Hi Prabindh, I and probably many others very much appreciate the effort that TI does not just release graphics drivers blindly, but also tries to publish documentation and builds a community around it. I'm also aware of the DRM drivers for Linaro/Ubuntu and I know the Android releases (in desp

I am not aware of VSYNC related issues in Beagleboard/bone platforms. If there are, please point a reference for me to attack. For OMAP4/Pandaboard, it is recommended to check on Pandaboard.org forums. As I mentioned earlier in the thread, I stopped supporting plain fb on OMAP4/Panda more than a

Hi, I bumped into a similar problem with qt5beta1 recently and got it solved by creating a /qtbase/bin/qt.conf: [EffectivePaths] Prefix= The directory is the one where 'make install' initially put all the files and directories like mkspecs, etc. This assumes you're still calling qma

Hi, one final word to this list on my fix. I think that the fix I did to Qt5 is not in good shape to be integrated. My fix interfaces directly with OMAP-specific ioctl's to a linux framebuffer device in code that is generic to all egl platforms. I'll continue to discuss this first with Prabind

I personally would rather you did not take this off this this thread, since we have many TI customers/users, and prying this type of information out of people is the trickiest part of getting Qt 5 running optimally on hardware. Of course it is at your discretion, but there are almost certainly oth

Stephan - Waiting for vsync in user mode is quite different from hooking onto the vsync from kernel (in omaplfb), and ltrace/strace would not show waiting in the kernel mode. Since this is TI specific, and the Qt5 specific issue seems to be resolved, please send me a direct mail, if so require

Hi Prabindh, that one went out too quickly... :-) I think my last posting wasn't that precise. The TI package I'm using clearly lacks VSYNC support for OMAP4. None of the SDK demos runs at a constant frame rate (some at 150+ fps), none of them uses a blocking vsync ioctl (simply ltrace/strace

Good to know that the flip mode solved the issue. You might want to update to a later kernel revision and check. Vsync handling is more complex than it appears, over fb drivers. regards Prabindh -Original Message- From: interest-bounces+prabu=ti@qt-project.org [mailto:interest-bou

Just wanted to point out that the EGL spec seems to specify that VSYNC should be enabled by default: http://www.khronos.org/registry/egl/sdk/docs/man/xhtml/eglSwapInterval.html "If interval is set to a value of 0, buffer swaps are not synchronized to a video frame, and the swap happens as soon

Hi Prabindh, couldn't wait, so I already tried yesterday, but then went to bed :-). It worked immediately! I added an ioctl(fbdev, WAITFORSYNC) to qt/qtbase/src/platformsupport/eglconvenience/qeglplatformcontext.cpp and after that all animations were butter smooth immediately. I also noticed th
