To keep self heating below 0.1 degree +Celsius, the device should not be active for more than 10% of the time. For +this reason, the driver performs no more than two measurements per second and +reports cached information if polled more frequently. + +Different resolutions, the on-chip heater, using the CRC checksum and reading +the serial number are not supported yet. diff --git a/Documentation/hwmon/k10temp b/Documentation/hwmon/k10temp index 90956b618025..4dfdc8f83633 100644 --- a/Documentation/hwmon/k10temp +++ b/Documentation/hwmon/k10temp @@ -12,6 +12,7 @@ Supported chips: * AMD Family 12h processors: "Llano" (E2/A4/A6/A8-Series) * AMD Family 14h processors: "Brazos" (C/E/G/Z-Series) * AMD Family 15h processors: "Bulldozer" (FX-Series), "Trinity" +* AMD Family 16h processors: "Kabini" Prefix: 'k10temp' Addresses scanned: PCI space |
