Mohan Maiya f16e94cd 2020-06-17T10:43:19 Prefer retrieval of TLS values through ASM code on Android On the Android platform prefer using the ASM code to retrieve TLS context object even for single threaded apps. This helps get rid of a branch in GetGlobalContext() and GetValidGlobalContext() further improving the CPU perf of TLS operations. Bug: angleproject:4717 Change-Id: I58d3d3b7061d613b24f945c07bed497c7c4be25c Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2250318 Commit-Queue: Mohan Maiya <m.maiya@samsung.com> Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Courtney Goeltzenleuchter <courtneygo@google.com>
Mohan Maiya 33c28e35 2020-06-12T08:17:47 Optimize thread specific storage and retrieval with native ASM Android reserves specific TLS slots to store thread specific values. Given that the Context object gets queried on every call we leverage Android's ASM code to improve the speed of this operation. TLS_SLOT_OPENGL is an unused slot in Android and using that in combination with the ASM code,rather than using the pthread API, allows angle to store and retrieve thread specific context object much more efficiently.

Brandon Schade 0a6e118d 2020-01-27T13:37:29 Change g_Mutex from std::mutex to std::recursive_mutex When running flatland on android-10.0.0_r21 (Pixel 3), libgui's ~EglImage calls eglTerminate which grabs angle's EGL entry point mutex. The path continues to libvulkan where eventually another egl call happens (eglDestroyImageKHR) and it will attempt to take the mutex at the entry point again. So we try to get the mutex multiple times from the same thread. Change this mutex to a recursive_mutex to allow for this re-entry of EGL calls Tests: android-10.0.0_r21/frameworks/native/cmds/flatland Bug: angleproject:4354 Change-Id: If8a817df45e9f58d5f06884510350e17d7127fa9 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2029218 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Cody Northrop <cnorthrop@google.com>
Stuart Morgan 9d737966 2019-08-14T12:25:12 Standardize copyright notices to project style For all "ANGLE Project" copyrights, standardize to the format specified by the style guide. Changes: - "Copyright (c)" and "Copyright(c)" changed to just "Copyright". - Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1"). - Fixed a small number of files that had no copyright date using the initial commit year from the version control history. - Fixed one instance of copyright being "The ANGLE Project" rather than "The ANGLE Project Authors" These changes are applied both to the copyright of source file, and where applicable to copyright statements that are generated by templates.

Geoff Lang 067687f4 2019-05-29T12:48:49 Removal global locks from GL entry points. Always lock in EGL. The ANGLE Vulkan backend is now thread safe for non-share group contexts. This means that a global GL lock only adds overhead for most use cases. Remove the angle_force_thread_safety gn argument.

Jamie Madill 77db6f4a 2018-09-23T17:28:55 Use global Context lookup in single-threaded cases. In single-threaded cases we don't need to use a TLS lookup for the current Context. Assume a global context has 3 states: unset, set, and multi-threaded: * global context unset -> set the global context * global context set, matches TLS context -> set the global context * global context set, doesn't match TLS -> set multi-threaded * global context multi-threaded -> leave it This also inlines the global context/TLS check into global_state.h. Increases performance of the binding perf overhead test by up to 25% and the draw call perf test by up to 3%.

Geoff Lang 7b8f3c9b 2016-11-10T10:42:48 Encapsulate the thread local storage into an egl::Thread class. Instead of having separate GetGlobal* functions, interact with the global objects through a single Thread object. This reduces the number of TLS lookups in many EGL functions and allows the Thread object to be passed down to other objects if needed.
