The dependency is:

v1: Add generic amdgpu_reset_control to handle different types of resets. It
may be added at device, hive or ip level. Each reset control has a list
of handlers associated with it to handle different types of reset. Reset
control is responsible for choosing the right handler given a particular
reset context.

Handler objects may implement a set of functions on how to handle a
particular type of reset.

prepare_env = Prepare environment/software context (not used currently).
prepare_hwcontext = Prepare hardware context for the reset.
perform_reset = Perform the type of reset.
restore_hwcontext = Restore the hw context after reset.

Reset context carries the context of reset, as of now this is based on

[Why]
This option shall be opt-in by default since it is a temporary solution
until long term solution is agreed upon which may require userspace interface
changes. This feature give the user a seamless experience when freesync aware
programs (media players for instance) switches to a compatible freesync mode
when playing videos. Enabling this feature also have the potential side effect
of causing higher power consumption due to running a mode with lower resolution
and base clock frequency with the highest base clock supported on the monitor as
per its advertised modes. There has been precedent of manufacturing modes in the
kernel. In AMDGPU, the existing usage are for common modes and scaling modes.
Other driver have a similar approach as well.

[How]
Adds a module parameter to enable freesync video mode modeset
optimization. Enabling this mode allows the driver to skip a full modeset when a
freesync compatible mode is requested by the userspace. This parameter will also
add some additional modes that are within the connected monitor's VRR range
corresponding to common video modes, which media players can use for a seamless
experience while making use of freesync.
