drm: add DRM_CAPs for cursor size

2014-02-18T18:41:01Z

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 Reviewed-by: Rob Clark

drm/bufs: remove handling of _DRM_GEM mappings

2013-12-18T01:08:42Z

Gone with the new gem vma offset manager from David. We can also ditch the uapi header definition from the enum since userspace never used this. It ended up in there purely for historical reasons (for reusing the old drm mmap code essentially), not because userspace ever needed it.

drm: Add a STEREO_3D capability to the SET_CLIENT_CAP ioctl

2013-10-01T05:45:27Z

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

drm: Add a SET_CLIENT_CAP ioctl

2013-10-01T05:45:26Z

This ioctl can be used to turn some knobs in a DRM driver. The client can ask the DRM core for an alternate view of the reality: it can be useful to be able to instruct the core that the DRM client can handle new functionnality that would otherwise break current ABI. v2: Rename to ioctl from SET_CAP to SET_CLIENT_CAP (Chris Wilson) Reviewed-by: Ville Syrjälä Signed-off-by: Damien Lespiau Acked-by: Dave Airlie Signed-off-by: Daniel Vetter

drm: Move the GET_CAP macros next to the corresponding ioctl structure

2013-10-01T05:45:25Z

It's a tiny bit more logical to find the different capabilities you can use with the GET_CAP ioctl next to the structure rather than putting them at the end of the file. v2: Tab align the litterals (David Herrmann) v3: Make it clearer that DRM_PRIME_CAP_EXPORT/IMPORT are flags of DRM_CAP_PRIME. v4: Rebase on top of latest bits (DRM_CAP_ASYNC_PAGE_FLIP was introduced) Reviewed-by: David Herrmann (for v2) Signed-off-by: Damien Lespiau Acked-by: Dave Airlie Signed-off-by: Daniel Vetter

drm/gem: convert to new unified vma manager

2013-07-25T10:47:06Z

Use the new vma manager instead of the old hashtable. Also convert all drivers to use the new convenience helpers. This drops all the (map_list.hash.key << PAGE_SHIFT) non-sense. Locking and access-management is exactly the same as before with an additional lock inside of the vma-manager, which strictly wouldn't be needed for gem. v2: - rebase on drm-next - init nodes via drm_vma_node_reset() in drm_gem.c v3: - fix tegra v4: - remove duplicate if (drm_vma_node_has_offset()) checks - inline now trivial drm_vma_node_offset_addr() calls v5: - skip node-reset on gem-init due to kzalloc() - do not allow mapping gem-objects with offsets (backwards compat) - remove unneccessary casts Cc: Inki Dae Cc: Rob Clark Cc: Dave Airlie Cc: Thierry Reding Signed-off-by: David Herrmann Acked-by: Patrik Jakobsson Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie

drm: add hotspot support for cursors.

2013-06-27T23:13:39Z

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.

drm: Kill user_modes list and the associated ioctls

2013-04-30T00:03:07Z

There is no way to use modes added to the user_modes list. We never look at the contents of said list in the kernel, and the only operations userspace can do are attach and detach. So the only "benefit" of this interface is wasting kernel memory. Fortunately it seems no real user space application ever used these ioctls. So just kill them. Also remove the prototypes for the non-existing drm_mode_addmode_ioctl() and drm_mode_rmmode_ioctl() functions. v2: Use drm_noop instead of completely removing the ioctls Signed-off-by: Ville Syrjälä Signed-off-by: Dave Airlie

drm.h: Fix DRM compilation with bare-metal toolchain.

2013-04-16T03:15:26Z

An ifdef in drm.h expects to be compiled with full-fledged Linux toolchain, but it's common to compile kernel with just bare-metal toolchain which doesn't define __linux__. So, also add __KERNEL__ check. [nm@ti.com: port forward to 3.9-rc6 and post to dri devel for feedback as RFC] Signed-off-by: Paul Sokolovsky Signed-off-by: Dave Airlie
