From 545ac97f9b95e9b5ebd04d2960abb224b5adbe17 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Wed, 17 Feb 2010 23:11:31 +0800 Subject: [PATCH] st/egl: Add dri2InvalidateBuffers. src/glx/dri2.c will call dri2InvalidateBuffers when DRI2_InvalidateBuffers event is received. This fixes a missing symbol error, and paves the way for event-based validation. --- src/gallium/state_trackers/egl/x11/native_dri2.c | 13 ++++- src/gallium/state_trackers/egl/x11/native_x11.c | 2 +- src/gallium/state_trackers/egl/x11/x11_screen.c | 68 ++++++++++++++++++------ src/gallium/state_trackers/egl/x11/x11_screen.h | 10 +++- 4 files changed, 74 insertions(+), 19 deletions(-) diff --git a/src/gallium/state_trackers/egl/x11/native_dri2.c b/src/gallium/state_trackers/egl/x11/native_dri2.c index dbd1a64..feae025 100644 --- a/src/gallium/state_trackers/egl/x11/native_dri2.c +++ b/src/gallium/state_trackers/egl/x11/native_dri2.c @@ -50,6 +50,8 @@ struct dri2_display { struct drm_api *api;
