Hi,
I've been trying to get cog to run in DRM mode on an orange pi5+ board without any luck.

Nothing is rendered inside cog window using DRM platform (or x11 for that matter):

Environment:

HW: Orange Pi 5+

#cat /etc/os-release PRETTY_NAME="Orange Pi 1.0.6 Bullseye" NAME="Debian GNU/Linux" VERSION_ID="11" VERSION="11 (bullseye)" VERSION_CODENAME=bullseye

./kmscube

More Observation(s):

The .export_fdo_egl_image callback for DRM gles platform is not being called at any point.

static const struct wpe_view_backend_exportable_fdo_egl_client client = {
.export_fdo_egl_image = cog_drm_gles_renderer_handle_egl_image,
};

I’ve found this structure below in the code that seems relevent.
From the source file /home/orangepi/repos/wpebackend-fdo-1.14.2/src/ws.cpp

static const struct wl_surface_interface s_surfaceInterface = {
// destroy
[](struct wl_client*, struct wl_resource*) { },
// attach
// !!!! Not being called !!!!
[](struct wl_client*, struct wl_resource* surfaceResource, struct wl_resource* bufferResource, int32_t, int32_t)
{

   g_message("wl_surface_interface.attach ");
   auto& surface = *static_cast<Surface*>(wl_resource_get_user_data(surfaceResource));
   Instance::singleton().impl().surfaceAttach(surface, bufferResource);

},
// !!!! damage !!!
[](struct wl_client*, struct wl_resource*, int32_t, int32_t, int32_t, int32_t) { g_message("wl_surface_interface.damage ");},
// frame
// Called
[](struct wl_client* client, struct wl_resource* surfaceResource, uint32_t callback)
{
g_message("wl_surface_interface.frame 1/4");
auto& surface = static_cast<Surface>(wl_resource_get_user_data(surfaceResource));
if (!surface.apiClient)
return;

   g_message("wl_surface_interface.frame 2/4");
   struct wl_resource* callbackResource = wl_resource_create(client, &wl_callback_interface, 1, callback);
   if (!callbackResource) {
       wl_resource_post_no_memory(surfaceResource);
       return;
   }


   g_message("wl_surface_interface.frame 3/4");
   wl_resource_set_implementation(callbackResource, nullptr, nullptr,
       [](struct wl_resource* resource) {
           wl_list_remove(wl_resource_get_link(resource));
       });
   g_message("wl_surface_interface.frame 4/4");
   surface.addFrameCallback(callbackResource);

},
// set_opaque_region
[](struct wl_client*, struct wl_resource*, struct wl_resource*) { g_message("wl_surface_interface.set_opaque_region ");},
// set_input_region
[](struct wl_client*, struct wl_resource*, struct wl_resource*) {g_message("wl_surface_interface.set_input_region ");},
// commit
// !!! not being called !!!
[](struct wl_client*, struct wl_resource* surfaceResource)
{

   g_message("wl_surface_interface.commit ");       
   auto& surface = *static_cast<Surface*>(wl_resource_get_user_data(surfaceResource));
   surface.commit();
   WS::Instance::singleton().impl().surfaceCommit(surface);

},
// set_buffer_transform
[](struct wl_client*, struct wl_resource*, int32_t) { },
// set_buffer_scale
[](struct wl_client*, struct wl_resource*, int32_t) { },
#if (WAYLAND_VERSION_MAJOR > 1) || (WAYLAND_VERSION_MAJOR == 1 && WAYLAND_VERSION_MINOR >= 10)
// damage_buffer
// not being called
[](struct wl_client*, struct wl_resource*, int32_t, int32_t, int32_t, int32_t) { g_message("wl_surface_interface.damage_buffer");},
#endif
};

I have commented above where the functions are not being called. It seems they should ?!?
I’m not able to find where or what they should be invoked by.

It just seems like something very simple is wrong/missing.

Go for mainline/mesa/panfrost instead. I also failed to get it working on libmali, but worked like a charm on panfrost

Thanks,
What distro did you use and did you have to build it from scratch ?

I'm using yocto, just master branch
