From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: drivers: hv: dxgkrnl: Manage device allocation properties
Implement ioctls to manage properties of a compute device allocation:
- LX_DXUPDATEALLOCPROPERTY,
- LX_DXSETALLOCATIONPRIORITY,
- LX_DXGETALLOCATIONPRIORITY,
- LX_DXQUERYALLOCATIONRESIDENCY.
- LX_DXCHANGEVIDEOMEMORYRESERVATION,
The LX_DXUPDATEALLOCPROPERTY ioctl requests the host to update
various properties of a compute devoce allocation.
The LX_DXSETALLOCATIONPRIORITY and LX_DXGETALLOCATIONPRIORITY ioctls
are used to set/get allocation priority, which defines the
importance of the allocation to be in the local device memory.
The LX_DXQUERYALLOCATIONRESIDENCY ioctl queries if the allocation
is located in the compute device accessible memory.
The LX_DXCHANGEVIDEOMEMORYRESERVATION ioctl changes compute device
memory reservation of an allocation.
