       radeon_atif_notification_cfg *n );

• n — atif notification configuration struct, aka your struct radeon_atif_notification_cfg *n bestie.

💅 DESCRIPTION 💅

okay so radeon_atif_get_notification_params executes the ATIF_FUNCTION_GET_SYSTEM_PARAMETERS ATIF function to determine if a notifier is used, and if it is, which one. this is for all asics, no cap.

the notifier is either Notify(VGA, 0x81) or Notify(VGA, n), where n is specified in the result if a notifier is used. 💅

it returns 0 on success, and an error on failure. that's the vibe check, periodt.
