2016-01-05drm/atomic-helper: Reject legacy flips on a disabled pipeDaniel Vetter2-0/+25
We want this for consistency with existing page_flip semantics. Since this spurred quite a discussion on IRC also document why we reject event generation when the pipe is off: It's not that it's hard to implement, but userspace has a track recording which proves that it's way too easy to accidentally abuse and cause havoc. We want to make sure userspace doesn't get away with that. v2: Somehow thought we do reject events already, but that code only existed in my imagination ... Also suggestions from Thierry.

2016-01-05drm/atomic: add connector mask to drm_crtc_state.Maarten Lankhorst1-0/+11
It can be useful to iterate over connectors without grabbing connection_mutex. It can also be used to see how many connectors are on a crtc without iterating over the list.

2016-01-05drm: Use a normal idr allocation for the obj->nameChris Wilson1-3/+1
Unlike the handle, the name table uses a sleeping mutex rather than a spinlock. The allocation is in a normal context, and we can use the simpler sleeping gfp_t, rather than have to take from the atomic reserves.

2016-01-05drm: Balance error path for GEM handle allocationChris Wilson1-12/+17
The current error path for failure when establishing a handle for a GEM object is unbalance, e.g. we call object_close() without calling first object_open().
