From: Marc-André Lureau <marcandre.lur...@redhat.com> eglMakeCurrent() returns 1/EGL_TRUE on success. This is not what the callback expects, where 0 indicates success.
While at it, print the EGL error to ease debugging. As with virgl_renderer_callbacks, the return value is now checked since version >= 4: https://gitlab.freedesktop.org/virgl/virglrenderer/-/commit/7f09e6bf0c6ceea6727bd0049781256a28cab0e5 Signed-off-by: Marc-André Lureau <marcandre.lur...@redhat.com> --- ui/egl-context.c | 10 ++++++++-- ui/gtk-egl.c | 9 +++++++-- 2 files changed, 15 insertions(+), 4 deletions(-) diff --git a/ui/egl-context.c b/ui/egl-context.c index eb5f520fc4..9e0df466f3 100644 --- a/ui/egl-context.c +++ b/ui/egl-context.c @@ -1,4 +1,5 @@ #include "qemu/osdep.h" +#include "qemu/error-report.h" #include "ui/egl-context.h" QEMUGLContext qemu_egl_create_context(DisplayGLCtx *dgc, @@ -32,6 +33,11 @@ void qemu_egl_destroy_context(DisplayGLCtx *dgc, QEMUGLContext ctx) int qemu_egl_make_context_current(DisplayGLCtx *dgc, QEMUGLContext ctx) { - return eglMakeCurrent(qemu_egl_display, - EGL_NO_SURFACE, EGL_NO_SURFACE, ctx); + if (!eglMakeCurrent(qemu_egl_display, + EGL_NO_SURFACE, EGL_NO_SURFACE, ctx)) { + error_report("egl: eglMakeCurrent failed: %s", qemu_egl_get_error_string()); + return -1; + } + + return 0; } diff --git a/ui/gtk-egl.c b/ui/gtk-egl.c index 19130041bc..f8b5901ce9 100644 --- a/ui/gtk-egl.c +++ b/ui/gtk-egl.c @@ -368,6 +368,11 @@ int gd_egl_make_current(DisplayGLCtx *dgc, { VirtualConsole *vc = container_of(dgc, VirtualConsole, gfx.dgc); - return eglMakeCurrent(qemu_egl_display, vc->gfx.esurface, - vc->gfx.esurface, ctx); + if (!eglMakeCurrent(qemu_egl_display, vc->gfx.esurface, + vc->gfx.esurface, ctx)) { + error_report("egl: eglMakeCurrent failed: %s", qemu_egl_get_error_string()); + return -1; + } + + return 0; } -- 2.40.1
