Backmerge tag 'v4.13-rc5' into drm-next

Linux 4.13-rc5

There's a really nasty nouveau collision, hopefully someone can take a look
once I pushed this out.

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)

Sinclair Yeh 7b009e7679 drm/vmwgfx: Limit max desktop dimensions to 8Kx8K
This was originally chosen to be an arbitrarily large number.  However,
some user mode may actually try to set a 16Kx16K mode and run into other
issues.

Since 8Kx8K is the current texture limit for Mesa LLVM driver, we will
just use this limit for now.

Laurent Pinchart 0b20a0f8c3 drm: Add old state pointer to CRTC .enable() helper function
The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.

While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.

Sinclair Yeh a1ac633912 drm/vmwgfx: Fix large topology crash
The previous attempt at this had an issue with with num_clips > 1
because it would always end up using the coordinates of the last
clip while using width and height calculated from the bounding
box of all the clips.

So if the last clip happens to be not at the top-left corner of
the bounding box, the CPU blit operation would go out of bounds.

The original intent was to coalesce all the clips into one blit,
and to do that we need to also track the starting point of the
content buffer.

Sinclair Yeh 810b3e1683 drm/vmwgfx: Support topology greater than texture size
Most of the display servers today use a single surface to represent the
entire desktop even if it's stretched across multiple screens.

For vmwgfx with STDU, the maximum surface size is limited to the
maximum texture size on the host.  On a 2D VM, this limits our
ability to support configurations with more than one 4K monitor.

To get past this limitation, we will now allow using a large DMA buf
as the framebuffer, and take care of blitting contents from this DMA buf
to the display buffer.

Switch over to using internal atomic API for mode set.

This removes the legacy set_config API, replacing it with
drm_atomic_helper_set_config().  The DRM helper will use various

v2:
* Avoid a clash between page-flip pinning and setcrtc pinning, modify
the page-flip code to use the page-flip helper and the atomic callbacks.
To enable this, we will need to add a wrapper around atomic_commit.

Atomic mode set requires us to refactor existing vmw_stdu_crtc_set_config
code into sections that check the validity of the new mode, and sections
that actually program the hardware state.

vmw_du_crtc_atomic_check() takes CRTC-related checking code.  In a later

checking code.

* The state->num_connector is actually the total number of potential
  connectors, not just the one associated with the display unit.
  The proper one to check is ->connector_mask.

* Add the check to only allow plane state to be the same as crtc state
  (Thanks to mlankhorst)

* Make sure to turn on SVGA mode before using VRAM.  SVGA mode is
  disabled in master_drop if dbdev is not running.

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.

Thomas Hellstrom beca4cf553 drm/vmwgfx: Fix corner case screen target management
When the surface backing a framebuffer doesn't match the framebuffer's
dimensions, the screen target code would test the framebuffer dimensions
rather than the surface dimensions when deciding whether to bind the
surface as a screen target directly. This causes a screen target -
surface dimension mismatch and a subsequent device error.

Fix this by testing against the surface dimension.

v2: Fix review comments by Sinclair Yeh.

Thomas Hellstrom 93cd16817a drm/vmwgfx: Kill some lockdep warnings
Some global KMS state that is elsewhere protected by the mode_config
mutex here needs to be protected with a local mutex. Remove corresponding
lockdep checks and introduce a new driver-private global_kms_state_mutex,
and make sure its locking order is *after* the crtc locks in order to
avoid having to release those when the new mutex is taken.

Thomas Hellstrom b1097aeb6f drm/vmwgfx: Rework screen target page flips v2
Gnome-Shell / Wayland assumes that page-flips can be done on a crtc
regardless of framebuffer size and the crtc position within the
framebuffer.

Therefore rework the screen target code to correctly handle changes in
framebuffer size and content_fb_type. Also make sure that we update
the screen target correctly when the content_fb_type is not
SAME_AS_DISPLAY.

This commit breaks out the framebuffer binding code from crtc_set so it
can be used both from page_flip() and crtc_set() and reworks those
functions a bit to be more robust.

v2: Address review comments by Sinclair Yeh.

Fixes native drm clients like Fedora 23 Wayland which now appears to
be able to use cursor hotspots without strange cursor offsets.
Also fixes a couple of ignored error paths.

Since the core drm cursor hotspot is incompatible with the legacy vmwgfx
hotspot (the core drm hotspot is reset when the drm_mode_cursor ioctl
is used), we need to keep track of both and add them when the device
hotspot is set. We assume that either is always zero.

Sinclair Yeh f89c6c321c drm/vmwgfx: Replace SurfaceDMA usage with SurfaceCopy in 2D VMs
This patch address the following underlying issues with SurfaceDMA

* SurfaceDMA command does not work in a 2D VM, but we can wrap a
  proxy surface around the same DMA buffer and use the SurfaceCopy
  command which does work in a 2D VM.

* Wrapping a DMA buffer with a proxy surface also gives us an
  added optimization path for the case when the DMA buf
  dimensions match the mode.  In this case, the DMA buf can
  be pinned as the display surface, saving an extra copy.
  This only works in a 2D VM because we won't be doing any
  rendering operations directly to the display surface.

v2
* Moved is_dmabuf_proxy field to vmw_framebuffer_surface
* Undone coding style changes
* Addressed other issues from review
