Hello,
I did build upstream XWayland w/ EGLStreams support with the following patch as GL_OES_EGL_image isn’t exposed for desktop OpenGL on L4T:
diff --git a/hw/xwayland/xwayland-glamor-eglstream.c b/hw/xwayland/xwayland-glamor-eglstream.c
index 8d18caaf5..10ab2919c 100644

+++ b/hw/xwayland/xwayland-glamor-eglstream.c

xwl_eglstream_init_shaders(xwl_screen);
- if (epoxy_has_gl_extension("GL_OES_EGL_image")) {
if (dri3_screen_init(xwl_screen->screen, &xwl_dri3_info))
xwl_screen->glvnd_vendor = "nvidia";
else
ErrorF("DRI3 initialization failed. Performance will be affected.\n");
- } else {
- ErrorF("Driver lacks GL_OES_EGL_image, performance will be affected.\n");
- }
return TRUE;
error:
And then starting a self-compiled Xwayland w/ that patch applied with:
./build/hw/xwayland/Xwayland :4 -eglstream -rootless
Trying to use glxinfo then results in:
$ DISPLAY=:4 glxinfo
name of display: :4

and for Vulkan:

(note that the Weston in nvidia-l4t-weston does not expose wl_drm, so I didn’t try with using the DRM backend instead of EGLStreams)
Can XWayland compatibility w/ GPU acceleration be made available in the L4T 32.x series please, like it was for desktop GPUs?
And Vulkan support for Wayland if not available (was not able to test it)?
Thank you,
