Hello All,

I am running mesa-7.10.2 on my qemu machine having  /dev/fb0 with following
configuration

./configure --prefix=/opt/mesa-arm-genoa-new --host=arm-linux
--build=i686-linux --enable-gles2 --with-x=no --with-egl-platforms=fbdev
 --with-egl-displays=fbdev --with-driver=no   --disable-glu --disable-glw
--disable-glut --disable-gl-osmesa --disable-opengl --enable-debug
--enable-gles-overlay

. I want to run some stack which runs gles2 as backend and requires GL_ARGB
 pixel format to execute APIs glTexImage2D and glReadPixel , but above
ported mesa code base is showing GL_BRGA_EXT   after calling following
API. glGetIntegerv(GL_IMPLEMENTATION_COLOR_READ_FORMAT, &readFormat);

Please suggest me how i can configure Mesa for GL_ARGB pixel format.


Regards
Vivek
