| | | | | | | When a texture or renderbuffer is still attached to framebuffer but is getting deleted, it should also be detached from framebuffer. Change-Id: Ide2c2a0e36ca8bf58f9351a17b78b76ebd507c12
* emulator/opengl: Fix glShaderSource() signature.David 'Digit' Turner2014-11-2510-9/+10
| | | | | | | | | | | | | The glShaderSource() function really takes a 'const GLchar* const*' parameter, not 'const GLchar**'. This creates issues when compiling the auto-generated encoders created with the latest version of 'emugen' and the GL2 Khronos headers. This patch is used to fix the issue. Note that it requires defining a new type in gl2.types, as well as fixing the signature of misc functions in the translator. Change-Id: I750f95f2e33d83b3b5563642ad7f87e4b8a37f35
* emulator/opengl/emugen: Add new 'flushOnEncode' entry point flag.David 'Digit' Turner2014-11-251-0/+3
| | | | | | | | | | | | | This adds a new flag that can be applied to entry points for 'emugen', named 'flushOnEncode'. When used, the generated encoder will call stream->flush() just after adding bytes to the stream. This is needed to match the manual change that was performed in the renderControl encoder in the following patch: https://android-review.googlesource.com/#/c/95864/ Change-Id: I8cc8fdb0d38ef27e8ba646c83d717166400babfd

* emulator/opengl/emugen: Remove accessor functions.David 'Digit' Turner2014-11-253-54/+54
| | | | | | | | This patch simplifies the generated encoders and decoders by getting rid of the accessor functions (e.g. set_glDrawElementsData) given that all fields are public and can be written to directly. Change-Id: I15f4caac95e4d5f1e24a1a5838622600c6bc3207

* Properly handle shader program deletionbohu2014-11-183-1/+42
| | | | | | | | | When deleting a program that is still in use, its delete status should set to true and the actual deletion should happen later when the program is not in use. Change-Id: I821312997d372ed4773033ba373a8c792f6d7ba9 (cherry picked from commit 9b3c3647baf41e15cf9564df4b974162a7135873)
* Properly handle shader deletionbohu2014-11-183-3/+61
| | | | | | | | | | | | When deleting a shader that is still attached to program, it should not be deleted immediately. Instead, it should be marked for deletion. When a program is deleted, its shaders should be detached. When a shader is detached, it should be deleted if it is marked for deletion. Change-Id: I481dbfe37e3ad4af454574b75d157bdfeb1c9cdd (cherry picked from commit bc42a0598f6e5ffb0ebd646e0bad8d94c50ec193)

| | | | | | | | | | This commit clears m_src of ShaderParser in setSrc() method before reading new shader source code so that any previous source code won't be prefixed to new shader source code. Change-Id: Iacc98b32aea380d1e4503c37b86f5db55263e667 (cherry picked from commit ba8d8fef8f76d86f90f5cc7774e1e0f4fb507b86)
* emulator/opengl: Cleanup build files + remove obsolete tests.David 'Digit' Turner2014-08-278-84/+56
| | | | | | | | | | | | | | | | | | | | | | This patch cleans up the build files for the GPU emulation libraries (i.e. there is no need to test for BUILD_EMULATOR_64BITS anymore, filtering is now handled by the build system directly). + Remove a bunch obsolete tests, which were not unit tests, despite their name beginning with ut_xxxx. Which includes removing dependency on SDL too. + Remove -m64 and -fPIC flags from compilation. These are not necessary anymore (again, the build system now takes charge of placing them when necessary), and generated link-time warning when building Windows executables. + Remove a few declarations related to the now-obsolete platform build (these libraries are only built with the emulator's build system now). Change-Id: I27c28979c42cd51f2fe9e30edd4141136e80ee03
* emulator/opengl: Remove out-of-process handling code.David 'Digit' Turner2014-07-095-131/+9
| | | | | | | | | | | This removes the last pieces of shared/OpenglOsUtils which were never used since the code in render_api.cpp always used thread-based rendering, instead of process-based one. This feature could be re-implemented in the future, if really desirable. Change-Id: I551e0f3d6d5a06ff66cb40b007e2b24c295f1dd8

* emulator/opengl: Add global lock to libOpenglRender.David 'Digit' Turner2014-07-084-14/+17
| | | | | | | | | | | This patch ensures that all render threads use the same global lock to synchronize calls to the underlying GLES/EGL libraries. Original patch from Thomas Knych (thomaswk@google.com) BUG=9627179 Change-Id: I8ac9a43bc30bba8a9a06f832cf29e72263d946ce
* emulator/opengl: Prepare for 64-bit build changes.David 'Digit' Turner2014-06-118-8/+8
| | | | | | | | | | | This patch slightly modifies the build files for the GPU emulation libraries to prepare for future changes in the emulator-specific build system that will be necessary to support Win64 binaries. The main difference is the introduction of 64-bit versions of the emugl-begin-host-<type> macros, named emugl-begin-host64-<type>. Change-Id: Ib40c030fa407b0ed951755dd9b007fda85778e03
* emulator/opengl: Fix compilation with Mingw64 toolchain.David 'Digit' Turner2014-06-041-2/+2
| | | | | | | | | | When using the newest Mingw64 toolchain, both the forward declaration and the definition of functions need to use GLAPI / GLAPIENTRY or the compiler will complain. BUG=15402623 Change-Id: Ida9e1cb9b177759e7d6688dc1d883dd856abda04
* emulator/opengl: Fix GPU emulation library crash on Windows.David 'Digit' Turner2014-06-041-2/+2
| | | | | | | | | | | | | | | The definitions of two EGL translator functions were missing EGLAPI / EGLAPIENTRY macros. On Windows, these enforces the __stdcall procedure call modifier, which changes the way the stack pointer is modified on function exit. Without this patch, a call to these function will result in a corrupted stack pointer in the caller, quickly followed by a random crash. BUG=15402623 Change-Id: Ia0f7ebef29e1252086fb59ebf2e6f907c2a69487
* opengl: rcOpenColorBuffer must be synchronousJesse Hall2014-05-275-6/+22
| | | | | | | | | | | | | The gralloc register_buffer() function, which calls rcOpenColorBuffer, must actually increment the reference count before returning. Otherwise the buffer allocator may release its reference before the client has obtained one, and the buffer will be freed prematurely. Since rcOpenColorBuffer was just sending a message to the host without waiting for it to be received/processed, this guarantee was not met. Adding a return value makes the call synchronous. Bug: 12988668 Change-Id: I8b2399cfb0f600f99b3387f630343291b59bc9a6
* emulator/opengl: A few debugging, stability improvements to emuglKen Mixter2014-05-212-2/+2
| | | | | | | | | | | | | | | | | | | * Zero output parameters so that errors don't return random data (even if the target code was careful to zero its output parameters.) Spec says that we will not modify values in case of an error, which is not currently possible, but at least this means we return deterministic values. * Similarly, avoid passing uninitialized data if an error occurs during getting the viewport. * Fix a bug where glGetError may be called when NULL is decoded in CHECK_GL_ERROR mode. * Output more information about the stream in DEBUG_PRINTOUT mode to help separate from multiple streams. Change-Id: I31706b92642efe4c7ed38d178b49e72835a9c9a6
* emulator/opengl: Fix GCC 4.8 warnings.David 'Digit' Turner2014-04-283-27/+27
| | | | | | | | This fixes a few compiler warnings when building the GPU emulation libraries with GCC 4.8. Note that GLbyte is defined as khronos_int8_t which is signed! Change-Id: I52027cd2eb20d6162983319f22d4da150ff514ed
* emulator/opengl: Backport fixes from master branch.David 'Digit' Turner2014-04-172-1/+15

* emulator/opengl: Fix misc. compiler warnings.David 'Digit' Turner2014-04-017-35/+27
| | | | | | | These warnings appear when building the sources through the emulator's standalone build system, not the platform one. Change-Id: Ib5d51cf6211f32763be00c7436ae14c06f76b436
* emulator/opengl: Fix Windows EGL queryConfigs().David 'Digit' Turner2014-04-011-2/+2
| | | | | | | | | | The function uses DescribePixelFormat() which doesn't return a count, but a maximum index, in a base-1 list of possible formats, so adjust the code accordingly. See http://msdn.microsoft.com/en-us/library/windows/desktop/dd318302(v=vs.85).aspx Change-Id: Id0cc92249348e6c845570adaaf4c280721a194bb
* emulator/opengl: Fix eglWaitGL implementation.David 'Digit' Turner2014-04-011-1/+3
| | | | | | | | | | | The eglWaitEGL implementation didn't restore the previous bound API after calling eglWaitClient. This probably isn't a big concern for emugl correctness, but fixing this removes a compiler warning. See http://www.khronos.org/registry/egl/sdk/docs/man/xhtml/eglWaitGL.html Change-Id: I143ffeeefa01aff502d27d4e1d6f892f0d1efe5b
* emulator/opengl: Allow standalone build.David 'Digit' Turner2014-03-119-62/+186
| | | | | | | | This patch improves the build files for the GPU emulation libraries to allow them to be built directly with the emulator's own standalone build system. Change-Id: I205392bdfe4223a5c43fa67e24a2beffcbcbc07a
* emulator/opengl: Remove libcutils/libutils/liblogDavid 'Digit' Turner2014-03-112-4/+4
| | | | | | | | Final patch to completely remove dependencies on libcutils/libutils/liblog from the host-side GPU emulation libraries. Change-Id: I84a058bbd0ca676b18c0b0a094ac8bae692f9c94
* emulator/opengl: Remove Android-specific thread_store.David 'Digit' Turner2014-03-113-35/+73
| | | | | | | | | | | | | | | | | This patch removes the use of the 'thread_store' class from <utils/threads.h> by providing its own implementation instead under shared/emugl/common/thread_store.h, plus appropriate unit tests. Note that unlike the Android version, this properly destroys the thread-local values on thread exit (instead of leaking them). + Provide a LazyInstance class used to perform thread-safe lazy initialization of static variables without the use of C++ constructors. Change-Id: Iabe01fbd713c6872b5fe245d7255c3c03749a88a
* emulator/opengl: Remove android::Mutex.David 'Digit' Turner2014-03-1122-185/+145
| | | | | | | | | | | This patch removes the dependency on android::Mutex from <cutils/threads.h> by providing a custom implementation, which is a simple wrapper around pthread_mutex_t / CriticalSection, under shared/emugl/common/mutex.h + Provide unit tests. Change-Id: I379ef0c480c478ab9ba5f2faaf8274267eff37ba
* emulator/opengl: Remove compiler warningsDavid 'Digit' Turner2014-03-063-7/+1
| | | | | | | This patch removes a few minor compiler warnings related to unused local variables. Change-Id: Icd4b3b478dce0c38cc1dd04419db7350dcbdb8f6
* emulator/opengl: Refactor SmartPtr implementation.David 'Digit' Turner2014-01-2112-186/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | This gets rid of two copies of SmartPtr.h and replaces them with a single implementation under shared/emugl/common/smart_ptr.* Note that this uses a new include path rooted at the shared/ directory for classes that are likely to be built both for the host and the device (in case we back-port this to device/generic/goldfish/opengl/ in the future). + Add a gtest-based set of unittests, after building, just call 'emugl_common_host_unittests' to run it. Note that this probably needs a 64-bit version as well, will come later once I find a way to build GTest for 64-bits without breaking the platform build :-) Also note that this moves the class to the 'emugl' namespace, in order to make the code easier to build out of the platform tree, and embed it in other projects. More classes will be transitioned / refactored in future patches. AOSP_BUG=64806 Change-Id: Ieb326c5f3f002a21537b8a391a82ce2ef9925073
* emulator/opengl: Prepare out-of-platform build with SDL.David 'Digit' Turner2014-01-181-0/+282
| | | | | | | | | | | A small patch to prepare for the out-of-platform-tree build. This ones places SDL-related definitions in a new build file (sdl.mk) and provide a way for the emulator's build system to provide its own SDL compiler and linker flags. + Add missing KHR/khrplatform.h file. Change-Id: I496f1a49730ffbfae80a074e09611bd07777cf1a
* emulator/opengl: Get rid of all compiler warnings (Linux).David 'Digit' Turner2014-01-1810-63/+74
| | | | | | | | | | | This patch gets rid of all compiler warnings for the GPU emulation libraries when building on a Linux host. Note that GLcommon/GLutils.h now provides two new functions to perform 'safe' type casts between unsigned integers and pointers: SafePointerFromUInt() and SafeUIntFromPointer().

This means that EGL won't return any configs at all with alpha == 0. The default config chooser in GLSurfaceView requires a config with alpha == 0. This means that previously, this view failed to start up on the emulator on OS X, unless set up with a non-default config chooser. Change-Id: I2bf3e92a026c525a97d6746e491d920ce127787f

The previously incorrect pbuffer texture parameters had different effects on different GPUs/drivers. On a Nvidia GT 650M, the buffers were rendered properly but glReadPixels calls were inverted, while Intel HD 3000/4000 seemed to get the rendering inverted as well. By passing proper pbuffer texture parameters, the bug (which in itself was no driver bug but inconsistent behaviour when given invalid parameters) vanishes.
