127		reg_prefetchtgt_level	Threshold for the HHA to read data from the DDR prefetch. When the DDR read/write operations in the HHA processing queue exceed the threshold, the prefetchtgt operation is forbidden to read the DDR data and the operation is directly discarded.

130		dvmsnp_outstanding	Outstanding value of the DVMSNP of the MN. Note 1: If dvmsnp_perf_en is enabled, the configured value is valid. The maximum value of outstanding can be 5 when the TaiShan core is used. Otherwise, overflow errors occur. Note 2: The SMMU cannot match the Dvmsnp outstanding value 5. Therefore, you need to set the switch to 3 for Totem and Infinite of 1383. Totem and Nimbus of 1620: Set DVM outstanding to 5. However, do not configure POE for the DVMSNP broadcast node. The POE uses a private page table and does not require DVMSNP. Range from 0 to 15.(Note: 0 represents that outstanding level is 1)	cat /sys/class/misc/prefetch/@name	echo $value > /sys/class/misc/prefetch/@name	FALSE	discrete		int	0	15	1		yes
131		dvmreq_outstanding	Outstanding value of the DVMREQ of the MN. Note 1: If dvmreq_perf_en is enabled, the configured value is valid. The maximum value of outstanding can be 9 when there are four chips. Otherwise, an overflow error occurs. Note 2: In the case of two chips, the maximum outstanding value of totem can be 10, and the maximum outstanding value of nimbus or infinite is 24. This ensures the best performance. Note 3: In the case of a single chip, there is no restriction on the outstanding configuration of the totem. Range from 0 to 31.(Note: 0 represents that outstanding level is 1)	cat /sys/class/misc/prefetch/@name	echo $value > /sys/class/misc/prefetch/@name	FALSE	discrete		int	0	31	1		yes
