* drm/mode: Add user blob-creation ioctlDaniel Stone2015-05-221-0/+2
| | | | | | | | | | | | | | | Add an ioctl which allows users to create blob properties from supplied data. Currently this only supports modes, creating a drm_display_mode from the userspace drm_mode_modeinfo. v2: Removed size/type checks. Rebased on new patches to allow error propagation from create_blob, as well as avoiding double-allocation.

* drm: add support for tiled/compressed/etc modifier in addfb2Rob Clark2015-02-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In DRM/KMS we are lacking a good way to deal with tiled/compressed formats. Especially in the case of dmabuf/prime buffer sharing, where we cannot always rely on under-the-hood flags passed to driver specific gem-create ioctl to pass around these extra flags. The proposal is to add a per-plane format modifier. This allows to, if necessary, use different tiling patters for sub-sampled planes, etc. The format modifiers are added at the end of the ioctl struct, so for legacy userspace it will be zero padded. v1: original v1.5: increase modifier to 64b v2: Incorporate review comments from the big thread, plus a few more. - Add a getcap so that userspace doesn't have to jump through hoops. - Allow modifiers only when a flag is set. That way drivers know when they're dealing with old userspace and need to fish out e.g. tiling from other information. - After rolling out checks for ->modifier to all drivers I've decided that this is way too fragile and needs an explicit opt-in flag. So do that instead. - Add a define (just for documentation really) for the "NONE" modifier. Imo we don't need to add mask #defines since drivers really should only do exact matches against values defined with fourcc_mod_code. - Drop the Samsung tiling modifier on Rob's request since he's not yet sure whether that one is accurate. v3: - Also add a new ->modifier[] array to struct drm_framebuffer and fill it in drm_helper_mode_fill_fb_struct. Requested by Tvrkto Uruslin. - Remove TODO in comment and add code comment that modifiers should be properly documented, requested by Rob.

* drm: Atomic modeset ioctlRob Clark2015-01-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | The atomic modeset ioctl can be used to push any number of new values for object properties. The driver can then check the full device configuration as single unit, and try to apply the changes atomically. The ioctl simply takes a list of object IDs and property IDs and their values. Originally based on a patch from Ville Syrjälä, although it has mutated (mutilated?) enough since then that you probably shouldn't blame it on him ;-) The atomic support is hidden behind the DRM_CLIENT_CAP_ATOMIC cap (to protect legacy userspace) and drm.atomic module param (for now). v2: Check for file_priv->atomic to make sure we only allow userspace in-the-know to use atomic.

* drm: add atomic propertiesRob Clark2015-01-051-0/+7
| | | | | | | | | | | | | | | | | | | | | Once a driver is using atomic helpers for modeset, the next step is to switch over to atomic properties. To do this, make sure that any modeset objects have their ->atomic_{get,set}_property() vfuncs suitably populated if they have custom properties (you did already remember to plug in atomic-helper func for the legacy ->set_property() vfuncs, right?), and then set DRIVER_ATOMIC bit in driver_features flag. A new cap is introduced, DRM_CLIENT_CAP_ATOMIC, for the purposes of shielding legacy userspace from atomic properties. Mostly for the benefit of legacy DDX drivers that do silly things like getting/setting each property at startup (since some of the new atomic properties will be able to trigger modeset).

|/ | | | | | | | | | | | | | | | | | | | | | Earlier this week, there was a bit of confusion about those new capabilities, to the point I think it's better to document the intention and API contract. The comment documents the current situation: - the radeon driver returns the only valid size for the hw - i915 returns the maximun cursor size - other drivers fall back to returning 64x64 The common contract is to return a valid cursor size.

* drm: add DRM_CAPs for cursor sizeAlex Deucher2014-02-181-0/+2
| | | | | | | | | | | | | Some hardware may not support standard 64x64 cursors. Add a drm cap to query the cursor size from the kernel. Some examples include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32). This allows things like device specific ddxes to remove asics specific logic and also allows xf86-video-modesetting to work properly with hw cursors on this hardware. Default to 64 if the driver doesn't specify a size. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Rob Clark <robdclark@gmail.com>

* drm: Add a STEREO_3D capability to the SET_CLIENT_CAP ioctlDamien Lespiau2013-10-011-0/+9
| | | | | | | | | | | | | | | | | | | | | | | 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 <ville.syrjala@linux.intel.com> Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

* drm: add hotspot support for cursors.Dave Airlie2013-06-281-0/+1
| | | | | | | | | | | | | | | So it looks like for virtual hw cursors on QXL we need to inform the "hw" device what the cursor hotspot parameters are. This makes sense if you think the host has to draw the cursor and interpret clicks from it. However the current modesetting interface doesn't support passing the hotspot information from userspace. This implements a new cursor ioctl, that takes the hotspot info as well, userspace can try calling the new interface and if it gets -ENOSYS it means its on an older kernel and can just fallback.
