DEDICATED_PATH_ARB_CREDITS (Dedicated Path Arbiter Credits)

This register has bits that are reserved but not MBZ (must be zero). So, it

can only be safely updated via read-modify-write operations.

Starting with Tiger Lake, the Display Engine has a dedicated path to memory

through the processor's fabric. This dedicated path is intended to ensure

that the Display Engine's latency requirements are met even under heavy

memory contention.

This register configures the credits are used for arbitrating between ABOXes

(Arbiter Boxes) for streaming HP (high-priority) traffic to the dedicated

memory path.
