 * @op specifies the operation to perform (see enum
 * @kfd_ioctl_svm_op).  @start_addr and @size are common for all

 *
 * A variable number of attributes can be given in @attrs.
 * @nattr specifies the number of attributes. New attributes can be
 * added in the future without breaking the ABI. If unknown attributes
 * are given, the function returns -EINVAL.
 *
 * @KFD_IOCTL_SVM_OP_SET_ATTR sets attributes for a virtual address
 * range. It may overlap existing virtual address ranges. If it does,
 * the existing ranges will be split such that the attribute changes
 * only apply to the specified address range.
 *
 * @KFD_IOCTL_SVM_OP_GET_ATTR returns the intersection of attributes
 * over all memory in the given range and returns the result as the
 * attribute value. If different pages have different preferred or
 * prefetch locations, 0xffffffff will be returned for
 * @KFD_IOCTL_SVM_ATTR_PREFERRED_LOC or
 * @KFD_IOCTL_SVM_ATTR_PREFETCH_LOC resepctively. For
 * @KFD_IOCTL_SVM_ATTR_SET_FLAGS, flags of all pages will be
 * aggregated by bitwise AND. That means, a flag will be set in the
 * output, if that flag is set for all pages in the range. For
 * @KFD_IOCTL_SVM_ATTR_CLR_FLAGS, flags of all pages will be
 * aggregated by bitwise NOR. That means, a flag will be set in the
 * output, if that flag is clear for all pages in the range.
 * The minimum migration granularity throughout the range will be
 * returned for @KFD_IOCTL_SVM_ATTR_GRANULARITY.
 *
 * Querying of accessibility attributes works by initializing the
 * attribute type to @KFD_IOCTL_SVM_ATTR_ACCESS and the value to the
 * GPUID being queried. Multiple attributes can be given to allow
 * querying multiple GPUIDs. The ioctl function overwrites the
 * attribute type to indicate the access for the specified GPU.

/**
 * kfd_ioctl_set_xnack_mode_args - Arguments for set_xnack_mode
 *
 * @xnack_enabled:       [in/out] Whether to enable XNACK mode for this process
 *
 * @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
