Merge tag 'drm-next-2025-03-28' of https://gitlab.freedesktop.org/drm/kernel
Pull drm updates from Dave Airlie:
"Outside of drm there are some rust patches from Danilo who maintains
that area in here, and some pieces for drm header check tests.
The major things in here are a new driver supporting the touchbar
displays on M1/M2, the nova-core stub driver which is just the vehicle
for adding rust abstractions and start developing a real driver inside
of.
xe adds support for SVM with a non-driver specific SVM core
abstraction that will hopefully be useful for other drivers, along
with support for shrinking for TTM devices. I'm sure xe and AMD
support new devices, but the pipeline depth on these things is hard to
know what they end up being in the marketplace!

Video players (eg. mpv) do periodic XResetScreenSaver() calls to
keep the screen on while the video playing. The modesetting ddx
plumbs these straight through into the kernel as DPMS setproperty
ioctls, without any filtering whatsoever. When implemented via
atomic these end up as empty commits on the crtc (which will
nonetheless take one full frame), which leads to a dropped
frame every time XResetScreenSaver() is called.
Let's just filter out redundant DPMS property changes in the
kernel to avoid this issue.

Currently, DRM atomic uAPI allows only primary planes to be flipped
asynchronously. However, each driver might be able to perform async
flips in other different plane types. To enable drivers to set their own
restrictions on which type of plane they can or cannot flip, use the
existing atomic_async_check() from struct drm_plane_helper_funcs to
enhance this flexibility, thus allowing different plane types to be able
to do async flips as well.
Create a new parameter for the atomic_async_check(), `bool flip`. This
parameter is used to distinguish when this function is being called from
a plane update from a full page flip.
In order to prevent regressions and such, we keep the current policy: we
skip the driver check for the primary plane, because it is always
allowed to do async flips on it.

FB_DAMAGE_CLIPS is a plane property for damage handling. Its UAPI
should only use UAPI types. Hence replace struct drm_rect with
struct drm_mode_rect in drm_atomic_plane_set_property(). Both types
are identical in practice, so there's no change in behavior.

User-space is allowed to submit any property in an async flip as
long as the value doesn't change. However we missed one case:
as things stand, the kernel rejects no-op FB_ID changes on
non-primary planes. Fix this by changing the conditional and
skipping drm_atomic_check_prop_changes() only for FB_ID on the
primary plane (instead of skipping for FB_ID on any plane).

The i915 driver has a property to force the RGB range of an HDMI output.
The vc4 driver then implemented the same property with the same
semantics. KWin has support for it, and a PR for mutter is also there to
support it.
Both drivers implementing the same property with the same semantics,
plus the userspace having support for it, is proof enough that it's
pretty much a de-facto standard now and we can provide helpers for it.
Let's plumb it into the newly created HDMI connector.

Atomic modesetting code lacked support for specifying mouse cursor

the hotspot but the functionality was not implemented in the new atomic

Due to the lack of hotspots in the atomic paths userspace compositors
completely disable atomic modesetting for drivers that require it (i.e.
all paravirtualized drivers).
This change adds hotspot properties to the atomic codepaths throughtout
the DRM core and will allow enabling atomic modesetting for virtualized

The TV mode property has been around for a while now to select and get the
current TV mode output on an analog TV connector.
Despite that property name being generic, its content isn't and has been
driver-specific which makes it hard to build any generic behaviour on top
of it, both in kernel and user-space.
Let's create a new enum tv norm property, that can contain any of the
analog TV standards currently supported by kernel drivers. Each driver can
then pass in a bitmask of the modes it supports, and the property
creation function will filter out the modes not supported.
We'll then be able to phase out the older tv mode property.

drm_gem_plane_helper_prepare_fb() was using
drm_atomic_set_fence_for_plane() which ignores all implicit fences when an
explicit fence is already set. That's rather unfortunate when the fb still
has a kernel fence we need to wait for to avoid presenting garbage on the
screen.
So instead update the fence in the plane state directly. While at it also
take care of all potential GEM objects and not just the first one.
Also remove the now unused drm_atomic_set_fence_for_plane() function, new
drivers should probably use the atomic helpers directly.

The DRM_UT_STATE controls whether we're calling

that call is made in the drm_mode_atomic_ioctl(), whereas we have
multiple users of the drm_atomic_commit() function in the kernel
(framebuffer emulation, drm_atomic_helper_dirtyfb, etc.).
This leads to multiple states being committed but never actually
displayed even though we asked to have verbose atomic state debugging.
Let's move the call to drm_atomic_print_new_state() to
drm_atomic_commit() to make sure we don't miss any. Non-blocking commits
were never logged though, and it would create too much churn in the logs

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.
