+# Prefetch Tuning
+
+The kernel module is a register read/write interface designed based on the Kunpeng chip, which is used to read and configure chip performance optimization parameters at the hardware layer of the CPU.
+
+
+
+## Running Environment
+
+- Hardware: Based on Kunpeng 920 chip
+
+- Operating system: openEuler or EulerOS
+
+## Compilation, Installation, and Uninstallation
+
+```
+make clean && make
+insmod prefetch_tuning.ko
+```
+
+Use the following command to check whether the kernel module is inserted :
+
+```
+lsmod | grep prefetch_tuning
+```
+
+Use the following command to uninstall the kernel module:
+
+```
+rmmod prefetch_tuning
+```
+
+**Uninstalling the module will restore all set parameters to default values.**

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. | 0 ~ 15(Note: 0 represents that outstanding level is 1)
+| 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. | 0 ~ 31(Note: 0 represents that outstanding level is 1) |
+| dvmsnp_perf_en | Whether to enable the outstanding level for the dvmsnp.(Note: After the function is enabled, the dvmsnp outstanding value of the MN is equal to the value of dvmsnp_outstanding.) | 0 (disable), 1 (enable) |
+| dvmreq_perf_en | Whether to enable the outstanding level for the dvmreq.(Note: After the function is enabled, the dvmreq outstanding value of the MN is equal to the value of dvmreq_outstanding.) | 0 (disable), 1 (enable) |
+
+**For details about parameters and the restrictions and relationships between bits of the register, see the related chip manuals.**
+
+## Parameter Configuration
+
+After the module is inserted, a series of virtual file interfaces associated with parameters are generated in `/sys/class/misc/prefetch/`. You can run the `cat` command to obtain the current values of parameters or check whether the configurations take effect. For example:
+
+```
+cat /sys/class/misc/prefetch/policy
+```
+
+Use the `echo` command to change the configuration parameters, for example:
+
+```
+echo 1 > /sys/class/misc/prefetch/policy
+```
+
+If the manually configured value is incorrect (Invalid value, for example, the value is out of range), the configuration may fail. In this case, you can view the system log to check whether the value is modified.
+
+> Note: For some parameters, such as policy, the configurations of all CPU cores will be listed when the parameters are obtained. The configurations of all CPU cores will be modified when the parameters are modified.
