<div><br></div><div>Hello All</div><div> </div><div> I am using Mesa-7.10.2 stack. </div><div><br></div><div>I am trying to run EGL with egl_gallium state trackers (GLES=>EGL=>egl_gallium=>fbdev) over fbdev with following </div>
<div><br></div><div>configuration</div><div><br></div><div><br></div><div>./configure --prefix=/opt/mesa-arm-genoa-new --host=arm-linux --build=i686-linux --enable-gles2 --with-x=no </div><div><br></div><div>--with-egl-platforms=fbdev --with-egl-displays=fbdev --with-driver=no --disable-glu --disable-glw --disable-glut </div>
<div><br></div><div>--disable-gl-osmesa --disable-opengl --enable-debug --enable-gles-overlay</div><div><br></div><div>I am able to run applications which can draw directly on scanout surfaces/pbuffer (es2gears).</div><div>
<br></div><div>I want to run application which uses eglCreateImageKHR (with user defined pixmap structures) to make textures</div><div>and eglCreatePixmapSurface (with user defined pixmap structures) to create a Pixmap surfaces. Since Native_fbdev.c doesnot </div>
<div><br></div><div>support pixmap surfaces both calls fail.</div><div> I tried to put pixmap support in native_fbdev.c with following steps</div><div>1)putting a function in </div><div> fbdpy->base.destroy = fbdev_display_destroy;</div>
<div> fbdpy->base.get_param = fbdev_display_get_param;</div><div> fbdpy->base.get_configs = fbdev_display_get_configs;</div><div><br></div><div> /*Adding function to create PIXMAP surface*/</div><div> fbdpy->base.is_pixmap_supported = fbdev_display_is_pixmap_supported;</div>
<div> fbdpy->base.create_pixmap_surface = fbdev_display_create_pixmap_surface;</div><div><br></div><div>2)Added support flag true in native_config</div><div> pixmap_bit=true;</div><div><br></div><div>I am able to get finctions eglCreateImageKHR/eglCreatePixmapSurface run successfully able to get user defined pixmap </div>
<div>to native_fbdev by typecasting it ot EGLNativePixmaptype. But I am not able to draw any texture on EGLImage. I suspect </div><div>glEGLImageTargetTexture2DOES is not working properly with EGLImage returned from eglCreateImageKHR.</div>
<div><br></div><div>I dont know how I can make it visible to GLES by calling function like glEGLImageTargetTexture2DOES.</div><div><br></div><div>I am very new to GLES and EGL . Please provide me suggestions so that I can proceed further.</div>
