The current code does not look correct, and the reason for it is
probably lost. Since this now generates a compiler warning,
fix it to what makes sense.

Parts of commit <8fbf9d92a7bc> (“drm/vmwgfx: Implement the
cursor_set2 callback v2”) were not moved over when we started
atomic mode set development because at that time the DRM did
not support cursor hotspots in the fb struct.
This patch fixes what was not moved over.

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.

Again stopping the vblank before uninstalling the irq handler is kinda
the wrong way round, but the fb_off stuff should take care of

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.

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.

- 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_

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro

I'm personally trying to include highmem.h inside scatterlist.h and this

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

I've broken this by removing the backoff handling from the
set_config2atomic helper in
commit 38b6441e4e75c0b319cfe4d9364c1059fc1e3c2b
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date: Wed Mar 22 22:50:58 2017 +0100
drm/atomic-helper: Remove the backoff hack from set_config
Fixing this properly would mean we get to wire the acquire_ctx all the
way through vmwgfx fbdev code, and doing the same was tricky for the
shared fbdev layer. Probably much better to look into refactoring the
entire code to use the helpers, but since that's not a viable
long-term solution fix the issue by open-coding a vmwgfx version of
set_config, that does the legacy backoff dance internally.
Note: Just compile-tested. The idea is to take
drm_mode_set_config_internal(), remove the "is this a legacy driver"
check, and whack the drm_atomic_legacy_backoff trickery at the end.
Since drm_atomic_legacy_backoff is for atomic commits only we need to
open-code it.

Atomic helpers really want this instead of the hacked-up legacy
backoff trick, which unfortunately prevents drivers from using their
own private drm_modeset_locks.
Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which
don't yet use the new atomic color mgmt/gamma table stuff. Would be
nice if they could switch over and just hook up
drm_atomic_helper_legacy_gamma_set() instead.

The scanout surface size is the smaller of max texture size and
max STDU 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.

This reverts commit 2d8e60e8b074 ("drm/vmwgfx: Replace numeric
parameter like 0444 with macro")
The commit belongs to the series of 1285 patches sent to LKML on
2016-08-02, it changes the representation of file permissions from the
octal value "0600" to "S_IRUSR | S_IWUSR".
The general consensus was that the changes does not increase
readability, quite the opposite; 0600 is easier to parse mentally than
S_IRUSR | S_IWUSR.
It also causes argument inconsistency, due to commit 04319d89fbec
("drm/vmwgfx: Add an option to change assumed FB bpp") that added
another call to module_param_named() where the permissions are written
as 0600.

vmw_ldu_crtc_helper_commit() is not called if
drm_atomic_crtc_needs_modeset() decides nothing related to CRTC timing has
changed.
So a better place for this code is in vmw_ldu_primary_plane_atomic_update()
since we will need to update ld->fb every time the FB is updated.

Pinning fbdev's FB at the start of VRAM prevents X from pinning
its FB. Since for ldu, the fb would be pinned anyway during a
mode set, just skip pinning it in fbdev.
This is not the best solution, but since ldu is not used much
anymore, it seems like a reasonable workaround.

We can no longer make the assumption that vmw_stdu_update_st() will
be called when there's a valid display surface attached. So
instead of using display_srf for width and height, make a record of
these paremeters when the screen target is first defined.
