From 79aa1d54746f33c33ffbf98fb96ccbf88c3cb390 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 17 Apr 2007 18:16:38 +1000 Subject: another large overhaul of interactions with userspace... We need to keep a list of user created fbs to nuke on master exit. We also need to use the bo properly. --- linux-core/drmP.h | 2 ++ linux-core/drm_bo_move.c | 1 + linux-core/drm_crtc.c | 33 +++++++++++++++++++++++++-------- linux-core/drm_crtc.h | 1 + linux-core/drm_fb.c | 7 ++----- linux-core/drm_fops.c | 4 +++- linux-core/drm_objects.h | 5 +++++ linux-core/drm_stub.c | 13 +++++++------ shared-core/i915_dma.c | 12 ++++++++++++ shared-core/i915_drv.h | 1 - shared-core/i915_init.c | 35 ++++++++++++++++++++++------------- 11 files changed, 80 insertions(+), 34 deletions(-) diff --git a/linux-core/drmP.h b/linux-core/drmP.h index 0d0ec992..326565cb 100644 --- a/linux-core/drmP.h +++ b/linux-core/drmP.h @@ -431,6 +431,8 @@ typedef struct drm_file { drm_open_hash_t refd_object_hash[_DRM_NO_REF_TYPES];
