2022-03-14ui/console: egl-headless is compatible with non-gl listenersMarc-André Lureau1-0/+8
Fix a regression introduced by commit 5e79d516e ("ui: split the GL context in a different object"). Reported-by: Akihiko Odaki <akihiko.odaki@gmail.com> Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Acked-by: Gerd Hoffmann <kraxel@redhat.com>
2022-03-14ui/console: move dcl compatiblity check to a callbackMarc-André Lureau1-1/+8
As expected from the "compatible_dcl" comment, a simple comparison of ops isn't enough. The following patch will fix a regression introduced by this limited check by extending the compatibility callback for egl-headless. For now, this patch simply replaces the the "compatible_dcl" ops pointer with a "dpy_gl_ctx_is_compatible_ctx" callback.

2021-07-26ui/egl-headless: Remove a check for CONFIG_OPENGLAkihiko Odaki1-2/+0

2019-09-17ui/egl: fix framebuffer readsGerd Hoffmann1-3/+1
Fix egl_fb_read() to use the (destination) surface size instead of the (source) framebuffer source for glReadPixels. Pass the DisplaySurface instead of the pixeldata pointer to egl_fb_read() to make this possible. With that in place framebuffer reads work fine even if the surface and framebuffer sizes don't match, so we can remove the guest-triggerable asserts in egl_scanout_flush().

2019-01-10egl-headless: add egl_create_contextGerd Hoffmann1-1/+9
We must set the correct context (via eglMakeCurrent) before calling qemu_egl_create_context, so we need a thin wrapper and can't hook qemu_egl_create_context directly as ->dpy_gl_ctx_create callback.

2018-11-16ui: Allow specifying 'rendernode' display option for egl-headlessErik Skultety1-1/+1
As libvirt can't predict which rendernode QEMU would pick, it won't adjust the permissions on the device, hence QEMU getting "Permission denied" when opening the DRI device. Therefore, enable 'rendernode' option for egl-headless display type.

2018-06-26Add gles support to egl-helpers, wire up in egl-headless and gtk.Gerd Hoffmann1-1/+2
Add support for OpenGL ES to egl-helpers. Wire up the new option for egl-headless and gtk UIs. egl-headless actually works fine. gtk hits a not-yet implemented code path in libEGL when trying to use gles mode: libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering. (This is mesa 17.2.3).

2017-05-12opengl: add egl-headless displayGerd Hoffmann1-0/+158
Add egl-headless user interface. It doesn't provide a real user interface, it only provides opengl support using drm render nodes. It will copy back the bits rendered by the guest using virgl back to a DisplaySurface and kick the usual display update code paths, so spice and vnc and screendump can pick it up. Use it this way: qemu -display egl-headless -vnc $display qemu -display egl-headless -spice gl=off,$args Note that you should prefer native spice opengl support (-spice gl=on) if possible because that delivers better performance.
