Pull drm updates from Dave Airlie:
"As part of building up nova-core/nova-drm pieces we've brought in some
rust abstractions through this tree, aux bus being the main one, with
devres changes also in the driver-core tree. Along with the drm core
abstractions and enough nova-core/nova-drm to use them. This is still
all stub work under construction, to build the nova driver upstream.

The other big NVIDIA related one is nouveau adds support for
Hopper/Blackwell GPUs, this required a new GSP firmware update to
570.144, and a bunch of rework in order to support multiple fw
interfaces.

There is also the introduction of an asahi uapi header file as a
precursor to getting the real driver in later, but to unblock
userspace mesa packages while the driver is trapped behind rust
enablement.

drm/{i915,xe}: convert i915 and xe display members into pointers

As the first step towards making struct intel_display an opaque pointer
in i915 and xe drivers, convert the struct drm_i915_private and struct
xe_device display members into pointers.

Initially, add temporary struct intel_display __display members, and
point display at it to avoid dynamic allocation. In the future, we can
drop this, and switch to dynamic allocation.

The conversion is done simply with sed:

sed -i 's/&\([a-zA-Z0-9_>.-]*\)\(dev_priv\|i915\|xe\)->display\([^.]\)/\1\2->display\3/g' \
$(git ls-files -- drivers/gpu/drm/i915 drivers/gpu/drm/xe)

sed -i 's/\(dev_priv\|i915\|xe\)->display\./\1->display->/g' \
$(git ls-files -- drivers/gpu/drm/i915 drivers/gpu/drm/xe)

With a couple of manual tweaks on top.

drm/i915/error: drop dmesg suggestion to file bugs on GPU hangs

drm/i915/error: drop dmesg suggestion to file bugs on GPU hangs

We haven't updated the DRIVER_TIMESTAMP since commit 3570bd989acc
("drm/i915: Update DRIVER_DATE to 20230929") 1½ years ago. Before then,
the previous update was commit 139caf7ca286 ("drm/i915: Update
DRIVER_DATE to 20201103") 4+ years ago. The DRIVER_DATE has also been
removed altogether.

We've used the DRIVER_TIMESTAMP to log suggestions to file bugs on GPU
hangs when they happen on a driver less than six months old. Combined
with the sporadic DRIVER_TIMESTAMP updates, we really haven't logged the
suggestions for years.

Just stop logging the suggestion to file bugs altogether, and remove
DRIVER_TIMESTAMP. This doesn't really change anything wrt to logging GPU
errors or how we handle bugs. And effectively we already stopped logging
the message a year ago when we stopped updating DRIVER_TIMESTAMP.

Instead, add an unconditional message about the GPU error state
location.

drm/i915: use graphics version instead of PCH split in error capture

Avoid using PCH checks in core i915 code, in preparation for moving PCH
handling to display.

drm/i915: use display snapshot mechanism for display irq regs

Move more display specific parts of GPU error logging behind the display
snapshot interface.

With the display register capture reduced to just one register, DERRMR,
there's quite a bit of boilerplate here. However, it's still a nice
abstraction and removes a DISPLAY_VER() usage from core i915. With this
approach, it's also easy to add to xe as needed.
