From 1a6c95ef711fce807659ab5e4fe480d65ac233b6 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 5 Dec 2007 16:03:05 +1000 Subject: arrgggh.. make all ioctl structs 32/64-bit compatible hopefully. This also starts to add blob property support. someone needs to check this work for other things like ppc/x86 alignment diffs --- linux-core/drm_crtc.c | 163 ++++++++++++++++++++++++++++++++++++------------- linux-core/drm_crtc.h | 23 +++++-- linux-core/intel_crt.c | 2 + 3 files changed, 140 insertions(+), 48 deletions(-) (limited to 'linux-core') diff --git a/linux-core/drm_crtc.c b/linux-core/drm_crtc.c index 26aa5206..c2680319 100644 --- a/linux-core/drm_crtc.c +++ b/linux-core/drm_crtc.c @@ -722,7 +722,11 @@ void drm_mode_config_init(struct drm_device *dev) INIT_LIST_HEAD(&dev->mode_config.crtc_list);
