1 Kernel driver w83627hf 2 ====================== 3 4 Supported chips: 5 * Winbond W83627HF (ISA accesses ONLY) 6 Prefix: 'w83627hf' 7 Addresses scanned: ISA address retrieved from Super I/O registers 8 * Winbond W83627THF 9 Prefix: 'w83627thf' 10 Addresses scanned: ISA address retrieved from Super I/O registers 11 * Winbond W83697HF 12 Prefix: 'w83697hf' 13 Addresses scanned: ISA address retrieved from Super I/O registers 14 * Winbond W83637HF 15 Prefix: 'w83637hf' 16 Addresses scanned: ISA address retrieved from Super I/O registers 17 * Winbond W83687THF 18 Prefix: 'w83687thf' 19 Addresses scanned: ISA address retrieved from Super I/O registers 20 Datasheet: Provided by Winbond on request(http://www.winbond.com/hq/enu) 21 22 Authors: 23 Frodo Looijaard <frodol@dds.nl>, 24 Philip Edelbrock <phil@netroedge.com>, 25 Mark Studebaker <mdsxyz123@yahoo.com>, 26 Bernhard C. Schrenk <clemy@clemy.org> 27 28 Module Parameters 29 ----------------- 30 31 * force_i2c: int 32 Initialize the I2C address of the sensors 33 * init: int 34 (default is 1) 35 Use 'init=0' to bypass initializing the chip. 36 Try this if your computer crashes when you load the module. 37 38 Description 39 ----------- 40 41 This driver implements support for ISA accesses *only* for 42 the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips. 43 We will refer to them collectively as Winbond chips. 44 45 This driver supports ISA accesses, which should be more reliable 46 than i2c accesses. Also, for Tyan boards which contain both a 47 Super I/O chip and a second i2c-only Winbond chip (often a W83782D), 48 using this driver will avoid i2c address conflicts and complex 49 initialization that were required in the w83781d driver. 50 51 If you really want i2c accesses for these Super I/O chips, 52 use the w83781d driver. However this is not the preferred method 53 now that this ISA driver has been developed. 54 55 The w83627_HF_ uses pins 110-106 as VID0-VID4. The w83627_THF_ uses the 56 same pins as GPIO[0:4]. Technically, the w83627_THF_ does not support a 57 VID reading. However the two chips have the identical 128 pin package. So, 58 it is possible or even likely for a w83627thf to have the VID signals routed 59 to these pins despite their not being labeled for that purpose. Therefore, 60 the w83627thf driver interprets these as VID. If the VID on your board 61 doesn't work, first see doc/vid in the lm_sensors package[1]. If that still 62 doesn't help, you may just ignore the bogus VID reading with no harm done. 63 64 For further information on this driver see the w83781d driver documentation. 65 66 [1] http://www.lm-sensors.org/browser/lm-sensors/trunk/doc/vid 67 68 Forcing the address 69 ------------------- 70 71 The driver used to have a module parameter named force_addr, which could 72 be used to force the base I/O address of the hardware monitoring block. 73 This was meant as a workaround for mainboards with a broken BIOS. This 74 module parameter is gone for technical reasons. If you need this feature, 75 you can obtain the same result by using the isaset tool (part of 76 lm-sensors) before loading the driver: 77 78 # Enter the Super I/O config space 79 isaset -y -f 0x2e 0x87 80 isaset -y -f 0x2e 0x87 81 82 # Select the hwmon logical device 83 isaset -y 0x2e 0x2f 0x07 0x0b 84 85 # Set the base I/O address (to 0x290 in this example) 86 isaset -y 0x2e 0x2f 0x60 0x02 87 isaset -y 0x2e 0x2f 0x61 0x90 88 89 # Exit the Super-I/O config space 90 isaset -y -f 0x2e 0xaa 91 92 The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but 93 0x4e/0x4f is also possible. 94 95 Voltage pin mapping 96 ------------------- 97 98 Here is a summary of the voltage pin mapping for the W83627THF. This 99 can be useful to convert data provided by board manufacturers into 100 working libsensors configuration statements. 101 102 W83627THF | 103 Pin | Name | Register | Sysfs attribute 104 ----------------------------------------------------- 105 100 | CPUVCORE | 20h | in0 106 99 | VIN0 | 21h | in1 107 98 | VIN1 | 22h | in2 108 97 | VIN2 | 24h | in4 109 114 | AVCC | 23h | in3 110 61 | 5VSB | 50h (bank 5) | in7 111 74 | VBAT | 51h (bank 5) | in8 112 113 For other supported devices, you'll have to take the hard path and 114 look up the information in the datasheet yourself (and then add it 115 to this document please.)
