Gustavo Padovan 6d6003c4b6 drm/fence: add fence timeline to drm_crtc
Create one timeline context for each CRTC to be able to handle out-fences
and signal them. It adds a few members to struct drm_crtc: fence_context,
where we store the context we get from fence_context_alloc(), the
fence seqno and the fence lock, that we pass in fence_init() to be
used by the fence.

v2: Comment by Daniel Stone:
	- add BUG_ON() to fence_to_crtc() macro

v3: Comment by Ville Syrjälä
	- Use more meaningful name as crtc timeline name

v4: Comments by Brian Starkey
	- Use even more meaninful name for the crtc timeline
	- add doc for timeline_name
    Comment by Daniel Vetter
	- use in-line style for comments

    - rebase after fence -> dma_fence rename

v5: Comment by Daniel Vetter
	- Add doc for drm_crtc_fence_ops

v6: Comment by Chris Wilson
	- Move fence_to_crtc to drm_crtc.c
	- Move export of drm_crtc_fence_ops to drm_crtc_internal.h

    - rebase against latest drm-misc

Chris Wilson f54d186700 dma-buf: Rename struct fence to dma_fence
I plan to usurp the short name of struct fence for a core kernel struct,
and so I need to rename the specialised fence/timeline for DMA
operations to make room.

A consensus was reached in
https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html
that making clear this fence applies to DMA operations was a good thing.
Since then the patch has grown a bit as usage increases, so hopefully it
remains a good thing!

(v2...: rebase, rerun spatch)
v3: Compile on msm, spotted a manual fixup that I broke.
v4: Try again for msm, sorry Daniel

Tomeu Vizoso 9edbf1fa60 drm: Add API for capturing frame CRCs
Adds files and directories to debugfs for controlling and reading frame
CRCs, per CRTC:

dri/0/crtc-0/crc
dri/0/crtc-0/crc/control
dri/0/crtc-0/crc/data

Drivers can implement the set_crc_source callback() in drm_crtc_funcs to
start and stop generating frame CRCs and can add entries to the output
by calling drm_crtc_add_crc_entry.

v2:
    - Lots of good fixes suggested by Thierry.
    - Added documentation.
    - Changed the debugfs layout.
    - Moved to allocate the entries circular queue once when frame
      generation gets enabled for the first time.
v3:
    - Use the control file just to select the source, and start and stop
      capture when the data file is opened and closed, respectively.
    - Make variable the number of CRC values per entry, per source.
    - Allocate entries queue each time we start capturing as now there
      isn't a fixed number of CRC values per entry.
    - Store the frame counter in the data file as a 8-digit hex number.
    - For sources that cannot provide useful frame numbers, place
      XXXXXXXX in the frame field.

v4:
    - Build only if CONFIG_DEBUG_FS is enabled.
    - Use memdup_user_nul.
    - Consolidate calculation of the size of an entry in a helper.
    - Add 0x prefix to hex numbers in the data file.
    - Remove unnecessary snprintf and strlen usage in read callback.

v5:
    - Made the crcs array in drm_crtc_crc_entry fixed-size
    - Lots of other smaller improvements suggested by Emil Velikov

v7:
    - Move definition of drm_debugfs_crtc_crc_add to drm_internal.h

v8:
    - Call debugfs_remove_recursive when we fail to create the minor
      device

v9:
    - Register the debugfs directory for a crtc from
      drm_crtc_register_all()

v10:
    - Don't let debugfs failures interrupt CRTC registration (Emil
      Velikov)

v11:
    - Remove extra brace that broke compilation. Sorry!

It's not that obvious how a driver can all race the atomic commit with

Daniel Vetter 949619f32e drm: Extract drm_mode_object.[hc]
Just for the struct drm_mode_object base class. The header file was
already partially extracted to help untangle the include loops.

v2:
- Also move the generic get/set property ioctls. At first this seemed
  like a bad idea since it requires making drm_mode_crtc_set_obj_prop
  non-static. But eventually that will get split away too (like
  the connector version already is) for both crtc and planes. Hence I
  reconsidered.

- drm_mode_object.[hc] instead of drm_modeset.[hc], which requires
  renaming the drm_modeset.h header I already started building up.
  This is more consistent (matches the name of the main structure),
  and I want to be able to use drm_modeset.[hc] for the basic modeset
  init/cleanup functionality like drm_mode_config_init.

Andrea Merello cf3bef95e1 drm/bridge: introduce bridge detaching mechanism
Up to now, once a bridge has been attached to a DRM device, it cannot
be undone.

In particular you couldn't rmmod/insmod a DRM driver that uses a bridge,
because the bridge would remain bound to the first (dead) driver instance.

This patch fixes this by introducing drm_encoder_detach() and a ->detach
callback in drm_bridge_funcs for the bridge to be notified about detaches.

It's DRM/KMS driver responsibility to call drm_encoder_detach().

While adding the bridge detach callback, with its kerneldoc, I also added
kerneldoc for attach callback.

Few other kerneldocs fixes around there are included.

a multitude of competing ways. Might be best to consolidate it all and
use MEDIA_BUS_FMT_ also for the hdmi color formats and high color
modes.

Also move all the display_info related functions into drm_connector.c
(there's only one) to group it all together. I did decided against
also moving the edid related display info functions, they seem to fit
better in drm_edid.c. Instead sprinkle a few cross references around.
While at that reduce the kerneldoc for static functions, there's not
point in documenting internals with that much detail really.

v2: Fix typo and move misplaced hunk (Sean).

Daniel Vetter 5221719517 drm: Extract drm_connector.[hc]
Pulls in quite a lot of connector related structures (cmdline mode,
force/status enums, display info), but I think that all makes perfect
sense.

Also had to move a few more core kms object stuff into drm_modeset.h.

And as a first cleanup remove the kerneldoc for the 2 connector IOCTL
- DRM core docs are aimed at drivers, no point documenting internal in
excruciating detail.

v2: And also pull in all the connector property code.

It was added way back together with the dirty_fb ioctl, but neither
generic xfree86-modesetting nor the vmware driver use it. Everyone is

Marek Szyprowski 44d1240d00 drm: add generic zpos property
version 8:
- move drm_blend.o from drm-y to drm_kms_helper-y to avoid
  EXPORT_SYMBOL(drm_atomic_helper_normalize_zpos)
- remove dead function declarations in drm_crtc.h

version 7:
- remove useless EXPORT_SYMBOL()
- better z-order wording in Documentation

version 6:
- add zpos in gpu documentation file
- merge Ville patch about zpos initial value and API improvement.
  I have split Ville patch between zpos core and drivers

version 5:
- remove zpos range check and comeback to 0 to N-1
  normalization algorithm

version 4:
- make sure that normalized zpos value is stay
  in the defined property range and warn user if not

This patch adds support for generic plane's zpos property property with
well-defined semantics:
- added zpos properties to plane and plane state structures
- added helpers for normalizing zpos properties of given set of planes
- well defined semantics: planes are sorted by zpos values and then plane
  id value if zpos equals

Normalized zpos values are calculated automatically when generic
muttable zpos property has been initialized. Drivers can simply use
plane_state->normalized_zpos in their atomic_check and/or plane_update
callbacks without any additional calls to DRM core.

Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>

Compare to Marek's original patch zpos property is now specific to each
plane and no more to the core.
Normalize function take care of the range of per plane defined range
before set normalized_zpos.

Daniel Vetter 9f2a7950e7 drm/atomic-helper: nonblocking commit support
Design ideas:

- split up the actual commit into different phases, and have
  completions for each of them. This will be useful for the future
  when we want to interleave phases much more aggressively, for e.g.
  queue depth > 1. For not it's just a minimal optimization compared
  to current common nonblocking implementation patterns from drivers,
  which all stall for the entire commit to complete, including vblank
  waits and cleanups.

- Extract a separate atomic_commit_hw hook since that's the part most
  drivers will need to overwrite, hopefully allowing even more shared
  code.

- Enforce EBUSY seamntics by attaching one of the completions to the
  flip_done vblank event. Side benefit of forcing atomic drivers using
  these helpers to implement event handlign at least semi-correct. I'm
  evil that way ;-)

- Ridiculously modular, as usual.

- The main tracking unit for a commit stays struct drm_atomic_state,
  and the ownership rules for that are unchanged. Ownership still
  gets transferred to the driver (and subsequently to the worker) on
  successful commits. What is added is a small, per-crtc, refcounted
  structure to track pending commits called struct drm_crtc_commit.
  No actual state is attached to that though, it's purely for ordering
  and waiting.

- Dependencies are implicitly handled by assuming that any CRTC part
  of &drm_atomic_state is a dependency, and that the current commit
  must wait for any commits to complete on those CRTC. This way
  drivers can easily add more depencies using
  drm_atomic_get_crtc_state(), which is very natural since in most
  case a dependency exists iff there's some bit of state that needs to
  be cross checked.

  Removing depencies is not possible, drivers simply need to be
  careful to not include every CRTC in a commit if that's not
  necessary. Which is a good idea anyway, since that also avoids
  ww_mutex lock contention.

- Queue depth > 1 sees some prep work in this patch by adding a stall
  paramater to drm_atomic_helper_swap_states(). To be able to push
  commits entirely free-standing and in a deeper queue through the
  back-end the driver must not access any obj->state pointers. This
  means we need to track the old state in drm_atomic_state (much
  easier with the consolidated arrays), and pass them all explicitly
  to driver backends (this will be serious amounts of churn).

  Once that's done stall can be set to false in swap_states.

v2: Dont ask for flip_done signalling when the CRTC is off and stays
off: Drivers don't handle events in that case. Instead complete right
away. This way future commits don't need to have special-case logic,
but can keep blocking for the flip_done completion.

v3: Tons of fixes:
- Stall for preceeding commit for real, not the current one by
  accident.
- Add WARN_ON in case drivers don't fire the drm event.
- Don't double-free drm events.

v4: Make legacy cursor not stall.

v5: Extend the helper hook to cover the entire commit tail. Some
drivers need special code for cleanup and vblank waiting, this makes
it a bit more useful. Inspired by the rockchip driver.

v6: Add WARN_ON to catch drivers who forget to send out the
drm event.

v7: Fixup the stalls in swap_state for real!!

v8:
- Fixup trailing whitespace, spotted by Maarten.
- Actually wait for flip_done in cleanup_done, like the comment says
  we should do. Thanks a lot for Tomeu for helping with debugging this
  on.

v9: Now with awesome kerneldoc!

v10: Split out drm_crtc_commit tracking infrastructure.

v:
- Add missing static (Gustavo).
- Split out the sync functions, only do the actual nonblocking
  logic in this patch (Maarten).
