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/amdgpu: fix use-after-unlock in eviction fence destroy

The eviction fence destroy path incorrectly calls dma_fence_put() on
evf_mgr->ev_fence after releasing the ev_fence_lock. This introduces a
potential use-after-unlock or race because another thread concurrently
modifies evf_mgr->ev_fence.

Fix this by grabbing a local reference to evf_mgr->ev_fence under the
lock and using that for dma_fence_put() after waiting.

drm/amdgpu: Fix display freezing issue when resizing apps

The display is freezing because the amdgpu_userq_wait_ioctl()
is waiting for a non-user queue fence(specifically, the PT update fence).

RootCause:
The resume_work is initiated by both amdgpu_userq_suspend and
amdgpu_userqueue_ensure_ev_fence at same time. The amdgpu_userq_suspend
signals a dma-fence and subsequently triggers the resume_work, which is
intended to replace the existing fence by creating new dma-fence. However,
following this, the amdgpu_userqueue_ensure_ev_fence schedules another
resume_work that generates a new dma-fence, thereby replacing the one
created by amdgpu_userq_suspend. Consequently, the original fence will
never be signaled.

drm/amdgpu: simplify eviction fence suspend/resume

The basic idea in this redesign is to add an eviction fence only in UQ
resume path. When userqueue is not present, keep ev_fence as NULL

Main changes are:
- do not create the eviction fence during evf_mgr_init, keeping
evf_mgr->ev_fence=NULL until UQ get active.
- do not replace the ev_fence in evf_resume path, but replace it only in
uq_resume path, so remove all the unnecessary code from ev_fence_resume.
- add a new helper function (amdgpu_userqueue_ensure_ev_fence) which
will do the following:
- flush any pending uq_resume work, so that it could create an
eviction_fence
- if there is no pending uq_resume_work, add a uq_resume work and
wait for it to execute so that we always have a valid ev_fence
- call this helper function from two places, to ensure we have a valid
ev_fence:
- when a new uq is created
- when a new uq completion fence is created

v2: Worked on review comments by Christian.
v3: Addressed few more review comments by Christian.
v4: Move mutex lock outside of the amdgpu_userqueue_suspend()
function (Christian).

drm/amdgpu: suspend gfx userqueues

This patch adds suspend support for gfx userqueues. It typically does
the following:
- adds an enable_signaling function for the eviction fence, so that it
can trigger the userqueue suspend,
- adds a delayed work to handle suspending of the eviction_fence
- adds a suspend function to handle suspending of userqueues which
suspends all the queues under this userq manager and signals the
eviction fence,
- adds a function to replace the old eviction fence with a new one and
attach it to each of the objects,
- adds reference of userq manager in the eviction fence container so
that it can be used in the suspend function.

V2: Addressed Christian's review comments:
- schedule suspend work immediately

V4: Addressed Christian's review comments:
- wait for pending uq fences before starting suspend, added
queue->last_fence for the same
- accommodate ev_fence_mgr into existing code
- some bug fixes and NULL checks

V5: Addressed Christian's review comments (gitlab)
- Wait for eviction fence to get signaled in destroy,
don't signal it
- Wait for eviction fence to get signaled in replace fence,
don't signal it

V6: Addressed Christian's review comments
- Do not destroy the old eviction fence until we have it replaced
- Change the sequence of fence replacement sub-tasks
- reusing the ev_fence delayed work for userqueue suspend as well
(Shashank).

V7: Addressed Christian's review comments
- give evf_mgr as argument (instead of fpriv) to replace_fence()
- save ptr to evf_mgr in ev_fence (instead of uq_mgr)
- modify suspend_all_queues logic to reflect error properly
- remove the garbage drm_exec_lock section in wait_for_signal
- grab the userqueue mutex before starting the wait for fence
- remove the unrelated gobj check from signal_ioctl

- This fence is attached to all the gem buffers created
by this process.
- This fence is detached to all the gem buffers at postclose_kms.

This framework will be further used for usermode queues.

V2: Addressed review comments from Christian
- keep fence_ctx and fence_seq directly in fpriv
- evcition_fence should be dynamically allocated
- do not save eviction fence instance in BO, there could be many
such fences attached to one BO
- use dma_resv_replace_fence() in detach

V3: Addressed review comments from Christian
- eviction fence create and destroy functions should be called
only once from fpriv create/destroy
- use dma_fence_put() in eviction_fence_destroy

V4: Addressed review comments from Christian:
- create a separate ev_fence_mgr structure
- cleanup fence init part
- do not add a domain for fence owner KGD

V5: Addressed review comments from Christian:
- drop the dma_fence_is_signaled check
- use a local variable to access evf_mgr->ev_fence under the
spin_lock() multiple places
- remove the vm->is_compute_ctx check to attach gfx eviction fence,
in gem_object_open

V6: Addressed review comments from Christian:
- drop the return value from eviction_fence_signal
- reserve_fence should be the first thing inside the
attach_eviction_fence function, also keep the resv_add_fence inside
the lock
- remove the unwanted ev_fence check inside detach function
- fix wrong variable check in eviction_fence_init function
- return the error value of eviction_fence_init to the caller, dont
keep it void.
- fail gem_object_open if attaching of eviction_fence fails
- detach the eviction fence only when amdgpu_vm_is_bo_always_valid
is not true.

V7: Addressed review comments from Christian:
- Do not add a uq_mgr ptr in ev_fence, rather add evf_mgr

V8: Move eviction fence enabling into separate patch for CI
