 +
** 1: SmException_BptIntReport
 +
** 2: SmException_BptPauseReport
 +
** 3: ErrorNotifierEvent
 +
* /dev/nvhost-ctrl: Used to get events for SyncPts.
 +
** If bit31-28 is 1, then lower 16-bits contain event_slot, bit27-16 contain syncpt_number.
 +
** If bit31-28 is 0, then lower 4-bits contain event_slot, bit31-4 contains syncpt_number.

This sets a boolean value based on the input u64 and the value of the "nv!nv_graphics_firmware_memory_margin" system configuration, but only for "nvdrv" (the other services default to false).
    
Official user-processes starting with 3.0.0 now use this at the end of nvdrv service init with value 0x1.
