drm/amdgpu: Enhance Cleaner Shader Handling in GFX v9.0 Architecture v2

This commit modifies the gfx_v9_0_ring_emit_cleaner_shader function
to use a switch statement for cleaner shader emission based on the
specific GFX IP version.

The function now distinguishes between different IP versions, using
PACKET3_RUN_CLEANER_SHADER_9_0 for the versions 9.0.1, 9.1.0,
9.2.1, 9.2.2, 9.3.0, and 9.4.0, while retaining

drm/amdgpu: Add PACKET3_RUN_CLEANER_SHADER_9_0 for Cleaner Shader execution

This commit introduces the PACKET3_RUN_CLEANER_SHADER_9_0 definition,
which is a command packet utilized to instruct the GPU to execute the
cleaner shader for the GFX9.0 graphics architecture.

The cleaner shader is a piece of GPU code that is responsible for
clearing or initializing essential GPU resources, such as Local Data
Share (LDS), Vector General Purpose Registers (VGPRs), and Scalar
General Purpose Registers (SGPRs). Properly clearing these resources  is
vital for ensuring data isolation and security between different
workloads executed on the GPU.

When the GPU receives this packet, it fetches and runs the cleaner
shader instructions from the specified location in the packet.  Thus by
preventing data leaks and ensuring that previous job states do not
interfere with subsequent workloads.

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: fix the memleak caused by fence not released

Encountering a taint issue during the unloading of gpu_sched
due to the fence not being released/put. In this context,
amdgpu_vm_clear_freed is responsible for creating a job to
update the page table (PT). It allocates kmem_cache for
drm_sched_fence and returns the finished fence associated
with job->base.s_fence. In case of Usermode queue this finished
fence is added to the timeline sync object through
amdgpu_gem_update_bo_mapping, which is utilized by user
space to ensure the completion of the PT update.

drm/amdgpu: Fix display freeze lockup error

A deadlock situation has arised between the userq
signal ioctl and the eviction fence. In this scenario,
the function amdgpu_userq_signal_ioctl() has acquired a reservation
lock on the read/write buffer object (BO) through drm_exec.
Subsequently, it calls amdgpu_userqueue_ensure_ev_fence(),
which is in a waiting for the userq resume work.
Meanwhile, the userq suspend worker has initiated the userq resume
work(amdgpu_userqueue_resume_worker). This userq resume work attempts
to validate the vm->done BO, leading to amdgpu_userqueue_validate_bos
also attempting to reservation lock the same write BO that is already
locked by amdgpu_userq_signal_ioctl.
As a result, the resume work becomes stalled, causing
amdgpu_userqueue_ensure_ev_fence to remain in a waiting state.

drm/amdgpu: Fix Illegal opcode in command stream Error

When applications closes, it triggers the drm_file_free
function which subsequently releases all allocated buffer
objects. Concurrently, the resume_worker thread will attempt
to map the usermode queue. However, since the wptr buffer

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

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

drm/amdgpu: add gfx eviction fence helpers

This patch adds basic eviction fence framework for the gfx buffers.
The idea is to:
- One eviction fence is created per gfx process, at kms_open.
- 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

drm/amdgpu: bypass SRIOV check for shadow size info

Currently, the shadow FW space size and alignment information is
protected under a flag (adev->gfx.cp_gfx_shadow) which gets set
only in case of SRIOV setups.
if (amdgpu_sriov_vf(adev))
    adev->gfx.cp_gfx_shadow = true;

But we need this information for GFX Userqueues, so that user can
create these objects while creating userqueue. This patch series
creates a method to get this information bypassing the dependency
on this check.

This patch:
- adds a new input parameter flag to the gfx.funcs->get_gfx_shadow_info
fptr definition, so that it can accommodate the information without the
check (adev->gfx.cp_gfx_shadow) on request.
- updates the existing definition of amdgpu_gfx_get_gfx_shadow_info to
adjust with this new flag.

Next patch in the series is adding a UAPI which will consume this info.
