Initially vmware buffer objects were only used as DMA buffers, so the name
DMA buffer was a natural one. However, currently they are used also as
dumb buffers and MOBs backing guest backed objects so renaming them to
buffer objects is logical. Particularly since there is a dmabuf subsystem
in the kernel where a dma buffer means something completely different.
This also renames user-space api structures and IOCTL names
correspondingly, but the old names remain defined for now and the ABI
hasn't changed.
There are a couple of minor style changes to make checkpatch happy.

vmw_du_crtc_atomic_check() prevents us from enabling a crtc

Due to that same reason, I'm actually not sure what the checks here are

This blit was previously performed using two large vmaps, one of which

When validating legacy surfaces, the backup bo might be destroyed at
surface validate time. However, the kms resource validation code may have
the bo reserved, so we will destroy a locked mutex. While there shouldn't
be any other users of that mutex when it is destroyed, it causes a lock
leak and thus throws a lockdep error.
Fix this by having the kms resource validation code hold a reference to
the bo while we have it reserved. We do this by introducing a validation
context which might come in handy when the kms code is extended to validate
multiple resources or buffers.

Buffer objects need to be either pinned or reserved while a map is active,
that's not the case here, so avoid caching the framebuffer map.
This will cause increasing mapping activity mainly when we don't do
page flipping.
This fixes occasional garbage filled screens when the framebuffer has been
evicted after the map.
Since in-kernel mapping of whole buffer objects is error-prone on 32-bit
architectures and also quite inefficient, we will revisit this later.

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

Most of the display servers today use a single surface to represent the

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.

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
patch, vmw_du_primary_plane_atomic_check() will take framebuffer-related
checking code.
These helpers won't be called until we flip on the atomic support
flag or set drm_crtc_funcs->set_config to using the atomic
helper.
v2:
* 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.
v3:
* Moved dot clock override to crtc_atomic_check

Add connector handling functions. Start tracking is_implicity in
the connector state. Eventually, this field should be tracked
exclusively in a connector state.
Now that plane and connector states have been created, we can also
activate the code that use CRTC state.

Add plane state handling functions.
We have to keep track of a few plane states so we cannot use the
DRM helper for this.
Created vmw_plane_state along with functions to reset, duplicate,
and destroty it.

* Removed cursor clean up special case
