Change History
--------------
v4: Changes suggested by Emil, Christian
- return -ENODATA for asics with unlimited sessions
v3: changes suggested by Christian
- Add a check for UVD IP block using AMDGPU_HW_IP_UVD
query type.
- Add a check for asic_type to be less than
CHIP_POLARIS10 since starting Polaris, we support
unlimited UVD instances.
- Add kerneldoc style comment for
amdgpu_uvd_used_handles().
v2: as suggested by Christian
- Add a new query AMDGPU_INFO_NUM_HANDLES
- Create a helper function to return the number
of currently used UVD handles.
- Modify the logic to count the number of used
UVD handles since handles can be freed in
non-linear fashion.
v1:
- User might want to query the maximum number of UVD
instances supported by firmware. In addition to that,
if there are multiple applications using UVD handles
at the same time, he might also want to query the
currently used number of handles.
For this we add two variables max_handles and
used_handles inside drm_amdgpu_info_hw_ip. So now
an application (or libdrm) can use AMDGPU_INFO IOCTL
with AMDGPU_INFO_HW_IP_INFO query type to get these
values.

drm/probe-helpers: Drop locking from poll_enable

drm/probe-helper: Grab mode_config.mutex in poll_init/enable
Unfortunately the commit message of that patch fails to mention that
the new locking check was for the connector_list.
But that requirement disappeared in

and so we can drop this again.
This fixes a locking inversion on nouveau, where the rpm code needs to
re-enable. But in other places the rpm_get() calls are nested within
the big modeset locks.
While at it, also improve the kerneldoc for these two functions a
notch.
v2: Update the kerneldoc even more to explain that these functions
can't be called concurrently, or bad things happen (Chris).

When we reach the user's RPS limits, stop requesting an adjustment. Even
though we will clamp the requested frequency later, we rely on interrupt
masking to disable further adjustments in the same direction. Even
though it is unlikely (one scenario is a bug in the driver, another is
careful manipulation through the uAPI) if we keep exponentially
increasing the adjustment value, it will wrap and cause a negative
adjustment.

The only tricky part is to ensure TTM debugfs initialization happens
after the debugfs root node is created, which is done by moving that
code into the debufs_init() hook.

With the introduce of i915_vma_instance() for obtaining the VMA
singleton for a (obj, vm, view) tuple, we can remove the
i915_vma_create() in favour of a single entry point. We do incur a
lookup onto an empty tree, but the i915_vma_create() were being called
infrequently and during initialisation, so the small overhead is
negligible.
v2: Drop the i915_ prefix from the now static vma_create() function

Just as added paranoia against our future-selves add another check that
the lookup/created VMA instance matches the request.

Whilst writing testcases to exercise the VMA API, some oddities came to
light, such as i915_gem_obj_lookup_or_create(). Joonas suggested
i915_vma_instance() as a neat replacement, so rename them, move them to
i915_vma.c and add some kerneldoc as a sugary bonus.

With atomic plane states we are able to track an allocation right from
preparation, during use and through to the final free after being
swapped out for a new plane. We can couple the VMA we pin for the
framebuffer (and its rotation) to this lifetime and avoid all the clumsy
lookups in between.
v2: Remove residual vma on plane cleanup (Chris)
v3: Add a description for the vma destruction in
intel_plane_destroy_state (Maarten)

This patch will allow for getparams to return the status of the HuC.
As the HuC has to be validated by the GuC this patch uses the validated
status to show when the HuC is loaded and ready for use. You cannot use
the loaded status as with the GuC as the HuC is verified after it is
loaded and is not usable until it is verified.
v2: removed the forewakes as the registers are already force-woken.
(T.Ursulin)
v3: rebased on top of drm-tip. Removed any reference to intel_huc.h
v4: rebased. Rename I915_PARAM_HAS_HUC to I915_PARAM_HUC_STATUS.
Remove intel_is_huc_valid() since it is used only in one place.
Put the case of I915_PARAM_HAS_HUC() in the right place.
v5: rebased. Add a comment to specify that I915_READ(reg)
does not read garbage value. The register HUC_STATUS2 is force
woken and no rpm is needed.

The HuC authentication is done by host2guc call. The HuC RSA keys
are sent to GuC for authentication.
v2: rebased on top of drm-tip. Changed name format and upped
version 1.7.
v3: changed wait_for_atomic to wait_for
v4: rebased. Rename intel_huc_auh() to intel_guc_auth_huc()
and place the prototype in intel_guc.h,correct the comments.
v5: rebased. Moved intel_guc_auth_huc from i915_guc_submission.c
to intel_uc.c.Update dev to dev_priv in intel_guc_auth_huc().
Renamed HOST2GUC_ACTION_AUTHENTICATE_HUC TO INTEL_GUC_ACTION_
AUTHENTICATE_HUC
v6: rebased. Add newline on DRM_ERRORs that already dont have one.
v7: rebased. Replace wait_for with intel_wait_for_register() since
the latter employs sleep optimisations for quick responses- as pointed
out by Chris Wilson.
v8: rebased. Cleanup the intel_guc_auth_huc() by removing checks
already performed in earlier functions. Make comments more descriptive.
v9: rebased. Changed the bias for pinning the HuC object. Move
intel_guc_auth_huc() to intel_huc.c. Change DRM_DEBUGs to DRM_ERRORs
in intel_guc_auth_huc(). Add return status to DRM_ERRORs.
v10: Remove message not required for the user..
