drm_mode_create_lease Creates a lease for a list of drm mode objects, returning an fd for the new drm_master and a 64-bit identifier for the lessee drm_mode_list_lesees List the identifiers of the lessees for a master file drm_mode_get_lease List the leased objects for a master file drm_mode_revoke_lease Erase the set of objects managed by a lease. This should suffice to at least create and query leases. Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>: * query ioctls only query the master associated with the provided file. * 'mask_lease' value has been removed * change ioctl has been removed. Changes for v3 suggested in part by Dave Airlie <airlied@gmail.com> * Add revoke ioctl. Changes for v4 suggested by Dave Airlie <airlied@gmail.com> * Expand on the comment about the magic use of &drm_lease_idr_object * Pad lease ioctl structures to align on 64-bit boundaries Changes for v5 suggested by Dave Airlie <airlied@gmail.com> * Check for non-negative object_id in create_lease to avoid debug output from the kernel. Changes for v6 provided by Dave Airlie <airlied@gmail.com> * For non-universal planes add primary/cursor planes to lease If we aren't exposing universal planes to this userspace client, and it requests a lease on a crtc, we should implicitly export the primary and cursor planes for the crtc. If the lessee doesn't request universal planes, it will just see the crtc, but if it does request them it will then see the plane objects as well. This also moves the object look ups earlier as a side effect, so we'd exit the ioctl quicker for non-existant objects. * Restrict leases to crtc/connector/planes. This only allows leasing for objects we wish to allow. Changes for v7 provided by Dave Airlie <airlied@gmail.com> * Check pad args are 0 * Check create flags and object count are valid. * Check return from fd allocation * Refactor lease idr setup and add some simple validation * Use idr_mutex uniformly (Keith) Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com> |
