2013-06-12Overdraw avoidance and merging of clipped opsChris Craik
bug:8951267 If an opaque op, or group of opaque ops covers the invalidate region, skip draw operations that precede it. Clipped operations may now be merged, but only if they share a clipRect - this is a very case for e.g. ListView, where all background elements may now be a part of the same MergingDrawBatch. It is this more aggressive merging that groups together clipped background elements in the ListView case, enabling the overdraw avoidance skipping the window background.

2013-05-21Use individual glyph positions to determine text bounds.Chris Craik
bug:8766924 Previously text bounds were calculated to be from 0 to totalAdvance in the X, and from the font's top to bottom. These are incorrect, especially in light of the font fallback mechanism. Now, we calculate the bounds of the text as we layout each glyph. Since these are much tighter bounds in the common case, this significantly reduces the amount of clipping required (which in turn enables more aggressive text merging).

2013-05-09Fix off by one error in log trackingChris Craik
bug:8875715 Additionally moves op logging before the op is executed, to print correctly, in pre-order traversal Change-Id: I4e9566261f8363c73739d183e6d82b854f72ffad
2013-04-15Draw Operation mergingChris Craik
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.

2013-04-11Introduce PixelBuffer API to enable PBOsRomain Guy
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
2013-04-03Correct save/restore match upChris Craik
bug:8480642 With the additional save/restore around the operations in flush, the stored restore batches weren't matching up to the correct saves. Change-Id: I2f48f19009bd97289b6973283f43dc8d3e35affd
2013-03-28Fix issues related to saveLayer/restore deferralChris Craik
bug:8464795 Changes drawModifiers and alpha to be restored for all operations, since saveLayer/restore use these values, not just draw operations Also forces a renderer state restoration before a deferred restore op is played back, in case it is associated with a saveLayer that doesn't have the save_clip flag set Change-Id: I9da5d44fefbfffdee164c98f4f139843dacf85df
2013-03-22Restore final canvas state after deferred flushChris Craik
bug:8450062 - Fixes overdraw indication with DeferredDisplayList - Fixes drawHardwareLayer called after flush Additionally changes drawLayer to pass its paint to native via setLayerPaint Wrap flush in save/restore so that reordering doesn't affect final transform Change-Id: I08befa42c28500da6387699eefd4be28aedf9f4c
2013-03-20Update snapshot upon saveLayer deferralChris Craik
bug:8409891 In order to defer fbo-targetting saveLayer operations, it's necessary to update the snapshot at defer time so that deferred display state (namely, clip and transform) are fbo relative. Re-enables deferring, as the issues with saveLayer are fixed. Change-Id: I74b0779bc732675c747208f0757c3ea85f6dfbed
2013-03-20Merge "Use snapshot alpha for layers" into jb-mr2-devChris Craik
2013-03-18Merge all shapes/paths caches to PathCacheRomain Guy
This change will greatly simplify the multi-threading of all shape types. This change also uses PathTessellator to render convex paths. Change-Id: I4e65bc95c9d24ecae2183b72204de5c2dfb6ada4
2013-03-15Reset draw modifiers after flushingChris Craik
bug:8401910 This avoids leaving the renderer in a state with stale pointers (to, e.g., shaders or color filters) Change-Id: Idf8b63657041352e70e34e91ea416fe4385d4bc2
2013-03-15Use snapshot alpha for layersChris Craik
Removes mMultipliedAlpha, using the snapshot alpha for all non-overlapping display list alpha control. Additionally, fixes opacity issues where children of hasOverlappingRendering=false displaylists (both hw layer sublists and other sublists with hasOverlappingRendering=false) Change-Id: I6adc16da855835f9f518f8967628e5d0135c789b
2013-03-15Fully deferred displaylist replayChris Craik
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.

2013-03-01Precache glyphs at final raster sizeRomain Guy
The deferred display lists model now allows us to precache glyphs at their exact size on screen. This change also removes debug markers when the renderer defers and reorders display lists. It also adds a flush event marker. Change-Id: I66ec5216dc12b93ecfdad52a7146b1cfb31fbeb4
2013-02-15DisplayList draw operation reorderingChris Craik
bug:8037003 The reordering enables similar operations to draw together, minimizing the OpenGL state change operations that go inbetween draws. 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
