1 Kernel driver nct7904 2 ==================== 3 4 Supported chip: 5 * Nuvoton NCT7904D 6 Prefix: nct7904 7 Addresses: I2C 0x2d, 0x2e 8 Datasheet: Publicly available at Nuvoton website 9 http://www.nuvoton.com/ 10 11 Author: Vadim V. Vlasov <vvlasov@dev.rtsoft.ru> 12 13 14 Description 15 ----------- 16 17 The NCT7904D is a hardware monitor supporting up to 20 voltage sensors, 18 internal temperature sensor, Intel PECI and AMD SB-TSI CPU temperature 19 interface, up to 12 fan tachometer inputs, up to 4 fan control channels 20 with SmartFan. 21 22 23 Sysfs entries 24 ------------- 25 26 Currently, the driver supports only the following features: 27 28 in[1-20]_input Input voltage measurements (mV) 29 30 fan[1-12]_input Fan tachometer measurements (rpm) 31 32 temp1_input Local temperature (1/1000 degree, 33 0.125 degree resolution) 34 35 temp[2-9]_input CPU temperatures (1/1000 degree, 36 0.125 degree resolution) 37 38 pwm[1-4]_enable R/W, 1/2 for manual or SmartFan mode 39 Setting SmartFan mode is supported only if it has been 40 previously configured by BIOS (or configuration EEPROM) 41 42 pwm[1-4] R/O in SmartFan mode, R/W in manual control mode 43 44 The driver checks sensor control registers and does not export the sensors 45 that are not enabled. Anyway, a sensor that is enabled may actually be not 46 connected and thus provide zero readings. 47 48 49 Limitations 50 ----------- 51 52 The following features are not supported in current version: 53 54 - SmartFan control 55 - Watchdog 56 - GPIO 57 - external temperature sensors 58 - SMI 59 - min/max values 60 - many other...
