From 0af0c75dc60166d2755537b8499e9e4a1501e4a8 Mon Sep 17 00:00:00 2001 From: Ray Strode Date: Tue, 15 Jan 2019 10:29:55 -0500 Subject: [PATCH 5/9] backends/native: emit gl-video-memory-purged when becoming active The proprietary NVIDIA driver garbles memory on suspend. In order to work around that limitation, mutter needs to refresh all its textures on resuem. This commit lays the way toward doing that by emitting the "gl-video-memory-purged" signal when the compositor becomes active by logind (which happens on VT switch and on resume). --- src/backends/native/meta-backend-native.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/src/backends/native/meta-backend-native.c b/src/backends/native/meta-backend-native.c index 042d96ec6..f87c5a066 100644 --- a/src/backends/native/meta-backend-native.c +++ b/src/backends/native/meta-backend-native.c @@ -618,44 +618,51 @@ meta_activate_session (void) g_warning ("Could not activate session: %s\n", error->message); g_error_free (error); return FALSE; } return TRUE; } void meta_backend_native_pause (MetaBackendNative *native) { MetaBackend *backend = META_BACKEND (native); MetaMonitorManager *monitor_manager = meta_backend_get_monitor_manager (backend); MetaMonitorManagerKms *monitor_manager_kms = META_MONITOR_MANAGER_KMS (monitor_manager); clutter_evdev_release_devices (); clutter_egl_freeze_master_clock (); meta_monitor_manager_kms_pause (monitor_manager_kms); } void meta_backend_native_resume (MetaBackendNative *native) { MetaBackend *backend = META_BACKEND (native); MetaMonitorManager *monitor_manager = meta_backend_get_monitor_manager (backend); MetaMonitorManagerKms *monitor_manager_kms = META_MONITOR_MANAGER_KMS (monitor_manager); + MetaDisplay *display = meta_get_display (); + ClutterBackend *clutter_backend = clutter_get_default_backend (); + CoglContext *cogl_context = + clutter_backend_get_cogl_context (clutter_backend); ClutterActor *stage; MetaIdleMonitor *idle_monitor; + if (cogl_has_feature (cogl_context, COGL_FEATURE_ID_UNSTABLE_TEXTURES)) + g_signal_emit_by_name (display, "gl-video-memory-purged"); + meta_monitor_manager_kms_resume (monitor_manager_kms); clutter_evdev_reclaim_devices (); clutter_egl_thaw_master_clock (); stage = meta_backend_get_stage (backend); clutter_actor_queue_redraw (stage); idle_monitor = meta_backend_get_idle_monitor (backend, 0); meta_idle_monitor_reset_idletime (idle_monitor); } -- 2.18.1
