We need to make sure the workload profile ref counts are

increment the count on submissions, but the decrement may
be delayed as work comes in.  Track when we enable the

Add helpers to switch the workload profile dynamically when
commands are submitted.  This allows us to switch to
the FULLSCREEN3D or COMPUTE profile when work is submitted.
Add a delayed work handler to delay switching out of the
selected profile if additional work comes in.  This works
the same as the VIDEO profile for VCN.  This lets dynamically
enable workload profiles on the fly and then move back
to the default when there is no work.

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.

V2: split this patch from the new UAPI patch

This commit introduces the Enforce Isolation Handler designed to enforce
shader isolation on AMD GPUs, which helps to prevent data leakage
between different processes.

The handler counts the number of emitted fences for each GFX and compute
ring. If there are any fences, it schedules the `enforce_isolation_work`
to be run after a delay of `GFX_SLICE_PERIOD`. If there are no fences,
it signals the Kernel Fusion Driver (KFD) to resume the runqueue.

The function is synchronized using the `enforce_isolation_mutex`.

This commit also introduces a reference count mechanism
(kfd_sch_req_count) to keep track of the number of requests to enable
the KFD scheduler. When a request to enable the KFD scheduler is made,
the reference count is decremented. When the reference count reaches
zero, a delayed work is scheduled to enforce isolation after a delay of
GFX_SLICE_PERIOD.

When a request to disable the KFD scheduler is made, the function first
checks if the reference count is zero. If it is, it cancels the delayed
work for enforcing isolation and checks if the KFD scheduler is active.
If the KFD scheduler is active, it sends a request to stop the KFD
scheduler and sets the KFD scheduler state to inactive. Then, it
increments the reference count.

The function is synchronized using the kfd_sch_mutex to ensure that the
KFD scheduler state and reference count are updated atomically.

This commit adds a new sysfs attribute 'enforce_isolation' to control
the 'enforce_isolation' setting per GPU. The attribute can be read and
written, and accepts values 0 (disabled) and 1 (enabled).

When 'enforce_isolation' is enabled, reserved VMIDs are allocated for
each ring. When it's disabled, the reserved VMIDs are freed.

The set function locks a mutex before changing the 'enforce_isolation'
flag and the VMIDs, and unlocks it afterwards. This ensures that these
operations are atomic and prevents race conditions and other concurrency
issues.
