    Harmattan Platform SDK/QEMU Hardware Acceleration

    How to get it working? QEMU runs too slow and it's almost unusable.

    Code:
    arm-qemu-rm680_linux_i686$ LD_LIBRARY_PATH=lib bin/dgles2test
    Function glBlendEquationSeparate not found!
    Tried on two slightly different configurations:
    Code:
    $ glxinfo | grep -i "opengl\|direct" && lspci | grep -i vga
    direct rendering: Yes
    OpenGL vendor string: NVIDIA Corporation
    OpenGL renderer string: NVS 3100M/PCI/SSE2
    OpenGL version string: 3.2.0 NVIDIA 195.36.24
    OpenGL shading language version string: 1.50 NVIDIA via Cg compiler
    OpenGL extensions:
        GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access, 
    01:00.0 VGA compatible controller: nVidia Corporation NVS 3100M (rev a2)
    Code:
    $ glxinfo | grep -i "opengl\|direct" && lspci | grep -i vga
    direct rendering: Yes
    OpenGL vendor string: NVIDIA Corporation
    OpenGL renderer string: GeForce 8400 GS/PCI/SSE2
    OpenGL version string: 3.2.0 NVIDIA 195.36.24
    OpenGL shading language version string: 1.50 NVIDIA via Cg compiler
    OpenGL extensions:
        GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access, 
    01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 8400 GS] (rev a1)
    both use Ubuntu 10.04 x86 and nvidia proprietary driver

    According to glx-info you have it working in both cases.

    Yeah, but I have about 0.5 frames per second. Couldn't it be little bit faster? There is the log from QEMU http://pastebin.com/EiVJF4Qr it complains several times about some missing OpenGL stuff

    If anyone is still looking for solution:
    Code:
    echo "export  DGLES2_BACKEND=glx" >> ~/.profile
    Framerate in my case has increased dramatically! Found at http://harmattan-dev.nokia.com/docs/...th_Qt_SDK.html
