Ben Widawsky e6fc3b6855 drm: Plumb modifiers through plane init
This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.

This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.

v2: A minor addition from Daniel

v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)

v4: Minor comment adjustments (Liviu)

v5: Some new platforms added due to rebase

v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)

Rob Herring 4bf99144d2 drm: Convert to using %pOF instead of full_name
Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Daniel Vetter e1923ab3d0 drm/<drivers>: Drop fbdev info flags
- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed
  the entire panic handling code in our fbdev emulation. We might
  restore kms panic output, but not through the bazillion of legacy
  code layers called fbdev/fbcon, there's just no way to make that
  work safely.

- With the module check change FBINFO_DEFAULT is always 0, so can be
  removed too.

That removes another change to cargo-cult stuff in kms drivers, yay!

Robert Foss c2c446ad29 drm: Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ to UAPI
Add DRM_MODE_ROTATE_ and DRM_MODE_REFLECT_ defines to the UAPI
as a convenience.

Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
through the atomic API, but realizing that userspace is likely to take
shortcuts and assume that the enum values are what is sent over the
wire.

As a result these defines are provided purely as a convenience to
userspace applications.

Changes since v3:
 - Switched away from past tense in comments
 - Add define name change to previously mis-spelled DRM_REFLECT_X comment
 - Improved the comment for the DRM_MODE_REFLECT_<axis> comment

Changes since v2:
 - Changed define prefix from DRM_MODE_PROP_ to DRM_MODE_
 - Fix compilation errors
 - Changed comment formatting
 - Deduplicated comment lines
 - Clarified DRM_MODE_PROP_REFLECT_ comment

Changes since v1:
 - Moved defines from drm.h to drm_mode.h
 - Changed define prefix from DRM_ to DRM_MODE_PROP_
 - Updated uses of the defines to the new prefix
 - Removed include from drm_rect.c
 - Stopped using the BIT() macro

Logan Gunthorpe f9b67f0014 dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro
Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.

I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.

Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.

To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)

Daniel Vetter f42e181935 drm/gem: Add DEFINE_DRM_GEM_FOPS
Sadly there's only 1 driver which can use it, everyone else is special
for some reason:

- gma500 has a horrible runtime PM ioctl wrapper that probably doesn't
  really work but meh.
- i915 needs special compat_ioctl handler because regrets.
- arcgpu needs to fixup the pgprot because (no idea why it can't do
  that in the fault handler like everyone else).
- tegra does even worse stuff with pgprot
- udl does something with vm_flags too ...
- cma helpers, etnaviv, mtk, msm, rockchip, omap all implement some
  variation on prefaulting.
- exynos is exynos, I got lost in the midlayers.
- vc4 has to reinvent half of cma helpers because those are too much
  midlayer, plus vm_flags dances.
- vgem also seems unhappy with the default vm_flags.

So pretty sad divergence and I'm sure we could do better, but not
really an idea. Oh well, maybe this macro here helps to encourage more
consistency at least going forward.

so no need for adding fake drm_info_node entries.
And finally there's no need to clean up on error,
drm_debugfs_cleanup() is called in the error path.

Laurent Pinchart 76adb460fd drm: Remove the struct drm_device platformdev field
The field contains a pointer to the parent platform device of the DRM
device. As struct drm_device also contains a dev pointer to the struct
device embedded in the platform_device structure, the platformdev field
is redundant. Remove it and use the dev pointer directly.

Shawn Guo 5922a7d075 drm: armada: use vblank hooks in struct drm_crtc_funcs
The vblank hooks in struct drm_driver are deprecated and only meant for
legacy drivers.  For modern drivers with DRIVER_MODESET flag, the hooks
in struct drm_crtc_funcs should be used instead.  As the result,
functions armada_drm_crtc_enable[disable]_irq() can be static, although
they are moved around a bit to save forward declaration.

The armada_crtc pointer array in struct armada_private is still kept in
there, because armada_debugfs.c still have reference to it.

Core code already makes drm_driver.get_vblank_counter hook optional by
letting drm_vblank_no_hw_counter be the default implementation for the

Chris Wilson 4e64e5539d drm: Improve drm_mm search (and fix topdown allocation) with rbtrees
The drm_mm range manager claimed to support top-down insertion, but it
was neither searching for the top-most hole that could fit the
allocation request nor fitting the request to the hole correctly.

In order to search the range efficiently, we create a secondary index
for the holes using either their size or their address. This index
allows us to find the smallest hole or the hole at the bottom or top of
the range efficiently, whilst keeping the hole stack to rapidly service
evictions.

v2: Search for holes both high and low. Rename flags to mode.
v3: Discover rb_entry_safe() and use it!
v4: Kerneldoc for enum drm_mm_insert_mode.

Gabriel Krisman Bertazi e4563f6ba7 drm: Rely on mode_config data for fb_helper initialization
Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure.  I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.

I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates.  The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

Dave Airlie 3806a271bf Merge tag 'drm-misc-next-2016-12-30' of git://anongit.freedesktop.org/git/drm-misc into drm-next
First -misc pull for 4.11:
- drm_mm rework + lots of selftests (Chris Wilson)
- new connector_list locking+iterators
- plenty of kerneldoc updates
- format handling rework from Ville
- atomic helper changes from Maarten for better plane corner-case handling
  in drivers, plus the i915 legacy cursor patch that needs this
- bridge cleanup from Laurent
- plus plenty of small stuff all over
- also contains a merge of the 4.10 docs tree so that we could apply the
  dma-buf kerneldoc patches

It's a lot more than usual, but due to the merge window blackout it also
covers about 4 weeks, so all in line again on a per-week basis. The more
annoying part with no pull request for 4 weeks is managing cross-tree
work. The -intel pull request I'll follow up with does conflict quite a
bit with -misc here. Longer-term (if drm-misc keeps growing) a
drm-next-queued to accept pull request for the next merge window during
this time might be useful.

I'd also like to backmerge -rc2+this into drm-intel next week, we have
quite a pile of patches waiting for the stuff in here.

Ville Syrjälä dbd4d5761e drm: Replace 'format->format' comparisons to just 'format' comparisons
Rather than compare the format u32s of two format infos, we can direclty
compare the format info pointers themselves. Noramlly all the ->format
pointers all point to somwehere in the big array, so this is a valid
way to test for equality.

Also drivers may want to point ->format at a private format info struct
instead (eg. for special compressed formats with extra planes), so
just comparing the pixel format values wouldn't necessaritly even work.
But comparing the pointers will also take care of that case.

Ville Syrjälä 272725c7db drm: Nuke fb->bits_per_pixel
Replace uses of fb->bits_per_pixel with fb->format->cpp[0]*8.
Less duplicated information is a good thing.

Note that I didn't put parens around the cpp*8 in the below cocci script,
on account of not wanting spurious parens all over the place. Instead I
did the unsafe way, and tried to look over the entire diff to spot if
any dangerous expressions were produced. I didn't see any.

There are some cases where previously the code did X*bpp/8, so the
division happened after the multiplication. Those are now just X*cpp
so the division effectively happens before the multiplication,
but that is perfectly fine since bpp is always a multiple of 8.

Jan Kara 1a29d85eb0 mm: use vmf->address instead of of vmf->virtual_address
Every single user of vmf->virtual_address typed that entry to unsigned
long before doing anything with it so the type of virtual_address does
not really provide us any additional safety.  Just use masked
vmf->address which already has the appropriate type.

Baoyou Xie 42b454590f drm/armada: mark symbols static where possible
We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/armada/armada_gem.c:215:27: warning: no previous prototype for 'armada_gem_alloc_object' [-Wmissing-prototypes]
drivers/gpu/drm/armada/armada_gem.c:423:1: warning: no previous prototype for 'armada_gem_prime_map_dma_buf' [-Wmissing-prototypes]

In fact, both functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
So this patch marks these functions with 'static'.

Now that the drm_connector_register() is gone from tda998x, we can
remove the mid-layer from armada-drm, eliminating the load, unload,
debugfs_init, and debugfs_cleanup callbacks from armada's drm_driver
structure.  No functional changes.
