Add support to set ISP clocks for SMU v14.0.0. ISP driver
uses amdgpu_dpm_set_soft_freq_range() API to set clocks via
SMU interface than communicating with PMFW directly.
amdgpu_dpm_set_soft_freq_range() is updated to take in any
pp_clock_type than limiting to support only PP_SCLK to allow
ISP and other driver modules to set the min/max clocks. Any
clock specific restrictions are expected to be taken care in
SOC specific SMU implementations instead of generic amdgpu_dpm
and amdgpu_smu interfaces.

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

This patch adds support for userqueue resume. What it typically does is
this:
- adds a new delayed work for resuming all the queues.
- schedules this delayed work from the suspend work.
- validates the BOs and replaces the eviction fence before resuming all
the queues running under this instance of userq manager.
V2: Addressed Christian's review comments:
- declare local variables like ret at the bottom.
- lock all the object first, then start attaching the new fence.
- dont replace old eviction fence, just attach new eviction fence.
- no error logs for drm_exec_lock failures
- no need to reserve bos after drm_exec_locked
- schedule the resume worker immediately (not after 100 ms)

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

This patch introduces new IOCTL for userqueue secure semaphore.
The signal IOCTL called from userspace application creates a drm
syncobj and array of bo GEM handles and passed in as parameter to
the driver to install the fence into it.
The wait IOCTL gets an array of drm syncobjs, finds the fences
attached to the drm syncobjs and obtain the array of
memory_address/fence_value combintion which are returned to
userspace.
v2: (Christian)
- Install fence into GEM BO object.
- Lock all BO's using the dma resv subsystem
- Reorder the sequence in signal IOCTL function.
- Get write pointer from the shadow wptr
- use userq_fence to fetch the va/value in wait IOCTL.
v3: (Christian)
- Use drm_exec helper for the proper BO drm reserve and avoid BO
lock/unlock issues.
- fence/fence driver reference count logic for signal/wait IOCTLs.
v4: (Christian)
- Fixed the drm_exec calling sequence
- use dma_resv_for_each_fence_unlock if BO's are not locked
- Modified the fence_info array storing logic.
v5: (Christian)
- Keep fence_drv until wait queue execution.
- Add dma_fence_wait for other fences.
- Lock BO's using drm_exec as the number of fences in them could
change.
- Install signaled fences as well into BO/Syncobj.
- Move Syncobj fence installation code after the drm_exec_prepare_array.
- Directly add dma_resv_usage_rw(args->bo_flags....
- remove unnecessary dma_fence_put.
v6: (Christian)
- Add xarray stuff to store the fence_drv
- Implement a function to iterate over the xarray and drop
the fence_drv references.
- Add drm_exec_until_all_locked() wrapper
- Add a check that if we haven't exceeded the user allocated num_fences
before adding dma_fence to the fences array.
v7: (Christian)
- Use memdup_user() for kmalloc_array + copy_from_user
- Move the fence_drv references from the xarray into the newly created fence
and drop the fence_drv references when we signal this fence.
- Move this locking of BOs before the "if (!wait_info->num_fences)",
this way you need this code block only once.
- Merge the error handling code and the cleanup + return 0 code.
- Initializing the xa should probably be done in the userq code.
- Remove the userq back pointer stored in fence_drv.
- Pass xarray as parameter in amdgpu_userq_walk_and_drop_fence_drv()
v8: (Christian)
- Move fence_drv references must come before adding the fence to the list.
- Use xa_lock_irqsave_nested for nested spinlock operations.
- userq_mgr should be per fpriv and not one per device.
- Restructure the interrupt process code for the early exit of the loop.
- The reference acquired in the syncobj fence replace code needs to be
kept around.
- Modify the dma_fence acquire placement in wait IOCTL.
- Move USERQ_BO_WRITE flag to UAPI header file.
- drop the fence drv reference after telling the hw to stop accessing it.
- Add multi sync object support to userq signal IOCTL.
V9: (Christian)
- Store all the fence_drv ref to other drivers and not ourself.
- Remove the userq fence xa implementation and replace with
kvmalloc_array.
v10: (Christian)
- Add a comment for the userq_xa xarray
- drop the if check of userq_fence->fence_drv_array
- use the i variable to initialize userq_fence->fence_drv_array_count
- drop the fence reference before you free the array in the error handling,
otherwise it could be that some references leaked.

By replacing VGA_VSTATUS_CNTL by VGA_RENDER_CONTROL__VGA_VSTATUS_CNTL_MASK,
we also need to fix its usage in GMC6.
Note: VGA_VSTATUS_CNTL's binary value was inverted in dce_6_0_sh_mask.h,
so we need to invert its value where it was used.

Dequeue retry timeout controls the interval between checks for unmet
conditions. On MI series, reduce this from 0x40 to 0x1 (~ 1 uS). The
cost of additional bandwidth consumed by CP when polling memory
shouldn't be substantial.

To reset hung SDMA queues on GFX 9.4+ for the GFX9 family, a soft reset
must be issued through SMU. Since soft resets will reset an entire SDMA
engine, use a common KGD call to do the reset as the KGD will handle
avoiding a reset of in flight GFX and paging queues on that engine.
In addition, create a common call for all reset types to simplify
the handling of module parameter settings that block gpu resets.

Upgrading the kernel may cause some systems that were previously not using
a firmware specified brightness curve to use one.
In the event of problems with this curve (for example an interpolation
error) add a new dcdebugmask value that can be used to turn it off. Also
add an info message to show that custom brightness curves are currently in
use.
