From 61d8e3282541139cf5bb31e4c42f952a6cc168f8 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Wed, 25 Sep 2013 16:45:22 +0100 Subject: drm: Add a STEREO_3D capability to the SET_CLIENT_CAP ioctl MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This capability allows user space to control the delivery of modes with the 3D flags set. This is to not play games with current user space users not knowing anything about stereo 3D flags and that could try to set a mode with one or several of those bits set. So, the plan is to remove the stereo modes from the list of modes we give to DRM clients by default, and let them through if we are being told otherwise. stereo_allowed is bound to the drm_file structure to make it a per-client setting, not a global one. v2: Replace clearing 3D flags by discarding the stereo modes now that they are regular modes. v3: SET_CAP -> SET_CLIENT_CAP rename (Chris Wilson) Reviewed-by: Ville Syrjälä Signed-off-by: Damien Lespiau Acked-by: Dave Airlie Signed-off-by: Daniel Vetter --- include/drm/drmP.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/drm') diff --git a/include/drm/drmP.h b/include/drm/drmP.h index dbc86b06a724..c65f496ad6b6 100644 --- a/include/drm/drmP.h +++ b/include/drm/drmP.h @@ -433,6 +433,9 @@ struct drm_file { struct drm_master *master; /* master this node is currently associated with N.B. not always minor->master */ + /* true when the client has asked us to expose stereo 3D mode flags */ + bool stereo_allowed; + /** * fbs - List of framebuffers associated with this file. * -- cgit v1.2.3
