* Disable EGL hibernation due to jankJesse Hall2012-05-042-7/+13
| | | | | | | | | | Hibernating EGL takes a long time (>100 ms) and blocks all other rendering. During window animations, the outgoing activity begins hibernation before the animation stops, causing visible stutter. Hibernation is still available by setting 'BOARD_ALLOW_EGL_HIBERNATION := true' in the devices BoardConfig.mk Change-Id: Iab4e00723a1adcd97481e81b2efdc821b3e9712f
* Fix deadlock when cleaning objects in eglTerminateJesse Hall2012-04-172-29/+79
| | | | | | | | | | | | | | | | | | When eglTerminate() is called with a window surface still exists, a deadlock would occur since egl_display_t::terminate() holds a lock while destroying the window surface, which calls onWindowSurfaceDestroyed() which attempts to take the same lock. This change refactors the hibernation code and data into a separate object with its own lock, separate from the egl_display_t lock. This avoids the deadlock and better encapsulates the hibernation logic. The change also fixes a bug discovered incidentally while debugging: hibernating after calling eglTerminate() succeeds, but will cause awakens from subsequent eglInitialize() to fail. We will no longer hibernate a terminated display. Change-Id: If55e5bb603d4f8953babc439ffc8d8a60af103d9
* Hibernate the EGL implementation when idleJesse Hall2012-04-096-17/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | If the EGL implementation supports the EGL_IMG_hibernate_process extension, use it to hibernate (and hopefully release memory or other resources) when the process isn't actively using EGL or OpenGL ES. The idleness heuristic used in this change is: (a) Wake up when entering any EGL API call, and remain awake for the duration of the call. (b) Do not hibernate when any window surface exists; this means the application is very likely in the foreground. (c) Do not hibernate while any context is made current to a thread. The app may be using a client API without the EGL layer knowing, so it is not safe to hibernate. (d) Only check these conditions and attempt to hibernate after a window surface is destroyed or a thread's context is detached. By not attempting to hibernate at the end of every EGL call, we avoid some transient wakeups/hibernate cycles when the app is mostly idle, or is starting to become active but hasn't created its window surface yet. On a Galaxy Nexus, hibernating frees 1567 VM pages from the process. Both hibernating and waking can take anywhere from 30ms to over 100ms -- measurements have been very inconsistent.

* Increment/decrement a counter around EGL callsJesse Hall2012-04-096-91/+169
| | | | | | | | | | | | This is in preparation for a change that will hibernate the underlying EGL when idle. Instead of a bare egl_display_t*, get_display() now returns a egl_display_ptr, which acts like a smart pointer. The "wakecount" counter managed by the smart pointer isn't used for anything in this change. It will be used to make sure we don't hibernate when any thread is in an EGL call, without having to hold a mutex for the duration of the call. Change-Id: Iee52f3549a51162efc3800e1195d3f76bba2f2ce

* fix a dead-lock in eglMakeCurrentMathias Agopian2012-02-032-22/+54

* fix a race condition in eglMakeCurrent()Mathias Agopian2012-01-303-35/+52
| | | | | | | | | | | | | | it would happen when a context was made non-current, in this case we would call the implementation's eglMakeCurrent() which would succeed, if we're rescheduled at that point, another eglMakeCurrent() could make that context current to another thread, however, when we came back to the original call we would overwrite egl_context_t internal state. this is fixed by moving the critical section under egl_display_t's lock.

Multiple EGL contexts are handled properly: Corresponding to each EGLContext, a GLTraceContext with a unique ID is created. On eglMakeCurrent, the appropriate GLTraceContext is set and is used while tracing subsequent GL Calls in that thread. Change-Id: I34076376d3e5af205c87c7396ea47659844abd6e

| * glestrace: Framework for GLES tracing librarySiva Velusamy2011-12-026-48/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a framework for tracing GLES 1.0 and 2.0 functions. It is missing a lot of features, but here are the things it accomplishes: - Stop building the glesv2dbg library, and build the glestrace library instead. - Replace the hooks for glesv2dbg with the ones for glestrace. - Add the basics for the trace library. Currently, this traces all GL functions, but not all required data is sent for all the functions. As a result, it will not be possible to reconstruct the entire GL state on the host side. The files gltrace.pb.* and gltrace_api.* are both generated using the tools/genapi.py script. Change-Id: Id60a468f7278657f008bc6ea1df01f9bdfecfdd3

| | | | | | | | | | | | | | | | | | | | | | This change introduces two new BoardConfig variables to control the size limits of the EGL blob cache. MAX_EGL_CACHE_ENTRY_SIZE is the size limit for values inserted into the cache, and MAX_EGL_CACHE_SIZE is the size limit for all entries in the entire cache (including both keys and values). If either of these BoardConfig variables are not defined then a default size limit is used instead. Change-Id: I6703d93f966b6389c6499f23d841e42339f9c9d7
