2018-04-12So long OpenGLPipeline & OpenGLReadback (2/??) John Reck
Hello EglReadback Test: hwuiunit & PixelCopyTests pass Change-Id: I36a8cb45b11141b09e75a2e978ed13e336425625
2017-11-03Format the world (or just HWUI) John Reck
Test: No code changes, just ran through clang-format Change-Id: Id23aa4ec7eebc0446fe3a30260f33e7fd455bb8c
2017-11-01Fix PixelCopyTest failure in CTS Romain Guy
This feature needs support for renderable float textures, but the checks were only guaranteeing support for float texture reads. Bug: 68754504 Test: CtsViewTestCases Change-Id: I0ce4a81cb8e09c10a5f1e65234685767a24ef8c4
2017-09-22Merge "Speculative fix for missing target crash" into oc-mr1-dev TreeHugger Robot
2017-09-22Speculative fix for missing target crash Chris Craik
Bug: 66451158 Test: manual app usage Change-Id: I2db3aa73edcb80da25ead64205011705f0beef91
2017-08-18Disable hwui blending for first draw to main FBO Arun
bug:34809371 In some applications, the first draw is not opaque - either because the application is misbehaved, or because hwui is not able to reliably tell whether the layer is opaque or translucent. This is undefined behaviour in OpenGL ES and has a significant performance and bandwidth impact on some tiler GPUs as it requires loading the previous frame's color data. This change disables blending in that case and also for effectively opaque blend modes (SRC=GL_ONE, DST=GL_ZERO). It increases performance by ~10% for Leanback CTS on some low-end GPUs (gradient layer that hwui incorrectly believes to be translucent). Test: manual - visual inspection on fugu (nexus player) Change-Id: I2cbf1c76678acae1a36923e72fd18ed55cd89dc2
2017-07-18Fix Skia pipeline readback for non-portrait mode Stan Iliev
Apply correctly the image transform matrix passed to SkiaOpenGLReadback::copyImageInto. This is fixing 13 of 14 failing android.view.cts.PixelCopyTest tests (the last failing test is caused by missing wide gamut support). Test: Ran CtsViewTestCases CTS tests for Skia and HWUI pipelines. Bug: 63629735 Change-Id: I67fb06968e21f9aa88973c076870b5557f15d483
2017-07-06Add missing notifyPixelsChanged John Reck
Fixes: 63400947 Test: CTS test PixelCopyTest#testReuseBitmap Change-Id: Iad6fe331f84415528c1858a1fdbf26bce784cd53
2017-06-29Merge "Selectively disable filtering if estimated safe" into oc-dev John Reck
am: 38c97237e3 Change-Id: Ic3be7167429e8cd6a291ac0465e883522afcf9e3
2017-06-28Selectively disable filtering if estimated safe John Reck
If the output matches the source rect then use GL_NEAREST instead of GL_FILTER. This is a more pixel-exact capture. Bug: 38242146 Test: CtsUiRendering & CtsViewTestCases:.PixelCopyTest passes on fugu Change-Id: I9f57a4124374568f83d45fdc8f83cc767ded888a
2017-06-16Add support for RGBA_F16 readbacks Romain Guy
WCG windows render into RGBA16F surfaces, we need to give the readback API the ability to read the raw source data for testing. Bug: 62728191 Test: CtsViewTestCases Change-Id: I93ead84207dab38fba02d4419b5ae18df9555f8e
2017-05-09fix circular dependency libnativewindow <-> libui Mathias Agopian
Bug: 37647680, 37648355 Test: compile, manual Change-Id: I00d72d063c252739ca5a63dbf84424ad4f837f89
2017-04-18bitmaps and pixelrefs no longer need lock/unlock Mike Reed
Test: covered by CtsGraphicsTestCases and hwui_unit_tests Change-Id: I42a25961a2eb3755d2fd22a617aa21a24ec0994f
2017-01-10Break Layer class into Gl and Vulkan subclasses Greg Daniel
Test: manual testing Change-Id: Ibd2beed39de3ac6da7448e96496253cfe427dfbb
2016-12-16Add new RGBA_F16 bitmap config Romain Guy
This configuration uses 64 bits per pixel. Heach component is stored as a half precision float value (16 bits). Half floats can be decoded/encoded using android.util.Half. RGBA_F16 bitmaps are used to decode wide-gamut images stored in 16 bit formats (PNG 16 bit for instance). aapt is currently not aware of PNG 16 bits so such files must be placed in raw/ resource directories. This first pass provides only partial drawing support with hardware acceleration. RGBA_F16 bitmaps are stored in linear space and need to be encoded to gamma space with the appropriate OETF to be rendered properly on Android's current surfaces. They are however suitable for linear blending. Full rendering support will be provided in a future CL (BitmapShaders might be a bit tricky to handle properly during shader generation). Bug: 32984164 Test: bit CtsGraphicsTestCases:android.graphics.cts.BitmapRGBAF16Test Change-Id: I328e6b567441a1b9d152a3e7be944a2cf63193bd
2016-12-15Actually fix pixelcopy for 90/180/270 rotation John Reck
