This reverts commit 8283ac7871a959848e09fc6593b8c12b8febfee6.
Although the Solid Fill planes patchset got all reviews and
acknowledgements, it doesn't fulfill requirements for the new uABI. It
has neither corresponding open-source userspace implementation nor the
IGT tests coverage. Reverting this patchset until userspace obligations
are fulfilled.

Given that prop changes may lead to modesetting, which would defeat the
fast path of the async flip, refuse any atomic prop change for async
flips in atomic API. The only exception is the framebuffer ID to flip
to. Currently the only plane type supported is the primary one.

This new IOCTL allows callers to close a framebuffer without
disabling planes or CRTCs. This takes inspiration from Rob Clark's
unref_fb IOCTL [1] and DRM_MODE_FB_PERSIST [2].
User-space patch for wlroots available at [3]. IGT test available
at [4].
v2: add an extra pad field just in case we want to extend this IOCTL
in the future (Pekka, Sima).

Instead of the per minor directories only create a single debugfs
directory for the whole device directly when the device is initialized.
For DRM devices each minor gets a symlink to the per device directory
for now until we can be sure that this isn't useful any more in any way.
Accel devices create only the per device directory and also drops the mid
layer callback to create driver specific files.
v2: cleanup accel component as well
v3: fix typo when debugfs is disabled

Add functions drm_edid_override_set() and drm_edid_override_reset() to
support "edid_override" connector debugfs, and to hide the details about
it in drm_edid.c. No functional changes at this time.
Also note in the connector.override_edid flag kernel-doc that this is
only supposed to be modified by the code doing debugfs EDID override
handling. Currently, it is still being modified by amdgpu in
create_eml_sink() and handle_edid_mgmt() for reasons unknown. This was
added in commit 4562236b3bc0 ("drm/amd/dc: Add dc display driver (v2)")
and later moved to amdgpu_dm.c in commit e7b07ceef2a6 ("drm/amd/display:

Required bump from v5.13-rc3 to v5.14-rc3, and to pick up sysfb compilation fixes.
Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

There's two stages of manual upload/invalidate displays:
- just handling dirtyfb and uploading the entire fb all the time
- looking at damage clips
In the latter case we support it through fbdev emulation (with
fb_defio), atomic property, and with the dirtfy clip rects.
Make sure at least the atomic property is set up as the main official
interface for this. Ideally we'd also check that
drm_atomic_helper_dirtyfb() is used and that fbdev defio is set up,
but that's quite a bit harder to do. Ideas very much welcome.
From a cursor audit drivers seem to be getting this right mostly, but
better to make sure. At least no one is bypassing the accessor
function.
v2:
- use drm_warn_once with a meaningful warning string (José)
- don't splat in the atomic check code for everyone (intel-gfx-ci)

Introduce per-plane and per-CRTC scaling filter properties to allow
userspace to select the driver's default scaling filter or
Nearest-neighbor(NN) filter for upscaling operations on CRTC and
plane.
Drivers can set up this property for a plane by calling
drm_plane_create_scaling_filter() and for a CRTC by calling
drm_crtc_create_scaling_filter().
NN filter works by filling in the missing color values in the upscaled
image with that of the coordinate-mapped nearest source pixel value.
NN filter for integer multiple scaling can be particularly useful for
for pixel art games that rely on sharp, blocky images to deliver their
distinctive look.

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.

The docs say possible_clones should always include the encoder itself.
Since most drivers don't want to deal with the complexities of cloning
let's allow them to set possible_clones=0 and instead we'll fix that
up in the core.
We can't put this special case into drm_encoder_init() because drivers
will have to fill up possible_clones after adding all the relevant
encoders. Otherwise they wouldn't know the proper encoder indexes to
use. So we'll just do it just before registering the device.
v2: Don't set the bit if possible_clones!=0 so that the
validation (coming soon) will WARN (Thomas)
Fix up the docs to allow possible_clones==0 (Daniel)
.late_register() is too late, introduce drm_mode_config_validate()
which gets called _before_ we register the char device (Daniel)

Currently the DispID tile block gets parsed in drm_get_edid(), which
is an odd place for it considering we parse nothing else there. Also
this doesn't work for override EDIDs since
drm_connector_update_edid_property() refuses to do its job twice
in such cases. Thus we never update the tile property with results
of the DispID tile block parsing during drm_get_edid().
To fix this let's just move the tile block parsing to happen during
drm_connector_update_edid_property(), which is where we parse a bunch
of other stuff as well (and where we update both the EDID and tile
properties).

Drivers must set the quirk_addfb_prefer_host_byte_order quirk to make
the drm_mode_addfb() compat code work correctly on bigendian machines.
If they don't they interpret pixel_format values incorrectly for bug
compatibility, which in turn implies the ADDFB2 ioctl does not work
correctly then. So block it to make userspace fallback to ADDFB.

deadlock.

The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.
But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.
And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.
This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.
v2: Fixup docs even better!
v3: Make it actually work ...
v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

I got confused every time I audited what that lock_all is doing in
there until realizing it's for legacy kms only. Make that a notch more
obvious by having 2 entirely different paths.
While at it also move the atomic version of this into
drm_framebuffer.c, there's no reason it needs to be in drm_atomic.c.
That way it becomes a simple static function.

Subsequent patches will introduce reference counting APIs that are more
consistent with similar APIs throughout the Linux kernel. These APIs use
the _get() and _put() suffixes and will collide with this existing
function.
Rename the function to drm_mode_object_add() which is a slightly more
accurate description of what it does. Also the kerneldoc for this
function gives an indication that it's badly named because it doesn't
actually acquire a reference to anything.

Instead of trying to do everything in 1 go, just do a basic safe
conversion first. We've been bitten by too many regressions in the
past.
This patch only converts drm_framebuffer_remove to atomic. The
regression sensitive part is split out to a separate patch.
v2:
- Remove plane->fb assignment, done by drm_atomic_clean_old_fb.
- Add WARN_ON when atomic_remove_fb fails.
- Always call drm_atomic_state_put.
v3:
- Use drm_drv_uses_atomic_modeset
- Handle the case where the first plane-disable-only commit fails
with -EINVAL. Some drivers do not support this, fall back to
disabling all crtc's in this case.
v4:
- Solve vmwgfx compatibility issue in their driver, was fixed in this
patch by v3.
- Move only disabling primary to a separate patch.

This is just a cleanup, no functional change.
The fixup code for 1366x768 in drm_mode_create_from_cmdline_mode() is
basically a copy of the existing code in drm_edid.c. Make the latter
code public so that it can be called from the former function.

Create one timeline context for each CRTC to be able to handle out-fences
and signal them. It adds a few members to struct drm_crtc: fence_context,
where we store the context we get from fence_context_alloc(), the
fence seqno and the fence lock, that we pass in fence_init() to be
used by the fence.

Imo zpos, rotatation, blending eq (once we have it) and all that
should be in drm_blend.c, since those are all about how exactly the

move it to the right place too.
