* kfd_ioctl_set_xnack_mode_args - Arguments for set_xnack_mode

*
* @xnack_enabled indicates whether recoverable page faults should be
* enabled for the current process. 0 means disabled, positive means
* enabled, negative means leave unchanged. If enabled, virtual address
* translations on GFXv9 and later AMD GPUs can return XNACK and retry
* the access until a valid PTE is available. This is used to implement
* device page faults.
*
* On output, @xnack_enabled returns the (new) current mode (0 or
* positive). Therefore, a negative input value can be used to query
* the current mode without changing it.
*
* The XNACK mode fundamentally changes the way SVM managed memory works
* in the driver, with subtle effects on application performance and
* functionality.
*
* Enabling XNACK mode requires shader programs to be compiled
* differently. Furthermore, not all GPUs support changing the mode
* per-process. Therefore changing the mode is only allowed while no
* user mode queues exist in the process. This ensure that no shader
* code is running that may be compiled for the wrong mode. And GPUs
* that cannot change to the requested mode will prevent the XNACK
* mode from occurring. All GPUs used by the process must be in the
* same XNACK mode.
*
* GFXv8 or older GPUs do not support 48 bit virtual addresses or SVM.
* Therefore those GPUs are not considered for the XNACK mode switch.
*
* Return: 0 on success, -errno on failure
