drm/atomic-helper: Export framebuffer_changed()

2016-01-20T00:55:43+00:00

The Rockchip driver cannot use drm_atomic_helper_wait_for_vblanks()
because it has hardware counters for neither vblanks nor scanlines.

In order to simplify re-implementing the functionality for this driver,
export the framebuffer_changed() helper so it can be reused.

Merge tag 'topic/drm-misc-2016-01-17' of git://anongit.freedesktop.org/drm-intel into drm-next

2016-01-17T21:01:16+00:00

Since your main drm-next pull isn't out of the door yet I figured I might
as well flush out drm-misc instead of delaying for 4.6. It's really just
random stuff all over, biggest thing probably connector_mask tracking from
Maarten.

drm/ttm: add ttm_bo_move_to_lru_tail function v2

2016-01-13T17:21:21+00:00

This allows the drivers to move a BO to the end of the LRU
without removing and adding it again.

v2: Make it more robust, handle pinned and swapable BOs as well.

drm/atomic: Remove drm_atomic_connectors_for_crtc.

2016-01-06T15:37:39+00:00

Now that connector_mask is reliable there's no need for this
function any more.

drm/docs: more leftovers from the big vtable documentation pile

2016-01-05T15:21:35+00:00

Another pile of vfuncs from the old gpu.tmpl xml documentation that
I've forgotten to delete. I spotted a few more things to
clarify/extend in the new kerneldoc while going through this once
more.

v2: Spelling fixes (Thierry).

v3: More spelling fixes and use Thierry's proposal to clarify why
drivers need to validate modes both in ->mode_fixup and ->mode_valid.

drm/atomic-helper: Reject legacy flips on a disabled pipe

2016-01-05T09:07:51+00:00

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.

drm/atomic: add connector mask to drm_crtc_state.

2016-01-05T08:43:33+00:00

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.

drm/dp/mst: always send reply for UP request

We should always send reply for UP request in order
to make downstream device clean-up resources appropriately.

Issue was that reply for UP request was sent only once.
