Hello All
I am using Mesa-7.10.2 stack.
I am trying to run EGL with egl_gallium state trackers
(GLES=>EGL=>egl_gallium=>
fbdev) over fbdev 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 am able to run applications which can draw directly on scanout
surfaces/pbuffer (es2gears).
I want to run application which uses eglCreateImageKHR (with user defined
pixmap structures) to make textures
and eglCreatePixmapSurface (with user defined pixmap structures) to create a
Pixmap surfaces. Since Native_fbdev.c doesnot
support pixmap surfaces both calls fail.
I tried to put pixmap support in native_fbdev.c with following steps
1)putting a function in
fbdpy->base.destroy = fbdev_display_destroy;
fbdpy->base.get_param = fbdev_display_get_param;
fbdpy->base.get_configs = fbdev_display_get_configs;
/*Adding function to create PIXMAP surface*/
fbdpy->base.is_pixmap_supported = fbdev_display_is_pixmap_supported;
fbdpy->base.create_pixmap_surface = fbdev_display_create_pixmap_surface;
2)Added support flag true in native_config
pixmap_bit=true;
I am able to get finctions eglCreateImageKHR/eglCreatePixmapSurface run
successfully able to get user defined pixmap
to native_fbdev by typecasting it ot EGLNativePixmaptype. But I am not able
to draw any texture on EGLImage. I suspect
glEGLImageTargetTexture2DOES is not working properly with EGLImage returned
from eglCreateImageKHR.
I dont know how I can make it visible to GLES by calling function like
glEGLImageTargetTexture2DOES.
I am very new to GLES and EGL . Please provide me suggestions so that I can
proceed further.
For convenient i am putting my code which I have inserted to native_fbdev.c
