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=><div id=":1gu">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 static struct native_surface * fbdev_display_create_pixmap_surface(struct native_display *ndpy, EGLNativePixmapType pix, const struct native_config *nconf) { printf("START %s %s\n", __FUNCTION__, __FILE__); fbdev_pixmap *pixmap = (fbdev_pixmap *)pix; /*Trying To print pixmap detail*/ printf("pixmap->height ::%d\n", pixmap->height); printf("pixmap->width ::%d\n", pixmap->width); printf("pixmap->bytes_per_pixel ::%d\n", pixmap->bytes_per_pixel); printf("pixmap->buffer_size ::%d\n", pixmap->buffer_size); printf("pixmap->red_size ::%d\n", pixmap->red_size); printf("pixmap->green_size ::%d\n", pixmap->green_size); printf("pixmap->red_size ::%d\n", pixmap->blue_size); printf("pixmap->alpha_size ::%d\n", pixmap->alpha_size); printf("pixmap->luminance_size ::%d\n", pixmap->luminance_size); printf("pixmap->flags ::%d\n", pixmap->flags); printf("pixmap->data ::%p\n", pixmap->data); struct fbdev_display *fbdpy = fbdev_display(ndpy); struct fbdev_surface *fbsurf; fbsurf = CALLOC_STRUCT(fbdev_surface); if (!fbsurf) return NULL; fbsurf->fbdpy = fbdpy; fbsurf->width = pixmap->width; fbsurf->height = pixmap->height; fbsurf->type = FBDEV_SURFACE_TYPE_PIXMAP; fbsurf->pixmap = pix; fbsurf->rsurf = resource_surface_create(fbdpy->base.screen, nconf->color_format, PIPE_BIND_RENDER_TARGET | PIPE_BIND_DISPLAY_TARGET | PIPE_BIND_SCANOUT ); if (!fbsurf->rsurf) { FREE(fbsurf); return NULL; } resource_surface_set_size(fbsurf->rsurf, fbsurf->width, fbsurf->height); fbsurf->base.destroy = fbdev_surface_destroy; fbsurf->base.present = fbdev_surface_present; fbsurf->base.validate = fbdev_surface_validate; fbsurf->base.wait = fbdev_surface_wait; printf("END %s %s\n", __FUNCTION__, __FILE__); return &fbsurf->base; } static struct native_display * fbdev_display_create(int fd, struct native_event_handler *event_handler, void *user_data) { struct fbdev_display *fbdpy; fbdpy = CALLOC_STRUCT(fbdev_display); if (!fbdpy) return NULL; fbdpy->fd = fd; fbdpy->event_handler = event_handler; fbdpy->base.user_data = user_data; if (!fbdev_display_init(&fbdpy->base)) { FREE(fbdpy); return NULL; } fbdpy->base.destroy = fbdev_display_destroy; fbdpy->base.get_param = fbdev_display_get_param; fbdpy->base.get_configs = fbdev_display_get_configs; /*Vivek:: 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; fbdpy->base.modeset = &fbdev_display_modeset; return &fbdpy->base; } static boolean fbdev_display_is_pixmap_supported(struct native_display *ndpy, EGLNativePixmapType pix, const struct native_config *nconf) { printf("START %s %s\n", __FUNCTION__, __FILE__); struct fbdev_display *fdpy = fbdev_display(ndpy); enum pipe_format fmt; uint depth; depth = 32; //hard coded for 4bpp switch (depth) { case 32: fmt = PIPE_FORMAT_B8G8R8A8_UNORM; break; case 24: fmt = PIPE_FORMAT_B8G8R8X8_UNORM; break; case 16: fmt = PIPE_FORMAT_B5G6R5_UNORM; break; default: fmt = PIPE_FORMAT_NONE; break; } return (fmt == nconf->color_format); } static boolean fbdev_surface_flush_frontbuffer(struct native_surface *nsurf) { printf("%s %s\n", __FUNCTION__, __FILE__); struct fbdev_surface *fbsurf = fbdev_surface(nsurf); if (!fbsurf->is_current) return TRUE; if(fbsurf->type == FBDEV_SURFACE_TYPE_PIXMAP) //Vivek { return resource_surface_present(fbsurf->rsurf, NATIVE_ATTACHMENT_FRONT_LEFT, fbsurf->pixmap); } else { return resource_surface_present(fbsurf->rsurf, NATIVE_ATTACHMENT_FRONT_LEFT, NULL); } } Regards Vivek</div> <div class="gmail_quote">On Sat, Sep 24, 2011 at 11:08 PM, <<a href="mailto:mesa-dev-request@lists.freedesktop.org">mesa-dev-request@lists.freedesktop.org</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Welcome to the <a href="mailto:mesa-dev@lists.freedesktop.org">mesa-dev@lists.freedesktop.org</a> mailing list!
