/**
* kfd_ioctl_spm_args - Arguments for SPM ioctl
*
* @op[in]: specifies the operation to perform
* @gpu_id[in]: GPU ID of the GPU to profile
* @dst_buf[in]: used for the address of the destination buffer
* in @KFD_IOCTL_SPM_SET_DEST_BUFFER
* @buf_size[in]: size of the destination buffer
* @timeout[in/out]: [in]: timeout in milliseconds, [out]: amount of time left
* `in the timeout window
* @bytes_copied[out]: amount of data that was copied to the previous dest_buf
* @has_data_loss: boolean indicating whether data was lost
* (e.g. due to a ring-buffer overflow)
*
* This ioctl performs different functions depending on the @op parameter.
*
* KFD_IOCTL_SPM_OP_ACQUIRE
* ------------------------
*
* Acquires exclusive access of SPM on the specified @gpu_id for the calling process.
* This must be called before using KFD_IOCTL_SPM_OP_SET_DEST_BUF.
*
* KFD_IOCTL_SPM_OP_RELEASE
* ------------------------
*
* Releases exclusive access of SPM on the specified @gpu_id for the calling process,
* which allows another process to acquire it in the future.
*
* KFD_IOCTL_SPM_OP_SET_DEST_BUF
* -----------------------------
*
* If @dst_buf is NULL, the destination buffer address is unset and copying of counters
* is stopped.
*
* If @dst_buf is not NULL, it specifies the pointer to a new destination buffer.
* @buf_size specifies the size of the buffer.
*
* If @timeout is non-0, the call will wait for up to @timeout ms for the previous
* buffer to be filled. If previous buffer to be filled before timeout, the @timeout
* will be updated value with the time remaining. If the timeout is exceeded, the function
* copies any partial data available into the previous user buffer and returns success.
* The amount of valid data in the previous user buffer is indicated by @bytes_copied.
*
* If @timeout is 0, the function immediately replaces the previous destination buffer
* without waiting for the previous buffer to be filled. That means the previous buffer
* may only be partially filled, and @bytes_copied will indicate how much data has been
* copied to it.
*
* If data was lost, e.g. due to a ring buffer overflow, @has_data_loss will be non-0.
*
* Returns negative error code on failure, 0 on success.
