recycled by the driver and returned by a call to glGenTexture and used to create an entirely different texture. This would cause the font renderer to point to the wrong texture, thus leading to the "corruptions." Change-Id: I8a1e80e5b79e8f21d1baf5320c090df4f2066cd4

* De-allocate caches for large glyphs when trimming memoryChet Haase2011-12-161-1/+3
| | | | | | | | | | | | | Currently, font renderers eliminate some texture caches when memory is trimmed. This change makes it go further by eliminating the large-glyph caches for all font renderers. These caches are only allocated as needed, but continue to consume large amounts of memory (CPU and GPU) after that allocation. De-allocating this memory on a trim operation should prevent background apps from holding onto this memory in the possible case that they have allocated it by drawing large glyphs.

* Fix issues from recent glyph caching changeChet Haase2011-12-151-4/+6
| | | | | | | | | | | | | There were 2 issues remaining after a recent change to support glyph caching from multiple textures: - memory in the GPU for all textures was being allocated automatically. This is now lazy, being allocated only when those textures are first needed. - filtering (applied when a rendered object is transformed) was ignoring the new multiple-texture structure. Filtering should be applied correctly whenever we change textures. Change-Id: I5c8eb8d46c73cd01782a353fc79b11cacc2146ab
