When paging queue is enabled, it use the second page of doorbell.
The AMDGPU_DOORBELL64_MAX_ASSIGNMENT definition assumes all the
kernel doorbells are in the first page. So with paging queue enabled,
the total kernel doorbell range should be original num_doorbell plus
one page (0x400 in dword), not *2.

For XGMI hive case do reset in steps where each step iterates over
all devs in hive. This especially important for asic reset
since all PSP FW in hive must come up within a limited time
(around 1 sec) to properply negotiate the link.
Do this by  refactoring  amdgpu_device_gpu_recover and amdgpu_device_reset
into pre_asic_reset, asic_reset and post_asic_reset functions where is part
is exectued for all the GPUs in the hive before going to the next step.

v2: Update names for amdgpu_device_lock/unlock functions.

v3: Introduce per hive locking to avoid multiple resets for GPUs
    in same hive.

Support for AMDGPU specific FreeSync properties and ioctls are dropped
from amdgpu_dm in favor of supporting drm variable refresh rate
properties.

The notify_freesync and set_freesync_property functions are dropped
from amdgpu_display_funcs.

The drm vrr_capable property is now attached to any DP/HDMI connector.
Its value is updated accordingly to the connector's FreeSync capabiltiy.

The freesync_enable logic and ioctl control has has been dropped in
favor of utilizing the vrr_enabled on the drm CRTC. This allows for more
fine grained atomic control over which CRTCs should support variable
refresh rate.

To handle state changes for vrr_enabled it was easiest to drop the
forced modeset on freesync_enabled change. This patch now performs the
required stream updates when planes are flipped.

This is done for a few reasons:

(1) VRR stream updates can be done in the fast update path

(2) amdgpu_dm_atomic_check would need to be hacked apart to check
    desired variable refresh state and capability before the CRTC
    disable pass.

(3) Performing VRR stream updates on-flip is needed for enabling BTR
    support.

VRR packets and timing adjustments are now tracked and compared to
previous values sent to the hardware.

When variable refresh rate is active the hardware counter can return
a position >= vtotal. This results in a vpos being returned from
amdgpu_display_get_crtc_scanoutpos that's a positive value. The
positive value indicates to the caller that the display is
currently in scanout when the display is actually still in vblank.

This is because the vfront porch duration is unknown with variable
refresh active and will end when either a page flip occurs or the
timeout specified by the driver/display is reached.

The behavior of the amdgpu_display_get_crtc_scanoutpos remains the
same when the position is below vtotal. When the position is above
vtotal the function will return a value that is effectively -vbl_end,
the size of the vback porch.

The only caller affected by this change is the DRM helper for
calculating vblank timestamps. This change corrects behavior for
calculating the page flip timestamp from being the previous timestamp
to the calculation to the next timestamp when position >= vtotal.

Adaptive Backlight Management (ABM) is a feature
that reduces backlight level to save power, while
increasing pixel contrast and pixel luminance
to maintain readability and image quality.

ABM will adjust in response to the
pixel luminance of the displayed content.

ABM is made available as a drm property on eDP
monitors called "abm level", which ranges from 0 to 4.
When this property is set to 0, ABM is off.  Levels 1
to 4 represent different ranges of backlight reduction.
At higher levels both the backlight reduction and pixel
adjustment will be greater.

ABM requires DMCU firmware, which is currently available for
Raven ASICs only.  If the feature does not work, please
ensure your firmware is up to date.

v2:
Fix commit message, only attach property if DMCU loaded
v3:
Store ABM level in crtc state to accommodate dc

The adev parameter in amdgpu_sync_fence and amdgpu_sync_resv is only
needed for updating sync->last_vm_update. This breaks if different
adevs are passed to calls for the same sync object.

Always pass NULL for calls from KFD because sync objects used for
KFD don't belong to any particular device, and KFD doesn't need the

Instead of waiting for each KFD BO after validation just wait for the
last BO moving fence.

PD or PT might have to be moved during validation and this move has to be
completed before updating it. If page table updates are done using SDMA
then this serializing is done by SDMA command submission.

And if PD/PT updates are done by CPU, then explicit waiting for PD/PT
updates are done in amdgpu VM amdgpu_vm_wait_pd function.

Sync to PD BO moving fence to handle corner case where none of the PTs
are updated but PD is evicted.

With GFXOFF enabled, this patch will cause PCO amdgpu_test failed,
but GFXOFF is necessary for PCO, so revert the patch.

This reverts commit b83761bb.

[Why]
Many panels support more than 8bpc but some modes are unavailable while
running at greater than 8bpc due to DP/HDMI bandwidth constraints.

Support for more than 8bpc was added recently in the driver but it
defaults to the maximum supported bpc - locking out these modes.

This should be a user configurable option such that the user can select
what bpc configuration they would like.

[How]
This patch introduces the "max bpc" amdgpu driver specific connector
property so the user can limit the maximum bpc. It ranges from 8 to 16.

This doesn't directly set the preferred bpc for the panel since it
follows Intel's existing driver conventions.

This proprety should be removed once common drm support for max bpc
lands.
