QCA6174方案说明

Thermal mitigation on WLAN involves monitoring the temperature of the WLAN chip, detecting when a threshold is crossed, and taking necessary actions to reduce the temperature.

– Four levels of temperature threshold ranges are configured by the following WCNSS_qcom_cfg.ini file parameters (in /lib/firmware/wlan/qca_cld.) Based on the threshold range chosen, the WLAN driver controls bus idle time to throttle the throughput and reduce WLAN chip temperature.

– Level 0 range: gThermalTempMinLevel0, gThermalTempMaxLevel0– Level 1 range: gThermalTempMinLevel1, gThermalTempMaxLevel1– Level 2 range: gThermalTempMinLevel2, gThermalTempMaxLevel2– Level 3 range: gThermalTempMinLevel3, gThermalTempMaxLevel3– On QCA61x7(A), an on-chip temperature sensor is used to monitor the temperature.– The architecture of the thermal mitigation feature is as follows:– When either a MinLevel or MaxLevel temperature threshold is crossed the WLAN firmware
