From de5ac9e08249449ea932cc6ab4a73ed58429ed66 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Tapani=20P=C3=A4lli?= Date: Mon, 19 Dec 2016 11:47:47 +0200 Subject: [PATCH] egl/dri2: implement query surface hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This makes better guarantee that the values we return are in sync what the underlying drawable currently has. Together with dEQP change bug #98327 this fixes following test: dEQP-EGL.functional.resize.surface_size.grow Signed-off-by: Tapani Pälli Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98327 --- src/egl/drivers/dri2/platform_x11.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) diff --git a/src/egl/drivers/dri2/platform_x11.c b/src/egl/drivers/dri2/platform_x11.c index db7d3b9..0c5d577 100644 --- a/src/egl/drivers/dri2/platform_x11.c +++ b/src/egl/drivers/dri2/platform_x11.c @@ -395,6 +395,34 @@ dri2_x11_destroy_surface(_EGLDriver *drv, _EGLDisplay *disp, _EGLSurface *surf) } /** + * Function utilizes swrastGetDrawableInfo to get surface + * geometry from x server and calls default query surface + * implementation that returns the updated values. + * + * In case of errors we still return values that we currently + * have. + */ +static EGLBoolean +dri2_query_surface(_EGLDriver *drv, _EGLDisplay *dpy, + _EGLSurface *surf, EGLint attribute, + EGLint *value) +{ + struct dri2_egl_display *dri2_dpy = dri2_egl_display(dpy); + struct dri2_egl_surface *dri2_surf = dri2_egl_surface(surf); + int x, y, w = -1, h = -1; + + __DRIdrawable *drawable = dri2_dpy->vtbl->get_dri_drawable(surf); + swrastGetDrawableInfo(drawable, &x, &y, &w, &h, dri2_surf); + + if (w != -1 && h != -1) { + surf->Width = w; + surf->Height = h; + } + + return _eglQuerySurface(drv, dpy, surf, attribute, value); +} + +/** * Process list of buffer received from the server * * Processes the list of buffers received in a reply from the server to either @@ -1113,6 +1141,7 @@ static struct dri2_egl_display_vtbl dri2_x11_swrast_display_vtbl = { .post_sub_buffer = dri2_fallback_post_sub_buffer, .copy_buffers = dri2_x11_copy_buffers, .query_buffer_age = dri2_fallback_query_buffer_age, + .query_surface = dri2_query_surface, .create_wayland_buffer_from_image = dri2_fallback_create_wayland_buffer_from_image, .get_sync_values = dri2_fallback_get_sync_values, .get_dri_drawable = dri2_surface_get_dri_drawable, @@ -1132,6 +1161,7 @@ static struct dri2_egl_display_vtbl dri2_x11_display_vtbl = { .post_sub_buffer = dri2_x11_post_sub_buffer, .copy_buffers = dri2_x11_copy_buffers, .query_buffer_age = dri2_fallback_query_buffer_age, + .query_surface = dri2_query_surface, .create_wayland_buffer_from_image = dri2_fallback_create_wayland_buffer_from_image, .get_sync_values = dri2_x11_get_sync_values, .get_dri_drawable = dri2_surface_get_dri_drawable, -- 2.9.3
