|/ | | | | | | | | | | | - Process is killed by system with SIGBUS signal if it writes data to mapped sparse file on full filesystem. - Allocate space using write() function instead of ftruncate() to avoid creation of sparse files on full filesystem.

* gltrace: Allow receiving commands of length > 4Siva Velusamy2012-05-163-9/+53
| | | | | | | | | | | | | Currently, gltrace offers very few trace collection options. As a result, these options are encoded in a single integer. The trace control task simply receives integers and interprets them as commands. This patch changes the control protocol to first receive the command length followed by the actual command itself. This allows for future flexibility to provide enable other commands. Change-Id: Id5f56c80a025bbbe7613ab4457e092732e7d9dc9
* Disable EGL hibernation due to jankJesse Hall2012-05-043-7/+17
| | | | | | | | | | 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

| * Added an EGLTest for eglTerminateDaniel Lam2012-04-162-0/+33
| | | | | | | | | | | | | | This tests if eglTerminate can succeed while objects are leaked. Currently the test fails because of a deadlock. Change-Id: Ibe26edfda28691284d0674e803e8d3114f3ce4c6
* | 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 Hall2012-04-097-18/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| * gltrace: Send vertex attribute data after glDraw() call.Siva Velusamy2012-03-017-51/+418
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables tracing of vertex attribute data that is specified using glVertexAttribPointer(). At the time the glVertexAttribPointer() call is made, we only receive a pointer in client space, without any indication of the size (# of attributes). This size is known only at the time of the glDraw() call. This patch generates a new message glVertexAttribPointerData() when a draw call is issued that contains the vertex attribute data. A glDrawArrays() call directly gives the size of data to copy. A glDrawElements() call gives the indices to copy. In such a case, all data between the min & max indices drawn are copied and sent to the host. To support glDrawElements() with an element array buffer, this patch also adds state that maintains a copy of all element array buffers. Change-Id: I434da794a0aa9ada8e7474e219ffb1d79b183ecf
