5f6c871fe9 drm/qxl: properly free qxl releases
Reorganize qxl_device_fini() a bit.
Add missing unpin() calls.

Count releases.  Add wait queue for releases.  That way
qxl_device_fini() can easily wait until everything is
ready for proper shutdown.

49a3f51dfe drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backends
This patch replaces the vmap/vunmap's use of raw pointers in GEM object
functions with instances of struct dma_buf_map. GEM backends are
converted as well. For most of them, this simply changes the returned type.

TTM-based drivers now return information about the location of the memory,
either system or I/O memory. GEM VRAM helpers and qxl now use ttm_bo_vmap()
et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of
implementing their own vmap callbacks.

v7:
	* init QXL cursor to mapped BO buffer (kernel test robot)
v5:
	* update vkms after switch to shmem
v4:
	* use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al. (Daniel, Christian)
	* fix a trailing { in drm_gem_vmap()
	* remove several empty functions instead of converting them (Daniel)
	* comment uses of raw pointers with a TODO (Daniel)
	* TODO list: convert more helpers to use struct dma_buf_map

7ce84471e3 drm: convert .debugfs_init() hook to return void.
As a result of commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail) and changes to various debugfs
functions in drm/core and across various drivers, there is no need for
the drm_driver.debugfs_init() hook to have a return value. Therefore,
declare it as void.

This also includes refactoring all users of the .debugfs_init() hook to
return void across the subsystem.

v2: include changes to the hook and drivers that use it in one patch to
prevent driver breakage and enable individual successful compilation of
this change.

51ea742c87 drm/qxl: stop using TTM to call driver internal functions
The ttm_mem_io_* functions were intended to be internal to TTM and
shouldn't have been used in a driver. They were exported in commit
afe6804c045fbd69a1b75c681107b5d6df9190de just for QXL.

Instead call the qxl_ttm_io_mem_reserve() function directly and
completely drop the free call since that is a dummy on QXL.

90adda2ce8 drm/qxl: cover all crtcs in shadow bo.
The qxl device supports only a single active framebuffer ("primary
surface" in spice terminology).  In multihead configurations are handled
by defining rectangles within the primary surface for each head/crtc.

Userspace which uses the qxl ioctl interface (xorg qxl driver) is aware
of this limitation and will setup framebuffers and crtcs accordingly.

Userspace which uses dumb framebuffers (xorg modesetting driver,
wayland) is not aware of this limitation and tries to use two
framebuffers (one for each crtc) instead.

The qxl kms driver already has the dumb bo separated from the primary
surface, by using a (shared) shadow bo as primary surface.  This is
needed to support pageflips without having to re-create the primary
surface.  The qxl driver will blit from the dumb bo to the shadow bo
instead.

So we can extend the shadow logic:  Maintain a global shadow bo (aka
primary surface), make it big enough that dumb bo's for all crtcs fit in
side-by-side.  Adjust the pageflip blits to place the heads next to each
other in the shadow.

With this patch in place multihead qxl works with wayland.

bf8744e40c qxl: refactor to use drm_fb_helper_fbdev_setup
Lots of code can be removed by relying on fb-helper:
- "struct drm_framebuffer" moves to fb_helper.fb.
- "struct drm_gem_object" moves to fb_helper.obj[0].
- "struct qxl_device" can be inferred as drm_fb_helper is embedded.
- qxl_user_framebuffer_create -> drm_gem_fb_create.
- qxl_user_framebuffer_destroy -> drm_gem_fb_destroy.
- qxl_fbdev_destroy -> drm_fb_helper_fbdev_teardown + vfree(shadow).

Remove unused code:
- qxl_fbdev_qobj_is_fb, qxl_fbdev_set_suspend.
- Unused fields of qxl_fbdev: delayed_ops, delayed_ops_lock, size.

Misc notes:
- The dirty callback is preserved as it is necessary to trigger update
  commands in the hw (the screen stays black otherwise).
- No idea when .create_handle in drm_framebuffer_funcs is used, but use
  the same drm_gem_fb_create_handle to match drm_gem_fb_funcs.
- I don't know why qxl_fb_find_or_create_single used to check for an
  existing framebuffer and removed that check to match other drivers.
- Use of drm_fb_helper_fbdev_teardown also requires "info->fbdefio" to
  be dynamically allocated. Replace the existing defio config by
  drm_fb_helper_defio_init to accomodate this.

Testing results: startx with fbdev, modesetting and qxl all seems to
work. Tested also with CONFIG_DRM_FBDEV_EMULATION=n, fbdev obviously
fails but others are fine. QEMU -spice and QEMU -spice with vdagent and
multiple (resized) displays (via remote-viewer) also works.
unbind vtconsole and rmmod has *not* regressed (i.e. it still trips on a
use-after-free in qxl_check_idle via qxl_ttm_fini).

Ideally setup/teardown is replaced by drm_fbdev_generic_setup as that
would result in further code reduction, improve error handling (like not
leaking shadow memory), but unfortunately QXL has no implementation for
qxl_gem_prime_vmap.

7a31805ba2 qxl: keep separate release_bo pointer
qxl expects that list_first_entry(release->bos) returns the first
element qxl added to the list.  ttm_eu_reserve_buffers() may reorder
the list though.

Add a release_bo field to struct qxl_release and use that instead.

9428088c90 drm/qxl: reapply cursor after resetting primary
QXL associates mouse state with its primary plane.

Destroying a primary plane and putting a new one in place has the side
effect of destroying the cursor as well.

This commit changes the driver to reapply the cursor any time a new
primary is created. It achieves this by keeping a reference to the
cursor bo on the qxl_crtc struct.

This fix is very similar to

commit 4532b241a4b7 ("drm/qxl: reapply cursor after SetCrtc calls")

which got implicitly reverted as part of implementing the atomic
modeset feature.

62676d10b4 qxl: alloc & use shadow for dumb buffers
This patch changes the way the primary surface is used for dumb
framebuffers.  Instead of configuring the bo itself as primary surface
a shadow bo is created and used instead.  Framebuffers can share the
shadow bo in case they have the same format and resolution.

On atomic plane updates we don't have to update the primary surface in
case we pageflip from one framebuffer to another framebuffer which
shares the same shadow.  This in turn avoids the flicker caused by the
primary-destroy + primary-create cycle, which is very annonying when
running wayland on qxl.

The qxl driver never actually writes to the shadow bo.  It sends qxl
blit commands which update it though, and the spice server might
actually execute them (and thereby write to the shadow) in case the
local rendering is kicked for some reason.  This happens for example in
case qemu is asked to write out a dump of the guest display (screendump
monitor command).

ecefd94e8b qxl: drop mode_info.modes & related code.
very old qxl hardware revisions (predating qxl ksm support by a few
years) supported a fixed list of video modes only.  The list is still
provided by the virtual hardware, for backward compatibility reasons.

The qxl kms driver never ever looks at it, except for dumping it to
the kernel log at load time in case debug logging is enabled.  Drop
that pointless code.
